What ALEVE 24 Hour is used for

ALEVE 24 Hour belongs to a family of medicines called Non-Steroidal Anti-Inflammatory Drugs (NSAIDs). These medicines work by relieving pain and inflammation.

ALEVE 24 Hour relieves persistent pain and reduces inflammation (swelling, redness and soreness) that may occur in the following:

  • body pain
  • back pain
  • neck and shoulder pain
  • muscle pain
  • sprains and strains
  • osteoarthritis
  • arthritic and rheumatic conditions
  • period pain
  • dental pain
  • sinus pain
  • cold and flu

ALEVE 24 Hour can also provide temporary relief of stiffness associated with arthritis.

Aleve 24 Hour should be used if pain is likely to last for longer than 12 hours.

Although ALEVE 24 Hour can relieve the symptoms of pain and inflammation, it will not cure your condition.

Use in children statement:
ALEVE 24 Hour is not recommended for use in children (under the age of 12), as there have been no studies of its effects in children.

ALEVE 24 Hour is not addictive.

It is available from your pharmacist.

When you must not take it

Do not take ALEVE 24 Hour if you have an allergy to:

  • any medicine containing naproxen (the active ingredient in ALEVE 24 Hour), aspirin or any other NSAIDs
  • any of the ingredients listed at the end of this leaflet

Many medicines used to treat headache, period pain and other aches and pains contain aspirin or NSAID medicines. If you are not sure if you are taking any of these medicines, ask your pharmacist.

Some of the symptoms of an allergic reaction may include:

  • asthma, wheezing, difficulty breathing or shortness of breath
  • swelling of the face, lips, tongue or other parts of the body which may cause difficulty in swallowing or breathing
  • hives, itching or rash
  • fainting

If you are allergic to aspirin or NSAID medicines and take ALEVE 24 Hour, these symptoms may be severe.

Do not take ALEVE 24 Hour if at the present time you have an ulcer (gastric or duodenal) or other stomach disorders, or bleeding from the stomach or bowel. If you take it, your stomach problem may become worse.

Do not take ALEVE 24 Hour if you have impaired kidney function or heart failure.

Do not take ALEVE 24 Hour in the last 3 months of pregnancy. It may affect the baby, and also delay labour and birth.

Do not take this medicine after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering. If it has expired or is damaged, return it to your pharmacist for disposal.

Do not take this medicine if you are aged 65 years old or over unless your doctor has told you to. Your doctor might tell you to take other lower-dose naproxen tablets instead of Aleve 24 Hour so that you may use the lowest effective dose.

Do not give this medicine to a child under 12 years of age. ALEVE 24 Hour is not recommended for use in children under 12 years of age, as there is not enough information on its use in children under that age.

If you are not sure whether you should start taking this medicine, talk to your pharmacist or doctor.
