Precautions

It is very important that your doctor check your or your child's progress at regular visits to make sure this medicine is working properly. Blood tests may be needed to check for unwanted effects.

Do not use this medicine if you or your child are also using alfuzosin (Uroxatral®), dronedarone (Multaq®), elbasvir/grazoprevir (Zepatier®), ivabradine (Corlaonor®), lomitapide (Juxtapid®, Lojuxta®), lovastatin (Altocor®, Altoprev®, Mevacor®), lurasidone (Latuda®), naloxegol (Movantik®, Moventig®), oral midazolam (Versed®), pimozide (Orap®), ranolazine (Ranexa®), rifampin (Rifadin®, Rimactane®), sildenafil (Revatio®), simvastatin (Simcor®, Vytorin®, Zocor®), triazolam (Halcion®), or ergot medicines (eg, dihydroergotamine, ergotamine, methylergonovine, Cafergot®, D.H.E. 45®, Ergomar®, Ergostat®, Methergine®, Migranal®, Wigraine®). Do not use this medicine together with colchicine (Colcrys®) if you have kidney or liver disease.

Birth control pills may not work as well while you are using darunavir (the active ingredient contained in Prezista) To keep from getting pregnant, use an additional form of birth control along with your pills. Other forms of birth control include condoms, diaphragm, contraceptive foam, or jelly. If you think you have become pregnant while using this medicine, tell your doctor right away.

Check with your doctor right away if you or your child 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.

This medicine may increase blood sugar levels. Check with your doctor right away if you or your child have increased thirst or increased urination. If you notice a change in the results of your or your child's blood or urine sugar tests, or if you have any questions, check with your doctor.

Your immune system may get stronger when you start taking HIV medicines. Tell your doctor right away if you or your child 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, or Guillain-Barré syndrome) may also occur.

Serious skin reactions, including Stevens-Johnson syndrome, toxic epidermal necrolysis, drug reaction with eosinophilia and systemic symptoms (DRESS), and acute generalized exanthematous pustulosis can occur with this medicine. Check with your doctor right away if you or your child have black, tarry stools, blistering, peeling, or loosening of the skin, chest pain, chills, cough, diarrhea, fever, itching, joint or muscle pain, painful or difficult urination, red irritated eyes, red skin lesions, often with a purple center, sore throat, sores, ulcers, or white spots in the mouth or on the lips, swollen glands, unusual bleeding or bruising, or unusual tiredness or weakness.

This medicine may cause you to have excess body fat. Tell your doctor if you or your child 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.

This medicine may increase the risk of bleeding in patients with hemophilia (a bleeding disorder). Talk with your doctor about this risk.

This medicine will not keep you from giving HIV to your partner during sex. Make sure you understand this and practice safe sex, even if your partner also has HIV, by using a latex condom or other barrier method. This medicine will also not keep you from giving HIV to other people if they are exposed to your blood. Do not re-use or share needles with anyone.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription and nonprescription (over-the-counter [OTC]) medicines, and herbal (eg, St. John's wort) or vitamin supplements.
