What is WAYMADE-MARAVIROC used for?
WAYMADE-MARAVIROC is used for the treatment of HIV-1 (Human Immunodeficiency Virus type 1) infection in adults. HIV is the virus that causes AIDS (Acquired Immune Deficiency Syndrome).
WAYMADE-MARAVIROC is a type of anti-HIV medicine called a CCR5 antagonist. WAYMADE-MARAVIROC is used in combination with other anti-HIV medicine.
WAYMADE-MARAVIROC does not cure HIV infection or AIDS. People taking WAYMADE-MARAVIROC may still develop infections or other conditions associated with HIV infection. Although WAYMADE-MARAVIROC is not a cure for HIV or AIDS, WAYMADE-MARAVIROC can help reduce your risks of getting illnesses associated with HIV infection (AIDS and opportunistic infection).
This medicine is prescribed for your condition. Do not use it for any other condition. Do not give WAYMADE-MARAVIROC to other people, even if they have the same symptoms you have. It may harm them.
Your healthcare professional may take blood samples to determine if you have been infected with CCR5-tropic HIV and determine if WAYMADE-MARAVIROC is an appropriate treatment for you.
How does WAYMADE-MARAVIROC work?
WAYMADE-MARAVIROC works by blocking a receptor called CCR5 that a type of HIV uses to enter cells in your blood called CD4 or T-cells (these are types of white blood cells). This virus type is called “CCR5-tropic HIV.” WAYMADE-MARAVIROC can lower the amount of HIV in the blood (called “viral load”) and increase the number of CD4(T) cells (a type of white blood cell). This may keep your immune system

How to take WAYMADE-MARAVIROC:
Usual dose:
Take WAYMADE-MARAVIROC exactly as your healthcare professional has told you. WAYMADE-MARAVIROC should be taken every day with other medicines used to treat HIV.
The recommended dose of WAYMADE-MARAVIROC in adults is 300 mg two times a day.
Your healthcare professional may need to change the amount of WAYMADE-MARAVIROC you take depending on what other medicines you are taking. The amount of WAYMADE-MARAVIROC you take may also be changed if you have kidney problems. Do not start or stop any other medicines without talking to your healthcare professional first.
WAYMADE-MARAVIROC can be taken with or without food. WAYMADE-MARAVIROC tablets should be swallowed with plenty of water. Do not chew the tablets.
To control your HIV infection and to stop your illness from getting worse, you must keep taking all your medicines, unless your healthcare professional tells you otherwise.
It is very important to take all your anti-HIV medicines as prescribed and at the right times of day. This can help your medicines work better. It also lowers the chance that your medicines will stop working to fight HIV (drug resistance).
Be sure to keep a supply of your anti-HIV medicines. When your WAYMADE-MARAVIROC supply starts to run low, get more from your healthcare professional or pharmacy. Do not wait until your medicine runs out to get more. This is very important because the amount of virus in your blood may increase if the medicine is stopped for even a short period of time.
You should never stop taking WAYMADE-MARAVIROC or your other HIV medicines without talking to your healthcare professional.
