Use your medication properly to control infections. HIV can be transmitted to your child if you do not control the virus during pregnancy. You may have your name listed in a registry that tracks the effects of antiviral medicines on a baby. Fosamprenavir may make birth-control pills ineffective. You may experience abnormal liver function tests if you take fosamprenavir with ritonavir and use birth-control pills. Ask your doctor if you can use non-hormonal birth control to prevent pregnancy (condoms, diaphragms with spermicide). Breast-feeding is not recommended for women with HIV/AIDS. Even if the baby is not born with HIV, it can be transmitted to the child through your breast milk. Fosamprenavir shouldn't be given to a baby younger than four weeks (28 days).
