Asmaloc 300 SR Theophylline Carbamazepine
ModerateCarbamazepine makes the body clear Asmaloc SR (theophylline) out faster, so less of the medicine stays in your blood. The same is true for barbiturates, lithium, phenytoin, rifampicin and sulphinpyrazone. Because of this, Asmaloc SR may work less well, and your doctor may need to raise the dose.
These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.
