Paracodin (Dihydrocodeine Tartrate)

Paracodin (dihydrocodeine) acts on the central nervous system to provide relief in several pain‑related and cough‑related conditions.

• Moderate acute pain: helps relieve pain where non‑opioid analgesics are insufficient.
• Chronic non‑cancer pain: used as part of a stepped‑care approach for ongoing pain management.
• Cough suppression: reduces the urge to cough in cases of irritating or persistent cough.
• Post‑operative pain: provides short‑term relief after surgical procedures.
• Dental pain: alleviates pain associated with dental extractions or procedures.

• Dihydrocodeine tartrate is a semi‑synthetic opioid that binds to µ‑opioid receptors in the central nervous system. Activation of these receptors reduces neuronal excitability, decreasing the perception of pain and suppressing the cough reflex by acting on the medullary cough centre.

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

Common Side Effects

• Drowsiness: feeling unusually sleepy or fatigued.
• Nausea: mild to moderate upset stomach.
• Constipation: reduced bowel movements or hard stools.
• Dizziness: light‑headed sensation, especially when standing quickly.
• Dry mouth: reduced salivation leading to a parched feeling.
• Itching: mild skin irritation or pruritus.

Serious or Rare Side Effects

• Respiratory depression: slowed or shallow breathing that may be life‑threatening.
• Severe allergic reaction: rash, swelling, or difficulty breathing.
• Dependence or addiction: potential for misuse with prolonged use.
• Low blood pressure: sudden drop causing faintness.
• Seizures: rare occurrence of convulsive episodes.
• Liver dysfunction: abnormal liver enzymes or jaundice.

Paracodin should be used only under medical supervision, with attention to patient history and potential risks.

• Assess respiratory function: ensure adequate breathing before initiating therapy.
• Review liver and kidney status: adjust use if organ impairment is present.
• Avoid concurrent CNS depressants: limit use with alcohol, benzodiazepines, or other opioids.
• Monitor for signs of dependence: watch for cravings or withdrawal symptoms.
• Educate on constipation management: advise increased fluid and fiber intake.
• Store at ambient temperature: keep in the original container, protect from moisture and direct sunlight.

Paracodin can interact with several drug classes, altering its efficacy or safety profile.

Major Interactions (Avoid)

• Other opioids: combined use can increase risk of respiratory depression.
• Benzodiazepines: may potentiate central nervous system depression.
• MAO inhibitors: can cause severe hypotension or serotonin syndrome.

Moderate Interactions (Monitor Closely)

• Antihistamines: may enhance drowsiness.
• Antidepressants (SSRIs/SNRIs): potential for increased serotonin levels.
• CYP3A4 inhibitors (e.g., erythromycin): may raise dihydrocodeine plasma concentrations.
