To treat pain or fever in adults, the recommended dose is 325 mg to 650 mg every 4 to 6 hours as needed. The maximum daily dose is 4,000 mg, unless otherwise directed by your doctor. For adults with conditions caused by inflammation such as rheumatoid arthritis,the usual dose is 975 mg 4 to 6 times daily on a regular basis. Sometimes, higher doses may be used. To treat migraine headache pain, the recommended adult dose is 1,000 mg at the onset of pain or symptoms.
To prevent a first nonfatal heart attack, TIA, a second heart attack, or a second stroke, the usual dose for adults is 80 mg to 325 mg once daily, depending on your doctor’s instructions. During a heart attack, the recommended ASA dose is 160 mg to 162. 5 mg chewed or crushed. As soon as you suspect you are having a heart attack, call an ambulance and take the recommended ASA dose, providing you have no allergies or other conditions or factors that would indicate ASA is not right for you.
To prevent blood clots after total hip replacement surgery, the recommended dose is 650 mg twice a day started one day before surgery and continued for 14 days after surgery unless otherwise directed by your doctor. For rheumatic fever, the usual dose of ASA is 80 mg per kilogram of body weight per day in divided doses. Children’s dosage: This medication is not recommended to be used by children, teenagers, or young adults to treat fever (see the section, “Are there any other precautions or warnings for this medication? “).
However, if recommended by a doctor in other circumstances such as to treat pain, the recommended dose is 10 mg to 15 mg per kilogram of body weight every 6 hours as needed to a maximum of 2,400 mg per day (ask your doctor or pharmacist to give you the correct dose if you are unsure). When used as an anti-inflammatory, the recommended dose is 60 mg to 125 mg per kilogram of body weight daily in 4 to 6 divided doses. Because ASA can cause stomach irritation and upset, specially coated tablets called enteric-coated are recommended when taking ASA for long periods of time.
This special coating prevents the tablet from dissolving until it has passed the stomach and moved into the small intestine. This coating also means that it will take longer for the medication to take effect, so do not use enteric-coated tablets when fast relief is required. ASA should also be taken with food to prevent stomach upset. Enteric-coated medications can be taken without food. Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications.
If your doctor has recommended a dose different from the ones listed here, do not change the way you are taking the medication without talking to your doctor. It is important to use this medication exactly as prescribed by your doctor. If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one.

In your blood there are ‘sticky’ cells called platelets. When you cut yourself, the platelets stick to each other (clot) to seal the wound. Sometimes platelets stick to each other inside a blood vessel – this is called a thrombus. A thrombus can block a blood vessel, and this is often the cause of a stroke or heart attack. This is more likely to happen if you have thickening of your arteries, which can occur if you have cardiovascular (heart and blood vessel) disease. Aspirin reduces the stickiness of platelets. This helps to prevent a thrombus from forming and reduces the risk of having a heart attack or stroke.
When aspirin is used in this way, it is often referred to as ‘low-dose’ aspirin. Low-dose aspirin is particularly useful for people with heart or blood vessel disease, such as angina, peripheral vascular disease, transient ischaemic attack (TIA), and people who have had heart bypass surgery. Also, most people who have recently had a heart attack or stroke will also be advised to take daily low-dose aspirin to help to prevent it from happening again. Low-dose aspirin is available on prescription, or you can buy some brands at pharmacies, without a prescription.
However, do not take regular low-dose aspirin without discussing the pros and cons of doing so with your doctor. At higher doses, aspirin is used to relieve pain and inflammation caused by rheumatic and muscular pain. There is more information about this use of aspirin in other leaflets. What is aspirin? Aspirin is a salicylate (sa-LIS-il-ate). It works by reducing substances in the body that cause pain, fever, and inflammation. Aspirin is used to treat pain, and reduce fever or inflammation. It is sometimes used to treat or prevent heart attacks, strokes, and chest pain (angina).
Aspirin should be used for cardiovascular conditions only under the supervision of a doctor. Aspirin may also be used for purposes not listed in this medication guide. Before taking this medicine Do not give this medication to a child or teenager with a fever, flu symptoms, or chicken pox. Aspirin can cause Reye’s syndrome, a serious and sometimes fatal condition in children. How should I take aspirin? Use aspirin exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.
Take with food if aspirin upsets your stomach. Do not crush, chew, break, or open an enteric-coated or delayed-release pill. Swallow it whole. The chewable tablet form must be chewed before swallowing. If you use the orally disintegrating tablet or the dispersible tablet, follow all dosing instructions provided with your medicine. If you need surgery, tell the surgeon ahead of time that you are using aspirin. You may need to stop using the medicine for a short time. Do not take this medication if you smell a strong vinegar odor in the aspirin bottle.
The medicine may no longer be effective. Store at room temperature away from moisture and heat. Usual Adult Dose for Ankylosing Spondylitis For treatment of inflammatory diseases such as ankylosing spondylitis, osteoarthritis, rheumatoid arthritis, and SLE-associated arthritis and pleurisy: 3 grams per day in divided doses (spondyloarthropathies may require up to 4 grams per day in divided doses). Serum salicylate levels may be useful in guiding therapeutic decisions regarding dosage titration. Serum salicylate levels of 150 to 300 mcg/mL are associated with anti-inflammatory response.
However, the incidence of toxicity increases with salicylate levels greater than 200 mcg/mL. Usual Adult Dose for Osteoarthritis For treatment of inflammatory diseases such as ankylosing spondylitis, osteoarthritis, rheumatoid arthritis, and SLE-associated arthritis and pleurisy: 3 grams per day in divided doses (spondyloarthropathies may require up to 4 grams per day in divided doses). Serum salicylate levels may be useful in guiding therapeutic decisions regarding dosage titration. Serum salicylate levels of 150 to 300 mcg/mL are associated with anti-inflammatory response.
However, the incidence of toxicity increases with salicylate levels greater than 200 mcg/mL Usual Adult Dose for Fever 325 to 650 mg orally or rectally every 4 hours as needed, not to exceed 4 g/day.

