It's possible for drugs that affect serotonin to cause bruising, and while not rare, it's not that common for it to be a real problem.
Serotonin is used in platelet aggregation for normal clotting. SSRIs (& even though Effexor is not strictly an SSRI, it does affect serotonin too) can impair the ability of platelets clumping which can lead to longer clotting times - hence bruising.
Not all bruising is worrisome unless you're bruising very easily from light pressure or if you notice cuts won't clot properly. It also can be a problem if you have bad ulcers. If you're concerned, a doctor can perform a clotting time test to be sure.
