Quick Answer: Long-Term Antacid Use Side Effects

Long-term antacid use — particularly proton pump inhibitors (PPIs) like omeprazole, esomeprazole, and pantoprazole — is associated with nutrient deficiencies (vitamin B12, magnesium, calcium), increased fracture risk, kidney disease, recurrent infections, and potential gut microbiome disruption. Although generally safe and effective, studies suggest that long-term use may reduce levels of vitamin B12, magnesium, and calcium in the body and increase the risk of hip fractures. Short-term use is safe — but daily antacid use beyond 8–14 weeks without medical supervision carries real and documented risks.

What Are Antacids?

Antacids are medications that reduce or neutralize stomach acid — used to treat heartburn, acid reflux, GERD (gastroesophageal reflux disease), and peptic ulcers. They are among the most commonly used medications worldwide — available over the counter and by prescription.

Key distinction: “Antacid” is an umbrella term covering three mechanistically different drug classes — each with different side effect profiles and different long-term risk levels.

Three Types of Antacids — Critical Differences

PPIs are among the most prescribed drugs worldwide owing to their proven efficacy in symptom control and mucosal healing for acid-related disorders. However, long-term use beyond approved indications is increasingly common and has raised safety concerns. MDPI

Why Stomach Acid Matters

Stomach acid is not simply a digestive problem to be suppressed — it performs essential biological functions:

• Activates pepsin — the enzyme initiating protein digestion
• Sterilizes food — killing ingested bacteria and pathogens
• Enables absorption of vitamin B12, iron, calcium, and magnesium
• Maintains appropriate gut microbiome composition
• Signals appropriate digestive hormone release

Normal gastric pH is necessary to activate pepsin enzyme, which acts on proteins to initiate protein digestion, and is also necessary for the absorption of vitamin C and B12 in the gastrointestinal tract. Long-term acid suppression disrupts all of these functions simultaneously. Agdbio

How Long Is “Long-Term” Use?

For short-term treatment — usually 4 to 8 weeks — PPIs are considered very safe and highly effective. Many people with GERD stay on PPIs for months or years, sometimes without reassessment. Ubie

 

Side Effects of Long-Term Antacid Use — Complete Evidence Review

---

1. Nutrient Deficiencies — Most Common and Most Significant

Nutrient deficiency is the most clinically consistent and best-documented consequence of long-term acid suppression — particularly with PPIs.

---

Vitamin B12 Deficiency

Stomach acid is required to separate vitamin B12 from food proteins — a process called proteolysis. Without adequate acid, dietary B12 cannot be cleaved from its protein carriers and remains unabsorbed.

One of the earliest long-term side effects of PPIs to be discovered after the drugs were approved was an association with vitamin B12 deficiency. B12 deficiency is common in older adults, as is GERD. MedShadow Foundation

Clinical consequences of B12 deficiency:

• Megaloblastic anemia — fatigue, weakness, pallor
• Peripheral neuropathy — tingling and numbness in hands and feet
• Cognitive impairment — memory problems, confusion
• Subacute combined degeneration of the spinal cord — in severe, prolonged deficiency

Risk is highest in: Older adults, vegetarians, people on PPIs beyond 2 years.

---

Magnesium Deficiency (Hypomagnesemia)

Long-term acid suppression can impair the absorption of vital nutrients such as Vitamin B12, magnesium, and iron, potentially leading to related health issues. Wellri

The FDA issued a safety communication in 2011 requiring PPI labels to warn about hypomagnesemia risk with long-term use. Magnesium deficiency from PPIs typically appears after 12+ months of use.

Clinical consequences:

• Muscle cramps and spasms
• Cardiac arrhythmias — potentially serious
• Fatigue and weakness
• Seizures in severe cases
• Worsening of other electrolyte imbalances — particularly potassium and calcium

---

Calcium Deficiency and Bone Density Loss

Calcium absorption in the intestine requires an acidic environment — particularly for calcium carbonate, the form found in most dietary sources. Prolonged acid suppression impairs calcium absorption — reducing bone mineral density over time.

One of the most well-documented long-term risks is an increased risk of bone fractures, particularly of the hip, spine, and wrist. This risk appears to be higher with high doses and long-term use (over one year). The proposed mechanism is that reduced stomach acid may impair the absorption of calcium, a mineral essential for bone health. Wellri

---

Iron Deficiency

Non-heme iron — from plant sources — requires acidic conditions for conversion to its absorbable form (ferrous iron). Long-term acid suppression impairs non-heme iron absorption — contributing to iron deficiency anemia, particularly in women and vegetarians.

