Interactions between your drugs

Moderate

posaconazole givinostat

Applies to: posaconazole and givinostat

Using givinostat together with posaconazole may increase the risk of experiencing a change in the electrical activity of your heart called QT prolongation, which may result in irregular heartbeats that can be life-threatening. You might be more susceptible to this risk if you have heart problems or electrolyte disturbances (for example, magnesium or potassium loss due to severe or prolonged diarrhea or vomiting, which are commonly reported as side effects of givinostat treatment). Your doctor may be able to prescribe alternatives that do not interact, or you may need more frequent monitoring of your electrocardiogram to safely use both medications. You should seek immediate medical attention if you experience an irregular heartbeat or feel dizzy, lightheaded, or faint during treatment. 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: 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

givinostat food

Applies to: givinostat

Food increases the absorption of givinostat. To ensure adequate blood levels of the medication, givinostat should be administered with food. Additionally, food can help mask the bitter taste of the oral suspension. Follow up with your healthcare professional if you have any additional questions.
