How should I take tenofovir?
Before you start treatment with tenofovir, your doctor may perform tests to make sure you do not have HIV (if you are being treated for hepatitis B) or hepatitis B (if you are being treated for HIV).
Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.
Take this medicine at the same time each day.
Some forms of tenofovir should be taken with food. Carefully follow all instructions on your medicine label.
Tenofovir oral powder should be mixed with soft food such as applesauce, yogurt, or baby food. Do not mix the oral powder with liquid.
Swallow the tablet whole and do not crush, chew, or break it. Tell your doctor if you or your the child taking tenofovir has trouble swallowing a tablet.
Doses are based on weight in children. Your child's dose needs may change if the child gains or loses weight.
You will need medical tests.
Use all HIV medications as directed. Do not change your dose or stop using a medicine without your doctor's advice. Remain under the care of a doctor.
Store tightly closed at room temperature, away from moisture and heat.
If you've had hepatitis B, it may come back or get worse after you stop using tenofovir. You may need liver function tests while using this medicine and for several months after you stop.