---

2. Bone Fractures — FDA-Warned Risk

Some of the concerns associated with long-term use include a higher risk of fracture because of interference with calcium absorption, an increased risk of certain infections (including pneumonia and C. difficile), and nutritional deficiencies (including magnesium, iron, and vitamin B12). All of these are presumed to be related to the effects of decreased stomach acid production. Yale Medicine

What the evidence shows:

The FDA issued a safety communication in 2010 requiring PPIs to carry fracture warnings after multiple studies demonstrated increased hip, wrist, and spine fracture risk with prolonged use — particularly in:

• People over 50
• People on high-dose PPIs
• People using PPIs for more than one year
• Postmenopausal women — already at elevated osteoporosis risk

Mechanism: Reduced calcium absorption + possible direct effects on osteoclast activity → reduced bone mineral density → increased fracture risk.

Risk magnitude: Studies report 10–40% increased fracture risk with long-term PPI use compared to non-users — highest for hip fractures.

---

3. Kidney Disease — Emerging Serious Concern

Studies have suggested a link between long-term PPI use and an increased risk of both acute interstitial nephritis (a sudden inflammation of the kidneys) and chronic kidney disease (CKD). While the absolute risk is relatively small, it’s a significant concern for individuals already at risk for kidney problems. Wellri

Chronic use of proton pump inhibitors (PPIs), although effective for acid-related disorders, has raised concerns regarding their association with various long-term adverse health outcomes, including cognitive decline, chronic kidney disease, bone fractures, and cardiovascular events. nih

Two kidney conditions associated with long-term PPI use:

Acute Interstitial Nephritis (AIN): An immune-mediated kidney inflammation that can occur at any point during PPI use — not dose-dependent. Presents with declining kidney function, sometimes with fever and rash. Requires immediate discontinuation and medical evaluation.

Chronic Kidney Disease (CKD): Multiple large observational studies and a 2025 systematic review report associations between long-term PPI use and increased CKD risk. The mechanism is not fully established — may involve repeated episodes of subclinical AIN, magnesium deficiency-related kidney effects, or direct tubular toxicity.

---

4. Increased Infection Risk

Stomach acid is a primary defense against ingested pathogens. The long-term acid suppression by PPIs can also lead to enteric, respiratory and urinary tract infections. PubMed

Clostridioides difficile (C. diff) Infection: The most clinically significant infection risk. Gastric acid normally kills C. diff spores — acid suppression allows them to survive and colonize. Observational studies link chronic PPI use to a myriad of adverse outcomes such as enteric infections (e.g., Clostridioides difficile), nutrient deficiencies (magnesium, vitamin B12), osteoporotic fractures, chronic kidney disease, dementia, and gastric and colorectal cancer. MDPI

C. diff infection causes severe, potentially life-threatening diarrhea — particularly dangerous in older adults and hospitalized patients.

Community-Acquired Pneumonia: Gastric acid suppression allows bacteria to colonize the upper GI tract and potentially aspirate into the lungs — increasing pneumonia risk, particularly in older adults.

Small Intestinal Bacterial Overgrowth (SIBO): Reduced acid allows bacteria to colonize the small intestine — normally kept relatively sterile by gastric acidity. SIBO causes bloating, diarrhea, malabsorption, and nutritional deficiencies.

---

5. Rebound Acid Hypersecretion — The Dependency Problem

One of the most clinically underrecognized consequences of long-term PPI use is acid rebound — making it difficult to stop the medication.

How it happens: Long-term acid suppression causes the stomach to upregulate acid-producing machinery — increasing the number and sensitivity of proton pumps. When PPIs are stopped abruptly, this upregulated system produces significantly more acid than before treatment — causing rebound heartburn worse than the original symptoms.

Stopping suddenly after prolonged use can also have a rebound effect and worsen heartburn symptoms. University Hospitals

This rebound effect convinces patients they still need the medication — creating a cycle of long-term use that continues beyond the point of medical necessity. Studies show rebound acid hypersecretion can persist for 2–4 weeks after stopping PPIs.

