Prevacid and Alcohol

Alcohol and other foods such as caffeine increase the amount of acid the stomach produces so drinking alcohol may lessen the effect of Prevacid.

In addition, consuming alcohol may increase the risk for digestive side effects like constipation, stomach pain, nausea, diarrhea, and possible vomiting.

Prevacid is marketed under the brand names Prevacid, Prevacid 24hour, and Prevacid Solutab.

Lansoprazole is also available under the name First-Lansoprazole.

Regular Prevacid capsules are available in 15 and 30 milligrams (mg). Prevacid 24hour and Prevacid Solutab are delayed release drugs that also come in both 15 and 30 mg.

Prevacid SoluTab dissolves under the tongue. First-Lansoprazole is a powder that is made into an oral suspension.

Prevacid 24hour should be taken only once every 24 hours for 14 days. It may take up to four days for the full effect.

Do not take more than one tablet every 24 hours.

If you are taking the over-the-counter medication, stop taking after 14 days and call your doctor if there has been no change in your condition.

Allow at least four months before starting another 14-day treatment with Prevacid 24hour.

Call your doctor if you have additional symptoms and need treatment before the four months have passed.

Consult a doctor before giving Prevacid to a child. Children under age 1 should not take this drug.

Missed Dose of Prevacid

Go ahead and take your missed medication unless you are near the time of your next scheduled dose.

If that’s the case, just take your regularly scheduled dose and return to your normal schedule. Do not double your dose.

Prevacid Overdose

Symptoms of Prevacid overdose include difficulty breathing, breaking out in hives, and swelling of the face, lips, tongue, or mouth.

Seek emergency medical help if you experience an overdose reaction from Prevacid.
