Did your doctor prescribe you a medicine called Omadacycline? You may have been a little nervous when you heard the name. But don't worry. This is a strong antibiotic that is used to treat certain bacterial infections in the body. So it's very important that we know exactly what this medicine is and what it can do. Let's talk about it simply and clearly.
Simply put, what is Omadacycline?
Omadacycline is a drug that belongs to the tetracycline class of antibiotics. Its main function is to destroy certain bacteria that enter our bodies and cause disease. Think of our bodies as a country, and bacteria are like the enemies that have invaded that country. Omadacycline is like a special army that fights against those enemies.
But there is one very important thing to remember. This medicine only works for bacterial infections. It has no effect on viral infections like the common cold and flu. Therefore, use this medicine only if your doctor has diagnosed the exact disease and prescribed it. This medicine may also come under the brand name NUZYRA.
Things you need to tell your doctor before taking medicine
Before starting this medication, it is very important to give your doctor a complete description of yourself. Because that information will determine whether this medication is right for you or not. Be sure to tell them the following:
- Allergies: Tell your doctor if you have any allergies to Omadacycline or other tetracyclines. Also tell your doctor if you have any allergies to any other medications, foods, dyes, or preservatives.
- Pregnancy: If you are pregnant or trying to get pregnant, be sure to tell your doctor.
- Breastfeeding: If you are a mother who is breastfeeding your child, inform your doctor about this as well.
It is very important for your safety to talk to the doctor without hiding this information.
How do you use this medicine?
Omadacycline is a vaccine that is given through a vein (infused into a vein). It is usually given to you by medical staff in a hospital or clinic. However, in some cases, on the advice of your doctor, you may need to receive this vaccine at home.
If you are going to use it at home, you will be well-informed about how to prepare it and how to inject yourself (or a family member). Never change the way your doctor tells you to. Take the exact dose, at the exact time. Do not stop taking the medicine until your doctor tells you to finish the treatment.
Very important: Never throw used needles and syringes in the trash. They should be placed in a special sharps container. If you don't have one, ask your doctor or clinic for one.
What if the medication dose increases?
If you think you have taken an overdose, go to the nearest hospital Emergency Department (ETU) immediately. Or call the National Poisons Information Centre at the Colombo National Hospital for advice.
What other things can interact with the medication?
Some medications, foods, and supplements can interact with Omadacycline. Therefore, tell your doctor about all the medications you take (including vitamins and herbal remedies). The table below explains this further.
