Zyban (Buproprion Hydrochloride)

Dosage

This medication should be taken orally following the instructions of your healthcare provider. It can be taken with or without food and is usually taken twice daily. Doses should be taken at least eight hours apart to prevent seizures. Do not crush, chew, or dissolve this medication before taking it, as this can release all the drug at once, increasing the risk of side effects. Only split the tablet if they have a score line and you have been instructed to do so by your doctor. Dosage is assessed based on the severity of your condition and your response to treatment. Your doctor may want to gradually increase your dose to minimize side effects. Do not take more or less of the medication or more or less frequently than prescribed. Excessive bupropion intake is associated with developing seizures. Do not be alarmed if an empty tablet shell appears in your stool. This is harmless and normal.
