This medicine is available only with your doctor's prescription.

This product is available in the following dosage forms:

Tablet

Before Using

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of darunavir and cobicistat combination in children weighing at least 40 kilograms (kg). However, safety and efficacy have not been established in children weighing less than 40 kg. Use is not recommended in children younger than 3 years of age because of darunavir's toxicity.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of atazanavir and cobicistat combination in the elderly. However, elderly patients are more likely to have age-related liver problems, which may require caution for patients receiving this medicine.

Breastfeeding

There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking this medicine, it is especially important that your healthcare professional know if you are taking any of the medicines listed below.

Precautions

It is very important that your doctor check your progress at regular visits, especially during the first few weeks that you take this medicine, to make sure it is working properly. Blood and urine tests may be needed to check for any unwanted effects.

This medicine should not be used together with alfuzosin (Uroxatral®), carbamazepine (Tegretol®), cisapride (Propulsid®), dronedarone (Multaq®), elbasvir/grazoprevir (Zepatier®), ivabradine (Corlaonor®), lomitapide (Juxtapid®, Lojuxta®), lovastatin (Mevacor®), lurasidone (Latuda®), naloxegol (Movantik®, Moventig®), oral midazolam (Versed®), phenobarbital (Luminal®), phenytoin (Dilantin®), pimozide (Orap®), ranolazine (Ranexa®), rifampin (Rifadin®, Rimactane®), sildenafil (Revatio®), simvastatin (Zocor®), St. John's wort, triazolam (Halcion®), or ergot medicines (eg, dihydroergotamine, ergotamine, methylergonovine, Cafergot®, Ergomar®, Wigraine®). Do not use this medicine together with colchicine (Colcrys®) if you have kidney or liver disease.

Using this medicine while you are pregnant can harm your unborn baby. Birth control pills may not work as well to prevent pregnancy when used with this medicine. Use another form of birth control (eg, condoms, spermicide) along with your pills to keep from getting pregnant during treatment with this medicine. If you think you have become pregnant while using this medicine, tell your doctor right away.

Check with your doctor right away if you have pain or tenderness in the upper stomach, pale stools, dark urine, loss of appetite, nausea, unusual tiredness or weakness, or yellow eyes or skin. These could be symptoms of a serious liver problem.

Serious skin reactions (eg, Stevens-Johnson syndrome, toxic epidermal necrolysis, drug rash with eosinophilia and systemic symptoms, and acute generalized exanthematous pustulosis) can occur with this medicine. Check with your doctor right away if you have any of the following symptoms: severe rash, blistering, peeling, or loosening of the skin, chills, cough, diarrhea, itching, joint or muscle pain, red skin lesions, often with a purple center, skin rash, sore throat, sores, ulcers, or white spots in the mouth or on the lips, or unusual tiredness or weakness.

This medicine may increase your risk for kidney problems, including acute kidney failure or Fanconi syndrome (when used together with tenofovir DF). Check with your doctor right away if you have changes in how much you urinate, decreased mental sharpness, nausea, vomiting, loss of appetite, or muscle twitches or cramps.

This medicine may increase blood sugar levels. Check with your doctor if you notice a change in the results of your blood or urine sugar tests.

This medicine may cause you to have excess body fat. Tell your doctor if you notice changes in your body shape, such as an increased amount of fat in the upper back and neck, or around the chest and stomach area. You might also lose fat from the legs, arms, and face.

Your immune system may get stronger when you start taking HIV medicines. Tell your doctor right away if you notice any changes in your health. Sometimes the immune system will start to fight infections that were hidden in your body, such as pneumonia, herpes, or tuberculosis. Autoimmune disorders (eg, Graves' disease, polymyositis, Guillain-Barré syndrome, and autoimmune hepatitis) may also occur.

This medicine does not decrease the risk of transmitting the HIV infection to others through sexual contact or by contaminated blood. Make sure you understand and practice safe sex, even if your partner also has HIV. Avoid sharing needles with anyone.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or non-prescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
