What is this medicine called Famotidine?

Simply put, Famotidine is a medicine that reduces the amount of acid produced in your stomach. This helps control your stomach inflammation and acidity. Doctors usually prescribe this medicine for the following conditions:

  • Heartburn: Burning sensation in the chest after eating.
  • Stomach ulcers: Heal ulcers inside the stomach and prevent new ones from forming.
  • Reflux disease: Discomfort caused by stomach acid coming back up into the throat.
  • Other medical conditions that cause excess stomach acid production.

In Sri Lanka, this medicine may come under different brand names such as Pepcid and Zantac 360. But they all contain the same active ingredient, Famotidine.

Things you need to tell your doctor before taking this medicine

Although famotidine is generally a safe medication, there are a few things you should tell your doctor before using it, as it may not be compatible with certain health conditions.

Things to tell your doctor
Health status Description
Kidney disease If you have any kidney-related condition.
Liver disease If you have liver problems.
Difficulty swallowing If you have difficulty swallowing food or medicine.
Allergies If you have allergies to famotidine or other medicines or foods.
Pregnancy or planning to have it If you are pregnant or expecting a baby.
Being a breastfeeding mother If you are a breastfeeding mother.

How should I use the medicine?

Take this medicine with a glass of water. It is very important to take it exactly as the doctor tells you, in the amount prescribed.

  • If it's once a day: If your doctor tells you to take this medicine once a day, it's best to take it before going to bed at night .
  • Take it on time: Try to take your medicine at the same time every day if possible. Never take more than the doctor tells you to.

What if you take too much medicine? (Overdosage)

Imagine that you have accidentally taken too much of this medicine. If this happens, do not panic. Immediately call the National Poisons Information Centre at the Colombo National Hospital . Or go to the Emergency Treatment Unit (ETU) of the nearest hospital as soon as possible.

Remember, this medicine has been prescribed for you only. Do not share this medicine with a friend or family member, even if they have the same symptoms as you.

If you forget to take a dose, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and take your next dose at the scheduled time. Do not take a double dose for any reason.

Things to consider when taking medication

There are several things you should pay attention to when using this medicine.

  • Be careful with painkillers:Do not use anti-inflammatory medications like Aspirin and Ibuprofen (known to many as Brufen) during this time, as these medications can further irritate the stomach lining and worsen your condition.
  • Smoking and alcohol: Smoking and drinking alcohol are not good for the stomach. Stay away from these things as much as possible while taking Famotidine. These can delay the healing of stomach ulcers.
  • Vitamin B12: There is a small chance that your body's vitamin B12 levels may decrease when you use Famotidine for a long time. So talk to your doctor about the foods and vitamins you are taking.
