Wellbutrin SR may be prescribed for depression and seasonal affective disorder. It may also be used to reduce withdrawal symptoms in those quitting smoking.

Wellbutrin contains bupropion hydrochloride, an effective antidepressant that works by increasing dopamine and norepinephrine in the brain. The "SR" in the name indicates that this is the sustain-release version of Wellbutrin.

Your doctor will prescribe the dosage strength that is best suited for your treatment. Below are the general recommended doses for each condition. 

Depression

The recommended starting dose for depression is 150 mg of Wellbutrin SR daily. You will want to take this as a single dose, preferably in the morning. Based on your response to treatment, your doctor may increase your dosage to 450 mg per day. 

Seasonal affective disorder (SAD)

The starting dose for SAD is 150 mg per day. If necessary, your doctor may increase your dosage strength to 300 mg daily. If you require 300 mg daily, your doctor may have you take two 150 mg pills per day so that the dose is divided. 

Smoking Withdrawal Symptoms

A once-daily dose of 150 mg is the usual starting point for those quitting smoking. As with the previous two conditions, it is recommended that you take your daily dose in the morning. The maximum dosage for smoking cessation is 300 mg per day or as instructed by your doctor.

Your Wellbutrin SR dose may be adjusted over time by your healthcare provider. Never take more than you have been prescribed, or serious side effects may occur. If you are experiencing bothersome side effects, speak to your doctor about changing your dose as needed.
