Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Abnormal heart rhythms: This medication can cause abnormal heart rhythms. Certain medications (e.g., sotalol, quinidine, thioridazine, chlorpromazine, pimozide, gatifloxacin, moxifloxacin, mefloquine, dolasetron mesylate, tacrolimus) can increase the risk of a type of abnormal heart rhythm called QT prolongation, and should not be used in combination with emtricitabine - rilpivirine - tenofovir.
If you have heart disease and abnormal heart rhythms, or are taking certain medications that can affect heart rhythm, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Bone loss/osteoporosis: This medication may cause increased breakdown of bone by the body. If this happens, bones lose strength and bone fractures may occur.
If you have osteoporosis or bone loss, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Depression: Antiretroviral medications have been known to cause mood swings and symptoms of depression. If you have depression or a history of depression, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
If you experience symptoms of depression such as poor concentration, changes in weight, changes in sleep, decreased interest in activities, or notice them in a family member who is taking this medication contact your doctor as soon as possible.
Fat redistribution: Over time, this medication may change how fat is distributed in your body and may change your body shape. You may notice increased fat in the upper back and neck, breast, around the back, chest, and stomach area; or loss of fat from the legs, arms, and face. The long-term effects of this are not known.
Hepatitis B: There have been reports of serious liver problems while taking emtricitabine or tenofovir, two of the ingredients in this medication. If you are also infected with hepatitis B, you may experience flare-ups of hepatitis B when you stop taking this medication. Do not stop taking this medication without first consulting with your doctor. The safety and effectiveness of this medication when used by people with hepatitis B has not been determined.
Immune reconstitution syndrome: This medication may cause immune reconstitution syndrome, where signs and symptoms of inflammation from previous infections appear. These symptoms occur soon after starting anti-HIV medication and can vary. They are thought to occur as a result of the immune system improving and being able to fight infections that have been present without symptoms (such as pneumonia, herpes or tuberculosis). Report any new symptoms to your doctor immediately.
Kidney function: Kidney failure and severe kidney damage has been reported by people using tenofovir. Kidney disease or reduced kidney function may cause this medication to build up in the body, causing side effects.
If you have reduced kidney function, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
People with severely reduced kidney function should not take this medication.
Lactic acidosis and enlarged fatty liver: Tenofovir, an ingredient in this medication, can cause a rare but serious condition called lactic acidosis (a build-up of lactic acid in the blood) together with an enlarged fatty liver. This tends to occur more often in women, especially if they are overweight. If you experience any of the following symptoms, call your doctor immediately:
Your doctor will monitor your liver function periodically by ordering laboratory tests.
Liver function: Rilpivirine, one of the ingredients in this medication, is largely removed from the body by the liver and may cause liver problems. If you have liver disease or decreased liver function, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
This medication should not be used by people with severely reduced liver function.
If you experience symptoms of liver problems (e.g., abdominal pain, persistent vomiting, feeling unwell, fever, itching, yellowing of the skin and eyes, dark urine), contact your doctor immediately.
Other HIV medications: Emtricitabine - rilpivirine - tenofovir is a combination medication that should not be taken at the same time as any other medication that contains the same active ingredients. This medication should also not be taken at the same time as medications containing lamivudine or adefovir.
Pancreatitis (inflammation of the pancreas): Tenofovir may cause or worsen pancreatitis. If you have a history of or are at risk for developing pancreatitis, you should be closely monitored by your doctor while taking this medication.
Discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
If you develop signs of pancreatitis (e.g., upper left abdominal pain, back pain, nausea, fever, chills, rapid heartbeat, swollen abdomen), contact your doctor.
Stopping the medication: If you stop taking this medication, your HIV infection could get worse. Take the medication exactly as prescribed by your doctor, and do not stop taking the medication without checking with your doctor first.
