Prevacid (Lansoprazole) Buyer and Patient Handbook in Singapore
What is Prevacid?
Prevacid is a proton-pump inhibitor (PPI) that reduces stomach acid production. It is commonly prescribed for gastro-esophageal reflux disease (GERD), peptic ulcers, and Zollinger-Ellison Syndrome. The medication is approved by the Health Sciences Authority (HSA) of Singapore and is available as oral pill tablets.
Who Should Use Prevacid?
- Adults diagnosed with GERD, Erosive Esophagitis, or ulcer disease.
- Patients needing ulcer prevention while on non-steroidal anti-inflammatory drugs (NSAIDs).
- Individuals with confirmed hypersecretory conditions such as Zollinger-Ellison syndrome.
How Does It Work?
Prevacid blocks the H⁺/K⁺-ATPase enzyme (the “acid pump”) in the stomach lining, preventing the final step of acid secretion. By lowering gastric acidity, it allows damaged tissue to heal and reduces symptoms like heartburn and indigestion. It is not habit-forming, but long-term use should be monitored by a healthcare professional.
Why Choose Prevacid?
- Proven efficacy for healing erosive esophagitis within weeks.
- Once-daily dosing simplifies adherence.
- Generic lansoprazole offers the same therapeutic effect at a lower cost compared with brand-only options.
Dosage, Administration, Lifestyle and Dietary Recommendations
Recommended Dosage
- 15 mg tablet once daily for ulcer prevention.
- 30 mg tablet once daily for GERD, erosive esophagitis, or Zollinger-Ellison syndrome.
How to Take
- Swallow the tablet whole with a full glass of water.
- Take 30 minutes before the first meal of the day for optimal absorption.
Missed Dose
- Take the missed dose as soon as you remember if it is still the same day.
- If it is close to the next scheduled dose, skip the missed one and continue with your regular schedule.
Overdose
- If you suspect an overdose, seek immediate medical attention or contact the Singapore National Poison Centre (180-222-1111).
Special Populations
- Elderly: No dose adjustment required, but monitor renal function.
- Children: Not approved for use under 12 years in Singapore.
- Renal or hepatic impairment: Standard dose is usually adequate; consult a physician for individual assessment.
Lifestyle & Diet
- Avoid grapefruit juice within a few hours of taking the medication, as it may increase drug levels.
- Maintain a balanced diet; avoid large meals immediately before bedtime to reduce reflux.
Precautions and Warnings
- Use the lowest effective dose for the shortest duration needed.
- Long-term use (≥ 12 months) may increase the risk of vitamin B12 deficiency, bone fractures, and intestinal infections.
- Do not combine with other PPIs or H₂-blockers without professional advice.

Frequently Asked Questions
How quickly will I feel relief after starting Prevacid?
Most patients experience symptom relief within 3-5 days, though full ulcer healing may take 4-8 weeks.
Can I take Prevacid with antacids?
Yes, but separate intake by at least 2 hours to avoid reduced absorption of the PPI.
Is it safe to use Prevacid while pregnant?
Prevacid is classified as Pregnancy Category C in Singapore; use only if the potential benefit outweighs the risk and after discussing with a healthcare professional.
Will drinking coffee interfere with Prevacid?
Moderate coffee consumption does not affect efficacy, but excessive caffeine may exacerbate reflux symptoms.
Can I stop Prevacid abruptly?
Abrupt discontinuation can lead to rebound acid hypersecretion. Taper the dose under medical guidance if long-term therapy is planned.
Does Prevacid interact with alcohol?
Alcohol does not directly affect drug metabolism, but excessive intake may worsen reflux and ulcer symptoms.
What should I do if I miss a dose for several days?
Restart at the usual dose after a short break, but consult a healthcare provider if symptoms persist.
Is long-term use of Prevacid associated with any nutritional deficiencies?
Prolonged therapy may reduce absorption of vitamin B12 and magnesium; periodic testing is advisable.

Reviews
Started on 30mg for gastritis. Works FAST, acid reflux is basically gone. The downside? My stomach feels like a heavy wet rock all the time. Also, this insane metallic taste that won't quit, especially in the mornings. Trying to take it only every other day now. Hope that works.
Been on 15mg of lansoprazole for over three years now due to GERD. The trick is to take it 45 mins before breakfast, not just 30. And never, ever chase it with coffee. If I cheat and have a spicy meal, I feel it the next morning, but it's manageable. Energy levels feel lower overall, but I'll take it over the burning chest.
I call these the "Brain Fog Pills." Sure, the constant throat burn disappeared within a week of the 30mg dose. But the confusion, man. I forget words mid-sentence. My ophthalmologist says it might be related to nutrient absorption. I supplement B12 and Magnesium now, which helps a bit. Mandatory dosing hack: Take Magnesium Citrate at night, hours away from the pill.
Just started 15mg a week ago for LPR. The coughing is gone, fantastic. But I woke up with the worst leg cramp ever yesterday. Doctor didn't warn me about mineral depletion. Taking Calcium Gummies now. Also, my appetite is weirdly suppressed. Feel full after three bites. Still figuring out if this trade-off is worth the lack of voice hoarseness.
It works fine but weaning off is hell. I've been trying to taper down from 30mg to every-other-day dosing for three months. The acid rebound is brutal, like a fire hose turning back on. The hack I learned is to introduce H2 blockers late in the day (like Famotidine) during the taper phase. Lanso in the morning, H2 at 8 PM. It's the only way to minimize the fiery reflux.
I'm a long-term user, five years strong, 30mg. Keeps the Barrett's esophagus controlled, so I can't complain much. My only issue is constant diarrhea/soft stool. It's just the new normal. I counterbalance it by adding more soluble fiber (oats, psyllium). If you miss the morning dose, you are screwed for the day. Consistency is the key to minimizing side effects.
This fixed my esophageal spasms (great relief) but gave me crushing anxiety. It feels like my chest pressure just migrated up to my head. I tried stopping, and the spasms came back instantly. So I'm stuck. My current routine is the 15mg pill early, followed by a massive glass of water, and then strictly no food or drink for 60 minutes. Helps slightly with the mental side effects.
Started on 30mg. The heartburn stopped instantly, fantastic. But I got these horrible musculoskeletal aches, especially in my lower back, after the second week. It felt like I aged 30 years overnight. Dropped down to 15mg and the pain mostly subsided, but now I get slight breakthrough acid if I eat pizza. It's a constant balance game.
