What is the difference between baby aspirin and normal aspirin?

Dose. Babies should not be given aspirin the so called "baby aspirin" is a 65 mg tablet. Regular Aspirin is anywhere from 325 to 1000 mg.
Product use. The term "baby" aspirin is archaic but lingers because of years of use.We rarely recommend aspirin for anyone under 16 yrs since the late 70's when it was linked with liver failure & death.When used in adults the anti-inflammatory dose requires multiples of the regular 325 mg tablet. If used to reduce platelet adhesion (MI,Stroke) they found the "baby" aspirin size is all they need.
