Before using raltegravir, tell your doctor if you are allergic to any drugs, or if you have a muscle disorder, kidney disease, or liver disease.
HIV can be passed to the baby if the mother is not properly treated during pregnancy. Tell your doctor if you are pregnant or plan to become pregnant during treatment. Take all of your HIV medicines as directed to control your infection while you are pregnant.
You should not breast-feed while you are using raltegravir. Women with HIV or AIDS should not breast-feed at all. Even if your baby is born without HIV, you may still pass the virus to the baby in your breast milk.
Taking raltegravir will not prevent you from passing HIV to other people through unprotected sex or sharing of needles. Talk with your doctor about safe methods of preventing HIV transmission during sex, such as using a condom and spermicide. Sharing drug or medicine needles is never safe, even for a healthy person.
Call your doctor at once if you have serious side effects such as easy bruising or bleeding, signs of a new infection, jaundice (yellowing of the skin or eyes), muscle weakness with fever and dark colored urine, or if you urinate less than usual or not at all.
