What is the dosage for baby aspirin?

A dosage of 81 milligrams is the normal dosage for baby aspirin, according to WebMD. This dosage is often recommended for heart health in an ongoing aspirin regimen.

Doses higher than 81 milligrams are not any better for heart health than the 81-milligram, baby-aspirin dose, according to WebMD. In fact, higher dosages may increase the risk of stomach bleeding. Studies have shown that while aspirin prevents blood clots, which is the benefit of aspirin therapy, it does increase the tendency for bleeding in the gastrointestinal tract. Therefore, most doctors now recommend the low-dose baby aspirin, which is around one-quarter of the traditional 325-milligram adult dose.
