Why is Sustiva prescribed?

Sustiva is prescribed for the treatment of HIV-1 infection. This medication is used in combination with other antiretroviral agents to reduce the amount of HIV in the body, slow the progression of the disease, and support immune system function. Sustiva is not a cure for HIV but helps manage the infection, delaying the progression to AIDS.

What does it do?

Sustiva works by inhibiting the enzyme responsible for producing prostaglandins. Prostaglandins are chemicals that trigger inflammation, pain, and swelling in the body. By blocking their production, Sustiva helps reduce both pain and inflammation.

How should I take it?

Sustiva should be taken exactly as prescribed by your healthcare provider. Typically, it is administered orally once daily, and it is often recommended to take it at bedtime to help minimize some of the central nervous system side effects that can occur (such as dizziness or vivid dreams). It is important to swallow the tablet whole with water. If the instructions specify taking it on an empty stomach or with food, it is essential to follow that guidance for optimal absorption and to reduce the risk of side effects.

What if I missed a dose?

If you miss a dose of Sustiva, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and resume your regular dose schedule. Do not double up on doses to make up for the one you missed.

What are the special precautions before taking Sustiva?

Before taking Sustiva, here are several important precautions to keep in mind:

Disclose all your current or past medical conditions to your doctor, particularly if you have:

• Liver disease
• Heart disease
• Long QT syndrome
• Seizure
• Mental illness

Avoid driving, operating machinery, or engaging in tasks requiring alertness while taking this medication until you can do so safely.

Do not share this medication with others, even if they have a similar condition, as it could lead to unforeseen health risks or adverse reactions.

If you are pregnant, considering pregnancy, or breastfeeding, consult your doctor to understand the potential risks and benefits of taking this medication.

Is it safe to take it with another drug?

Sustiva (Efavirenz) can interact with various medications, so it's important to check for potential interactions before taking it with another drug. Some interactions may increase side effects or reduce effectiveness.

Before taking Sustiva, consult your doctor if you are using any of the following medications:

• Antidepressants
• Certain antifungals
• High blood pressure medications
• Certain anti convulsants
• Heart problem medications

This is not a complete list of all the potential drug interactions, always consult your doctor or pharmacist before combining Sustiva with other medications to ensure safety.

How should I store it?

Sustiva should be stored in its original container at room temperature, ideally between 15°C and 30°C (59°F to 86°F). Keep the medication in a cool, dry place, away from direct sunlight, and ensure it is kept out of reach of children and pets. Always check the packaging for specific storage instructions and never use it past its expiration date.

What action should I take in case of overdose?

If you suspect an overdose of Sustiva (Efavirenz), it's important to act quickly and seek immediate medical attention. Contact emergency services or go to the nearest hospital. Overdose symptoms may include confusion, dizziness, hallucinations, agitation, or loss of consciousness.

Is it safe for pregnant or breastfeeding women?

Sustiva (Efavirenz) poses safety concerns for pregnant and breastfeeding women. It is not recommended during the first trimester due to potential birth defect risks, with some studies linking early use to an increased likelihood of neural tube defects. Women of childbearing potential should use effective contraception while taking Sustiva. Additionally, Efavirenz can transfer into breast milk, potentially affecting the infant, making caution necessary during breastfeeding.

If you are pregnant, planning to become pregnant, or breastfeeding, consult your healthcare provider for guidance on its use to ensure safety for both you and your baby.
