Aptivus (tipranavir) is a prescription medication approved by the U.S. Food and Drug Administration (FDA) for use with other HIV medicines to treat human immunodeficiency virus type 1 (HIV-1) in adults and children who weigh 36 kilograms or more.

How Aptivus Works and How It’s Taken

Aptivus is a type of HIV medicine called a protease inhibitor. It blocks an enzyme that HIV needs to make mature copies of itself.

Doctors prescribe Aptivus for adults and children who weigh 36 kilograms or more. It is for people who have taken HIV medicines before and whose HIV-1 is resistant to more than one protease inhibitor.

Aptivus is used with ritonavir and other HIV medicines. Aptivus is not recommended for people who have never taken HIV medicines before.

HIV-1 is the virus that causes acquired immune deficiency syndrome (AIDS).

Aptivus comes as capsules taken by mouth. It must be taken twice daily with ritonavir and food. The capsules must be swallowed whole. Do not open or chew them.

Typical Dosing for HIV

The recommended dose for adults and children weighing 36 kilograms or more is 500 milligrams of Aptivus, taken as two 250-milligrams capsules twice daily. Each dose is taken with 200 milligrams of ritonavir.

This information is based on prescribing information, but your healthcare provider may tailor your treatment plan. Always follow their guidance.

Aptivus Side Effects

In clinical studies of Aptivus taken with ritonavir, the most common side effects were reported in about 4 percent to 15 percent of people. These include:

  • Diarrhea
  • Nausea
  • Fever
  • Vomiting
  • Fatigue (tiredness)
  • Headache
  • Abdominal (stomach) pain

Serious Side Effects and Warnings

Aptivus can cause serious side effects that may require immediate medical attention. These include:

  • Liver problems — These problems can include hepatitis and liver failure, which can be fatal.
  • Bleeding in the brain — Intracranial hemorrhage can be fatal.
  • Serious bleeding — Aptivus may increase bleeding risk, including in people with hemophilia.
  • Severe skin rash — Rash can be serious and may include hives or sun sensitivity.
  • Diabetes and high blood sugar — New or worsening diabetes, sometimes with diabetic ketoacidosis, can occur.
  • Immune reconstitution syndrome — Immune system changes can trigger inflammation as your body starts fighting infections again.
  • Changes in body fat — Fat redistribution or accumulation can occur, such as increased belly fat or a “buffalo hump.”
  • High blood fats — Cholesterol and triglycerides can increase.

Get medical help right away if you think you are having a serious reaction.

What To Know Before Taking Aptivus

Before starting Aptivus, your doctor will do liver blood tests.

Before taking Aptivus, tell your healthcare provider if you:

  • Have hemophilia or another condition that raises your risk of bleeding
  • Have had trauma or surgery
  • Take medicines that raise your risk of bleeding
  • Take high doses of vitamin E
  • Have liver problems, including hepatitis B or hepatitis C
  • Have high cholesterol or high triglycerides
  • Have a sulfa allergy
  • Are allergic to tipranavir or any ingredient in Aptivus
  • Have diabetes

Tell your doctor about all medicines you take, including prescription drugs, over-the-counter medicines, vitamins, and herbal supplements.

Do not take Aptivus if you have moderate or severe liver problems.

Do not take Aptivus with:

  • Alfuzosin
  • Amiodarone, bepridil, flecainide, propafenone, or quinidine
  • Rifampin
  • Dihydroergotamine, ergonovine, ergotamine, or methylergonovine
  • Cisapride
  • St. John’s wort
  • Atorvastatin, lovastatin, or simvastatin
  • Pimozide or lurasidone
  • Sildenafil when used for pulmonary arterial hypertension
  • Oral midazolam or triazolam

If you miss a dose, take Aptivus with ritonavir as soon as you remember. Take your next dose at the usual time. Do not take two doses at once.

Refill Aptivus before you run out. Stopping it, even for a short time, may allow the amount of HIV in your blood to rise. The virus may also become harder to treat.

Tell your healthcare provider if you are pregnant or plan to become pregnant. A pregnancy registry tracks outcomes in people who take Aptivus during pregnancy. Healthcare providers can register pregnancies by visiting the Antiretroviral Pregnancy Registry website or calling 800-258-4263.

Aptivus may make estrogen-based birth control pills less effective. Use a nonhormonal form of birth control during treatment.

Talk with your healthcare provider before breastfeeding. Breastfeeding may pass HIV-1 to a child who does not have HIV-1. It may also make HIV-1 harder to treat in a child who has HIV-1. A breastfed child may also have side effects similar to those seen in adults.

Community FAQs

These answers are fact-checked by our editorial staff.

How effective is Aptivus for HIV?

In studies of adults who had taken HIV medicines before, Aptivus was used with ritonavir and other HIV medicines.

By week 48:

  • 33.8 percent of people taking Aptivus with ritonavir had at least a 90 percent drop in the amount of HIV-1 in their blood. This happened in 14.9 percent of people in the comparison group.
  • 30.3 percent had fewer than 400 copies of HIV-1 per milliliter of blood. “Copies per milliliter” means how many copies of the virus are found in a small amount of blood. This happened in 13.6 percent of people in the comparison group.
  • 22.7 percent had fewer than 50 copies per milliliter. This means the amount of virus in the blood was very low. This happened in 10.2 percent of people in the comparison group.
  • The typical increase in CD4-positive cells was 23 cells per cubic millimeter with Aptivus and ritonavir, compared with 4 cells per cubic millimeter in the comparison group. CD4-positive cells are immune cells that help the body fight infections.

How long does Aptivus take to work for HIV?

The studies measured treatment results through week 48. They also checked by week 8 for people who did not have an early response.

The study does not give an exact time when a person will feel or notice improvement.

Should I take Aptivus for HIV if I have an infection?

People with chronic hepatitis B or hepatitis C have a higher risk of serious liver problems while taking Aptivus with ritonavir.

Liver problems, including hepatitis and liver failure, have been reported. Some cases were fatal.

Your healthcare provider should check your liver before treatment and often during treatment.

Stop taking Aptivus with ritonavir and get medical care if you develop signs of hepatitis.

Aptivus is also not recommended for people who have never taken HIV medicines before.
