Pepcid AC How to Take

Pepcid AC (Famotidine) belongs to a class of medications called H2 antagonists. It is used to treat stomach and duodenal (intestinal) ulcers, GERD (Gastroesophageal reflux disease) (GERD), and conditions where too much stomach acid is secreted, such as Zollinger-Ellison syndrome. It is also used to prevent duodenal ulcers and prevent GERD symptoms from coming back. It works by reducing the amount of acid secreted by the stomach.

The over-the-counter form of Pepcid AC (Famotidine) is used to treat conditions where a reduction of stomach acid is needed, such as acid indigestion, heartburn, or sour or upset stomach. It can also be used to prevent these symptoms when they are associated with eating food or drinking beverages, including nighttime symptoms.

Pepcid AC (Famotidine) may be available under multiple brand names and/or in several different forms. Any specific brand name of Pepcid AC (Famotidine) may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of Pepcid AC (Famotidine) may not be used for all of the conditions discussed here.

Your doctor may have suggested Pepcid AC (Famotidine) for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are using Pepcid AC (Famotidine), speak to your doctor. Do not stop using Pepcid AC (Famotidine) without consulting your doctor.

Do not give Pepcid AC (Famotidine) to anyone else, even if they have the same symptoms as you do. It can be harmful for people to use Pepcid AC (Famotidine) if their doctor has not prescribed it.

  • stop taking one of the medications,
  • change one of the medications to another,
  • change how you are taking one or both of the medications, or

An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.

Medications other than those listed above may interact with Pepcid AC (Famotidine). Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, the Nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them.

Pepcid AC Warnings

Before you begin using a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use Pepcid AC (Famotidine).

Kidney Disease: Pepcid AC (Famotidine) is removed from the body mostly by the kidneys. Kidney disease or reduced kidney function may cause Pepcid AC (Famotidine) to build up in the body, causing side effects. If you have reduced kidney function or kidney disease, discuss with your doctor how Pepcid AC (Famotidine) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Pepcid AC (Famotidine), and whether any special monitoring is needed. Lower doses or longer intervals between doses may be needed.

Severe stomach problems: Although common, heartburn and acid indigestion can sometimes be a warning sign for more serious stomach problems. If you are over the age of 40 and are experiencing heartburn for the first time, you should check with your health care professional before starting Pepcid AC (Famotidine). If you have recurrent vomiting, difficulty swallowing, blood in the stool, significant unintentional weight loss, fatigue (Anemia), or are coughing up blood, check with your doctor right away. If you have heartburn that continues, worsens, or returns after using Pepcid AC (Famotidine) continuously for 2 weeks, check with your doctor. If you frequently need to use Pepcid AC (Famotidine) for heartburn for 14 days in a row, you should see your doctor.

Pregnancy: Pepcid AC (Famotidine) should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking Pepcid AC (Famotidine), contact your doctor immediately.

Breast-feeding: Pepcid AC (Famotidine) passes into breast milk. If you are a breast-feeding mother and are taking Pepcid AC (Famotidine), it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
