Medication effects
Some medications can increase bleeding risk or affect platelet function. Examples include aspirin, certain anti-inflammatory medicines such as ibuprofen, anticoagulants, and some other prescription drugs.
Certain antibiotics and other medications may also be associated with low platelet counts or skin reactions in some people.
The connection depends on the particular medicine, dose, medical history, and timing. Do not stop a prescribed blood thinner or another essential medication without professional advice. If a new rash develops after starting or changing a medication, contact a healthcare professional promptly.
Low platelet counts or clotting problems
Platelets help the blood form clots and stop bleeding. When platelet levels are too low or their function is impaired, tiny blood vessels may leak more easily.
Possible clues include unexplained bruising, frequent nosebleeds, bleeding gums, or unusually heavy bleeding. Some people, however, may initially notice only skin changes.
Blood-clotting disorders and certain other blood conditions can also produce petechiae or purpura. A medical assessment and, when appropriate, blood tests are needed to investigate these possibilities.
