Do you often have conditions like heartburn, or what the doctor calls "gastritis"? Sometimes, when these conditions become severe, or when it becomes difficult to eat or drink, you may remember that doctors recommend an injection into a vein. Famotidine is a very common injection used at such times. Today, let's talk briefly about this drug, what it does, and what things to be careful about.
What is Famotidine?
Simply put, famotidine is a medicine that reduces the amount of acid produced in your stomach. Our stomach acids are essential for digesting food. But when this acid becomes too much, conditions like gastritis, stomach ulcers, and heartburn occur.
So what this famotidine injection does is control the amount of acid that's being produced. It gives your stomach relief, if there are ulcers, they start to heal, and the inflammation decreases. It's also available as a pill, but the injection we're talking about today is usually only given in a hospital if the condition is a little more severe or if it's difficult to take pills.
Things you need to tell your doctor before taking this medicine
This is very important. It is essential that your doctor knows your complete health history before giving you this vaccine. Be sure to tell them about these things in particular.
- Kidney or liver disease: If you have any kidney or liver disease, you should tell your doctor. Because these two organs are responsible for filtering and removing drugs from the body. So if their function is impaired, the doctor may have to change the dose of the medication.
- Allergies: Tell your doctor if you have ever had an allergy to famotidine or other similar medications (e.g. Ranitidine). Also, tell your doctor if you have any allergies to any other medications, foods, or dyes.
- Pregnancy or expecting a baby: If you are pregnant or are expecting a baby soon, this is something you should tell your doctor.
- If you are a breastfeeding mother: If you are a breastfeeding mother, be sure to mention that as well.
It is very important for your own safety to talk to the doctor without hiding this information.
How to use this medicine and things you should not forget
Because this is an infusion into a vein, it is only given in a hospital or clinic. It is given to you by trained nursing staff. So this is not a medicine to take home or keep.
What if you take too much medicine? (Overdose)
This is given in a hospital setting, so the chances of this happening are very low. However, if you think you have taken too much of the medicine, inform the medical staff immediately. If you have taken too much of any other medicine at home, remember to call the National Poisons Information Centre at the Colombo National Hospital . Or go to the Emergency Treatment Unit (ETU) of the nearest hospital.
Interactions with other medications
Tell your doctor about all the medications you are taking. This includes vitamins, supplements, herbal remedies, and even herbal teas. Some medications can interact with famotidine. For example, some antifungal medications (e.g., Itraconazole, Ketoconazole) can interfere with its effects. So give your doctor a list of all the medications you are taking .
Things you should be careful about when taking medication
- Be careful with painkillers: If you have gastritis or stomach ulcers, avoid taking painkillers (NSAIDs) like aspirin and ibuprofen . These medications can make stomach inflammation and ulcers worse. Ask your doctor before taking any pain medication.
- Smoking and alcohol: Smoking and drinking alcohol increase stomach acid and damage the stomach lining. This can delay the healing of your wounds. So it is best to stay away from these things at all times, not just while taking this medicine.
- Vitamin B12: Long-term use of medications like famotidine can cause a decrease in vitamin B12 levels. Talk to your doctor about this. He or she can give you appropriate advice if necessary.
- Warning signs: This is very important. Be very aware of these signs.
If your stools are black, tarry , or if you vomit coffee grounds , it could be bleeding in your stomach or intestines. This is an emergency. If this happens , see a doctor or go to the emergency room (ETU) immediately!
