Lenacapavir Oral

WHY is this medicine prescribed?

Lenacapavir oral is used along with other medications to treat human immunodeficiency virus type 1 (HIV-1) in certain adults. Lenacapavir is in a class of medications called HIV capsid inhibitors. It works by decreasing the amount of HIV in the blood. Although lenacapavir does not cure HIV, it may decrease your chance of developing acquired immunodeficiency syndrome (AIDS) and HIV-related illnesses such as serious infections or cancer. Taking these medications along with practicing safer sex and making other life-style changes may decrease the risk of transmitting (spreading) the HIV virus to other people.

HOW should this medicine be used?

Lenacapavir oral comes as a tablet to take by mouth. It is usually taken with or without food once a day for the first two days before starting lenacapavir injection. In some cases, a third dose of lenacapavir oral may be given a week following your first dose of lenacapavir oral. Your doctor will decide how many doses of lenacapavir oral you should receive while or before starting lenacapavir injection. Take lenacapavir at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take lenacapavir exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Lenacapavir controls HIV but does not cure it. Continue to take lenacapavir even if you feel well. Do not stop lenacapavir without talking to your doctor. If you stop taking lenacapavir, your HIV may become more difficult to treat.

What should I know about STORAGE and DISPOSAL of this medication?

Keep this medication in the blister packs until ready to take the doses, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location — one that is up and away and out of their sight and reach. https://www.upandaway.org
