Panacit (Paracetamol)

Panacit (paracetamol) is used across several common pain‑related pathways and fever mechanisms.

• Headache: provides relief from mild to moderate tension‑type headaches.
• Fever: reduces elevated body temperature in febrile illnesses.
• Musculoskeletal pain: eases discomfort from strains, sprains and minor joint aches.
• Dental pain: alleviates pain associated with toothache or dental procedures.
• Cold‑related discomfort: helps lessen aches and chills that accompany upper‑respiratory infections.

• Paracetamol acts centrally by inhibiting cyclo‑oxygenase enzymes, primarily COX‑2, within the brain and spinal cord, which reduces prostaglandin synthesis linked to pain and temperature regulation. It also modulates serotonergic pathways that contribute to its antipyretic and analgesic effects, without significant peripheral anti‑inflammatory activity.

Paracetamol is generally well tolerated, but adverse reactions can occur.

Common Side Effects

• Nausea: mild stomach upset may be reported.
• Skin rash: occasional mild erythema or itching.
• Elevated liver enzymes: transient increase in laboratory values.

Serious or Rare Side Effects

• Stevens‑Johnson syndrome: severe skin reaction requiring immediate medical attention.
• Hepatotoxicity: risk of liver injury, especially with overdose or chronic high‑dose use.
• Anaphylaxis: rare allergic reaction that can be life‑threatening.
• Blood disorders: uncommon cases of agranulocytosis or thrombocytopenia.

When using Panacit, consider the following safety measures:

• Dose limitation: adhere to maximum daily amount to avoid liver toxicity.
• Alcohol use: limit intake as combined effect increases hepatic risk.
• Pre‑existing liver disease: use only under medical supervision.
• Pregnancy and lactation: consult healthcare professional before use.
• Children: ensure age‑appropriate dosing and formulation.
• Store below 25°C: keep in the original packaging, protect from moisture and direct sunlight.

Paracetamol may interact with several medicines; monitoring is advised.

Major Interactions (Avoid)

• Warfarin: increased anticoagulant effect may raise bleeding risk.
• Isoniazid: combined use can enhance risk of liver toxicity.

Moderate Interactions (Monitor Closely)

• Antiepileptics (e.g., carbamazepine, phenytoin): may reduce paracetamol plasma levels.
• Certain HIV protease inhibitors: may alter metabolism and increase toxicity risk.
• Rifampicin: may increase hepatic metabolism, lowering efficacy.
• Oral contraceptives: may slightly increase hepatotoxic potential.
