Prevacid (Lansoprazole) Buyer and Patient Handbook in South Africa

What is Prevacid?

Prevacid is a proton-pump inhibitor (PPI) used to reduce stomach acid. It treats conditions such as gastro-oesophageal reflux disease (GERD), peptic ulcers and Zollinger-Ellison Syndrome. The medication is supplied as oral pill tablets and carries FDA, EMA and South African Health Products Regulatory Authority (SAHPRA) approval.

Who Should Use Prevacid?

• Adults experiencing frequent heartburn or acid reflux
• Patients diagnosed with gastric or duodenal ulcers
• Individuals with confirmed excess stomach acid production (e.g., Zollinger-Ellison syndrome)
• Those who need ulcer prevention while taking non-steroidal anti-inflammatory drugs (NSAIDs)

How Does It Work?

Prevacid blocks the hydrogen-potassium ATPase enzyme in the stomach lining, stopping the final step of acid secretion. Think of it as turning off the faucet that constantly drips acid into the stomach. The effect lasts up to 24 hours, providing sustained relief.

Why Choose Prevacid?

The branded formulation offers consistent bioavailability and proven stability across the 15 mg and 30 mg strengths. Generic lansoprazole tablets are available and meet strict bio-equivalence standards, offering a cost-effective alternative. Off-label uses (e.g., as part of H. pylori eradication regimens) should only be considered after professional consultation.

Dosage, Administration, Lifestyle and Dietary Recommendations

Recommended Dosage

• 15 mg: Once daily for mild-to-moderate GERD or ulcer prevention.
• 30 mg: Once daily for severe GERD, active ulcer treatment or confirmed hyper-acid conditions.

How to Take

Swallow the tablet whole with a full glass of water, preferably before a meal (ideally 30 minutes prior). Do not crush, chew, or split the tablet, as this may affect absorption.

Missed Dose

If you miss a dose, take it as soon as you remember provided it is at least 6 hours before the next scheduled dose. Otherwise, skip the missed tablet and resume your regular schedule; do not double-dose.

Overdose

In case of suspected overdose, seek immediate medical attention or contact the local poison information centre (010 711 1111). Symptoms may include severe dizziness, rapid heartbeat or fainting.

Special Populations

• Elderly: Start with the lower 15 mg dose and monitor for side-effects.
• Renal impairment: No dose adjustment needed for mild to moderate reduction; severe impairment warrants physician review.
• Pregnancy & breastfeeding: Use only if clearly needed; limited data suggest low risk but discuss with a health-care professional.

Lifestyle & Diet

Avoid grapefruit juice within two hours of taking Prevacid, as it can increase drug levels. Limit alcohol consumption, which may worsen stomach irritation. Maintain an upright position for at least 30 minutes after dosing to aid gastric emptying.

Precautions and Warnings

Prevacid should be used with caution in patients with known liver disease, Osteoporosis, or a history of Clostridioides difficile Infection. Long-term use (beyond 12 months) may increase the risk of fractures, vitamin B12 deficiency and low magnesium levels. Discontinue and seek advice if you develop persistent nausea, vomiting, or unexplained abdominal Pain.

Frequently Asked Questions

How long does it take for Prevacid to relieve heartburn?

Most people feel relief within 1 hour, with maximum effect after 3-4 hours.

Can I take Prevacid with coffee?

Is it safe to use Prevacid daily for months?

Short-term use (up to 8 weeks) is generally safe. For longer periods, regular monitoring of bone density and vitamin B12 levels is advisable.

Will Prevacid interact with my HIV medication?

Certain protease inhibitors can affect PPI metabolism. Review your specific regimen with a health-care professional.

Can I stop taking Prevacid abruptly?

Yes, abrupt discontinuation is usually fine, but some patients experience rebound acid hypersecretion. If this occurs, taper the dose under guidance.

Does alcohol affect the action of Prevacid?

Alcohol can irritate the stomach lining and may diminish symptom relief, so moderate consumption is recommended.
