Can antidepressants cause internal bleeding?

If you’re on antidepressants, or are considering taking them, it’s worth examining some of the risks. That’s because selective serotonin reuptake inhibitors (SSRIs), one of the most widely prescribed classes of drugs to treat depression, have been found to carry a significantly increased risk of internal bleeding.

Can antidepressants cause bleeding?

Researchers say the risk of bleeding associated with antidepressants is due to the brain chemical serotonin, a chemical messenger that plays a role in depression and anxiety. Most antidepressants affect serotonin.

Do SSRIs cause gastrointestinal bleeding?

Being over the age of 80 or having a previous history of GI bleeding adds to the risk of upper GI bleeding with SSRIs. The risk may also be higher in patients who have just started taking SSRIs, and in those taking SSRIs with a high/intermediate affinity for the serotonin receptor.

What organs are affected by antidepressants?

It’s widely known that brain serotonin affects mood, and that most commonly used antidepressant treatment for depression blocks the absorption of serotonin by neurons. It is less widely known, though, that all the major organs of the body — the heart, kidneys, lungs, liver — use serotonin from the bloodstream.

How does serotonin affect bleeding?

How does serotonin cause bleeding?

SSRIs inhibit the serotonin transporter, which is responsible for the uptake of serotonin into platelets. It could thus be predicted that SSRIs would deplete platelet serotonin, leading to a reduced ability to form clots and a subsequent increase in the risk of bleeding.

Which antidepressant does not increase risk of bleeding?

Antidepressants with low or no affinity for the serotonin transporter, such as bupropion or mirtazapine, may be appropriate alternatives for patients at risk of bleeding.
