Description
Efavir 200 (Efavirenz 200mg) Capsules
Efavir 200 contains efavirenz 200mg, an antiviral medicine in the non-nucleoside reverse transcriptase inhibitor (NNRTI) class. Efavirenz is used with other antiretroviral medicines to treat HIV-1 infection. The product shown here is Efavir 200 from Cipla and contains 30 capsules.
Efavir 200 Efavirenz: What Is It?
Efavir 200 is a prescription capsule containing efavirenz 200mg. The product shown in the image is manufactured by Cipla and contains 30 capsules.
Efavirenz belongs to the NNRTI class of antiretroviral medicines. It works by inhibiting HIV reverse transcriptase, an enzyme that HIV needs to replicate.
Because efavirenz is normally used with other HIV medicines, patients should follow the complete regimen prescribed by their healthcare professional.
Efavir 200 Efavirenz Uses
Efavir 200 contains efavirenz, which is used with other antiretroviral medicines to treat HIV-1 infection.
Efavirenz helps reduce HIV replication. Consequently, combination antiretroviral therapy can lower viral load and support immune function.
However, efavirenz does not cure HIV. Therefore, patients should continue their complete prescribed treatment unless their healthcare professional changes the regimen.
What Is Efavirenz Used For?
Efavirenz is primarily used as part of combination treatment for HIV-1 infection. It belongs to the NNRTI class.
Current U.S. labeling includes adults and pediatric patients at least 3 months old who weigh at least 3.5kg, with dosing determined according to age and body weight.
Importantly, efavirenz should not be used alone as HIV treatment. The current U.S. label specifically states that it must be given with other antiretroviral medicines.
How Does Efavir 200 Efavirenz Work?
Efavirenz inhibits HIV-1 reverse transcriptase. This enzyme helps HIV convert its genetic material into DNA.
By interfering with reverse transcriptase, efavirenz reduces the virus’s ability to reproduce. As a result, combination therapy can decrease HIV levels in the blood.
Nevertheless, efavirenz does not remove HIV from the body. Effective treatment therefore requires an appropriate antiretroviral regimen.
Efavir 200 Composition
- Active ingredient: Efavirenz
- Strength: 200mg
- Dosage form: Capsule
- Drug class: Non-nucleoside reverse transcriptase inhibitor

Efavirenz 200mg Dose
The correct efavirenz dose depends on age, body weight, other medicines, liver function, and the complete HIV treatment regimen.
For adults, current U.S. prescribing information recommends 600mg once daily.
Because this product contains 200mg per capsule, the 200mg strength may form part of a prescribed dosing combination. It should not be assumed that one 200mg capsule is the standard adult daily dose.
For pediatric patients, dosing depends on body weight. Certain drug interactions can also require dose adjustments.
For current prescribing information, review the DailyMed efavirenz prescribing information.
How to Take Efavir 200
Take Efavir exactly as prescribed by your healthcare professional.
- Efavirenz is generally taken once daily.
- Take it on an empty stomach.
- Taking it at bedtime may reduce the impact of some nervous-system side effects.
- Swallow capsules whole with liquid unless your healthcare professional provides capsule-sprinkle instructions.
- Take the other medicines in your HIV regimen as prescribed.
- Do not stop treatment without medical advice.
Current patient information recommends taking efavirenz at least 1 hour before or 2 hours after a meal. Therefore, follow the food instructions carefully.
Efavir 200 Efavirenz Side Effects
Efavirenz can cause side effects, particularly involving the nervous system during treatment.
Possible side effects include:
- Dizziness
- Headache
- Difficulty sleeping
- Unusual dreams
- Confusion
- Nausea
- Vomiting
- Difficulty concentrating
These effects can vary between individuals. Taking efavirenz at bedtime may make some nervous-system effects less bothersome.
Serious Efavirenz Side Effects
Efavirenz has important safety warnings. Serious reactions can involve the skin, liver, nervous system, mental health, or heart rhythm.
Seek prompt medical attention if you develop:
- Severe rash
- Blistering or peeling skin
- Swelling of the face
- Mouth sores
- Seizures
- Fainting
- Irregular heartbeat
- Severe confusion
- Hallucinations
- Severe depression or suicidal thoughts
- Yellowing of the skin or eyes
- Unusual bleeding or bruising
Efavirenz can also cause nervous-system problems that may persist or appear after long-term use. Therefore, report unusual neurological or mental-health symptoms promptly.
Efavirenz and Mental Health
Efavirenz can affect mood, behavior, sleep, and mental health.
Some people may experience abnormal dreams, confusion, anxiety, depression, hallucinations, or other changes in thinking.
For that reason, tell your healthcare professional about any history of depression, mental-health conditions, substance use, or seizures before starting treatment.
Efavirenz and Nervous System Effects
Dizziness, sleep problems, unusual dreams, and difficulty concentrating can occur with efavirenz.
These effects may be more noticeable when treatment begins. Consequently, avoid driving or operating machinery until you know how the medicine affects you.
Alcohol can also make certain nervous-system effects worse. Therefore, discuss alcohol use with your healthcare professional.
Efavir 200 Efavirenz and Food
Efavirenz capsules should generally be taken on an empty stomach.
Food can increase efavirenz exposure and may increase the frequency of certain adverse reactions. Therefore, taking the medicine at bedtime on an empty stomach can improve tolerability for some patients.
