Some Seizure Medications
Some
seizure medications may cause your body to metabolize the hormones in
Premphase too quickly, possibly leading to low levels of Premphase in the body. Although this can increase the risk of spotting or bleeding and make Premphase less effective, it is not a dangerous drug interaction.
St. John's Wort
St. John's wort (a commonly used herbal supplement) may cause your body to metabolize the hormones in Premphase too quickly, leading to low levels of Premphase in the body. Although this can make Premphase less effective, it is not a dangerous drug interaction.
Various Antibiotics or Antifungals
Some antibiotic or antifungal medications may decrease the ability of your liver to metabolize Premphase, possibly leading to high levels of Premphase in the body. This may increase the risk of
Premphase side effects. Check with your healthcare provider before combining Premphase with certain antibiotics or antifungals.
