PATIENT INFORMATION LEAFLET FOR

ASPIRIN 300MG TABLETS

You should let your doctor know you are taking aspirin
tablets, particularly if you are going to have an operation,
as you may need to stop taking your tablets several days
before the operation.
Your blood, kidney and liver should be monitored during
prolonged use of aspirin as blood, kidney and liver
disorders may develop.

1. WHAT ASPIRIN 300MG TABLETS ARE AND WHAT THEY
ARE USED FOR
Your medicine is called Aspirin 300mg Tablets (called
Aspirin Tablets throughout the rest of this leaflet).
What this medicine does
Aspirin Tablets are used for the symptomatic relief of mild
to moderate pain, including migraine, toothache, neuralgia,
headache, sore throat, period pains, aches and pains
(including muscle pains and backache). For the
symptomatic relief of influenza, feverishness and feverish
colds. For the symptomatic relief of sprains, strains,
rheumatic pain, sciatica, lumbago, fibrositis, joint swelling
and stiffness.
Aspirin belongs to a group of medicines called
non-steroidal anti-inflammatory drugs (NSAIDs). Aspirin
works by preventing the release in the body of substances
which cause pain, inflammation and fever.
2. BEFORE YOU TAKE ASPIRIN TABLETS
There is a possible association between aspirin and
Reye’s Syndrome when given to children. Reye’s
syndrome is a very rare disease, which can be fatal. For
this reason aspirin should not be given to children aged
under 16 years, unless on the advice of a doctor.
Do not take Aspirin Tablets if you:
• are allergic (hypersensitive) to aspirin or other
non-steroidal anti-inflammatory drugs (NSAIDs) e.g.
ibuprofen, or any of the other ingredients of Aspirin
Tablets (see Section 6 What Aspirin Tablets contain).
Symptoms may include rhinitis (runny nose), swollen
face, mouth or tongue, itchy rash or asthma attack;
• have or have had a stomach ulcer;
• have a condition where your blood does not clot
properly (e.g. haemophilia);
• are taking medicines to thin your blood such as warfarin;
• have or have had gout;
• are in the last 3 months of pregnancy or are
breast-feeding.
Talk to your doctor or pharmacist if any of the following
apply to you:
• if you have asthma, or suffer from allergies;
• if you have problems with your heart, kidneys or liver;
• if you are dehydrated;
• if you have nasal polyps (inflamed swellings inside the
nose)
• if you suffer from indigestion (dyspepsia)

Using other medicines
Make sure your doctor knows if you are taking a medicine
listed here:

• Mifepristone (used to terminate pregnancy). You should
not take aspirin until eight to twelve days after
mifepristone. If taken with aspirin this medicine may
not be as effective.
• Non-steroidal anti-inflammatory (NSAIDs) e.g.
ibuprofen or diclofenac sodium (used for pain relief and
to treat inflammation)or Corticosteroids e.g.
prednisolone and betamethasone (used to treat allergy
or inflammation): if taken with aspirin you may have
more severe side effects e.g. increased risk of bleeding
or ulcers in the stomach. If you suddenly stop taking
corticosteroids you may develop aspirin poisoning.
• Metoclopramide (used to treat nausea and vomiting): it
may increase the effect of aspirin.
• Adsorbents e.g. kaolin (for diarrhoea) and Antacids e.g.
aluminium hydroxide and magnesium carbonate (used

effect of aspirin.
• Medicines known to affect the clotting of your blood: if
you take one of these medicines below with aspirin you
may increase the likelihood of bleeding.

(blood thinning medicines), streptokinase.

treat high blood pressure.

these medicines may not be as effective and you may
suffer from kidney problems.
• Antidepressants (used to treat depression) e.g.
Selective Serotonin Re-uptake Inhibitors (SSRIs) (such
as venlafaxine): if taken with aspirin you may increase
the likelihood of bleeding.
• Medicines to control epilepsy e.g. phenytoin and
valproate: aspirin may increase the effect of these
medicines. If you take sodium valproate with aspirin you
may increase the likelihood of bleeding.
• Zafirlukast (used to prevent or treat asthma).
• Spironolactone (diuretic) water tablets, Probenicid or
Sulfinpyrazone (used to treat gout): if taken with aspirin
these medicines may not be as effective.

disease and cancer) or Carbonic anhydrase inhibitors
e.g. acetazolamide (used in the treatment of glaucoma,
