Indications & Clinical Uses

  • Nefopam Hydrochloride is used to manage pain conditions that respond to central analgesic mechanisms.
  • Acute postoperative pain: provides analgesia to reduce pain after surgical procedures.
  • Musculoskeletal pain: relieves pain associated with strains, sprains and other musculoskeletal injuries.
  • Moderate pain conditions: offers relief for various moderate intensity pain states where opioid therapy is not required.

How It Works

  • Nefopam Hydrochloride inhibits the reuptake of norepinephrine, serotonin and dopamine, increasing their synaptic concentrations, and blocks voltage‑dependent sodium channels in neuronal membranes. These actions reduce central pain transmission and produce analgesic effects without opioid receptor involvement.

Side Effects

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

Common Side Effects

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

Serious or Rare Side Effects

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

Precautions & Warnings

  • Before prescribing Nefopam Hydrochloride, clinicians should consider several safety aspects.
  • Cardiovascular assessment: evaluate heart rate and blood pressure.
  • Seizure risk: monitor patients with a history of epilepsy.
  • Hepatic impairment: use with caution in liver disease.
  • Abrupt discontinuation: avoid sudden stop to prevent withdrawal phenomena.
  • Drug interaction review: check concomitant serotonergic agents.
  • Store at ambient temperature: keep in original packaging, protect from moisture.

Avoid Interactions

Nefopam Hydrochloride can interact with other medicines, influencing safety and efficacy.

Major Interactions (Avoid)

  • MAO inhibitors: risk of severe hypertension.
  • SSRIs: potential serotonin syndrome.
  • Tricyclic antidepressants: increased serotonergic activity.
  • Antihypertensive agents: additive blood pressure lowering.
  • Anticholinergic drugs: heightened anticholinergic side effects.

Moderate Interactions (Monitor Closely)

  • CYP450 inhibitors/inducers: may alter plasma levels.
  • NSAIDs: increased gastrointestinal bleeding risk.
  • Diuretics: possible electrolyte disturbances.
  • Alcohol: enhanced central nervous system depression.
  • Beta‑blockers: monitor for bradycardia.

Frequently Asked Questions

Nefopam Hydrochloride is a non‑opioid centrally acting analgesic indicated for the relief of acute postoperative pain, musculoskeletal pain and other moderate pain conditions where opioid therapy is not required.

The drug blocks the reuptake of norepinephrine, serotonin and dopamine while also inhibiting voltage‑dependent sodium channels. These combined actions reduce central pain transmission, providing analgesia without engaging opioid receptors.

The appropriate dose of Nefopam Hydrochloride is determined by the prescribing clinician based on the patient’s condition, severity of pain, age, renal and hepatic function, and other individual factors.

Safety data for Nefopam Hydrochloride in pregnancy and lactation are limited. It should be used only if the potential benefit justifies the potential risk to the fetus or infant, and the decision should be made by a qualified healthcare professional.

To place an order, submit an enquiry on the product page at gnhindia.com specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any necessary import documentation.

Unlike opioids, Nefopam does not act on opioid receptors, reducing the risk of dependence, respiratory depression and constipation. It provides effective analgesia for moderate pain but may cause different side‑effects such as sweating or tachycardia, and its efficacy for severe pain is generally lower than that of strong opioids.

Nefopam Hydrochloride should be stored at ambient temperature, below 25 °C, in its original packaging, protected from moisture and direct sunlight. Keep the product out of reach of children and avoid exposure to extreme temperatures.

The medication is taken orally, usually in tablet form, with or without food as directed by the prescriber. Patients should swallow the tablet whole with a glass of water and follow the dosing schedule provided by their healthcare professional.

Serious adverse events, although rare, include tachycardia, severe hypotension, seizures, cardiac arrhythmias and allergic reactions such as anaphylaxis. Patients should seek immediate medical attention if they experience any of these symptoms.

Nefopam Hydrochloride is contraindicated in patients with known hypersensitivity to the drug, those taking monoamine oxidase inhibitors, and individuals with uncontrolled hypertension or severe cardiac disease. Caution is also advised for patients with a history of seizures or significant liver impairment.
