Tenofovir DF tablets should be swallowed whole and can be taken with or without food. People who are unable to swallow the tablets whole may take the oral powder. Use the provided dosing scoop to measure the oral powder. Mix the oral powder with soft foods that can be swallowed without chewing, such as applesauce, baby food, or yogurt. Take the dose of oral powder right after mixing it. Do not mix the oral powder with liquid.

Always take tenofovir DF in combination with other anti-HIV medicines.

If you take too much tenofovir DF, contact your local poison control center (1-800-222-1222) or go to the nearest hospital emergency room right away.

For more information on how to take tenofovir DF, see the FDA drug label from DailyMed. (DailyMed is a federal website that includes the most recent drug labels submitted to FDA.)


What should I do if I forget a dose?

Take the missed dose as soon as you remember it. But if it is almost time for your next dose, skip the missed dose and just take your next dose at the regular time. Do not take two doses at the same time to make up for a missed dose.
