Wellbutrin SR is a prescription medicine indicated for the treatment of depression. 

As an antidepressant, Wellbutrin SR works by rebalancing specific natural brain chemicals (dopamine and norepinephrine) to enhance mood and overall well-being. 

Uses and Dosage 

Before taking Wellbutrin SR and with every prescription refill, carefully review the available medication guide and patient information leaflet. For any inquiries or concerns, do not hesitate to consult with your healthcare provider or pharmacist. 

The dosage of Wellbutrin SR is individualized according to the patient’s medical condition, liver function, and treatment response. 

To mitigate potential side effects, your doctor may recommend starting this medication with a conservative dose and progressively titrating it upwards.  

Typically, Wellbutrin SR is taken twice daily, with the first dose upon awakening in the morning and the second dose after a minimum of 8 hours, or as instructed by the doctor. 

Ingest the tablets whole, without crushing or chewing, to prevent the rapid release of the medication, which can elevate the risk of side effects. 

This medication may be taken with or without food, but if you experience stomach upset, consider taking it with or after a meal or snack. 

For optimal results, take Wellbutrin SR regularly at the same time of the day daily. 

Adhere to the prescribed dosage regimen and avoid self-adjusting by increasing the dose or using the drug more frequently or for a prolonged period, as this will not hasten your recovery and may heighten the risk of side effects. 

Consult your doctor before discontinuing Wellbutrin SR, as a gradual dose reduction may be necessary.
