What is Prevacid?

Prevacid is a medication that decreases the amount of acid that is produced in your stomach. In the group of medications called proton pump inhibitors, or PPIs, Prevacid helps to prevent and treat intestinal ulcers, erosive esophagitis and hypersecretory conditions such as Zollinger-Ellison syndrome. Prevacid is also prescribed for short-term treatment (up to 8 weeks) for healing and symptom relief of an active benign gastric ulcer.

Prevacid may also be used for conditions not stated in this medication guide.

Key Facts About Prevacid

Prevacid is part of a group of drugs called proton pump inhibitors, or PPIs. Prevacid can help you by decreasing the amount of acid produced in your stomach.

Your doctor may have prescribed Prevacid to help treat your symptoms from conditions involving excess stomach acids, like Zollinger-Ellison syndrome.

Prevacid may also be given alongside antibiotics to treat certain conditions. It is important that you take all of the medications your doctor has prescribed.

Prevacid should not be used for an immediate relief of your heartburn symptoms.

Heartburn may be confused with initial symptoms of a heart attack. You should seek emergency medical assistance if you experience chest pain or a heavy feeling, nausea, sweating, pain spreading to your arm or shoulder, or a general feeling of being ill while taking Prevacid.

If you are being treated with both Prevacid and sucralfate (Carafate) you should avoid taking these medications at the same time. Sucralfate can make it harder for your body to absorb Prevacid. You should wait at least 30 minutes after taking this Prevacid before you take sucralfate.

If you take a proton pump inhibitor like Prevacid you may have an increased risk of bone fractures in your hips, wrists, or spine. This effect has occurred in people who have either taken this medication for a long time and at high doses, or who are older than age 50. It is not known if Prevacid is the cause of this increased risk of fractures.

Prevacid is in FDA Category B. We do not know if Prevacid can harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant if you are taking Prevacid.

Directions for Taking Prevacid

You should take Prevacid for the entire length of time your doctor has prescribed you to take it, even if your symptoms improve before you have finished your prescription. Sometimes your symptoms may improve but your condition has not yet been fully treated. You should call your doctor if your symptoms do not improve or if you experience a worsening of your symptoms while taking this medicine.

You should take each dose of Prevacid before eating, preferably in the morning before you eat breakfast.

Prevacid 24 HR should be taken only one time every 24 hours, for 14 days. You may not notice an improvement in your symptoms for up to 4 full days while taking Prevacid. Do not stop taking this medication and do not take more than one tablet every 24 hours.

You should allow at least 4 months to pass before you start another 14-day treatment with Prevacid. Tell your doctor if you experience symptoms before the 4 month time period has passed, and if you feel you need additional treatment.

You may also take the Prevacid delayed-release capsule and open it to sprinkle the medication into a spoonful of applesauce or pudding to make it easier for you to swallow. You must swallow this mixture immediately, without chewing it. You can alternatively dissolve the contents inside the Prevacid capsule into 2 ounces of juice, such as apple, orange or tomato. Do not save any unused mixture for later use, and be sure to discard the empty capsule.

If you are being treated with the Prevacid oral suspension (liquid) shake it well before taking it. Be sure to use a special dose-measuring spoon or medicine cup, and not a regular table spoon to take Prevacid. If you do not have a dose-measuring device, your pharmacist can give one to you.

If you are taking the oral granules of Prevacid you can put them in 2 tablespoons of water. You must only use only water when mixing Prevacid oral granules. Stir this mixture well and drink it all immediately. You can add a bit more water to your glass, swish it a little and drink it to be sure that you got the entire dose. You should not save the mixture for later use.