Other Comments Use of a buffered or enteric-coated aspirin formulation may lessen the risk of gastrointestinal intolerance and toxicity. Aspirin should be administered with food or after meals. The absorption of aspirin following rectal administration is slow and erratic. Oral administration is generally preferred. Because of the risk of mucosal damage, oral formulations of aspirin should never be administered by the rectal route. Keep them in a box or cupboard with a lock -or store them well out of the reach of children. Soluble Aspirin Tablets:

Generic Name: aspirin (oral) (AS pir in) Aspirin, or acetylsalicylic acid (ASA) is a salicylate drug, and is generally used as an analgesic (something that relieves pain without producing anesthesia or loss of consciousness) for minor aches and pains, to reduce fever (an antipyretic), and also as an anti-inflammatory drug. Important information about all medicines Never take more than the prescribed dose.
If you suspect that someone has taken an overdose of this medicine, go to the accident and emergency department of your local hospital at once. Take the container with you, even if it is empty. This medicine is for you. Never give it to other people even if their condition appears to be the same as yours. Never keep out-of-date or unwanted medicines. Take them to your local pharmacy which will dispose of them for you. If you have any questions about this medicine ask your pharmacist. Aspirin is used to relieve pain such as headache, toothache and period pain.
It is also used to treat cold and ‘flu-like’ symptoms and reduce fever in adults (over 16 years of age). Aspirin may also be used to reduce inflammation in muscular aches and pains, but other anti-inflammatory medicines are often preferred. Aspirin works by reducing the production of chemicals called prostaglandins which cause pain. Aspirin is also used in lower doses to reduce the stickiness of platelets in the blood, which helps to prevent unwanted blood clots from forming within the body. There is more information about this in a separate leaflet called ‘Aspirin anti-platelet’.
Before taking aspirin Before taking aspirin make sure your doctor, dentist or pharmacist knows: If you are pregnant, trying for a baby or breast-feeding. If you are under 16 years of age or over 65 years of age. If you have asthma or any other allergic disorder. If you have ever had a stomach ulcer. If you have liver or kidney problems. If you have gout. If you have a blood disorder such as haemophilia or G6PD deficiency. If you have ever had an allergic or unusual reaction to any non-steroidal anti-inflammatory drug (NSAID) such as naproxen, diclofenac and ibuprofen.
If you have ever had an allergic reaction to any other medicine. If you are taking other medicines, including those available to buy without a prescription, herbal and complementary medicines. How to take aspirin Before starting this treatment, read the manufacturer’s printed information leaflet from the pack. Take aspirin exactly as you have been directed by your doctor, dentist or pharmacist, or as directed on the label of the container. Dosage instructions may vary depending on the type of aspirin you are taking and the condition you are being treated for.
The recommended dose ranges from one to three (300mg) tablets every 4-6 hours when needed, but you should not take more than 4g (13 tablets) in a 24-hour period. If you have been supplied aspirin tablets or dispersible tablets, you should take these with a meal, or after a snack. This will help prevent indigestion as a result of irritation to your stomach. Dispersible (or soluble) tablets, should be taken dissolved into a small glass of water before swallowing. If you have been supplied aspirin enteric-coated tablets you should swallow them whole with a drink of water.
Do not chew or crush these tablets as this will damage the special coating. Also, if you take indigestion remedies, do not take them two hours before or after you take enteric-coated aspirin tablets. You should drink plenty of water while you are taking aspirin. This is because aspirin may cause problems if you take it when you are dehydrated. If you have been supplied aspirin suppositories, follow the instructions below for use: If the suppository is too soft, it may be chilled in the refrigerator or under cold running water before unwrapping.
Remove the wrapping and moisten the suppository with water. Lie on your side and draw your knees up towards your chest. Using your finger, gently push the suppository into your back passage as far as possible, pointed end first. Lower your legs to a comfortable position to help you to hold the suppository in place. Wash you hands afterwards. Getting the most from your treatment Aspirin must not be given to children under the age of 16 to treat minor illnesses. This is because there is a possible association between aspirin and a condition known as Reye’s syndrome when it is given to children.
Reye’s syndrome is a very rare condition, but it can be fatal. Do not take any other medicines containing aspirin at the same time as this medicine. Remember many common ‘over-the-counter’ preparations also contain aspirin. Always read the label to check, or ask your pharmacist for advice. Taking too much aspirin can cause serious problems. If you suspect that you have taken more than the prescribed dose, or if a child has accidentally taken aspirin, contact your local accident and emergency department for advice straight away.
