How to Buy Bupropion Online in the UK and Internationally – IR, SR & XL Formulations Available
If you’re looking to buy Bupropion online in the UK, or need access to Immediate Release (IR), Sustained Release (SR), or Extended Release (XL) formulations from countries like Australia, Japan, or Switzerland, you’re not alone. Many people face challenges accessing Bupropion locally due to availability issues or cost. At International Pharmacy, we offer a trusted solution for international access to all three Bupropion formulations.

What Is Bupropion?
Bupropion is a prescription medication primarily used to treat major depressive disorder (MDD) and seasonal affective disorder (SAD). It is also effective for smoking cessation. Bupropion works differently from other antidepressants by targeting norepinephrine and dopamine, making it a valuable option for patients who may not respond to SSRIs.
Bupropion Formulations: IR, SR & XL
Bupropion is available in three main formulations. Each differs in how the medication is released and how often it must be taken:
- Bupropion Tablets (Immediate Release) – The IR version is taken three times per day. It delivers the active ingredient quickly but may cause more noticeable side effects like nausea or insomnia due to rapid absorption.
- Bupropion SR (Sustained Release) – The SR form is typically taken twice daily. It provides a smoother release over 12 hours, improving tolerability while remaining effective.
- Bupropion XL (Extended Release) – This version offers once-daily dosing, releasing the medication steadily over 24 hours. XL is commonly preferred for its convenience and consistent therapeutic levels.
Your doctor will recommend the formulation best suited to your health needs and lifestyle. Some patients start on IR and transition to SR or XL depending on response and side effect profile.

How to Take Bupropion
Always take Bupropion exactly as prescribed by your healthcare provider. Here are some general guidelines:
- Do not crush, chew, or split the tablets, especially SR or XL versions, as this can alter the release mechanism and increase the risk of side effects.
- Take doses with water at the same time each day.
- If you miss a dose, skip it and take your next dose at the scheduled time. Do not double up.
Potential Side Effects
- Common side effects may include:
- Dry mouth
- Insomnia
- Nausea
- Headache
- Anxiety or agitation
- These often subside as your body adjusts. Rarely, Bupropion may increase the risk of seizures, particularly at higher doses or if combined with alcohol.
Safety and Precautions
Before starting Bupropion, inform your doctor if you have:
- A history of seizures
- An eating disorder (e.g., bulimia, anorexia)
- A history of alcohol or drug dependence
Avoid alcohol while taking Bupropion. Do not start Bupropion if you’ve taken an MAO inhibitor in the last 14 days.
Why is Wellbutrin (Bupropion) not available in the UK on the NHS?
It’s not actually quite that clear cut. There have been supply issues for various reasons, but we have no problems with supply and can deliver Wellbutrin (Bupropion) to your UK address. Additionally, when you access smoking cessation help on the NHS, other options are typically tried first. You may have tried these options already, but unless your GP has a record of them, you may need to go through various additional steps before they will prescribe medication.
