Beyaz Drug Interactions

Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)
Taking Beyaz with NSAIDs can increase the risk of high potassium levels in your blood (hyperkalemia). Occasional use of NSAIDs in healthy women who take Beyaz should not typically cause a problem. However, check with your healthcare provider if you take NSAIDs regularly or if you take a large NSAID dosage.
Phenytoin and Fosphenytoin
The folate in Beyaz could decrease the effectiveness of phenytoin, increasing the risk of seizures. However, high doses of folate are often recommended for people taking phenytoin, since phenytoin decreases folate levels, especially during pregnancy. Your healthcare provider should monitor the level of phenytoin in your blood and adjust your dosage as necessary if you take Beyaz.
Potassium Products
Combining Beyaz with potassium products can increase the risk of high potassium levels in your blood (hyperkalemia). Your healthcare provider should regularly check your potassium levels if you are using potassium products while taking Beyaz.
Potassium-Sparing Diuretics
Combining Beyaz with a potassium-sparing diuretic can increase the risk of high potassium levels in your blood (hyperkalemia). Your healthcare provider should regularly check your potassium levels if you are taking both of these medications.
Protease Inhibitors
Using Beyaz with a protease inhibitor may increase your risk of pregnancy and can make the protease inhibitor less effective. Talk with your healthcare provider before combining these two medications.
Pyrimethamine
The folate in Beyaz may decrease the effectiveness of pyrimethamine for treating certain parasitic infections. This does not seem to be a problem when treating malaria. However, it is best to check with your healthcare provider before combining pyrimethamine with Beyaz.