Efavirenz and HIV Treatment
Efavirenz is one component of combination antiretroviral therapy. Healthcare professionals combine medicines from different drug classes to suppress HIV replication effectively.
Current HIV treatment often favors newer regimens for many patients. However, efavirenz remains an established antiretroviral medicine and may be used in specific treatment situations.
For general information about HIV treatment, visit MedlinePlus HIV Medicines.
Efavirenz Emtricitabine Tenofovir
Efavirenz, emtricitabine, and tenofovir disoproxil fumarate have been combined in HIV treatment.
For example, the fixed-dose combination Atripla contains these three active ingredients. However, Efavir 200 contains efavirenz alone.
Therefore, Efavir 200 should not be treated as equivalent to a combination product containing efavirenz, emtricitabine, and tenofovir.
Efavirenz and Zidovudine
Efavirenz can be combined with nucleoside reverse transcriptase inhibitors such as zidovudine as part of an appropriate HIV treatment regimen.
However, current treatment recommendations depend on resistance, previous therapy, interactions, tolerability, and other clinical factors.
Therefore, patients should follow their current prescribed regimen rather than adding zidovudine independently.
Efavirenz and Rilpivirine
Rilpivirine is another NNRTI used for HIV treatment. However, efavirenz and rilpivirine are different medicines.
Because both medicines act on reverse transcriptase, combining them is not routinely appropriate. Instead, healthcare professionals select one suitable regimen based on current treatment guidelines and patient-specific factors.
Efavirenz and Raltegravir
Raltegravir belongs to a different HIV drug class called integrase strand transfer inhibitors (INSTIs).
Efavirenz and raltegravir can have different roles in HIV treatment. However, the combination and dosing should be determined by an HIV specialist based on the complete treatment plan.
Efavirenz Drug Interactions
Efavirenz has many clinically important drug interactions because it affects several drug-metabolizing enzymes.
Tell your doctor and pharmacist about every prescription medicine, over-the-counter product, vitamin, supplement, and herbal product you use.
Important interaction categories include:
- Certain antiretroviral medicines
- Some anticonvulsants
- Some antifungal medicines
- Warfarin and other medicines affected by enzyme induction
- Certain sedatives
- Some cholesterol medicines
- St. John’s wort
- Rifampin
- Voriconazole
Because interaction rules can be complex, do not start or stop another medicine without professional advice.
Efavirenz and St. John’s Wort
St. John’s wort can reduce efavirenz concentrations and may decrease treatment effectiveness.
Therefore, current patient information advises against starting St. John’s wort while taking efavirenz unless your healthcare professional specifically recommends it.
Efavirenz and Rifampin
Rifampin can lower efavirenz exposure.
For adults weighing at least 50kg, the current U.S. label recommends increasing efavirenz capsules to 800mg once daily when coadministered with rifampin.
Because this is a regimen-specific adjustment, patients should never change their efavirenz dose independently.
Efavirenz and Voriconazole
Efavirenz interacts with voriconazole in both directions. The current U.S. label recommends specific dose adjustments when the two medicines are used together.
Therefore, this combination requires careful prescribing and monitoring.
Efavir 200 Efavirenz and Liver Disease
Tell your healthcare professional if you have hepatitis, liver disease, or abnormal liver tests.
Current U.S. labeling recommends monitoring hepatic function before and during treatment. Efavirenz is not recommended in patients with moderate or severe hepatic impairment classified as Child-Pugh B or C.
Consequently, liver function can affect whether efavirenz is an appropriate treatment option.
Efavirenz and Heart Rhythm
Efavirenz can prolong the QT interval in some patients.
People with heart-rhythm problems or those taking other medicines that increase the risk of Torsade de Pointes may require an alternative treatment.
Tell your healthcare professional about fainting, irregular heartbeat, or known heart disease before starting efavirenz.
Efavirenz During Pregnancy
Tell your healthcare professional if you are pregnant, planning pregnancy, or may become pregnant.
Current U.S. patient information states that efavirenz may harm an unborn baby and provides specific pregnancy and contraception guidance. Therefore, people who are pregnant or may become pregnant should discuss treatment with their healthcare professional.
Do not stop HIV treatment independently because of pregnancy. Instead, discuss the safest complete antiretroviral regimen with an HIV specialist.
Efavirenz and Breastfeeding
Discuss breastfeeding with your healthcare professional before starting or continuing efavirenz.
HIV can be transmitted through breast milk, and medication exposure can also occur. Therefore, infant-feeding decisions should follow current medical guidance and local recommendations.
Can Efavir 200 Cure HIV?
No. Efavirenz does not cure HIV.
It reduces HIV replication as part of combination antiretroviral therapy. Effective treatment can lower viral load and help protect immune function.
Therefore, continue the complete prescribed HIV regimen unless your healthcare professional changes it.
What Happens If You Miss an Efavir 200 Dose?
If you miss a dose, take it when you remember unless it is almost time for the next dose.
If the next dose is near, skip the missed dose and continue your regular schedule. Do not take a double dose.
Maintaining consistent treatment is important because missed doses can increase the risk of treatment failure and resistance.
Can I Stop Efavir 200 When I Feel Better?
No. Do not stop efavirenz without medical advice.
HIV can rebound when treatment stops. In addition, inconsistent treatment can make HIV harder to control and may contribute to resistance.
If side effects concern you, speak with your healthcare professional rather than stopping the medicine independently.
