About Teefamc 200mg/300mg/600mg Tablet

Teefamc 200mg/300mg/600mg Tablet is a prescription tablet used to treat Human Immunodeficiency Virus type 1 (HIV-1) infection in adults and eligible children. It functions as a complete treatment regimen to control the virus and support the immune system. This medicine is not a cure for HIV-1 or AIDS, but it helps manage the condition long-term by keeping the viral load low.

For this medicine to work effectively, it must be taken consistently once a day, exactly as directed by your doctor. Taking it at bedtime on an empty stomach is highly recommended, as this timing helps minimise dizziness and sleep-related side effects. Adopting a balanced diet and avoiding high-fat meals around your dosing time can further support successful treatment results.

Some patients may experience mild side effects like trouble sleeping, headache, or mild dizziness when starting treatment. However, you must consult your doctor immediately if you experience serious symptoms such as signs of liver damage, deep depression, or a severe, painful skin rash.

Do not take this if you have a known severe allergy to any of its components or if you suffer from severe liver disease. Before starting this treatment, tell your doctor if you have a history of kidney disease, mental health disorders, or Hepatitis B infection. Your doctor may perform blood tests, including resistance testing, before starting treatment to ensure this medicine is suitable and likely to work effectively against your HIV infection. 

Teefamc 200mg/300mg/600mg Tablet can interact with several other prescription drugs, alcohol, and herbal supplements like St. John's Wort, which can reduce its effectiveness or increase the risk of harmful side effects. It is highly important for pregnant women, breastfeeding mothers, and older adults to consult their healthcare provider before using this medicine.

Uses of Teefamc 200mg/300mg/600mg Tablet

Teefamc 200mg/300mg/600mg Tablet is used for the following: 

  • HIV-1 Infection: Teefamc 200mg/300mg/600mg Tablet is used as a complete daily regimen to treat HIV-1 infection, helping to reduce the amount of the virus in the body so your immune system can function better.

Key Benefits

Teefamc 200mg/300mg/600mg Tablet offers the following benefits in the management of HIV-1 infection:

  • Simplified Treatment Regimen: By combining multiple viral-fighting medicines into a single daily tablet, Teefamc 200mg/300mg/600mg Tablet simplifies your daily routine and reduces the number of pills you need to take each day. This makes it much easier to stay consistent with your treatment, which is key to keeping the virus under control.
  • Supports Immune System Health: This medicine helps lower the level of HIV in your blood to undetectable levels. As the viral load drops, your body's infection-fighting cells (CD4 cells) can recover and grow stronger, significantly reducing your risk of developing infections or other complications associated with HIV.

Directions for Use

  • Take Teefamc 200mg/300mg/600mg Tablet on an empty stomach 1 hour before or 2 hours after food.
  • Teefamc 200mg/300mg/600mg Tablet should be taken once daily, preferably at bedtime.
  • Swallow it as a whole with a glass of water.
  • Do not break, crush, or chew it.

How Teefamc 200mg/300mg/600mg Tablet Works

Teefamc 200mg/300mg/600mg Tablet contains emtricitabine, tenofovir disoproxil fumarate, and efavirenz, which work together to control HIV-1 infection by reducing the virus's ability to multiply in the body. Emtricitabine is a nucleoside reverse transcriptase inhibitor (NRTI), a type of antiviral medicine that blocks an enzyme HIV needs to make copies of itself. This helps reduce the amount of virus in the body and slows the progression of the infection.  Tenofovir disoproxil fumarate is a nucleotide reverse transcriptase inhibitor (NtRTI), a type of antiviral medicine that also blocks the same enzyme HIV uses to reproduce. By interfering with the virus's ability to make the genetic material it needs to reproduce, it prevents HIV from multiplying and spreading to new cells.  Efavirenz is a non-nucleoside reverse transcriptase inhibitor (NNRTI), a type of antiviral medicine that attaches to the enzyme at a different site and stops it from working properly. Together, these ingredients lower the viral load, help maintain immune function, and reduce the risk of HIV-related complications.
