How many mg in a baby aspirin?

How many milligrams are in a baby aspirin?

“Baby aspirin” usually refers to low-dose aspirin tablets that contain 81 mg of aspirin (sometimes marketed as 75–81 mg depending on the country and manufacturer).

Are all “baby aspirin” doses the same?

Most commonly, yes: “baby aspirin” is 81 mg. Some products may be labeled at 75 mg, but they’re still considered low-dose for the same typical use (for example, for heart-related prevention in adults).

What if a label says a different amount?

Check the bottle’s “aspirin per tablet” or “each tablet contains” line. If it lists something other than 75–81 mg (such as 100 mg or 325 mg), that product is not the standard “baby aspirin” dose.
