Nealgin (Paracetamol, Propyphenazone, Caffeine)

Nealgin combines analgesic and antipyretic actions to manage common pain‑related conditions.

• Mild to moderate pain: provides rapid relief of muscle, dental or postoperative discomfort.
• Fever: lowers elevated body temperature associated with infections or inflammatory states.
• Headache: alleviates tension‑type and mild migraine episodes.

• Paracetamol acts centrally to inhibit cyclo‑oxygenase enzymes and lower prostaglandin synthesis, producing analgesic and antipyretic effects. Propyphenazone, a non‑steroidal anti‑inflammatory drug, blocks peripheral prostaglandin formation, reducing inflammation and pain. Caffeine antagonises adenosine receptors, enhancing central analgesia and counteracting drowsiness, thereby potentiating the overall therapeutic response.

Nealgin may cause a range of adverse reactions, most of which are mild and reversible.

Common Side Effects

• Nausea or upset stomach.
• Dizziness or light‑headedness.
• Insomnia or restlessness.
• Mild headache.
• Skin rash or itching.
• Increased heart rate.

Serious or Rare Side Effects

• Severe allergic reactions (anaphylaxis, angioedema).
• Hepatotoxicity, especially with excessive paracetamol intake.
• Blood dyscrasias such as agranulocytosis.
• Gastrointestinal bleeding or ulceration.
• Stevens‑Johnson syndrome or toxic epidermal necrolysis.
• Cardiovascular events linked to caffeine excess.

Before using Nealgin, consider the following safety measures.

• Liver function assessment: avoid in patients with severe hepatic impairment.
• Hypersensitivity check: discontinue if allergic reactions occur.
• Hypertension monitoring: caffeine may raise blood pressure.
• Pregnancy and lactation: use only if benefits outweigh potential risks.
• Alcohol avoidance: concurrent alcohol increases liver toxicity risk.
• Store at room temperature: keep in the original pack, protect from moisture.

Nealgin can interact with several medicines; awareness helps prevent complications.

Major Interactions (Avoid)

• Other NSAIDs (e.g., ibuprofen): heightened risk of gastrointestinal bleeding.
• Anticoagulants (e.g., warfarin): increased bleeding tendency.
• Alcohol with paracetamol: potential for severe liver injury.

Moderate Interactions (Monitor Closely)

• CYP1A2 inhibitors (e.g., fluvoxamine): may raise caffeine plasma levels.
• Diuretics: can amplify propyphenazone‑related toxicity.
• Central depressants (e.g., opioids, benzodiazepines): additive sedation or respiratory depression.
