What Efafirenz Aurobindo is and what it is used for

Efavirenz Aurobindo, which contains the active substance efavirenz, belongs to a group of medicines called non-nucleoside reverse transcriptase inhibitors (NNRTIs). It is an antiretroviral drug for human immunodeficiency virus ( HIV- 1) infection that works by reducing the amount of virus in the blood. The drug is used by adults, adolescents, and children who are 3 months and older and who weigh at least 3.5 kg.

Your doctor has prescribed Efavirenz Aurobindo to you because you have HIV – infection. Taking Efavirenz Aurobindo in combination with other antiretroviral medicines reduces the amount of virus in the blood. This strengthens your immune system and reduces the risk of developing illnesses linked to HIV – infection.

Efavirenz contained in Efavirenz Aurobindo may also be approved for the treatment of other conditions not mentioned in this product information. Ask your doctor, pharmacist or other healthcare professional if you have any further questions and always follow their instructions.

How to use Efavirenz Aurobindo

Always take this medicine exactly as your doctor or pharmacist has told you. Ask your doctor or pharmacist if you are unsure. Your doctor will tell you which dose to take.

  • Dose one for adults is 600 mg once daily.
  • If you are taking certain other medicines at the same time, the dose of Efavirenz Aurobindo may need to be increased or decreased (see Other medicines and Efavirenz Aurobindo).
  • Efavirenz Aurobindo is taken by mouth. Efavirenz Aurobindo is recommended to be taken on an empty stomach, preferably at bedtime. This can reduce the symptoms of certain side effects (such as dizziness and drowsiness). By fasting, the stomach is usually meant 1 hour before or 2 hours after a meal.

If you have ingested too much medicine or if e.g. If a child has inadvertently ingested the medicine, contact a doctor, hospital, or the Poison Information Center for risk assessment and advice. Bring the medicine package with you so you can account for what you have taken.

If you stop using Efavirenz Aurobindo

When your Efavirenz Aurobindo tablets start to run out , make sure you get more from your doctor or pharmacist. This is very important because the amount of virus can start to increase as soon as you stop taking the medicine, even if it is only for a short time. The virus can then become more difficult to treat.

If you have any further questions on the use of this product, ask your doctor, pharmacist or nurse.

4. Possible side effects

Like all medicines, this medicine can cause side effects , although not everybody gets them.

In the treatment of HIV – infection, it is not always possible to tell whether some of the unwanted effects are caused by Efavirenz Aurobindo, other medicines you take at the same time, or by the HIV -sjukdomen.

During HIV treatment, weight gain and increased levels of lipids and glucose in the blood may occur.

This is partly related to restored health and lifestyle, but when it comes to blood lipids, there can sometimes be a connection with HIV drugs. The doctor will perform tests to find such changes.

The most notable side effects reported with efavirenz in combination with other HIVmedicines are skin rashes and central nervous system symptoms .

Always consult your doctor if you get a rash, as some rashes can be severe. In most cases, the rash disappears without the need to change treatment with Efavirenz Aurobindo. The rash is more common in children than in adults treated with efavirenz.

The symptoms of the central nervous system usually appear at the beginning of the treatment, but usually decrease during the first weeks. In one study, central nervous system symptoms often appeared during the first 1-3 hours after a dose . If you are affected by symptoms, your doctor may suggest that you take Efavirenz Aurobindo at bedtime and on an empty stomach. Some patients may have more severe symptoms that affect their mood or ability to think clearly. Some patients have committed suicide. The problems tend to occur more often in those who have previously had a mental illness. Always tell your doctor immediately if you get these symptoms or other side effects while taking Efavirenz Aurobindo.
