Is Bayer Aspirin Safe?

Generic: aspirin

Reviewed by Younghun ChoLast reviewed April 20, 2026

It depends on the individual. Bayer Aspirin is generally safe for most adults when used as directed for pain relief or fever. However, it carries significant risks, including severe stomach bleeding and a rare but serious condition called Reye's syndrome in children and teenagers.

Who Should Avoid or Consult First

  • Children and teenagers, especially those recovering from chickenpox or flu-like symptoms, due to the risk of Reye's syndrome.
  • Individuals aged 60 or older, due to an increased risk of severe stomach bleeding.
  • People with a history of stomach ulcers, bleeding problems, or known aspirin allergy.
  • Pregnant or breastfeeding women, unless specifically advised and monitored by a doctor.

Common Side Effects

  • Stomach upset, heartburn, or mild nausea — commonly reported, especially with higher doses or prolonged use.
  • Ringing in the ears (tinnitus) — typically occurs with higher doses.

Interactions to Watch For

Blood thinners (anticoagulants) or steroid drugs

Combining these with aspirin significantly increases the risk of severe stomach bleeding.

Other NSAIDs (e.g., ibuprofen, naproxen, other aspirins)

Taking multiple NSAIDs together greatly increases the risk of severe stomach bleeding.

Alcohol (3 or more drinks daily)

Regular heavy alcohol consumption while using aspirin substantially raises the risk of severe stomach bleeding.

People Also Ask

Can children take Bayer Aspirin?

No, children and teenagers should not take Bayer Aspirin, especially if they are recovering from chickenpox or flu-like symptoms. This is because aspirin can cause Reye's syndrome, a rare but very serious illness, in this age group. Always consult a doctor for pain or fever in children.

Is it safe to take aspirin daily long-term?

Long-term daily use of aspirin, even at low doses, increases the risk of stomach bleeding and ulcers. It should only be taken daily under a doctor's supervision, especially if you are over 60 or have a history of stomach problems. Your doctor can weigh the benefits against the risks for your specific health needs.

Can I drink alcohol while taking aspirin?

It is not recommended to drink alcohol, especially three or more alcoholic drinks daily, while taking aspirin. Combining alcohol with aspirin significantly increases your risk of severe stomach bleeding. If you consume alcohol, use aspirin cautiously and in moderation.

Can pregnant women take aspirin?

Generally, pregnant women should avoid taking aspirin unless specifically advised and monitored by their doctor. Aspirin, especially in the third trimester, can cause complications for both the mother and the baby. Always consult your healthcare provider before taking any medication during pregnancy.

What happens if I take too much aspirin?

Taking too much aspirin can lead to an overdose, causing symptoms like ringing in the ears, nausea, vomiting, rapid breathing, and confusion. In severe cases, it can be life-threatening. If you suspect an overdose, seek immediate medical attention or call poison control.

Bottom Line

Bayer Aspirin is an effective pain reliever for adults, but it's crucial to be aware of its serious risks, particularly stomach bleeding and the absolute contraindication for children and teenagers. Always read the label carefully and consult a healthcare professional if you have underlying health conditions or take other medications.
