Interactions between your drugs

Moderate

pralsetinib daprodustat

Applies to: pralsetinib and daprodustat

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with pralsetinib may alter the plasma concentrations of drugs that are substrates of CYP450 2C8, 2C9, 3A4, and/or 3A5. In vitro studies indicate that pralsetinib is both an inhibitor as well as an inducer of CYP450 2C8, 2C9, 3A4, and 3A5. Therefore, pralsetinib may decrease clearance via inhibition or increase clearance via induction of these isoenzymes, resulting in increased or decreased plasma concentrations of agents that are metabolized by one or more of these isoenzymes. Clinical and pharmacokinetic data are currently lacking.

MANAGEMENT: Caution is advised if pralsetinib is used concomitantly with drugs that are substrates of CYP450 2C8, 2C9, 3A4, and/or 3A5, particularly sensitive substrates or those with a narrow therapeutic range. Some authorities recommend avoiding coadministration of pralsetinib with CYP450 2C8, 2C9, 3A4, and/or 3A5 substrates for which minimal concentration changes may lead to therapeutic failure or serious toxicities. If coadministration is required, dosage adjustments as well as clinical and laboratory monitoring may be appropriate whenever pralsetinib is added to or withdrawn from therapy. The prescribing information for concomitant medications should be consulted to assess the benefits versus risks of coadministration and for any dosage adjustments that may be required.

Drug and food interactions

Major

pralsetinib food

Applies to: pralsetinib

Food should not be consumed for at least 2 hours before and at least 1 hour after taking pralsetinib. Do not consume grapefruit, grapefruit juice, any supplements that contain grapefruit, Seville oranges, or Seville orange juice as these products can increase the blood levels of pralsetinib. This may increase the risk and/or severity of serious side effects such as lung problems, liver problems, high blood pressure, fatigue, muscle and joint pain, and bleeding complications. Some sources also warn that combining these medicines could increase the risk of an irregular heart rhythm that may be serious and potentially life-threatening, although it is a relatively rare side effect. You may be more susceptible if you have a heart condition called congenital long QT syndrome, other cardiac disease, conduction abnormalities, or electrolyte disturbance (for example, magnesium or potassium loss due to severe or prolonged diarrhea or vomiting). Talk to your doctor if you have any questions or concerns. 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.

Moderate

daprodustat food

Applies to: daprodustat

Using daprodustat while smoking or drinking alcohol may increase the risk of side effects in the gastrointestinal tract such as stomach inflammation and bleeding. Talk to your doctor if you have any questions or concerns. You should seek immediate medical attention if you have signs and symptoms of gastrointestinal bleeding such as abdominal pain, coughing up or vomiting fresh or dried blood that looks like coffee grounds, black, tarry stools, trouble swallowing, or chest or throat pain. 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 Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
