Neofen Plus (Ibuprofen)

Ibuprofen is a topical NSAID that acts locally on inflamed musculoskeletal tissues.

• Minor musculoskeletal pain: reduces pain and tenderness in muscles, tendons and ligaments.
• Sprains and strains: alleviates discomfort and swelling associated with soft‑tissue injuries.
• Osteoarthritis of the knee: provides localized relief of joint pain and stiffness.
• Backache: eases localized low‑back discomfort caused by muscle strain.

• Ibuprofen reversibly inhibits cyclooxygenase‑1 (COX‑1) and cyclooxygenase‑2 (COX‑2) enzymes in peripheral tissues, decreasing the synthesis of prostaglandins that mediate inflammation, pain and fever. When applied topically, the drug penetrates the skin to act directly at the site of inflammation, providing localized therapeutic effects with minimal systemic exposure.

Topical ibuprofen may cause skin‑related reactions and, rarely, systemic adverse events.

Common Side Effects

• Skin irritation: mild redness or discomfort at the application site.
• Burning sensation: transient warmth or tingling after application.
• Itching: localized pruritus.
• Dryness: mild flaking of the skin.
• Rash: non‑allergic erythematous eruption.

Serious or Rare Side Effects

• Allergic dermatitis: severe swelling, blistering or hives.
• Stevens‑Johnson syndrome: rare but life‑threatening skin reaction.
• Systemic NSAID toxicity: gastrointestinal ulceration or bleeding if absorbed in large amounts.
• Renal impairment: reduced kidney function in susceptible individuals.
• Hepatotoxicity: abnormal liver enzymes with extensive use.

When using topical ibuprofen, consider the following safety measures.

• Assess skin integrity: avoid application on damaged or infected skin.
• Limit area: do not cover large body surfaces or use excessive amounts.
• Duration of use: restrict treatment to the recommended period, typically not exceeding 7‑10 days without medical advice.
• Concomitant NSAIDs: avoid simultaneous oral NSAID therapy to reduce systemic risk.
• Underlying conditions: use caution in patients with asthma, cardiovascular disease or renal impairment.
• Store at room temperature: keep in the original packaging, protect from moisture and direct heat.

Topical ibuprofen can interact with systemic medications; awareness of these interactions helps minimize risk.

Major Interactions (Avoid)

• Oral NSAIDs: increased risk of systemic adverse effects such as gastrointestinal bleeding.
• Anticoagulants (e.g., warfarin): heightened bleeding tendency.
• Lithium: potential increase in lithium serum levels.

Moderate Interactions (Monitor Closely)

• ACE inhibitors or ARBs: possible reduction in renal function when combined.
• Diuretics: may enhance renal adverse effects.
• Corticosteroids: additive risk of skin thinning and ulceration.
• Methotrexate: potential for increased toxicity.
