Table of contents:

Wellbutrin SR is an antidepressant medication used to treat major depressive disorder and seasonal affective disorder. It Wellbutrin SR is also FDA-approved to help people quit smoking. It contains the active ingredient bupropion hydrochloride.

Wellbutrin SR works by blocking the reuptake of the neurotransmitters norepinephrine and dopamine in the brain. By doing so, it increases the levels of these neurotransmitters, which can improve mood and reduce symptoms of depression. It is sometimes also prescribed to help people quit smoking or treat attention deficit hyperactivity disorder (ADHD).

Bupropion comes in the form of an SR tablet and is typically taken twice daily, with the dosage based on individual factors such as medical condition, liver function, and response to treatment. Follow the dosage and usage instructions provided by the doctor to reduce the risk of side effects and ensure the medication is effective.

Uses and Dosage

Wellbutrin SR comes in the form of an SR tablet and should be taken by mouth with or without food as directed by your doctor, typically twice a day. If the medication causes stomach upset, it may be taken with food or after a meal/snack. The tablets should be swallowed whole and should not be crushed or chewed, as doing so could release all the drug at once, increasing the risk of side effects.

The first dose should be taken in the morning as soon as the patient wakes up, and the second dose should be taken at least 8 hours later or as directed by the doctor. Taking Wellbutrin SR late in the day may cause insomnia. Take Wellbutrin SR regularly to obtain the most benefit from it. To aid in remembering, it should be taken at the same time each day.

The dosage of Wellbutrin SR is individualized based on the patient's medical condition, liver function, and response to treatment. To reduce the risk of side effects, the doctor may direct the patient to begin taking the medication at a low dose and gradually increase it. The usual adult target dose for Wellbutrin SR is 300 mg per day, given as 150 mg twice daily. The initial dosing is typically 150 mg per day given as a single daily dose, and then the dose may be increased gradually to the target dose. However, the dosage of Wellbutrin SR is individualized based on the patient's medical condition, liver function, and response to treatment.

The dose should not be increased or taken more frequently or for a longer duration than prescribed. Doing so will not improve the patient's condition any faster and will increase the risk of side effects. Patients should not stop taking Wellbutrin SR without consulting their doctor. The dose may need to be gradually decreased. It may take up to 4 weeks or longer before patients experience the full benefits of Wellbutrin SR.