Clinical implication: PPIs should always be tapered gradually — not stopped abruptly — after long-term use.

🩺 Dr. Rajesh Sharma, MBBS says: “Rebound hypersecretion is the reason so many patients feel they ‘can’t live without’ their PPI. Every time they try to stop, the heartburn comes back worse — so they restart. But that rebound is a withdrawal effect, not proof that they still need the drug. A structured 6-week taper with lifestyle changes allows the vast majority of patients to discontinue successfully.”

---

6. Gut Microbiome Disruption

Stomach acid plays a critical role in regulating gut microbiome composition — acting as a selective barrier that prevents non-acid-tolerant bacteria from reaching the intestine. Long-term acid suppression fundamentally alters this gatekeeper function.

Research shows long-term PPI use is associated with:

• Reduced gut microbiome diversity
• Increased oral bacteria in the intestinal tract
• Increased Enterococcus and other pathogenic species
• Reduced beneficial Bifidobacterium and Lactobacillus populations

These microbiome changes may contribute to the increased infection risk, SIBO, and potentially longer-term systemic effects associated with chronic PPI use.

---

7. Dementia Risk — Contested Evidence

In recent years, there have been observational studies about a potential increased risk of dementia, kidney disease, and heart disease, but those findings have been inconsistent. Yale Medicine

Early observational studies raised concern about PPI use and dementia risk — but more recent and higher quality research has not confirmed a causal relationship.

A 2024 Mendelian randomization study similarly found no robust causal link between PPI use and dementia risk. These findings suggest that earlier associations were likely correlational and subject to confounding; the evidence does not support a causal relationship between PPIs and dementia. MDPI

Current clinical position: Dementia risk from PPI use is not established as causal. People who require PPIs for genuine medical indications should not avoid them based on dementia concern — but unnecessary long-term use remains unjustified.

---

8. Gastric Cancer Risk — Long-Term Concern

A significant population-based study demonstrated that long-term PPI use after Helicobacter pylori eradication was associated with gastric cancer (HR: 2.44, 95% CI: 1.42–4.20), suggesting a dose-duration relationship. These results are from a retrospective cohort and do not establish causality; confounding factors like underlying gastric atrophy may contribute. 

The mechanism proposed: Long-term acid suppression elevates gastrin — the hormone stimulating acid production — potentially driving gastric cell proliferation. This effect may be particularly relevant in people with H. pylori infection and underlying gastric atrophy.

Clinical implication: People requiring long-term PPIs should be screened for H. pylori and treated if positive — as H. pylori eradication reduces gastric cancer risk independent of acid suppression.

---

9. Side Effects by Antacid Type

Classic Antacids (Calcium Carbonate, Magnesium Hydroxide, Aluminum Hydroxide)

Most adverse effects from antacids are minor with periodic use of small amounts. However, when large doses are taken for long periods of time, significant adverse effects may occur especially in patients with underlying diseases such as chronic renal failure. PubMed

Drug Interactions With Long-Term Antacids

All antacids can produce drug interactions by changing gastric pH, thus altering drug dissolution of dosage forms, reduction of gastric acid hydrolysis of drugs, or alter drug elimination by changing urinary pH. Most antacids, except sodium bicarbonate, may decrease drug absorption by adsorption or chelation of other drugs. PubMed

Clinically Significant Interactions:

Signs You May Be Experiencing Long-Term Antacid Side Effects

These symptoms in people on long-term antacids warrant blood testing and medical review:

Nutrient Deficiency Signs:

• Persistent fatigue and weakness — B12, iron, or magnesium deficiency
• Tingling or numbness in hands and feet — B12 neuropathy
• Muscle cramps or spasms — magnesium deficiency
• Irregular heartbeat — magnesium deficiency
• Brittle nails and hair loss — iron deficiency

Infection Signs:

• Persistent or recurrent diarrhea — possible C. diff
• Frequent respiratory infections
• Bloating, gas, and altered bowel habits — possible SIBO

Bone Health Signs:

• Bone pain — particularly lower back and hips
• Fracture from minor trauma
• Diagnosed osteopenia or osteoporosis while on long-term PPIs

Kidney Signs:

• Reduced urine output
• Swelling in legs or ankles
• Fatigue with elevated creatinine on blood tests

---

How to Safely Reduce or Stop Long-Term Antacid Use

Stopping PPIs abruptly after long-term use causes rebound acid hypersecretion — making symptoms worse and reinforcing the belief that the medication is still needed. A gradual tapering strategy is essential.

