Mental Health Home > Bupropion SR Dosing
The recommended starting bupropion SR dosage for both depression treatment and smoking cessation is 150 mg once daily in the morning. A few of the factors that can affect bupropion SR dosages include your age, other drugs you may be taking, and other medical conditions you may have. Talk with your healthcare provider, nurse, or pharmacist if you are unsure about anything related to your dosage or bupropion SR dosing in general.
Bupropion SR Dosing: An IntroductionThe dose of bupropion SR (Wellbutrin SR® or Zyban®) your healthcare provider prescribes will vary depending on a number of factors, including:
- Whether you are taking it for depression or smoking cessation
- Your age
- Other medical conditions you may have
- Other medications you may be currently taking.
As always, do not adjust your bupropion SR dosage unless your healthcare provider specifically instructs you to do so.
Bupropion SR Dosage for Depression
The recommended starting bupropion SR dose for the treatment of depression is bupropion SR 150 mg once daily in the morning. As soon as the fourth day, your healthcare provider may increase your dose to bupropion SR 150 mg twice daily. To help avoid seizures, each individual dose should not exceed 200 mg, and you should not take more than 400 mg total per day. Also, your healthcare provider should increase your dose slowly.
Bupropion SR Dosage for Smoking Cessation
The recommended starting bupropion SR dose for stopping smoking is bupropion SR 150 mg once daily in the morning. As soon as the fourth day, your healthcare provider may increase your dose to bupropion SR 150 mg twice daily. You should start taking bupropion SR while you are still smoking, because it takes about a week to build up the level of bupropion SR in your blood. You and your healthcare provider should choose a "quit date," usually sometime in the second week that you are taking bupropion SR.
You should take bupropion SR for at least 7 weeks to 12 weeks. If you have not made any progress toward quitting by the seventh week, your healthcare provider may decide to take you off bupropion SR. However, if you have successfully stopped smoking, your healthcare provider may decide to keep you on bupropion SR for several months, as bupropion SR can help you from starting smoking again.
