Pharmacist tips for Famotidine (Pepcid AC)

pharmacist

  • Famotidine (Pepcid AC) can be taken with or without food. If it's upsetting your stomach, try taking it with food to help.

    • If famotidine (Pepcid AC) alone is not providing you with enough heartburn relief, ask your provider about taking an antacid or PPI with famotidine (Pepcid AC) for better relief.

      • Famotidine (Pepcid AC) can interact with a lot of medications, especially those that need an acidic environment in your stomach for better absorption into your body. Make sure to tell you provider about all of the medications you're taking before starting famotidine (Pepcid AC). Don't start any new medications while taking famotidine (Pepcid AC) without talking to your provider or pharmacist first. They will make sure all of your medications are safe for you.

        More tips for the oral suspension (liquid) only:

        • Shake the bottle well for 5 to 10 seconds before each dose. Make sure to only use a medication dose cup or syringe from the pharmacy to measure out your dose. Don't use household spoons because they aren't accurate and might cause you to take the wrong dose.

          • Store the suspension at room temperature in the original bottle it came in from the pharmacy for up to 30 days. After 30 days, throw away the medication bottle, even if there's still some medication left.

            More tips for over-the-counter famotidine (Pepcid AC) only:

            • Don't use famotidine (Pepcid AC) with other acid-lowering therapy unless your provider specifically said it was safe to do so.

              • Ask your provider if it's safe for you to take famotidine (Pepcid AC) if you: 1) had heartburn for over 3 months; 2) have heartburn with lightheadedness, sweating, or dizziness; 3) have chest pain or shoulder pain with shortness of breath, sweating, pain spreading to arms, neck, or shoulders or lightheadedness; 4) frequent chest pain; 5) frequent wheezing with heartburn; 6) unexplained weight loss; 7) nausea or vomiting; 8) stomach pain; 9) kidney problems; 10) have trouble or pain swallowing food; 11) are vomiting with blood; 12) have bloody or black stools. These might be signs of a more serious problem that might require different treatment.

                • Stop using famotidine (Pepcid AC) if your heartburn continues or worsens or you feel you need to take famotidine (Pepcid AC) for more than 14 days.

                  faqs

                  Frequently asked questions about Famotidine (Pepcid AC)

                  Is famotidine (Pepcid AC) a first-choice treatment option for heartburn?
                  Famotidine (Pepcid AC) is one of the commonly prescribed treatment options for heartburn, but it might not be the best choice depending on how severe your condition is. The 2022 heartburn treatment guidelines recommends another class of heartburn medications called proton pump inhibitors (PPIs) over famotidine (Pepcid AC) for people with erosive esophagitis. This is because studies show that people who take PPIs have a faster healing rate and more complete heartburn relief compared to people who take famotidine (Pepcid AC). But, H2 antagonists are still one of the backbone treatment options for heartburn because they've been shown to work well in several studies. Your provider will decide if famotidine (Pepcid AC) is right for you based on your symptoms and cause(s) of heartburn. Read this article for learn more about the different medication options for heartburn.
                  What is the difference between Zantac 75, Zantac 150, Zantac 360, and Pepcid?
                  Zantac 75 and Zantac 150 were brands of ranitidine, an H2-blocker similar to famotidine (Pepcid AC). Ranitidine was removed from the market in April 2020 by the FDA. This happened because a long investigation showed there were detectable levels of a potential cancer-causing chemical (called nitrosamines) in ranitidine (Zantac) products. As a result of the immediate removal of all ranitidine (Zantac) products, the manufacturer of ranitidine (Zantac) released [Zantac 360] into the market, which contains famotidine (Pepcid AC) instead of ranitidine. There are no clear differences between Pepcid and Zantac 360 - both are brand names of famotidine.
                  Can I take famotidine (Pepcid AC) with omeprazole (Prilosec)?
                  Talk with your provider if you think famotidine (Pepcid AC) alone isn't enough for your heartburn symptoms. Omeprazole (Prilosec) is a proton pump inhibitor (PPI), another class of medication that can help treat heartburn symptoms. Famotidine (Pepcid AC) and omeprazole (Prilosec) aren't typically taken together. But there are certain situations where your provider might recommend adding famotidine (Pepcid AC) to omeprazole (Prilosec). For example, if your heartburn symptoms aren't relieved by omeprazole (Prilosec) and get worse at night, your provider might recommend for you to take famotidine (Pepcid AC) at bedtime, as needed.
                  Is famotidine (Pepcid AC) safe if I'm pregnant?
                  Based on available data about human pregnancy, there isn't a clear link between famotidine (Pepcid AC) and birth defects or pregnancy-related problems, such as early labor. American Academy of Family Physicians (AAFP) considers famotidine (Pepcid AC) a probably safe option for pregnant females, but more data is needed. If you're pregnant, discuss with your provider about the risks and benefits of taking famotidine (Pepcid AC) before using to make sure it's safe for you and your unborn baby.
                  Is famotidine (Pepcid AC) safe if I'm breastfeeding?
                  Yes, famotidine (Pepcid AC) is generally considered safe during breastfeeding. While some of the medication does get into breastmilk, the amount is low and wouldn't be expected to cause any harm to your baby. But, to be safe, always discuss with your provider about the risks and benefits of taking famotidine (Pepcid AC) while breastfeeding.

                  What are the risks and warnings for Famotidine (Pepcid AC)?

                  Famotidine (Pepcid AC) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

                  risk-warning

                  Agitation, confusion, and other brain-related side effects

                  • Risk factors: Kidney problems

                    Famotidine (Pepcid AC) can cause certain brain-related side effects, such as confusion, delirium, hallucinations (seeing things that aren't real), agitation, seizures, and weakness. The risk is higher in people with kidney problems because it's more difficult for their kidneys to metabolize (break down) famotidine (Pepcid AC), which raises the blood levels of famotidine (Pepcid AC) and can cause side effects. If you've kidney problems, your provider might lower your dose of famotidine (Pepcid AC). Talk to your provider if you have kidney problems and are interested in taking famotidine (Pepcid AC).

                    risk-warning

                    Possible risk of cancer

                    Rarely, heartburn can be warning signs of a more serious stomach problem or cancer. Sometimes, taking heartburn medications, like famotidine (Pepcid AC), can mask these warning signs. If your heartburn symptoms don't go away after you've completed treatment with famotidine (Pepcid AC), contact your provider. You might need to undergo testing to see if you have a more serious problem like stomach cancer.
