Table of contents:

Prevacid DR used to treat and prevent stomach and intestinal ulcers and to manage symptoms caused by gastroesophageal reflux disease (GERD). It helps to relieve symptoms of conditions such as stomach and intestinal ulcers, erosive esophagitis, and other conditions associated with excess stomach acid.

Prevacid contains an active ingredient called lansoprazole. Lansoprazole belongs to a group of drugs called proton pump inhibitors (PPI). They work by reducing the amount of acid produced in the stomach. It works by blocking the production of acid in the stomach by inhibiting the activity of the proton pumps that produce acid in the stomach lining.

Use and Dosage

Prevacid, is available as DR capsules that should be ingested orally according to your doctor's instructions, typically once daily before a meal. If you are administering it to yourself, make sure to adhere to all directions provided in the package.

The dosage and duration of treatment for the medication is determined by your medical condition and your response to the treatment. The dosage for children varies in accordance with their age and weight. Please do not take the medication more frequently than instructed or increase the dosage. If you have any questions, never hesitate to ask your pharmacist or doctor.

Do not chew or break the capsules. Instead, swallow them whole. If you encounter difficulty swallowing the capsules, you may open them, sprinkle the contents onto a spoonful of soft food (such as yogurt, cottage cheese, or applesauce), and swallow the mixture immediately without chewing it. Alternatively, you can mix the contents of the capsule with a small amount of juice (about 2 ounces or 60 milliliters), stir, and drink it right away without chewing it. Rinse the glass with additional juice to ensure that you consume the whole dosage, and never prepare the combination in advance for later use as this may cause drug damage.

To benefit from Lansoprazole capsules, you need to use it consistently. Take the medication daily at the same time each day to help you remember. Please continue to use Lansoprazole capsules for the prescribed duration of treatment even if you start feeling better. If you are using the over-the-counter product for self-treatment, do not continue for over 14 days without the direction of your doctor.
