Overview

What is Efavirenz?

Efavirenz (EFV) is a non-nucleoside reverse transcriptase inhibitor (NNRTI) used in combination with other antiretrovirals to treat HIV-1. It is typically taken once daily at bedtime due to neuropsychiatric side effects that diminish during sleep.

Mechanism

How Does It Work?

NNRTI binding

Efavirenz binds directly to HIV reverse transcriptase at a site adjacent to the active site, causing a conformational change.

Enzyme inhibition

The conformational change inhibits RNA-dependent and DNA-dependent DNA polymerase activity, blocking viral DNA synthesis.

Viral suppression

Without reverse transcriptase, HIV cannot convert its RNA genome to DNA, halting replication inside CD4+ T cells.

Dosage

How to Use

Timing

Once daily, preferably at bedtime

How to Take

Swallow capsule or tablet whole. Take on an empty stomach — a high-fat meal increases exposure and side effects.

Frequency

Once daily

With Food

Take on an empty stomach or with a light meal. Avoid high-fat meals.

Alcohol

Avoid alcohol — worsens CNS side effects

Missed Dose

Take as soon as remembered. If within 4 hours of next dose, skip. Never double dose.

FAQ

Frequently Asked Questions

Why do I need to take Efcure 200 mg Tablets at bedtime?

Efavirenz causes dizziness and vivid dreams in many patients, especially during the first few weeks. Taking it at bedtime means you sleep through most side effects. They typically lessen after 2–4 weeks.

Can Efavirenz cause mood changes?

Yes. Efavirenz is known to cause neuropsychiatric effects including depression, anxiety, and rarely suicidal thoughts. Report any persistent mood changes to your doctor immediately.

Is Efcure 200 mg Tablets safe to take during pregnancy?

Efavirenz should be avoided in the first trimester if possible due to evidence of neural tube defects in animal studies. Discuss alternatives with your HIV specialist if you are pregnant or planning a pregnancy.

How long before Efavirenz controls my viral load?

Most patients achieve significant viral suppression within 12–24 weeks. Consistent daily dosing without missed doses is essential for long-term virological success.

Drug Interactions

Drug / Substance	Effect	Action
