Uses
This product contains 3 different medications: emtricitabine, rilpivirine, and tenofovir alafenamide. It 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. Emtricitabine and tenofovir alafenamide belong to a class of drugs known as nucleoside reverse transcriptase inhibitors (NRTIs). Rilpivirine belongs to a class of drugs known as non-nucleoside reverse transcriptase inhibitors (NNRTIs).Emtricitabine/rilpivirine/tenofovir alafenamide is not a cure for HIV infection. To decrease your risk of spreading HIV disease to others, continue to take all HIV medications exactly as prescribed by your doctor. Use an effective barrier method (latex or polyurethane condoms/dental dams) during sexual activity as directed by your doctor. 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 Odefsey
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 a meal as directed by your doctor, usually once daily.
Medications which reduce or block stomach acid (such as proton pump inhibitors/PPIs, H2 blockers, antacids) may reduce the absorption of rilpivirine, making it work less well. Do not take PPIs (such as omeprazole, lansoprazole) while using this medication. If you take antacids, take the antacids at least 2 hours before or at least 4 hours after this medication. If you take H2 blockers (such as famotidine, ranitidine), take them at least 12 hours before or at least 4 hours after this medication.
It is very important to keep taking this medication exactly as prescribed by your doctor. Do not take 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 and/or make the infection more difficult to treat (resistant).
Do not increase your dose or take this medication more often than prescribed. Your condition will not improve any faster, and your risk of side effects may increase.
For the best effect, take this medication at evenly spaced times. To help you remember, take this medication at the same time every day.
Side Effects
Headache or trouble sleeping may occur. If either of these effects lasts or gets worse, tell your doctor or pharmacist promptly.
Remember that this medication has been prescribed because your doctor 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 unsteadiness, loss of coordination, trouble swallowing/speaking/chewing, trouble moving your eyes), signs of liver disease (such as nausea/vomiting that doesn't stop, loss of appetite, stomach/abdominal pain, yellowing eyes/skin, dark urine).
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), mental/mood changes (such as depression, thoughts of suicide).
Rarely, this medication can cause a severe (sometimes fatal) blood problem (lactic acidosis). Tell your doctor right away if you develop symptoms of lactic acidosis (such as deep/rapid breathing, drowsiness, nausea/vomiting, unusual weakness).
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.
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.
