Interactions between your drugs

Moderate

naproxen abiraterone

Applies to: Sudafed 12 Hour Pressure+Pain (naproxen / pseudoephedrine) and abiraterone

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with abiraterone acetate may increase the plasma concentrations of drugs that are primarily metabolized by CYP450 2C8. Abiraterone is a potent inhibitor of CYP450 2C8 in vitro. In a drug interaction study with healthy subjects, administration of the CYP450 2C8 substrate pioglitazone with a single 1000 mg dose of abiraterone acetate resulted in a 46% increase in pioglitazone systemic exposure (AUC).

MANAGEMENT: Caution is advised if abiraterone acetate is prescribed with medications that undergo metabolism by CYP450 2C8, particularly those with a narrow therapeutic range. Dosage adjustments as well as clinical and laboratory monitoring may be appropriate for some drugs whenever abiraterone acetate is added to or withdrawn from therapy.

Drug and food interactions

Moderate

abiraterone food

Applies to: abiraterone

Taking abiraterone with food increases the amount of medicine that gets absorbed by the body. This may increase the risk of side effects such as high blood pressure, water retention, and a condition called hypokalemia (low blood potassium), which in severe cases can lead to muscle weakness, paralysis, breathing and swallowing difficulties (due to muscle paralysis), and irregular heart rhythm. You should take abiraterone once a day on an empty stomach. No food should be eaten for at least two hours before and one hour after taking abiraterone. Let your doctor know if you experience nausea, vomiting, constipation, abdominal cramping, confusion, dizziness, lightheadedness, fainting, muscle weakness, muscle cramps, numbness or tingling, rapid heart beat, chest pain, and/or swelling in the legs or feet, as these may be symptoms of hypokalemia or excessive effects of abiraterone. 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

naproxen food

Applies to: Sudafed 12 Hour Pressure+Pain (naproxen / pseudoephedrine)

Ask your doctor before using naproxen together with ethanol. Do not drink alcohol while taking naproxen. Alcohol can increase your risk of stomach bleeding caused by naproxen. Call your doctor at once if you have symptoms of bleeding in your stomach or intestines. This includes black, bloody, or tarry stools, or coughing up blood or vomit that looks like coffee grounds. 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.

Switch to professional interaction data

Moderate

pseudoephedrine food

Applies to: Sudafed 12 Hour Pressure+Pain (naproxen / pseudoephedrine)

Consumer information for this interaction is not currently available.

MONITOR: Coadministration of two or more sympathomimetic agents may increase the risk of adverse effects such as nervousness, irritability, and increased heart rate. Central nervous system (CNS) stimulants, particularly amphetamines, can potentiate the adrenergic response to vasopressors and other sympathomimetic agents. Additive increases in blood pressure and heart rate may occur due to enhanced peripheral sympathetic activity.

MANAGEMENT: Caution is advised if two or more sympathomimetic agents are coadministered. Pulse and blood pressure should be closely monitored.
