Summary
bictegravir/emtricitabine/tenofovir

Biktarvy is a complete HIV-1 treatment for adults and children who weigh at least 31 pounds. It combines three medicines into one tablet to help control the virus.

estradiol

Iclevia is a birth control pill. It contains two hormones, a progestin and an estrogen, that work together to prevent pregnancy.

What It Treats
bictegravir/emtricitabine/tenofovir

Biktarvy treats Human Immunodeficiency Virus type 1 (HIV-1) in adults and children weighing at least 31 pounds. It can be used if you have never taken HIV medicine before. It can also replace your current HIV medicine if your virus is under control and you have no resistance to Biktarvy's components.

estradiol

Iclevia is used by women who can get pregnant to prevent pregnancy. It contains two types of hormones. These hormones stop you from releasing an egg and also change the lining of your uterus, which prevents pregnancy.

How It Works
bictegravir/emtricitabine/tenofovir

Biktarvy contains three drugs that each block HIV in different ways. Bictegravir stops HIV from inserting its DNA into your cells. Emtricitabine and tenofovir alafenamide interfere with an enzyme HIV needs to make copies of itself.

estradiol

Iclevia contains two hormones: levonorgestrel (a progestin) and ethinyl estradiol (an estrogen). These hormones prevent pregnancy by stopping ovulation (the release of an egg from the ovary). They also change the lining of the uterus to prevent a fertilized egg from implanting.

Serious Warnings
bictegravir/emtricitabine/tenofovir

If you have both HIV and hepatitis B, stopping Biktarvy can cause your hepatitis B to suddenly get worse. Your doctor will need to monitor your liver closely for several months after you stop taking Biktarvy. You may need to take medicine for hepatitis B.

estradiol

Cigarette smoking increases your risk of serious heart problems from birth control pills. This risk is higher if you are over 35 and smoke more cigarettes. You should not take Iclevia if you are over 35 and smoke.

Pregnancy
bictegravir/emtricitabine/tenofovir

There is a pregnancy registry to track outcomes in women who take Biktarvy during pregnancy. Talk to your doctor about the risks and benefits of taking Biktarvy if you are pregnant or planning to become pregnant. There is not enough data to assess the risk of major birth defects.

estradiol

Do not use Iclevia if you are pregnant. If you become pregnant while taking Iclevia, stop taking it right away. Iclevia can reduce milk production, so you may want to use a different birth control method while breastfeeding.
