Nefopam Hydrochloride Dawa (Nefopam Hydrochloride)

Nefopam Hydrochloride is a centrally acting analgesic used for pain conditions where non‑opioid therapy is indicated.

• Moderate to severe acute pain: provides effective relief without opioid‑related side effects.
• Post‑operative pain: helps control pain after surgical procedures, facilitating recovery.

• Nefopam Hydrochloride inhibits the reuptake of norepinephrine, serotonin and dopamine in the central nervous system, increasing the synaptic concentrations of these neurotransmitters. This multimodal action produces analgesia by modulating pain pathways without engaging opioid receptors, resulting in central analgesic effects.

Nefopam Hydrochloride may cause a range of adverse reactions, most of which are dose‑related and reversible.

Common Side Effects

• Nausea: mild to moderate stomach upset.
• Dizziness: transient light‑headedness.
• Dry mouth: reduced salivation.
• Sweating: increased perspiration.
• Constipation: reduced bowel movements.
• Blurred vision: temporary visual disturbance.

Serious or Rare Side Effects

• Tachycardia: rapid heart rate requiring monitoring.
• Seizures: rare convulsive episodes, especially in predisposed individuals.
• Severe hypotension: marked drop in blood pressure.
• Allergic reactions: rash, itching, or anaphylaxis.
• Hepatic dysfunction: abnormal liver enzymes or jaundice.

Before prescribing Nefopam Hydrochloride, clinicians should consider several safety aspects.

• Renal function assessment: adjust use in patients with impaired kidney function.
• Cardiovascular monitoring: observe for tachycardia or hypertension.
• Seizure history: avoid in patients with uncontrolled epilepsy.
• Concomitant serotonergic drugs: evaluate risk of serotonin syndrome.
• Discontinuation: taper gradually to prevent withdrawal symptoms.
• Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Nefopam Hydrochloride can interact with several medication classes, influencing efficacy or safety.

Major Interactions (Avoid)

• Monoamine oxidase inhibitors (MAOIs): risk of severe serotonin syndrome.
• Selective serotonin reuptake inhibitors (SSRIs): increased serotonergic activity.
• Tricyclic antidepressants (TCAs): heightened risk of cardiovascular side effects.

Moderate Interactions (Monitor Closely)

• Antihypertensive agents: possible additive blood pressure reduction.
• Anticholinergic drugs: may exacerbate dry mouth and constipation.
• Central nervous system depressants: enhanced sedation or dizziness.