---

Step-Down Protocol

Always discuss tapering with your prescribing physician — do not self-taper if on PPIs for Barrett’s esophagus, severe GERD, or peptic ulcers.

---

Lifestyle Changes That Reduce Acid Reflux

Addressing the underlying cause reduces dependence on acid suppression:

• Weight loss — even 5–10% body weight reduction significantly reduces GERD symptoms
• Elevate head of bed — 15–20cm elevation reduces nighttime reflux
• Avoid trigger foods — coffee, alcohol, spicy foods, citrus, tomatoes, chocolate, fatty meals
• Eat smaller meals — large meals distend the stomach and increase reflux
• Avoid eating 3 hours before bed — prevents nighttime acid exposure
• Quit smoking — smoking relaxes the lower esophageal sphincter
• Avoid tight clothing — increases abdominal pressure

---

Medical Monitoring for Long-Term Antacid Users

People who genuinely require long-term acid suppression should have regular monitoring to detect complications early.

Recommended Monitoring Schedule:

---

Natural Ways to Reduce Acid Reflux Without Overusing Antacids

Foods to Avoid

These foods relax the lower esophageal sphincter or increase acid production:

• Coffee and caffeine
• Alcohol — especially beer and wine
• Chocolate
• Mint and peppermint
• Fatty and fried foods
• Spicy foods
• Citrus fruits and tomatoes
• Carbonated drinks
• Onions and garlic

Best Foods for Acid Reflux

• Oatmeal and whole grains
• Non-citrus fruits (bananas, melons, apples)
• Green vegetables (broccoli, asparagus, spinach)
• Lean protein (chicken, turkey, fish)
• Ginger — natural anti-inflammatory
• Aloe vera juice (inner leaf only)
• Low-fat dairy or plant-based alternatives

Weight Loss and Lifestyle Changes

Excess body weight is one of the strongest modifiable risk factors for acid reflux. Abdominal fat increases intra-abdominal pressure, pushing stomach contents upward. Losing even 5–10% of body weight significantly reduces reflux frequency in overweight individuals.

• Eat smaller, more frequent meals instead of large meals
• Do not eat within 3 hours of bedtime
• Chew food slowly and thoroughly
• Avoid lying down for at least 2 hours after eating

Sleep Position Tips

• Elevate the head of the bed by 15–20 cm (6–8 inches) — this uses gravity to keep stomach acid where it belongs
• Sleep on the left side — the stomach curves to the left, and left-side sleeping keeps the stomach below the esophagus
• Avoid eating late at night

Stress Management

Stress increases stomach acid production and worsens reflux through the gut-brain connection. Effective stress management can significantly reduce reflux frequency:

• Regular aerobic exercise (30 minutes daily)
• Deep breathing and meditation
• Adequate sleep (7–9 hours)
• Reducing excess caffeine — more than 2–3 cups daily increases acid production

Real-Life Clinical Observations

Based on clinical observations from Dr. Rajesh Sharma, MBBS, General Physician

Case 1: “Ten Years on Omeprazole — Nobody Had Checked His B12”

A 67-year-old retired teacher presented with progressive fatigue, memory difficulties, and tingling in both feet over 18 months. He had been on omeprazole 20mg daily for 10 years — with excellent symptom control. His serum B12 was 98 pg/mL — severely deficient (normal: 200–900). Neurological examination confirmed early peripheral neuropathy.

He received intramuscular B12 injections monthly. His fatigue and tingling improved substantially over 6 months — but some neurological changes persisted.

Lesson: Annual B12 monitoring in anyone on PPIs beyond 2 years is simple, inexpensive, and prevents potentially irreversible neurological damage.

Case 2: “She Couldn’t Stop Her Antacid — Rebound Was the Reason”

A 44-year-old woman had been taking pantoprazole 40mg daily for 3 years for mild reflux. Every time she tried to stop, her heartburn returned within days — worse than before. A structured 6-week step-down protocol with dietary modifications allowed her to discontinue completely.

Lesson: A significant proportion of long-term PPI users are maintained by rebound hypersecretion rather than genuine ongoing disease.

