Patient Medication Information: uses, side effects, how to take - Auro-Darunavir
What is Auro-Darunavir used for?
- for the treatment of HIV (Human Immunodeficiency Virus) infection
- in adults
- in children who weigh at least 40 kg and have taken anti-HIV medicines in the past
- always with a low dose (100 mg) of ritonavir (NORVIR) and
- in combination with other anti-HIV medicines.
How does Auro-Darunavir work?
HIV is the virus that causes AIDS (Acquired Immune Deficiency Syndrome). Auro-Darunavir is a type of anti-HIV medicine called a protease (PRO-tee-ase) inhibitor. Auro-Darunavir blocks HIV protease, an enzyme which is needed for HIV to multiply. When used with other anti-HIV medicines, Auro-Darunavir can help to reduce the amount of HIV in your blood (called “viral load”) and increase your CD4+ (T) cell count. HIV infection destroys CD4+ (T) cells, which are important to the immune system. The immune system helps fight infection. Reducing the amount of HIV and increasing the CD4+ (T) cell count may improve your immune system.
Auro-Darunavir does not cure HIV infection or AIDS. At present, there is no cure for HIV infection.

To help avoid side effects and ensure proper use, talk to your healthcare professional before you take Auro-Darunavir. Talk about any health conditions or problems you may have, including if you:
- have diabetes. Anti-HIV medicines, such as Auro-Darunavir, might increase your blood sugar levels.
- have liver problems, including hepatitis B and/or C.
- have hemophilia. Anti-HIV medicines, such as Auro-Darunavir, might increase your risk of bleeding.
- are allergic to sulpha medications.
- have had pancreatitis in the past.
- have advanced HIV infection.
- are 65 years of age or older.
Other warnings you should know about:
Auro-Darunavir does not reduce the risk of passing HIV to others through sexual contact, sharing needles, or being exposed to your blood. For your health and the health of others, it is important to always practice safer sex by using a latex or polyurethane condom or other barrier method to lower the chance of sexual contact with any body fluids. Never use or share dirty needles.
People taking Auro-Darunavir may still develop infections or other illnesses associated with HIV infection. Because of this, it is very important for you to remain under the care of a healthcare professional.
Pregnancy: Tell your healthcare professional immediately if you are pregnant or planning to get pregnant. It is not known if Auro-Darunavir can harm your unborn baby. You must not take Auro-Darunavir during pregnancy, unless your healthcare professional believes the benefit is greater than the risk to your unborn baby. If you take Auro-Darunavir while you are pregnant, talk to your healthcare professional about how you can be included in the Antiretroviral Pregnancy Registry.
Breast-feeding: Do not breast-feed if you are taking Auro-Darunavir because of the possibility of your baby becoming infected with HIV through your breast milk and because of the unknown effects of the medicine on your baby. Talk with your healthcare professional about the best way to feed your baby.
Auro-Darunavir should not be used in children who weigh under 40 kg. Talk to your healthcare professional if your child has never taken an HIV medicine before.
Auro-Darunavir must always be used with low-dose ritonavir (NORVIR). Your healthcare professional will tell you how to take Auro-Darunavir and which medicines you can take with
Auro-Darunavir. Tell your healthcare professional if you take other anti-HIV medicines (e.g., rilpivirine). Auro-Darunavir can be combined with some other anti-HIV medicines while other combinations are not recommended.
Auro-Darunavir can interact with many other medicines. Sometimes serious side effects will happen if you take Auro-Darunavir with some other medicines (see Do not use Auro-Darunavir if:).
Auro-Darunavir should not be used with phenobarbital, phenytoin, rifampin or St. John’s wort because Auro-Darunavir may not work as well if you take these medicines with it.
Auro-Darunavir should not be used with vardenafil, because you may be at increased risk of side effects of vardenafil such as low blood pressure, visual changes and penile erection lasting more than 4 hours.
Tell your healthcare professional if you are taking estrogen-based contraceptives. Auro-Darunavir might reduce the effectiveness of estrogen-based contraceptives (birth control). Therefore, additional or alternative (non-hormonal) methods of contraception, such as a condom, are recommended.
Check-ups and Testing: Liver problems that may occasionally be severe have been reported. Your healthcare professional should do blood tests before you take Auro-Darunavir and while you are taking it. If you have chronic hepatitis B or C infection, your healthcare professional should check your blood tests more often because you have an increased chance of developing liver problems.
Tell your healthcare professional about all the medicines you take, including any drugs, vitamins, minerals, natural supplements or alternative medicines.
The following may interact with Auro-Darunavir. Your healthcare professional might want to do some additional blood tests.

What are possible side effects from using Auro-Darunavir?
These are not all the possible side effects you may have when taking Auro-Darunavir. If you experience any side effects not listed here, tell your healthcare professional.
Rash has been reported in 10.3% of patients receiving Auro-Darunavir. Occasionally a rash can be severe or potentially life threatening. In patients taking Auro-Darunavir and raltegravir, rashes (generally mild or moderate) may occur more frequently than in patients taking either drug separately. If you develop a severe rash (e.g. blisters, peeling skin) which may be accompanied with symptoms such as fever, fatigue, muscle aches and pain, and liver problems, stop use of Auro-Darunavir and contact your healthcare professional right away.
Common side effects may include:
- diarrhea
- nausea and vomiting
- headache
- abdominal pain
- darunavir crystals may form in the kidney. These can cause kidney disease.
Some side effects are typical for anti-HIV medicines in the same family as Auro-Darunavir. These are:
- high blood sugar (hyperglycemia) and diabetes or worsening of diabetes. You may need to start or change your diabetes medicine.
- increased bleeding in patients with hemophilia.
- changes in body fat which may include an increased amount of fat in the upper back and neck, breast, and around the back, chest, and stomach area. Loss of fat from the legs, arms, and face may also happen. The exact cause and long-term health effects of these conditions are not known.
- increases in triglycerides and cholesterol (forms of fat that are found in your blood). Your healthcare professional may order blood testing for you.
- development of pancreatitis (inflammation of the pancreas) with symptoms such as abdominal pain, nausea and vomiting.
- changes in your immune system (Immune Reconstitution Inflammatory Syndrome). Your immune system may get stronger and begin to fight infections that have been hidden in your body for a long time, or you could develop an autoimmune disease in which your immune system reacts against your own body (e.g. Grave’s disease (which affects the thyroid gland), autoimmune hepatitis, Guillain-Barre syndrome (which affects the nervous system) or polymyositis (which affects the muscles). This may develop at any time, sometimes months after the start of HIV therapy. Sometimes symptoms can be severe, so if you develop high temperature (fever), joint or muscle pain, redness, rash, swelling, abdominal pain, yellowing of the skin and eyes, or fatigue or any new symptoms contact your healthcare professional right away.
