Product Description

Efavir is a branded formulation of efavirenz, a non-nucleoside reverse transcriptase inhibitor used in the treatment of HIV-1 infection. It is not used alone but always as part of combination antiretroviral therapy alongside other antiviral medicines to control the virus, maintain or improve immune function and reduce the risk of HIV-related illnesses. Efavir is available in capsule strengths of 200 mg and 600 mg, each pack containing 30 capsules, allowing prescribers to tailor the dosing regimen to individual patient needs and local guidelines.

The 600 mg strength of Efavir is commonly used for once-daily dosing in adults and adolescents when efavirenz is part of a complete HIV regimen that also includes nucleoside or nucleotide reverse transcriptase inhibitors and sometimes additional agents. The 200 mg strength may be used in step-up dosing, in body-weight–based schedules or in special situations such as dose adjustments for drug interactions, hepatic impairment or paediatric use under specialist supervision. Efavir is generally taken at bedtime to help reduce certain central nervous system side effects associated with efavirenz.

Generic Meds Mart supplies Efavir 200 mg and Efavir 600 mg efavirenz capsules in original manufacturer packaging from licensed distributors. Each pack clearly displays the brand name, strength, generic name, batch number and expiry date so that healthcare providers can verify the product. Orders are dispatched in neutral outer packaging that does not reveal the nature of the contents, supporting privacy for people living with HIV while they access the medicines prescribed by their treating team.

Key Uses

Efavir is used for the treatment of HIV-1 infection in adults and adolescents, always in combination with other antiretroviral medicines. It is not a cure for HIV but helps to suppress viral replication, lowering the amount of virus in the blood (viral load) and supporting recovery or preservation of CD4 immune cells. By maintaining viral suppression and good adherence over the long term, effective antiretroviral therapy reduces the risk of opportunistic infections, HIV-related illnesses and onward transmission.

Efavir-containing regimens may be chosen according to local guidelines, availability and individual patient factors, including prior treatment history, resistance test results, potential drug interactions and co-existing conditions such as tuberculosis, hepatitis or psychiatric illness. The decision to include efavirenz, and the choice between 200 mg and 600 mg capsules, is made by an HIV specialist based on these clinical considerations. Patients should not start, change or stop Efavir or any part of their antiretroviral regimen without professional guidance.

How Efavirenz Works in Antiviral Therapy

Efavirenz, the active ingredient in Efavir capsules, belongs to the class of non-nucleoside reverse transcriptase inhibitors. HIV-1 uses an enzyme called reverse transcriptase to copy its genetic material from RNA into DNA inside infected cells. This step is essential for the virus to integrate into the host genome and produce new virus particles. Efavirenz binds to a specific site on the reverse transcriptase enzyme, causing a change in its shape and interfering with its function.

By allosterically inhibiting reverse transcriptase, efavirenz reduces the ability of HIV to replicate. When used together with other antiretroviral agents that target different stages of the viral life cycle, efavirenz contributes to a potent and durable suppression of viral load. Continuous suppression helps protect the immune system and decreases the risk of resistance mutations emerging. However, maintaining this benefit requires good adherence, meaning that doses of Efavir and companion antiretrovirals are taken as prescribed and not frequently missed.

Dosage & Administration

Efavir dosing and schedule are determined by an HIV specialist. In many adult treatment protocols, efavirenz is given as 600 mg once daily, typically at bedtime, in combination with other antiretroviral medicines. Taking Efavir at night and on an empty stomach or with a light snack may help reduce some central nervous system side effects such as dizziness, abnormal dreams or feeling “spaced out”. Heavier or high-fat meals can increase efavirenz levels and make these effects more pronounced.

The 200 mg capsule strength allows for flexible dosing strategies. It may be used to build up to a full 600 mg dose, to adjust the total daily dose in certain drug interaction scenarios or in weight-based regimens in adolescents when recommended by treatment guidelines. Efavir capsules should be swallowed whole with water and should not be opened or crushed unless a specialist provides specific instructions. Patients should follow the instructions provided by their HIV clinic exactly and should not change the dose or timing without medical advice.

Precautions

Before starting Efavir, your healthcare team will review your medical history, including any liver problems, psychiatric conditions, seizure disorders, heart rhythm issues, pregnancy plans or other significant health concerns. Efavirenz can affect liver function, so baseline and periodic liver enzyme tests are usually recommended, especially in people with hepatitis B or C co-infection. Central nervous system effects, including insomnia, abnormal dreams, dizziness, mood changes or depression, can occur and are sometimes more common in the first weeks of therapy. Patients with a history of severe psychiatric illness should be monitored closely, and any worrying symptoms should be reported promptly.

Efavirenz interacts with many other medicines, including certain antiretrovirals, tuberculosis drugs such as rifampicin, antifungals, some antidepressants, hormonal contraceptives and herbal remedies like St John’s wort. These interactions can alter drug levels and impact safety or effectiveness. It is essential to inform your doctor and pharmacist about all medicines, supplements and traditional or herbal products you use. Efavirenz can reduce the effectiveness of hormonal contraception, so reliable barrier methods or non-hormonal contraception are usually recommended. Pregnancy considerations, including potential risks in early pregnancy, should be discussed in detail with your HIV specialist.

