Mexaratio (Paracetamol)

Paracetamol acts centrally to relieve pain and lower fever.

• Pain: provides relief from mild to moderate pain such as headache, toothache, or musculoskeletal discomfort.
• Fever: reduces elevated body temperature associated with infections or inflammatory conditions.
• Post‑operative discomfort: helps manage pain after minor surgical procedures when oral intake is limited.
• Cold‑flu symptoms: alleviates fever and body aches commonly experienced during viral upper respiratory infections.

• Paracetamol exerts its effect primarily by inhibiting the cyclooxygenase (COX) enzymes in the central nervous system, particularly COX‑2, which leads to decreased synthesis of prostaglandins involved in pain signaling and thermoregulation. The peripheral inhibition is minimal, allowing antipyretic and analgesic actions without significant anti‑inflammatory activity. It also modulates serotonergic pathways that contribute to its analgesic profile, and its metabolites are rapidly conjugated in the liver, facilitating elimination.

Paracetamol suppositories are generally well tolerated, but adverse reactions can occur.

Common Side Effects

• Nausea: mild stomach upset may be reported.
• Local irritation: discomfort or mild erythema at the rectal site.
• Rash: occasional skin redness or itching.
• Dizziness: transient light‑headedness in some users.

Serious or Rare Side Effects

• Anaphylaxis: severe allergic reaction requiring immediate medical attention.
• Stevens‑Johnson syndrome: rare skin disorder with blistering.
• Hepatotoxicity: rare liver injury, especially with overdose.
• Blood disorders: uncommon cases of agranulocytosis or thrombocytopenia.

When using Mexaratio, consider the following precautions to ensure safe administration.

• Use in children under 2 years: consult a healthcare professional before administration.
• Avoid in known hypersensitivity to paracetamol or any excipients.
• Do not exceed the recommended total daily dose across all paracetamol‑containing products.
• Caution in patients with liver disease: monitor hepatic function regularly.
• Concurrent use with other hepatotoxic drugs: assess risk and consider dose adjustment.
• Store at room temperature: keep in the original pack, protect from moisture and heat.

Paracetamol may interact with other medicines; review the following interactions.

Major Interactions (Avoid)

• Co‑administration with other paracetamol‑containing products: risk of overdose and liver toxicity.
• Use with warfarin: may potentiate anticoagulant effect and increase bleeding risk.
• Combination with hepatotoxic agents (e.g., isoniazid, methotrexate): heightened potential for liver injury.

Moderate Interactions (Monitor Closely)

• Alcohol consumption: can amplify hepatic stress, especially with regular use.
• Carbamazepine or phenobarbital: may increase paracetamol metabolism, reducing efficacy.
• Certain anticonvulsants (e.g., phenytoin): may alter plasma levels, requiring observation.
