In this session, we will be discussing the consumer medication information for rabeprazole, trade name AciphexTM.

What it’s for & How to take

Rabeprazole decreases the amount of acid produced in your stomach. Rabeprazole is used to treat a severe form of heartburn known as gastroesophageal reflux disease (also known as GERD), stomach ulcers, and other conditions that involve an increased stomach acid.

Rabeprazole may help decrease symptoms such as heartburn, a persistent cough related to stomach acid, or a constant burning in your stomach.

Rabeprazole is usually taken once daily in the morning, with or without food. If you forget to take a dose, take it as soon as you remember. If it is near the time of your next dose, skip it and continue with your normal dose time. Do not take a double dose to make up the missed dose.

Rabeprazole should offer some relief from your symptoms the first day you take it. It may take up to a week for the full effect to be noticed. If you do not notice any relief within 7 days, call your doctor.

Continue taking this medication even after your symptoms have gone away. Rabeprazole is decreasing the acid and giving your stomach some time heal.

Usually, your doctor will have you take this medication for 4-8 weeks. Ask your doctor how long they want you to take this medication for and when they want to see you again. Sometimes your doctor may have you take this medication for a longer period of time.
