Indications & Clinical Uses

Nevirapine is an antiretroviral medication that targets the HIV‑1 reverse transcriptase enzyme, forming part of combination therapy for viral suppression.

  • HIV‑1 infection: reduces viral load and helps restore immune function when used with other antiretrovirals.

How It Works

  • Nevirapine binds to a hydrophobic pocket of the HIV‑1 reverse transcriptase enzyme, inducing a conformational change that blocks the enzyme’s activity. This inhibition prevents the transcription of viral RNA into DNA, thereby halting replication of the virus within infected cells.

Side Effects

Nevirapine may cause a range of adverse reactions, from mild to severe. Monitoring and prompt reporting of symptoms are essential.

Common Side Effects

  • Rash: mild to moderate skin eruptions.
  • Nausea: occasional upset stomach.
  • Fatigue: feeling unusually tired.
  • Headache: mild to moderate intensity.
  • Diarrhoea: loose stools.
  • Abdominal pain: discomfort in the stomach area.

Serious or Rare Side Effects

  • Stevens‑Johnson syndrome: severe skin reaction requiring immediate medical attention.
  • Hepatic failure: signs of liver dysfunction such as jaundice.
  • Severe hypersensitivity: swelling, fever, or breathing difficulty.
  • Hepatotoxicity: elevated liver enzymes indicating injury.
  • Neutropenia: reduced white blood cell count increasing infection risk.
  • Life‑threatening rash: extensive skin involvement.

Precautions & Warnings

Nevirapine requires careful monitoring due to its potential for liver and skin toxicity.

  • Liver monitoring: perform baseline and periodic liver function tests.
  • Rash assessment: examine any skin changes promptly.
  • Avoid potent CYP3A4 inducers: drugs like rifampicin may lower nevirapine levels.
  • Caution in hepatitis B/C: patients with pre‑existing liver disease need close observation.
  • Pregnancy considerations: weigh maternal benefits against potential fetal risks.
  • Store below 25°C: keep in the original packaging, protect from moisture and direct sunlight.

Avoid Interactions

Nevirapine interacts with several medicines that can alter its effectiveness or increase toxicity.

Major Interactions (Avoid)

  • Rifampicin: reduces nevirapine plasma concentrations.
  • St. John’s wort: strong CYP3A4 inducer that lowers drug levels.
  • Carbamazepine: may decrease nevirapine exposure.

Moderate Interactions (Monitor Closely)

  • Efavirenz: combined NNRTIs can increase risk of liver toxicity.
  • Protease inhibitors (e.g., ritonavir): may raise nevirapine concentrations, requiring dose adjustment.

Frequently Asked Questions

Nevirapine Milpharm is an antiretroviral medication indicated for the treatment of HIV‑1 infection. It is used as part of combination therapy to lower viral load, improve immune function, and reduce the risk of disease progression in adults and adolescents living with HIV.

Nevirapine belongs to the non‑nucleoside reverse transcriptase inhibitor class. It binds to a specific hydrophobic pocket on the HIV‑1 reverse transcriptase enzyme, causing a conformational change that blocks the enzyme’s activity. This prevents the conversion of viral RNA into DNA, halting viral replication.

The exact dosing regimen for Nevirapine is determined by the prescribing clinician based on the patient’s clinical status, weight, and co‑medications. Standard practice involves an initial lead‑in dose followed by a maintenance dose, but the prescriber sets the final schedule.

Nevirapine’s pregnancy category is listed as unknown, and safety data are limited. Use during pregnancy or lactation should be considered only when the potential benefit to the mother outweighs possible risks to the fetus or infant, and it should be prescribed under specialist supervision.

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.

Nevirapine is an NNRTI, similar to efavirenz and delavirdine, but differs in its metabolic profile and side‑effect spectrum. Compared with protease inhibitors, NNRTIs generally have fewer drug‑food interactions but may carry a higher risk of skin rash and hepatic toxicity, requiring individualized selection.

Nevirapine Milpharm tablets should be stored at temperatures below 25 °C, in the original container, protected from moisture and direct sunlight. Keep the product out of reach of children and avoid exposing it to excessive heat or humidity.

Nevirapine is taken orally, usually with food or a light snack to reduce gastrointestinal discomfort. The tablets are swallowed whole with water and should be taken exactly as prescribed, without crushing or splitting unless instructed by a healthcare professional.

The most critical adverse events include severe skin reactions such as Stevens‑Johnson syndrome, life‑threatening hepatic failure, and hypersensitivity reactions that may involve fever, rash, and organ involvement. Prompt medical evaluation is essential if any of these symptoms appear.

Nevirapine is contraindicated in individuals with a known hypersensitivity to the drug or any NNRTI, patients with severe pre‑existing liver disease, and those who have previously experienced severe rash or hepatic reactions to nevirapine. Caution is also advised for patients with active hepatitis B or C.
