Paralgin Forte (Codeine Phosphate Sesquihydrate, Paracetamol)

Paralgin Forte combines a weak opioid with a non‑opioid analgesic, acting on pain pathways to provide relief in several common conditions.

• Mild to moderate acute pain: helps alleviate pain associated with injuries, dental procedures or postoperative recovery.
• Fever: reduces elevated body temperature in febrile illnesses.
• Headache tension-type: eases discomfort from tension‑type headaches.
• Musculoskeletal aches: assists in managing muscle and joint soreness.
• Dysmenorrhea: provides relief from menstrual cramp pain.

• Codeine is metabolised to morphine, which binds to µ‑opioid receptors in the central nervous system, diminishing the perception of pain. Paracetamol acts centrally by inhibiting cyclooxygenase enzymes, lowering prostaglandin synthesis and contributing antipyretic effects. The combined action produces synergistic analgesia and fever reduction.

Paralgin Forte may cause a range of adverse reactions, most of which are dose‑dependent and reversible.

Common Side Effects

• Nausea: mild stomach upset or queasiness.
• Constipation: reduced bowel movements or hard stools.
• Drowsiness: feeling unusually sleepy or fatigued.
• Dizziness: light‑headed sensation, especially when standing quickly.
• Dry mouth: reduced salivation leading to a sticky feeling.
• Sweating: increased perspiration without exertion.

Serious or Rare Side Effects

• Respiratory depression: slowed or shallow breathing, potentially life‑threatening.
• Severe allergic reaction: rash, itching, swelling, or difficulty breathing.
• Hepatotoxicity: liver injury indicated by jaundice or abnormal liver tests.
• Dependence or misuse: signs of tolerance, craving, or withdrawal.
• Low blood pressure: marked drop causing faintness or shock.
• Seizures: uncontrolled convulsions, especially with overdose.

When using Paralgin Forte, consider the following safety measures:

• Assess pain severity: ensure the product is appropriate for mild to moderate pain.
• Review medical history: check for respiratory disorders, liver disease, or opioid sensitivity.
• Avoid alcohol: concurrent use can increase sedation and respiratory risk.
• Monitor for dependence: watch for signs of tolerance, craving, or withdrawal.
• Use in pregnancy only if essential: evaluate risks versus benefits with a healthcare professional.
• Store at below 25°C: keep in the original packaging, protect from moisture and direct sunlight.

Paralgin Forte can interact with several medicines, altering its effectiveness or safety profile.

Major Interactions (Avoid)

• CNS depressants: combined use with alcohol, benzodiazepines or other opioids may cause profound sedation and respiratory depression.
• MAO inhibitors: concurrent use can precipitate severe hypertension or serotonin syndrome.
• CYP2D6 inhibitors: drugs such as fluoxetine may reduce conversion of codeine to morphine, lowering analgesic effect.

Moderate Interactions (Monitor Closely)

• Anticoagulants: paracetamol may enhance warfarin’s anticoagulant effect, requiring INR monitoring.\n- Hepatotoxic drugs: concurrent use with other liver‑affecting agents can increase risk of liver injury.
• Antihistamines: may add to drowsiness or dizziness.
• Diuretics: can exacerbate low blood pressure.
• Anticonvulsants: may alter paracetamol metabolism.