Case 3: “The Hip Fracture Nobody Connected to the Antacid”

A 72-year-old woman with osteoporosis suffered a hip fracture after a minor fall — despite being on alendronate for osteoporosis. She was also on omeprazole 20mg daily for 8 years, taking both medications simultaneously each morning. The PPI was reducing alendronate absorption and impairing calcium absorption at the same time.

Lesson: Long-term PPIs can directly undermine osteoporosis treatment through two simultaneous mechanisms.

When to See a Doctor About Your Antacid Use

🔴 Seek Immediate Medical Attention If:

• Severe or bloody diarrhea after starting or while on PPIs — possible C. diff infection
• Muscle spasms, irregular heartbeat, or seizures — possible severe hypomagnesemia
• Significantly reduced urine output or leg swelling — possible kidney involvement
• Difficulty swallowing or unexplained weight loss — requires endoscopy regardless of antacid use

🟡 Schedule an Appointment If:

• Taking any antacid daily for more than 14 days without medical advice
• On PPIs for more than 3 months without recent review
• Experiencing fatigue, tingling, or muscle cramps on long-term antacids
• Over 60 and on PPIs without annual nutrient monitoring
• Wanting to stop PPIs but symptoms return every time you try

🟢 General Rule:

No medication, prescription or over-the-counter, is completely risk-free. When used as directed, antacids are usually safe and effective. However, if you are taking medications like Prilosec or Nexium beyond the recommended 14-day course, there are some potential risks. Always use the lowest effective dose for the shortest necessary duration — and review annually with your doctor. University Hospitals

Frequently Asked Questions

What are the long-term side effects of taking antacids every day?

Daily antacid use — particularly PPIs — is associated with vitamin B12 deficiency, magnesium deficiency, calcium malabsorption, increased fracture risk, kidney disease, C. diff infection risk, gut microbiome disruption, and rebound acid hypersecretion when stopping. Classic antacids (Tums, Maalox) at recommended doses carry lower risk — but aluminum-containing antacids cause constipation and phosphate depletion with prolonged use.

Is it safe to take omeprazole every day for years?

Medical guidelines now emphasize using the lowest effective dose for the shortest necessary time. Long-term use may still be appropriate for some people, but it should be a conscious decision made with a healthcare provider. People with Barrett’s esophagus, severe erosive esophagitis, or Zollinger-Ellison syndrome have genuine long-term PPI indications. People using PPIs for mild occasional reflux are almost certainly using them beyond medical necessity. Ubie

Can antacids damage kidneys?

Studies have suggested a link between long-term PPI use and an increased risk of both acute interstitial nephritis and chronic kidney disease. While the absolute risk is relatively small, it’s a significant concern for individuals already at risk for kidney problems. Classic antacids containing aluminum or magnesium are specifically dangerous in people with existing kidney disease — these minerals accumulate when kidneys cannot excrete them. Wellri

Do antacids cause vitamin B12 deficiency?

Yes — with long-term use. Stomach acid separates B12 from food proteins. Suppressing acid prevents this separation — leaving B12 unabsorbed. The risk increases with duration of use and is highest after 2+ years. Annual B12 testing is recommended for anyone on long-term PPIs.

Can you become dependent on antacids?

Yes — specifically with PPIs. Long-term PPI use causes upregulation of acid-producing machinery. Stopping abruptly causes rebound acid hypersecretion — often more severe than original symptoms — creating apparent dependency. This is a physiological drug effect, not psychological addiction. Gradual tapering over 4–8 weeks prevents rebound in most patients.

Do antacids cause osteoporosis?

Long-term PPIs are associated with reduced bone density and increased fracture risk — through calcium malabsorption and possible direct effects on bone metabolism. The FDA requires fracture warnings on PPI labels. People on long-term PPIs should ensure adequate calcium and vitamin D intake and have periodic bone density assessment if over 50.

What happens when you stop taking antacids after long-term use?

Abrupt cessation after long-term PPI use causes rebound acid hypersecretion — significantly increased acid production lasting 2–4 weeks. Symptoms include heartburn worse than before treatment. This does not mean the medication is still needed — it is a withdrawal effect. Gradual step-down tapering prevents rebound in most patients.

Are H2 blockers safer than PPIs long-term?

