Reduces the risk of heart attacks

Taking a low daily dose of aspirin can reduce the risk of heart attacks, as aspirin prevents platelets from clumping together inside blood vessels. Large clots can block vessels and restrict blood flow.

Lowers cancer risk

Regular aspirin use may reduce the risk of certain types of cancer, such as liver, ovarian, and colorectal cancer. This is because aspirin blocks cyclooxygenase (COX) enzymes, which are naturally produced by the body as well as by some precancerous tissues.

Should not be taken with blood pressure medications

Aspirin blocks the production of prostaglandins. Blood pressure medications, on the other hand, work by increasing prostaglandin levels. Taking both together can cancel out their effects and, in some individuals, may cause kidney problems.

Prostaglandins are active substances that affect many bodily processes even in small amounts. They play an important role in cardiovascular function, inflammation, immune response, reproductive health, and hormonal regulation.

May cause Reye’s syndrome

Children who take aspirin are at increased risk of developing Reye’s syndrome — a rare condition characterized by sudden brain damage and liver problems. It is often accompanied by vomiting, confusion, and seizures. The syndrome has occurred in children who were given aspirin while recovering from the flu or chickenpox.

Can cause ringing in the ears

Salicylic acid — a breakdown product of aspirin’s main ingredient — may damage the inner ear. Therefore, high doses of aspirin can cause ringing in the ears (tinnitus). This usually subsides once the medication is stopped.

Is not safe during pregnancy

Aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs) are not recommended during pregnancy, especially in the third trimester. Because aspirin affects blood clotting, it can increase the risk of bleeding for both mother and baby.

May benefit brain health

Studies show that people who take aspirin regularly may have a lower risk of developing Alzheimer’s disease. This is likely because aspirin prevents blood clots and improves blood flow to the brain.

Interacts poorly with many medications

Research shows that aspirin interacts with many other medications, including antidepressants, antacids, blood thinners, diabetes medications (such as insulin), and pain relievers (like ibuprofen and corticosteroids). Aspirin may affect the metabolism of these medications in the liver, altering their effectiveness or blood levels — potentially reducing their therapeutic effect or increasing toxicity.

Remember: Never take aspirin without a doctor’s prescription.
