Why this happens

Aspirin is a blood thinner (antiplatelet) that prevents blood from clotting easily. Dysport is injected into the muscle using a needle. Because aspirin thins the blood, any tiny blood vessels nicked during the injection are more likely to leak, leading to a bruise or a small haematoma (a collection of blood under the skin).

If you are taking aspirin for a specific medical condition (such as heart disease or stroke prevention), do NOT stop taking it without talking to your doctor first. If you are taking aspirin for general pain relief, consider switching to paracetamol. Most practitioners recommend avoiding aspirin for 7 to 10 days before a Dysport treatment to minimise bruising. Always inform the person performing your injection that you are taking aspirin.
