Interactions between your drugs

Moderate

posaconazole telaprevir

Applies to: Noxafil (posaconazole) and telaprevir

Using telaprevir together with posaconazole may increase the blood levels and effects of both medications. Increased blood levels of posaconazole can cause an irregular heart rhythm that may be serious. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if your condition changes or you experience increased side effects. You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, shortness of breath, or fast or pounding heartbeats. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Drug and food interactions

Moderate

posaconazole food

Applies to: Noxafil (posaconazole)

Food significantly increases the absorption of posaconazole from the tablet or suspension formulations. The manufacturer recommends that you take the tablet with food and the oral suspension during or immediately (within 20 minutes) after a full meal. If you cannot eat a full meal, you should take the oral suspension with a liquid nutritional supplement like Ensure or an acidic carbonated beverage like ginger ale. Do not take these medications on an empty stomach, as it may lead to inadequate blood levels and reduced effectiveness. Ask your doctor before using alcohol together with posaconazole from delayed release suspension formulations as this may cause an increase in side effects. Talk to your doctor or pharmacist if you have any questions on how to use the medication properly.

Moderate

telaprevir food

Applies to: telaprevir

Food significantly increases the absorption of telaprevir. Within 30 minutes before you take each dose of telaprevir, you should eat a meal or snack containing approximately 20 grams of fat. Taking it on an empty stomach may lead to inadequate blood levels and reduced effectiveness of the medication. Examples of some foods that could be taken with telaprevir include: bagel with cream cheese; half cup of nuts; 3 tablespoons of peanut butter; 1 cup of ice cream; 2 ounces of American or cheddar cheese; 2 ounces of potato chips; or half cup of trail mix. Talk to your healthcare provider if you have additional questions about how to take telaprevir.
