Have you or someone you know contracted malaria and the doctor prescribed this medicine? Or do you want to know more about this medicine? Then this article will be very important for you. Let's talk about this medicine called Artemether/Lumefantrine, which is often given under the brand name Coartem in our country, in simple terms.
Simply put, what is this medicine?
This is a special medicine that is given to treat malaria. In medical terms, it is an antimalarial agent. When the malaria parasite enters your body, this medicine helps to destroy those parasites and cure you. It contains a combination of two drugs: Artemether and Lumefantrine. These two work together to fight the malaria parasite.
The most important thing is that this is a medicine that should only be used on the prescription of a doctor . Never use a medicine that you think has been given to someone else.

How exactly do I use this medicine?
How to take the medicine
These tablets should be taken by mouth. It is best to take them with a meal or something like milk . This is because the ingredient in this medicine, lumefantrine, is best absorbed by the body when taken with a fatty meal. Therefore, taking the medicine with a meal will give you the best results.
Very important: Do not drink grapefruit juice while taking this medication. This can increase the amount of medication in your body unnecessarily, causing side effects.
If small children have difficulty swallowing pills, they can crush the pill and mix it with 1-2 teaspoons of water in a clean container. This should be done at the time of giving the medicine. Do not prepare it in advance.
Instructions to follow
