Prevacid: Effective Prescription Relief for Chronic Heartburn
Prevacid
Prevacid (lansoprazole) is a proton pump inhibitor (PPI) prescribed for the management of conditions related to excess stomach acid. It works by decreasing the amount of acid produced in the stomach, providing long-lasting relief and promoting healing of acid-related damage. This medication is commonly used to treat gastroesophageal reflux disease (GERD), erosive esophagitis, and stomach ulcers. Available in delayed-release capsules and orally disintegrating tablets, it offers flexible dosing options under medical supervision. Always follow your healthcare provider’s instructions for safe and effective use.
Features
- Active ingredient: lansoprazole
- Formulations: delayed-release capsules (15 mg, 30 mg) and orally disintegrating tablets
- Mechanism: proton pump inhibitor (PPI)
- Onset of action: within 1–3 hours; full effect may take up to 4 days
- Duration: acid suppression lasts up to 24 hours or longer
- Prescription-only status in most regions
Benefits
- Provides sustained relief from frequent heartburn and acid regurgitation
- Promotes healing of erosive esophagitis and reduces risk of recurrence
- Helps prevent stomach ulcers caused by NSAIDs or H. pylori infection
- Reduces symptoms of GERD, improving overall quality of life
- Flexible administration options, including options for those who have difficulty swallowing pills
- Long-acting acid control allows for once-daily dosing in many cases
Common use
Prevacid is indicated for the short-term treatment (typically 4–8 weeks) of active duodenal ulcers, active benign gastric ulcers, GERD, and erosive esophagitis. It is also used for maintaining healing of erosive esophagitis and for hypersecretory conditions, including Zollinger-Ellison syndrome. In combination with antibiotics, it is employed for the eradication of Helicobacter pylori to reduce the risk of duodenal ulcer recurrence.
Dosage and direction
The typical adult dosage for healing erosive esophagitis is 30 mg once daily for up to 8 weeks. For maintenance therapy, 15 mg once daily is often prescribed. For GERD, 15–30 mg once daily is common. Prevacid should be taken before a meal, preferably in the morning. Capsules must be swallowed whole; do not crush, chew, or split. For patients who have difficulty swallowing, the capsule may be opened and sprinkled on a tablespoon of applesauce, yogurt, or similar soft food, and swallowed immediately without chewing. Orally disintegrating tablets should be placed on the tongue and allowed to disintegrate, then swallowed with or without water.
Precautions
- Long-term use (beyond one year) may be associated with an increased risk of fractures of the hip, wrist, or spine.
- May cause low magnesium levels (hypomagnesemia), especially with prolonged use; symptoms include muscle spasms, irregular heartbeat, or seizures.
- Not intended for immediate relief of heartburn; may take 1–4 days for full effect.
- Use with caution in patients with liver disease; dosage adjustment may be necessary.
- May increase risk of Clostridium difficile-associated diarrhea.
- Avoid use in patients with suspected gastric malignancy, as symptomatic response to lansoprazole does not preclude the presence of gastric cancer.
Contraindications
Prevacid is contraindicated in patients with known hypersensitivity to lansoprazole or any component of its formulation. It should not be used in patients taking rilpivirine-containing products due to the potential for reduced antiviral efficacy. Concomitant use with atazanavir or nelfinavir is not recommended, as lansoprazole may substantially decrease their plasma concentrations.
Possible side effect
Common side effects may include headache, diarrhea, abdominal pain, nausea, and constipation. Less frequently, dizziness, rash, or elevated liver enzymes may occur. Serious side effects, though rare, can include severe diarrhea, kidney problems (acute interstitial nephritis), vitamin B12 deficiency with long-term use, lupus erythematosus, or low magnesium levels. Contact your healthcare provider if you experience persistent or worsening symptoms.
Drug interaction
Lansoprazole may interact with drugs whose absorption is pH-dependent, such as ketoconazole, iron salts, and digoxin, potentially reducing their efficacy. It may increase the serum levels of methotrexate. Concomitant use with warfarin may require monitoring of INR. Lansoprazole can reduce the antiviral activity of atazanavir, nelfinavir, and rilpivirine. It may also interact with tacrolimus, clopidogrel, and St. John’s wort. Always inform your healthcare provider of all medications you are taking.
Missed dose
If you miss a dose of Prevacid, take it as soon as you remember, unless it is almost time for your next dose. In that case, skip the missed dose and resume your regular dosing schedule. Do not double the dose to make up for a missed one.
Overdose
There is limited experience with lansoprazole overdose. Reported manifestations are consistent with the known effects of the drug, such as drowsiness, blurred vision, tachycardia, nausea, diaphoresis, flushing, headache, and dry mouth. Specific recommendations for treatment are not established; provide symptomatic and supportive care. In case of suspected overdose, contact a poison control center or seek immediate medical attention.
Storage
Store Prevacid at room temperature (20–25°C or 68–77°F), in a dry place, away from light and moisture. Keep the container tightly closed. Do not store in the bathroom or near sinks. Keep out of reach of children and pets. Do not use beyond the expiration date printed on the packaging.

Reviews
(Note: Fictional examples based on common patient feedback patterns.)
- “After years of struggling with GERD, my gastroenterologist prescribed Prevacid. Within a week, my nighttime heartburn and regurgitation improved dramatically. I’ve been on maintenance therapy for six months with no significant side effects.”
- “I used Prevacid for H. pylori eradication along with antibiotics. The triple therapy was tough, but it successfully cleared the infection. My stomach ulcer healed, and I haven’t had a recurrence.”
- “Effective for my acid reflux, though I did experience some mild constipation initially. My doctor recommended increasing fiber and water intake, which helped. Overall, a reliable medication when used as directed.”
- “I’ve been on Prevacid for over a year for Barrett’s esophagus. Regular endoscopies show maintained healing. I get my magnesium and B12 levels checked periodically, and so far, so good.”
- “The orally disintegrating tablet is a game-changer for me since I have trouble swallowing pills. It works just as well as the capsule and doesn’t leave a bad taste.”
