What you need to know about an important drug in HIV treatment (Emtricitabine; Rilpivirine; Tenofovir)

Living with HIV can be challenging at times, but you know that with the right treatment, you can live a normal, healthy life. It's important to understand the medications you're taking during this treatment journey. Today, we're talking about a special combination of three antiretroviral drugs that can help control HIV. Let's take a look at what it is, how it works, and what you need to be aware of.

Let's find out exactly what this medicine is.

Simply put, this is a combination of three medications. That is, all three antiviral drugs , Emtricitabine, Rilpivirine, and Tenofovir Disoproxil Fumarate, are contained in one pill. In our country, this medicine can be found under the brand name `Complera`.

Its main function is to reduce the amount of HIV virus (viral load) in your body, strengthen your immune system, and help you stay healthy.

Remember: This medicine is a treatment for HIV, not a cure. Also, this medicine reduces the risk of transmitting HIV to others, but does not completely prevent it. Therefore, it is very important to continue to follow safe methods.

Things you need to tell your doctor before starting medication

Before deciding if this medication is right for you, your doctor will need to know your complete health history. Be sure to tell your doctor if you have any of the following conditions:

Your situation Why is it important to inform the doctor?
Bone problems (e.g. osteoporosis) The drug Tenofovir can sometimes affect bone density.
Kidney disease Since these medications are excreted from the body through the kidneys, it is essential to be aware of your kidney function.
Liver disease, especially Hepatitis B Hepatitis B symptoms may worsen when this medication is stopped. Liver function may also be affected.
Depression or suicidal thoughts The doctor should be aware of some of the ingredients in this medication, as they can cause mood changes.
Heart disease It is important for the doctor to be aware of certain heart conditions.
Allergies to other medications, foods, or substances This is important to know if you are allergic to anything in this medicine.
Being pregnant or expecting a baby You should discuss the use of this medication during pregnancy with your doctor.
Breastfeeding Breastfeeding is not recommended for HIV-infected mothers, so talk to your doctor about this as well.

How should I use the medicine?

To get the most out of this medicine, it is very important to use it correctly.

  • Take with food: Take this pill with a glass of water with a meal . Do not take it on an empty stomach. Rilpivirine is best absorbed by the body when taken with food.
  • Take it on time: Make it a habit to take your medicine at the same time every day. This will help keep the levels of the medicine in your blood consistent.
  • Don't skip doses: The most important thing in HIV treatment is to take your medication without missing a single dose. Even if you feel better, don't stop taking your medication until your doctor tells you to.
  • Why is it not good to skip doses? If you skip doses, the virus can develop resistance to this medication. If that happens, it will be harder to control the virus with this medication and other HIV medications.

What if I miss a dose of medication?

If you forget to take a dose, take it as soon as you remember. However, if it is almost time for your next dose when you remember (for example, less than 12 hours), skip the missed dose and take your next dose at the scheduled time. Never take a double dose.

What if I take too much medicine?

👩🏽‍⚕️ Additional questions (FAQs)

💬 What are Emtricitabine, Rilpivirine, and Tenofovir (Tenofovir / Odefsey, Complera) used for?

This is a combination of highly effective ART - Antiretroviral Therapy and the latest 3 drugs in a single pill (Single-tablet Regimen) available in pharmacies to combat the 'AIDS / HIV (Human Immunodeficiency Virus)' virus! After taking this pill once a day (with food), it inhibits the HIV virus from multiplying in the blood by 100%, controlling the virus to an undetectable viral load.

💬 How does this pill (Complera/Odefsey) completely stop the HIV virus from multiplying (transmitting)?

For a virus to replicate, it needs to enter one of our cells and copy its original message (RNA) into our DNA. The machine that the virus uses for this is the Reverse Transcriptase enzyme. This pill comes from both sides and puts 'wrong stuff (NRTI/Emtricitabine/Tenofovir)' and 'blocking stones (NNRTI/Rilpivirine)' into that machine. Then the HIV virus can never replicate again and it becomes weak.

💬 What are the main side effects and most dangerous dangers (Black Box Warning) that can occur when taking this HIV pill?

The biggest danger of these 3 drugs comes from Tenofovir! This can cause the patient's bones to melt/break easily (Bone loss / Osteoporosis) and the kidneys to stop completely (Lactic acidosis / Renal Toxicity). Also, do not take this pill if you are 'hungry without food (empty stomach)' for any reason! (Rilpivirine is not absorbed into the body, the drug does not work)!
