Which condition is NOT a contraindication for Aspirin use?

The choice identifying pregnancy as not being a contraindication for aspirin use is accurate because, while it requires careful consideration, aspirin can be prescribed during pregnancy in certain situations. Specifically, low-dose aspirin therapy is sometimes recommended to reduce the risk of complications such as preeclampsia in women at high risk. However, the decision to use aspirin during pregnancy must always be made by a healthcare provider who weighs the potential benefits against any risks involved.

In contrast, age under 16 years is a contraindication due to the risk of Reye's syndrome, active bleeding tendencies pose an immediate risk where aspirin could exacerbate bleeding, and an allergy to aspirin would lead to severe adverse reactions that contraindicate its use altogether.
