The Tavneos dosage your doctor prescribes will depend on certain factors. These include any other medications you may take or health conditions you may have.

Dosage adjustments

Your doctor may need to decrease your dosage if you take certain medications, such as CYP3A4 inhibitors. These drugs decrease the activity of the CYP3A4 enzyme, which helps the liver break down medication.

Due to the way these drugs work, they may affect how well your body can process Tavneos. To find out what drugs may interact with Tavneos, talk with your doctor. It’s important to tell them about any medications you take.

Tavneos comes as an oral capsule that you swallow whole. Do not divide, crush, chew, or place the capsule in water. Be sure to take your dose with a meal or snack.

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

If you have trouble swallowing capsules, see this article for tips on how to take this form of medication. You can also 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 Tavneos in an easy-open container. They also may recommend tools that can make it easier to open bottles.

If you miss a dose of Tavneos, skip the missed dose. Then, take your next dose as scheduled. Do not take two doses to make up for the missed dose. If you’re not sure whether you should take a missed dose or skip it, talk with your doctor or pharmacist.

To help make sure that you don’t miss a dose, try using a medication reminder. This can include setting an alarm or putting a note where you’ll see it, such as on your bathroom mirror or bedside table. You could also download a reminder app on your phone.

It’s important that you don’t take more Tavneos than your doctor prescribes. For some medications, taking more than the recommended amount may lead to harmful effects or overdose.

If you take more than the recommended amount of Tavneos

Call your doctor right away if you believe you’ve taken too much Tavneos. Another option is to call America’s Poison Centers at 800-222-1222 or use its online tool. If you have severe symptoms, immediately call 911 or your local emergency number, or go to the nearest emergency room.
