Read the Medication Guide provided by your pharmacist before you start using bupropion and each time you get a refill. If you have any questions, ask your doctor or pharmacist. Take this medication by mouth with or without food as directed by your doctor, usually twice a day. If you have stomach upset, you may take this medication with or after a meal or snack. Take the first dose as soon as you wake up in the morning and the second dose at least 8 hours later, or take as directed by your doctor. Taking this medication late in the day may cause trouble sleeping (insomnia). Take this medication regularly to get the most benefit from it. To help you remember, take it at the same times each day. Do not crush or chew this medication. Doing so can release all of the drug at once, increasing the risk of side effects. Also, do not split the tablets unless they have a score line and your doctor or pharmacist tells you to do so. Swallow the whole or split tablet without crushing or chewing. The dosage is based on your medical condition, liver function, and response to treatment. To reduce your risk of side effects, your doctor may direct you to start this medication at a low dose and gradually increase your dose. Do not increase your dose or use this drug more often or for longer than prescribed. Your condition will not improve any faster and your risk of side effects will increase. Do not stop taking this medication without consulting your doctor. Your dose may need to be gradually decreased. It may take 4 weeks or longer before you get the full benefit of this drug. Tell your doctor if your condition does not improve or if it worsens.
