What kind of medicine is Tedizolid really?

Simply put, Tedizolid is an antibiotic. That is, a drug used to treat and prevent bacterial infections. It belongs to a class of antibiotics called Oxazolidinone''.

Think about it, some types of bacteria are very stubborn and difficult to control with regular antibiotics. That's why Tedizolid is mainly used to treat some of those severe bacterial infections.

The most important thing is that this medicine is only used to treat bacterial infections. It will not cure viral infections like the common cold or flu. Therefore, your doctor will only prescribe this medicine after determining that your illness is caused by bacteria.

Things you need to tell your doctor before taking this medicine

Before you start using this medicine, it is very important to give your doctor a complete description of your health condition, especially these points.

  • Do you have low blood counts, such as white blood cells?
  • Have you ever had an allergic reaction to Tedizolid, any other antibiotic, other medicine, food, or dye?
  • Are you currently pregnant or are you hoping to become pregnant in the near future?
  • Are you a breastfeeding mother?

For your safety, it is very important to talk openly with your doctor about anything like this, without hiding anything.

How do you use this medicine?

This medicine is given through a vein (intravenous infusion), similar to a saline solution. This treatment is usually given under the supervision of medical staff in a hospital or clinic.

However, in some special cases, you may be able to do this treatment at home. If so, you will receive special instructions on how to do it and how to store the medicine.

The most important things to remember:

  • Take the exact dose at the exact time.
  • Even if you feel a little better, do not stop taking the medicine for the full number of days prescribed by your doctor. If you don't, the infection may come back.
  • This medicine has been prescribed for you only. Never share it with anyone else.

What to do if you take too much medicine (overdose)?

If you have any suspicion that you have taken more than the prescribed dose of this medicine, immediately call the National Poisons Information Centre at the Colombo National Hospital, or go to the Emergency Department (ETU) of the nearest hospital. Do not delay.

What if I miss a dose of medicine?

If you miss a dose, take it as soon as you remember. However, if it is less than 8 hours before your next dose, skip the missed dose and take your next dose at the regular time. Never take a double dose.

Other things that may interact with Tedizolid (Interactions)

Some medications may interact with this medicine, so it is important to tell your doctor about all medications you are taking.

  • Birth control pills: This is very important. Birth control pills may be less effective while taking Tedizolid. This means there is a risk of pregnancy. So if you are using birth control pills, be sure to talk to your doctor about using another form of birth control while taking this treatment.

In addition, tell your doctor about any other medications, vitamins, herbs, and dietary supplements you are taking. Also, tell your doctor if you smoke or drink alcohol.

What are the possible side effects?

Like any medicine, Tedizolid can cause some side effects. However, not everyone gets them. Let's break these down into two categories.
