What is the correct adult aspirin dose for a suspected cardiac event and how should it be administered?

When a cardiac event is suspected, aspirin is given to rapidly inhibit platelet clumping and help limit thrombus growth. The effective adult dose is 162–325 mg total, and chewing the tablet speeds how quickly it works. Therefore you can give either two chewable 81 mg tablets (total 162 mg) or a single 325 mg tablet, with the patient chewing the tablet before swallowing the chewed material. This chewing step is key to faster absorption and quicker antiplatelet effect. If there are contraindications like an aspirin allergy or active GI bleeding, do not administer.