Generally yes — H2 blockers (famotidine) produce less profound acid suppression than PPIs and carry lower long-term risk for nutrient deficiency, fracture, and kidney disease. For mild-to-moderate reflux, H2 blockers are the preferred long-term option when medication is genuinely required.

Can antacids cause magnesium deficiency?

Yes — with long-term PPI use. The FDA issued a 2011 safety warning requiring PPI labels to warn about hypomagnesemia after multiple reports of severely low magnesium levels in long-term PPI users. Hypomagnesemia from PPIs typically appears after 12+ months of use and can cause muscle cramps, arrhythmias, and seizures in severe cases.

Do antacids interact with other medications?

Yes — significantly. PPIs reduce the effectiveness of clopidogrel (a blood thinner used after heart attacks and stents) — a clinically important interaction. Antacids reduce absorption of thyroid medications, bisphosphonates, some antibiotics, and iron supplements. All antacids should be taken at least 2 hours apart from other medications unless specifically directed otherwise.

How do I know if I need antacids long-term?

Genuine long-term PPI indications include: severe erosive esophagitis confirmed on endoscopy, Barrett’s esophagus, Zollinger-Ellison syndrome, and documented peptic ulcer disease. Mild-to-moderate reflux symptoms in the absence of these conditions should first be managed with lifestyle modification and short-course treatment — not indefinite PPIs.

What is the safest antacid for long-term use?

Calcium carbonate antacids (Tums) at recommended doses are the safest for occasional use. For regular daily use, famotidine (H2 blocker) carries the lowest long-term risk profile among acid-suppressing medications. No antacid is completely risk-free with daily long-term use — lifestyle modification to address the underlying cause is always preferable to indefinite medication.

Can antacids cause C. diff infection?

Yes — stomach acid normally kills C. diff spores. Acid suppression allows these spores to survive and colonize the colon. Long-term PPI use is an established risk factor for C. diff infection — particularly in older adults, hospitalized patients, and people who have recently taken antibiotics. Severe or persistent diarrhea in a long-term PPI user requires immediate medical evaluation.

Should elderly people avoid long-term antacids?

Older adults are at higher risk from long-term antacid side effects — including fractures (already at risk for osteoporosis), B12 deficiency (absorption declines with age), C. diff infection (more severe in elderly), and drug interactions (more likely to be on multiple medications). Regular medication review and nutrient monitoring are essential for elderly people on long-term acid suppression.

Can I take antacids during pregnancy?

Classic antacids (calcium carbonate, magnesium hydroxide) are generally considered safe during pregnancy at recommended doses and are preferred over PPIs and H2 blockers for mild reflux. Various studies have recommended lifestyle modifications and antacid use as first choice among pregnant women, preserving PPIs for severe conditions of gastroesophageal reflux disease. Always discuss any medication use during pregnancy with your obstetrician. PubMed

---

Conclusion

Long-term antacid use — particularly with proton pump inhibitors — is one of the most clinically significant examples of medication overuse in modern medicine. PPIs are among the most prescribed medications worldwide, yet a substantial proportion of long-term users have no genuine ongoing medical indication for them.

The evidence is clear on three points:

What long-term antacid use does: It suppresses stomach acid beyond the acute therapeutic period — impairing nutrient absorption, disrupting gut microbiome, reducing infection defense, and potentially damaging kidney and bone health over years of use.

What the evidence establishes: Nutrient deficiencies (B12, magnesium, calcium), fracture risk, kidney disease, and C. diff infection are the most consistently documented long-term risks — supported by multiple large-scale studies and FDA safety warnings.

What patients and clinicians should do: Use the lowest effective dose for the shortest necessary duration. Review long-term antacid use annually. Monitor nutrients in anyone on PPIs beyond 12 months. Taper gradually — never stop abruptly. Address the underlying cause with lifestyle modification wherever possible.

Key Takeaways:

• PPIs beyond 14 days require medical justification — not just symptom persistence
• Annual B12, magnesium, and renal function monitoring is essential for long-term PPI users
• Rebound acid hypersecretion is real — always taper gradually with medical guidance
• Fracture risk requires calcium and vitamin D supplementation and periodic bone density assessment
• C. diff risk is highest when PPIs are combined with antibiotics — minimize concurrent use
• Drug interactions with clopidogrel, thyroid medications, and iron are clinically significant
• Many long-term PPI users can successfully discontinue with a structured tapering protocol and lifestyle changes
