Drug Interaction Report

Posaconazole can significantly increase the blood levels of daclatasvir. This may increase the risk and/or severity of side effects such as headache, fatigue, nausea, and diarrhea. Talk to your doctor if you have any questions or concerns. Your doctor may already be aware of the interaction, but has determined that this is the best course of treatment for you and has taken appropriate precautions or made dose adjustments and is monitoring you closely for any potential complications. Your doctor may also be able to prescribe alternatives that do not interact. 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.

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.
