Is it safe to take one adult aspirin a day if i have pain? my doc told me it was safe as long as i "tolerated" it well.

Yes, maybe: An Aspirin a day can benefit men over the long run to decrease heart disease. In women, long term usage is less effective. If you take a lot of aspirin, it may cause GI irritation and actually bleeding. Thus, make sure you take it with food to help decrease this.

Asa: Usually one Aspirin is safe though there are occasional bleeds with this dose.
