How many mg is in a baby aspirin?

A “baby aspirin” typically refers to low-dose aspirin tablets that contain 81 milligrams (mg) of aspirin.

Are there different “baby aspirin” doses?

Yes. Some products marketed for low-dose use contain 81 mg (most common) or 162 mg (less common). The exact amount depends on the label of the specific product—checking the “mg” per tablet is the only reliable way.

What should you check on the bottle?

Look for the strength statement on the front or back label (for example, “Aspirin 81 mg”). The tablet’s listed milligrams are what matter, not the phrase “baby aspirin.”
