Does bupropion thin your blood? (5+ precautions)

In this article, we will explore whether bupropion is associated with blood thinning or not, what research studies suggest on this, precautionary measures before considering bupropion and potential interactions between bupropion and blood thinners. 

Does bupropion thin your blood?

Yes, bupropion may cause thinning of blood in some individuals. People with a history of bleeding disorders are at higher risk of experiencing this side effect. (1)

Bupropion is a medication used primarily as an antidepressant, it works by affecting the balance of certain neurotransmitters in the brain. It can have side effects that affect bleeding. (1)

It is essential to have a thorough discussion with your healthcare provider about your medical history, including any bleeding disorders or medications you may be taking that affect blood clotting. 

What is the connection between bupropion and blood thinning?

Bupropion does not have any direct relationship with blood thinning. However, like many medications, bupropion can have side effects, and in some cases, it increases the risk of bleeding or bruising. (2)

The connection between bupropion and blood thinning is indirect, individuals with a history of bleeding disorders or those taking other medications that affect blood clotting should use caution and discuss their circumstances with their healthcare provider before using bupropion. (2)

What does research suggest?

Research studies suggest that bupropion and some other antidepressants may potentially lead to blood-thinning effects as a side effect. These medications might interfere with the ability of blood platelets to stick together and form clots. (2)

However, there is limited scientific evidence regarding the bupropion dosage and its impact on blood clotting. If persistent bleeding occurs, it may be necessary to reduce the dose of bupropion or discontinue its use. 

What precautions should be taken before using bupropion?

Here are some key precautions to consider before taking bupropion: (3)

Consult with a healthcare provider: Always take bupropion under the supervision and guidance of a healthcare provider who can asses your individual needs and monitor your progress. 

Medical history: Inform your healthcare provider about your complete medical history, including any pre-existing medical conditions, allergies, medications you are taking and any history of seizures. 

Dosage: Take the prescribed dose as directed by your healthcare provider. Do not increase or decrease the dose without consulting them. 

Timing: Follow the recommended dosing schedule and take bupropion at the same time each day, as directed.

Extended-Release Formulation: If you are taking an extended-release formulation, do not crush, chew or split the tablets, as this can affect the medication’s release. 

Side effects: Be aware of the potential side effects and report any unusual or severe reactions to your healthcare provider.

Interactions: Inform your healthcare provider of all the medications, supplements or herbal products you are taking, to prevent potentially harmful interactions. 

Alcohol and substance use: Limit or avoid alcohol while taking bupropion, as it may increase the risk of seizures and other side effects.

What to do if you experience blood thinning with bupropion?

If you are experiencing signs of blood thinning, such as unusual bleeding or bruising while taking bupropion (Wellbutrin), contact your healthcare provider immediately. (3,4)

Do not adjust medication on your own. Your doctor may conduct a medical evaluation and may adjust your treatment plan or explore alternative medications depending on the severity of your symptoms. Your doctor may recommend regular monitoring to track your progress and assess whether the bleeding issues are improving. (4)


In this article, we have discussed the blood-thinning effects of bupropion and have also discussed the precautionary measures for overcoming or preventing this side effect.

In my opinion, you must be vigilant about any side effects while using bupropion, especially if you are taking other blood-thinning agents like, Warfarin, aspirin or NSAIDs. 

Open and transparent communication with your healthcare provider is key to ensuring the best outcomes when using bupropion. They can provide personalized guidance, make adjustments as needed, and closely monitor any side effects.
