Prevacid OTC (Lansoprazole)

Description

Prevacid (Lansoprazole) is a proton pump inhibitor (PPI) used to treat conditions involving excess stomach acid. It works by decreasing the amount of acid produced in the stomach, providing relief from symptoms and allowing healing of the affected tissues. Common uses include managing duodenal and gastric ulcers, gastroesophageal reflux disease (GERD), erosive esophagitis, and conditions like Zollinger-Ellison syndrome. The medication is available in both capsule and orally disintegrating tablet forms.

Directions

Prevacid OTC is a medication taken by mouth, usually in the form of a 15 mg capsule once daily. It’s best to take it before eating, preferably in the morning. If your symptoms continue after taking it, you should talk to a healthcare provider.

Make sure to swallow a Prevacid OTC dose whole with water and don’t crush or chew the tablet. Taking it at the same time every day may help it work better. When using Prevacid OTC, you should limit your treatment to 14 days in a row unless your doctor advises otherwise.

Ingredients

The active ingredient in Prevacid OTC is Lansoprazole.

Side Effects

Prevacid OTC may cause common side effects such as diarrhea, stomach pain, nausea, and constipation. These symptoms are usually mild and often resolve as your body adjusts to the medication. If these effects persist or worsen, consult a healthcare provider for guidance.

Serious side effects of Prevacid OTC, while rare, include severe skin reactions with symptoms like blistering, peeling, or bleeding, accompanied by fever, chills, or body aches. Low magnesium or vitamin B12 levels may also occur with prolonged use, leading to symptoms like dizziness, irregular heartbeat, or muscle weakness. In addition, long-term use may increase the risk of stomach growths called fundic gland polyps. If you notice serious symptoms, stop taking Prevacid OTC and seek immediate medical attention.
