It may be helpful to take Genvoya around the same time each day. This helps maintain a steady level of the drug in your body so Genvoya can work effectively.

The timing of your Genvoya dose may need to be adjusted if you also take certain medications or supplements. For example, be sure to take Genvoya at least 2 hours apart from any products that contain calcium, magnesium, iron, or other minerals. Taking these products too close to Genvoya can make Genvoya less effective. For more information, talk with your doctor or pharmacist.

Some pharmacies offer labels with large print, braille, or a code you scan with a smartphone to convert text to speech. If your local pharmacy doesn’t have these options, your doctor or pharmacist might be able to recommend a pharmacy that does.

If you’re having trouble opening medication bottles, ask your pharmacist about putting Genvoya in an easy-open container. They also may recommend tools that can make it easier to open bottles.

The Genvoya prescribing information doesn’t state what to do in case of a missed dose. If you miss a dose of Genvoya, talk with your doctor. They’ll tell you whether to take the missed dose or skip it. They’ll also suggest when to take your next scheduled dose.
