Can medications and supplements contribute to easy bruising?

Aspirin, anticoagulant medications and anti-platelet agents reduce your blood's ability to clot. Antibiotics might also be associated with clotting problems. As a result, bleeding from capillary damage might take longer than usual to stop — which allows enough blood to leak out to cause a bigger bruise.

Topical and systemic corticosteroids — which can be used to treat various conditions, including allergies, asthma and eczema — cause your skin to thin, making it easier to bruise. Certain dietary supplements, such as ginkgo, also can increase your bruising risk due to a blood-thinning effect.

If you experience increased bruising, don't stop taking your medications. Talk to your doctor about your concerns. Also, make sure your doctor is aware of any supplements you're taking — especially if you're taking them while on a blood-thinning drug. Your doctor might recommend avoiding certain over-the-counter medications or supplements.
