Uses

Uses

This product is used to help control HIV infection. It helps to decrease the amount of HIV in your body so your immune system can work better. This lowers your chance of getting HIV complications (such as new infections, cancer) and improves your quality of life. This product contains 4 different medications: darunavir, cobicistat, emtricitabine, and tenofovir alafenamide. Darunavir is known as a protease inhibitor. Cobicistat helps darunavir work better. Emtricitabine is called a nucleoside reverse transcriptase inhibitor, while tenofovir alafenamide is called a nucleotide reverse transcriptase inhibitor; both kinds of drugs are often called NRTIs.

Darunavir/cobicistat/emtricitabine/tenofovir alafenamide is not a cure for HIV infection. To decrease your risk of spreading HIV disease to others, do all of the following: (1) continue to take all HIV medications exactly as prescribed by your doctor, (2) always use an effective barrier method (latex or polyurethane condoms/dental dams) during all sexual activity, and (3) do not share personal items (such as needles/syringes, toothbrushes, and razors) that may have contacted blood or other body fluids. Consult your doctor or pharmacist for more details.

How to use Symtuza

Read the Patient Information Leaflet if available from your pharmacist before you start taking this medication and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth with food as directed by your doctor, usually once daily. If you have trouble swallowing this medication whole, you may split the tablet with a tablet cutter before taking it. Take each part of the split tablet right away.

It is very important to continue taking this medication exactly as prescribed by your doctor. Do not skip any doses.

For the best effect, take this medication at evenly spaced times. To help you remember, take this medication at the same time every day.

Do not take more or less of this drug than prescribed or stop taking it even for a short time unless directed to do so by your doctor. Doing so may cause the amount of virus to increase, make the infection more difficult to treat (resistant), or worsen side effects.

Side Effects

Side Effects

Diarrhea, nausea, headache, or tiredness may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

As your immune system gets stronger, it can begin to fight off infections you already had, possibly causing disease symptoms to come back. You could also have symptoms if your immune system becomes overactive. This reaction may happen at any time (soon after starting HIV treatment or many months later). Get medical help right away if you have any serious symptoms, including: unexplained weight loss, severe tiredness, muscle aches/weakness that doesn't go away, headaches that are severe or don't go away, joint pain, numbness/tingling of the hands/feet/arms/legs, vision changes, signs of infection (such as fever, chills, swollen lymph nodes, trouble breathing, cough, non-healing skin sores), signs of an overactive thyroid (such as irritability, nervousness, heat intolerance, fast/pounding/irregular heartbeat, bulging eyes, unusual growth in the neck/thyroid known as a goiter), signs of a certain nerve problem known as Guillain-Barre syndrome (such as trouble breathing/swallowing/moving your eyes, drooping face, paralysis, trouble speaking).

Tell your doctor right away if you have any serious side effects, including: signs of kidney problems (such as change in the amount of urine, pink/bloody urine), easy bruising/bleeding.

Rarely, this medication can cause severe (sometimes fatal) liver and blood problems (lactic acidosis). Tell your doctor right away if you develop symptoms of liver problems (such as nausea/vomiting that doesn't stop, loss of appetite, stomach/abdominal pain, yellowing eyes/skin, dark urine) or lactic acidosis (such as deep/rapid breathing, drowsiness, nausea/vomiting, unusual weakness).

This medication may rarely make your blood sugar rise, which can cause or worsen diabetes. Tell your doctor right away if you have symptoms of high blood sugar such as increased thirst/urination. If you already have diabetes, check your blood sugar regularly as directed and share the results with your doctor. Your doctor may need to adjust your diabetes medication, exercise program, or diet.

Changes in body fat may occur while you are taking this medication (such as increased fat in the upper back and stomach areas, decreased fat in the arms and legs). The cause and long-term effects of these changes are unknown. Discuss the risks and benefits of treatment with your doctor, as well as the possible use of exercise to reduce this side effect.

This medication can commonly cause a rash that is usually not serious. However, you may not be able to tell it apart from a rare rash that could be a sign of a severe reaction. Get medical help right away if you develop any rash, especially with symptoms such as fever, tiredness, muscle/joint pain, blisters, mouth sores, or red/swollen eyes.

A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
