Antiplatelets, low-dose aspirin - Side effects 

Side effects of aspirin 

Aspirin can cause side effects, although serious reactions are rare.

See your doctor if you are worried or continue to experience any side effects while taking low-dose aspirin.

Common side effects may include: 

However, less than 10% of people taking aspirin experience these side effects. If you experience indigestion, try sticking to basic food and taking your aspirin after a meal.

Allergic reaction

In some cases aspirin can cause an allergic reaction, although this is more common in people who have asthma. Go to the nearest hospital's accident and emergency department (A&E) if you experience:

  • swelling of the lips, mouth or throat
  • breathing problems
  • a skin rash which appears quickly

Uncommon or rare side effects

Other, rarer side effects of aspirin may include:

  • a runny nose
  • headache
  • ringing in the ears (tinnitus)
  • vertigo
  • a raised, itchy rash on the skin (hives)
  • nausea or vomiting
  • worsening of asthma caused by narrowing of airways
  • inflammation (swelling) of the stomach
  • bleeding in the stomach
  • bruising

In extremely rare cases, a possible side effect of taking low-dose aspirin is haemorrhagic stroke (bleeding in the brain).

Reporting side effects

The Yellow Card Scheme allows you to report suspected side effects from any type of medicine you are taking.

It is run by a medicines safety watchdog called the Medicines and Healthcare products Regulatory Agency (MHRA). See the website of the Yellow Card Scheme for more information.
