Calculate appropriate aspirin doses for different purposes
This calculator is for educational purposes only. Daily aspirin therapy for heart protection should only be started after consulting with your doctor. Aspirin has significant bleeding risks. Never give aspirin to children or teenagers with viral illness.
The US Preventive Services Task Force (2022) recommends:
Aspirin use in children and teenagers with viral infections (flu, chickenpox, cold) is linked to Reye's syndrome, a rare but potentially fatal condition affecting the brain and liver.
This is a decision to make with your doctor. For most people without existing heart disease, the bleeding risks may outweigh the benefits, especially for those over 60 or with bleeding risk factors. Those who have had a heart attack or stroke usually benefit from daily aspirin.
Both are NSAIDs that reduce pain, fever, and inflammation. Aspirin has unique blood-thinning effects useful for heart protection but also increases bleeding risk. Ibuprofen is often preferred for pain due to fewer GI side effects. If you take daily aspirin for your heart, take it at least 30 minutes before ibuprofen.
NO - aspirin should NOT be given to children or teenagers (under 19) with viral illness due to the risk of Reye's syndrome. The only exception is for specific medical conditions like Kawasaki disease, which is treated in a hospital setting.
Typically yes - aspirin is usually stopped 7-10 days before elective surgery to reduce bleeding risk. However, this depends on your reason for taking aspirin and the type of surgery. Always follow your surgeon's and cardiologist's specific instructions.
Take it as soon as you remember, unless it's almost time for your next dose. Don't double up. Missing one dose is unlikely to cause problems, but try to take it consistently. Some people set a daily alarm or keep aspirin with their toothbrush.
Combining aspirin and alcohol significantly increases the risk of stomach bleeding. If you take daily aspirin and drink alcohol, limit consumption and be aware of increased risk. Avoid aspirin for hangover headaches - use acetaminophen sparingly or ibuprofen if needed.
