Paracetamol/Ibuprofen Haleon (Ibuprofen, Paracetamol)

Paracetamol/Ibuprofen Haleon combines two analgesic pathways to manage mild‑to‑moderate pain and fever.

• Headache: provides rapid relief of tension‑type and migraine‑associated pain.
• Dental pain: reduces postoperative discomfort after dental procedures.
• Musculoskeletal pain: alleviates aches from strains, sprains and low‑back pain.
• Fever: lowers elevated body temperature in febrile adults and children.
• Menstrual discomfort: eases cramps and associated low‑grade pain.

• Ibuprofen inhibits cyclo‑oxygenase (COX‑1 and COX‑2) enzymes, decreasing prostaglandin synthesis that mediates inflammation, pain and fever. Paracetamol acts centrally by inhibiting a variant of the COX enzyme and modulating serotonergic pathways, which reduces pain perception and resets the hypothalamic temperature set‑point. The combined effect provides additive analgesic and antipyretic activity without significantly increasing gastrointestinal risk when used at recommended doses.

Paracetamol/Ibuprofen Haleon may cause a range of adverse reactions, most of which are dose‑dependent and reversible.

Common Side Effects

• Gastrointestinal discomfort: mild nausea, dyspepsia or abdominal pain.
• Headache: transient worsening of headache in some users.
• Dizziness: occasional light‑headedness or vertigo.
• Skin redness: mild rash or flushing.
• Elevated liver enzymes: mild, transient increase in hepatic markers.

Serious or Rare Side Effects

• Gastrointestinal bleeding: ulceration or hemorrhage, especially with prolonged use.
• Renal impairment: reduced kidney function or acute kidney injury.
• Severe skin reactions: Stevens‑Johnson syndrome or toxic epidermal necrolysis.
• Anaphylaxis: rare systemic allergic response requiring immediate medical attention.
• Hepatotoxicity: significant liver injury, particularly with overdose or pre‑existing liver disease.

When using Paracetamol/Ibuprofen Haleon, consider the following safety measures:

• Assess renal function: avoid use in patients with severe chronic kidney disease.
• Monitor liver health: caution in individuals with hepatic impairment or chronic alcohol use.
• Avoid concurrent NSAIDs: do not combine with other ibuprofen‑type products to reduce gastrointestinal risk.
• Limit duration: use the lowest effective dose for the shortest possible time.
• Pregnancy and lactation: consult a healthcare professional before use in pregnant or breastfeeding women.
• Store below 25°C: keep in the original packaging, protect from moisture and direct sunlight.

Paracetamol/Ibuprofen Haleon can interact with several medication classes, requiring attention to dosing and monitoring.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): increased risk of bleeding.
• High‑dose aspirin or other NSAIDs: heightened gastrointestinal toxicity.
• Lithium: ibuprofen may raise serum lithium levels, risking toxicity.

Moderate Interactions (Monitor Closely)

• ACE inhibitors or ARBs: potential reduction in renal function.
• Diuretics: may enhance renal effects of ibuprofen.
• Methotrexate: ibuprofen can reduce clearance, increasing toxicity risk.
• Selective serotonin reuptake inhibitors (SSRIs): combined use may raise bleeding risk.
