Nurofen is a well-established, over-the-counter (OTC) analgesic and anti-inflammatory medication, with its active ingredient ibuprofen belonging to the class of nonsteroidal anti-inflammatory drugs (NSAIDs). It is a first-line therapeutic option for the management of mild to moderate pain, inflammation, and fever. Its mechanism of action, through the inhibition of cyclooxygenase (COX) enzymes, provides a dual therapeutic effect, making it a versatile choice for a range of common conditions. This product card provides a comprehensive, expert-level overview of its appropriate use, pharmacological profile, and essential safety information.
Features
- Active Ingredient: Ibuprofen (typically 200mg per tablet/caplet in standard OTC formulations).
- Drug Class: Nonsteroidal Anti-Inflammatory Drug (NSAID).
- Formulations: Available as film-coated tablets, caplets, liquid capsules for faster absorption, and a suspension for pediatric use.
- Mechanism of Action: Potent inhibitor of cyclooxygenase-1 and cyclooxygenase-2 (COX-1 and COX-2) enzymes, reducing the synthesis of prostaglandins, which are mediators of pain, inflammation, and fever.
- Onset of Action: Typically begins to relieve pain within 30 minutes.
- Duration of Action: Provides relief for approximately 4 to 6 hours per dose.
Benefits
- Provides effective and targeted relief from a broad spectrum of pain types, including headache, dental pain, backache, and muscular aches.
- Reduces inflammation at the source of pain, such as in sprains, strains, and arthritis, addressing the cause rather than just masking the sensation.
- Effectively reduces fever (antipyretic effect) by acting on the hypothalamus, the body’s temperature regulator.
- Offers a predictable pharmacokinetic profile with a well-understood safety margin when used as directed for short-term relief.
- Available in multiple formats to suit patient preference and specific needs, including options designed for faster absorption.
Common use
Nurofen is indicated for the short-term symptomatic relief of:
- Headaches, including tension-type headaches and migraines.
- Dental pain (e.g., following extraction or toothache).
- Musculoskeletal pain, such as backache, rheumatic pain, and muscular strains.
- Period pain (primary dysmenorrhea).
- The symptoms of colds and influenza, including sore throat and fever.
- Minor arthritic pain.
It is crucial to use the lowest effective dose for the shortest duration necessary to control symptoms.
Dosage and direction
For Adults and Children over 12 years:
- The usual dose is 200mg to 400mg (1 to 2 tablets) up to three times a day as required.
- Doses should be taken with a minimum interval of 4 to 6 hours.
- Do not exceed 1200mg (6 tablets) in any 24-hour period.
- Take with food or a glass of milk to minimize the potential for gastric upset.
- Swallow the tablet whole with water; do not crush, chew, or break.
For Children:
- Always use the specific pediatric suspension formulation and follow the dosage instructions on the package based on the child’s weight and age. Consult a physician or pharmacist for children under 6 months of age.
Precautions
- Gastrointestinal Risk: NSAIDs, including ibuprofen, are associated with an increased risk of serious gastrointestinal (GI) adverse events including bleeding, ulceration, and perforation, which can be fatal. This risk is higher in the elderly, those with a history of GI events, and with prolonged use.
- Cardiovascular Risk: Long-term use of NSAIDs may increase the risk of serious cardiovascular thrombotic events, such as myocardial infarction or stroke. This risk may increase with duration of use and in patients with pre-existing cardiovascular disease.
- Renal Function: Ibuprofen can cause renal toxicity. Use with caution in patients with impaired renal function, heart failure, volume depletion, or in those taking diuretics or ACE inhibitors.
- Asthma: Use with caution in patients with asthma, as exacerbation of the condition can occur.
- Third Trimester of Pregnancy: Do not use during the third trimester of pregnancy as it may cause premature closure of the fetal ductus arteriosus and delay labor and birth.
- Dehydration: Avoid use in dehydrated patients, as this increases the risk of renal complications.
Contraindications
Nurofen is contraindicated in patients with:
- Known hypersensitivity (allergy) to ibuprofen, other NSAIDs, or any of the product’s excipients.
- A history of asthma, urticaria, or other allergic-type reactions after taking aspirin or other NSAIDs.
- Active peptic ulceration or a history of recurrent ulceration/bleeding.
- Severe hepatic impairment or active liver disease.
- Severe heart failure.
- Third trimester of pregnancy.
- In the setting of coronary artery bypass graft (CABG) surgery.
Possible side effect
Like all medicines, Nurofen can cause side effects, although not everybody gets them. Common (may affect up to 1 in 10 people):
- Gastrointestinal: Dyspepsia, nausea, vomiting, abdominal pain, diarrhea, flatulence.
- Neurological: Headache, dizziness. Uncommon (may affect up to 1 in 100 people):
- Gastrointestinal: Gastric or duodenal ulceration, GI hemorrhage.
- Dermatological: Various rashes.
- Renal: Impaired renal function. Rare/Very Rare:
- Severe hypersensitivity reactions (e.g., anaphylaxis, bronchospasm).
- Severe skin reactions (e.g., Stevens-Johnson syndrome, toxic epidermal necrolysis).
- Hepatitis, jaundice.
- Heart failure, hypertension, edema.
- Aseptic meningitis (particularly in patients with autoimmune disorders).
- Hematological effects (e.g., leukopenia, thrombocytopenia).
Patients should stop taking the medication and seek immediate medical attention if signs of allergy (swelling of the face, difficulty breathing) or severe skin reactions appear.
Drug interaction
Ibuprofen can interact with many other medicines. Inform your doctor or pharmacist if you are taking:
- Other NSAIDs (including aspirin and COX-2 inhibitors): Increased risk of GI side effects.
- Anticoagulants (e.g., warfarin): Increased risk of bleeding.
- Antihypertensives (e.g., ACE inhibitors, angiotensin-II receptor antagonists, beta-blockers, diuretics): Ibuprofen may reduce their effectiveness and increase the risk of renal impairment.
- Corticosteroids (e.g., prednisolone): Increased risk of GI ulceration.
- Selective Serotonin Reuptake Inhibitors (SSRIs): Increased risk of GI bleeding.
- Methotrexate: Ibuprofen may increase plasma levels of methotrexate, increasing its toxicity.
- Lithium: Ibuprofen may decrease the elimination of lithium, increasing the risk of lithium toxicity.
Missed dose
Nurofen is taken on an “as-needed” basis for pain relief. It is not a scheduled medication. Therefore, if a dose is missed, take it as soon as you remember if you are still in pain. If it is almost time for your next potential dose, skip the missed dose. Do not take a double dose to make up for a missed one.
Overdose
Symptoms: Overdose symptoms are typically extensions of the drug’s pharmacological effects. These can include nausea, vomiting, epigastric pain, headache, drowsiness, dizziness, tinnitus, and nystagmus. In severe cases, more serious effects may occur, including metabolic acidosis, GI bleeding, hypotension, acute renal failure, respiratory depression, coma, and convulsions. Management: Seek immediate medical attention. Management is supportive and includes gastric lavage or activated charcoal (if ingestion was recent), monitoring of vital signs, and correction of electrolyte imbalances. Hemodialysis is not effective due to high protein binding.
Storage
- Store in the original package below 25°C (77°F).
- Keep out of sight and reach of children.
- Do not use after the expiration date printed on the pack.
