Kidofen Duo (Ibuprofen, Paracetamol)

Kidofen Duo, a combination NSAID/analgesic, is indicated for conditions where pain or fever are present.

• Pain relief: alleviates mild to moderate pain such as headache, toothache or postoperative discomfort.
• Fever reduction: lowers elevated body temperature in febrile states.
• Headache: provides rapid relief of tension‑type or mild migraine pain.
• Musculoskeletal pain: eases discomfort associated with strains, sprains or arthritis.

• Ibuprofen inhibits cyclo‑oxygenase (COX‑1 and COX‑2) enzymes, decreasing prostaglandin synthesis and thereby reducing inflammation, pain and fever. Paracetamol acts centrally by inhibiting COX activity in the brain and modulating serotonergic pathways, producing analgesic and antipyretic effects without significant peripheral anti‑inflammatory activity. The synergy allows lower individual doses, potentially minimizing dose‑related adverse events while maintaining efficacy.

Kidofen Duo may cause a range of adverse reactions, varying from mild to serious.

Common Side Effects

• Gastrointestinal discomfort: nausea, dyspepsia, or mild abdominal pain that usually resolves without treatment.
• Headache: transient headache may occur, often mild and self‑limiting.
• Dizziness: occasional light‑headedness or vertigo, typically short‑lasting.
• Skin rash: mild erythematous rash or itching, generally reversible after discontinuation.

Serious or Rare Side Effects

• Gastrointestinal bleeding: ulceration or hemorrhage that can present as black stools or vomiting blood.
• Severe allergic reaction: anaphylaxis, facial swelling, hives, or bronchospasm requiring immediate medical attention.
• Hepatotoxicity: elevated liver enzymes or clinically significant liver injury, especially with overdose or chronic use.
• Renal impairment: acute kidney injury, particularly in patients with dehydration or pre‑existing renal disease.

When using Kidofen Duo, several precautions should be observed to ensure safe administration.

• Assess renal function: evaluate kidney status before use, especially in patients with chronic renal disease.
• Avoid in known hypersensitivity: do not use if the patient has allergy to ibuprofen, paracetamol or any excipients.
• Limit concurrent alcohol intake: alcohol may increase risk of liver injury and gastrointestinal irritation.
• Monitor liver enzymes: prolonged high‑dose therapy may affect hepatic function, requiring periodic testing.
• Store at room temperature: keep in the original packaging, protect from moisture and direct sunlight.

Kidofen Duo can interact with other medicines; awareness of major and moderate interactions helps prevent adverse outcomes.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): increased risk of bleeding.
• Other NSAIDs or COX‑2 inhibitors: additive gastrointestinal toxicity.
• High‑dose corticosteroids: heightened ulcer risk.
• Methotrexate: reduced clearance leading to toxicity.

Moderate Interactions (Monitor Closely)

• Diuretics: may reduce renal perfusion, increasing risk of kidney injury.
• ACE inhibitors or ARBs: possible decline in renal function when combined.
• Lithium: increased serum lithium levels, risk of toxicity.
• Alcohol: enhanced hepatotoxic potential.
