How many times a day should I take aspirin?



Aspirin is used by mouth and is taken differently for different purposes. If fever or pain persists, aspirin tablets may be repeated at intervals of 4 to 6 hours, but should not be taken more than four times in 24 hours. If used for antiplatelet therapy, once daily for long-term maintenance.

Aspirin inhibits prostaglandin synthesis, has antipyretic and analgesic effects, and can be used to relieve mild to moderate pain such as headache, toothache, muscle pain, menstrual cramps, and fever caused by the common or influenza.

For the treatment of fever or when pain persists, the oral dose is 1 to 2 tablets at a time for children and adults over 14 years of age, 1 tablet at a time for children 8 to 14 years of age, and 0.5 tablets at a time for children 4 to 8 years of age.

When used for antiplatelet therapy such as coronary artery disease, unless contraindicated, all patients with unstable angina or non-ST-segment elevation myocardial infarction should be given aspirin as early as possible, with the first oral dose of 300 mg in a non-intestinal or chewable intestinal formulation, followed by 75-100 mg once daily for long-term maintenance.

The more common adverse reactions include gastrointestinal reactions such as epigastric discomfort or pain, nausea, and vomiting, and gastrointestinal bleeding or ulceration, dyspnea, rash, and hepatic impairment may also occur. Contraindicated in pregnant women, lactating women, hemophilia or thrombocytopenia, hypersensitivity to aspirin and other antipyretic analgesics.

Elderly and infirm patients should be used under the guidance of a physician, if you are using other drugs, you should consult a physician or pharmacist before using the drug, if you take an overdose or serious adverse reactions, you should immediately seek medical attention.