Efavirenz Side Effects

Common side effects

Common side effects of Efavir include dizziness, drowsiness, difficulty concentrating, unusual dreams or nightmares, trouble sleeping, tiredness and a feeling of being “spaced out”, especially soon after starting treatment. Some people also experience rash, mild nausea, stomach discomfort or changes in appetite. These effects are often most noticeable in the first days or weeks of therapy and may lessen with time as the body adjusts. Taking Efavir at bedtime and avoiding high-fat evening meals can sometimes help reduce central nervous system symptoms. If common side effects remain distressing or interfere with daily functioning, you should discuss them with your HIV clinic.

Serious side effects

More serious side effects are less common but require immediate medical attention. These include severe rash or rash with blistering, mouth sores, fever or involvement of the eyes, which can signal serious skin reactions; marked mood changes, deep depression, suicidal thoughts or unusual behaviour; severe liver problems with symptoms such as yellowing of the skin or eyes, dark urine, significant abdominal pain or persistent nausea; and signs of severe allergic reaction such as swelling of the face, lips or tongue with difficulty breathing. Any seizure activity, persistent confusion or signs of severe mental health disturbance while taking Efavir should be treated as urgent. If you experience any of these serious symptoms, seek medical care immediately and inform your HIV specialist.

Storage

Efavir capsules should be stored at room temperature, generally below 25–30 degrees Celsius, in a dry place away from direct heat and moisture. Keep the capsules in their original bottle or blister pack until the time of use to protect them from humidity and mix-ups with other medicines. Do not store Efavir in the bathroom or near sinks. Always keep the medicine out of sight and reach of children and pets. Do not use Efavir after the expiry date printed on the packaging, and consult your pharmacist or clinic about safe disposal of expired or unused capsules.

Order Now

Before ordering Efavir 200 mg or 600 mg from Generic Meds Mart, you should have a confirmed diagnosis of HIV-1 infection, a clear treatment plan and a prescription or recommendation from your HIV specialist that specifically includes efavirenz at the appropriate dose. Your clinician will take into account your viral load, CD4 count, resistance profile, co-infections, other medicines and potential pregnancy before deciding if Efavir-based therapy is right for you. Once you have this medical guidance, you can select the correct Efavir strength and quantity to match your regimen and add it to your cart for secure checkout.

You should never start or stop Efavir, change from 200 mg to 600 mg, or alter your dosing schedule without discussing it with your HIV clinic. Missing doses or making unplanned changes to therapy can lead to viral rebound and resistance, which may limit future treatment options. If you experience new symptoms, side effects or difficulties with adherence while taking Efavir, contact your healthcare team promptly for advice rather than adjusting the medicine yourself. Generic Meds Mart exists to support medicine access according to your specialist’s plan, not to replace professional HIV care.

FAQ about Efavir (Efavirenz)

Q1: Is Efavir a complete treatment for HIV?

Efavir is not a complete treatment on its own. It contains efavirenz, an NNRTI that must be used together with other antiretroviral medicines as part of a combination regimen. Your HIV specialist will design a complete treatment plan that includes Efavir with other drugs to suppress the virus effectively and reduce the risk of resistance.

Q2: When is the best time to take Efavir capsules?

Efavir is often taken once daily at bedtime. Taking it at night and avoiding heavy, high-fat meals near the dose may help reduce certain central nervous system side effects such as dizziness, abnormal dreams or feeling “high” or “foggy”. Your clinic will give you specific advice about timing based on your overall regimen and lifestyle.

Q3: Can I drink alcohol while taking Efavir?

Occasional light alcohol use may be allowed for some patients, but alcohol can worsen dizziness, drowsiness and mood changes and may also affect liver health. Because both Efavir and alcohol can impact the liver and the central nervous system, it is important to discuss alcohol use honestly with your HIV specialist, who can advise what is safe in your situation.

Q4: What should I do if I miss a dose of Efavir?

If you forget a dose of Efavir and it has not been very long since your usual time, take it as soon as you remember, then continue with your normal schedule. If it is almost time for your next dose, skip the missed capsule and take the next one at the regular time. Do not double up to make up for a missed dose. Repeated missed doses can increase the risk of resistance, so talk to your clinic if adherence is difficult so they can help you find solutions.

Q5: Can Efavir be used during pregnancy?

The use of efavirenz in pregnancy requires careful consideration. In many settings, safer alternatives may be preferred during early pregnancy, while in others the benefits of continuing an effective regimen may outweigh potential risks. If you are pregnant or planning a pregnancy while taking Efavir, do not stop the medicine on your own, but contact your HIV specialist immediately so that your treatment can be reviewed and, if necessary, adjusted in a controlled way.
