Sometimes, severe diarrhea can occur that does not respond to regular treatment and can persist. This can happen because the good bacteria in the gut are killed and bad bacteria grow, especially after using other antibiotics. So, a special medicine that doctors prescribe to control such specific bacterial infections is called fidaxomicin. Let's talk about this in detail.
What is Fidaxomicin?
Simply put, Fidaxomicin is an antibiotic. To be precise, it belongs to a class of drugs called ``macrolide antibiotics.'' What's special about it is that it targets only a few specific types of bacterial infections that occur in our intestines.
This medicine is often used to treat severe diarrhea caused by the bacteria Clostridium difficile. It is commonly found in the market under the brand name DIFICID.
Important: This medicine is only used to treat bacterial infections. It will not cure colds, flu, or other viral infections . Therefore, never use this medicine without a doctor's prescription.
Things you need to tell your doctor before taking this medicine
It is important that your doctor is aware of these facts before prescribing fidaxomicin to you. Therefore, if you have any of the following conditions, be sure to tell your doctor.
- If you have had an allergic reaction to fidaxomicin or other similar macrolide antibiotics (for example, azithromycin, clarithromycin, erythromycin).
- If you are allergic to any other medicine, food, coloring, or preservative.
- If you are pregnant or trying to get pregnant.
- If you are a breastfeeding mother.
Based on this information, it will be easier for the doctor to decide whether this medicine is right for you or not.
The medicine should be used in the right way.
This medicine usually comes in the form of a liquid (oral suspension), so be careful when using it.
- Shake the bottle well before use.
- Use only the special syringe, cup, or dropper provided by the pharmacy to measure the medicine. Home-made teaspoons and tablespoons can cause inaccurate measurements.
- This medicine can be taken before or after meals. If you experience stomach upset, it is best to take it with food.
- Take the exact dose, at the exact time prescribed by the doctor.
- The most important thing is to take this medicine for the full number of days prescribed by your doctor, even if you feel better. Do not stop taking it for any reason. If you do, the infection may come back.
If you give this medicine to children...
Even for children over 6 months of age, doctors may prescribe this medicine under certain conditions. However, it is up to your pediatrician to decide. Follow his or her instructions carefully when giving the medicine to your child.
What to do if you overdose?
