If you are being treated for HIV, your doctor may have prescribed you various medications. Among these, Indinavir is a very important medication. This article is intended to discuss this medication, how to use it, and what to be careful about in detail and simply. We hope that this information will be very useful to you.
What is this Indinavir?
Simply put, Indinavir is a drug that belongs to the class of antiretroviral drugs. It is used in combination with other drugs to control HIV infection.
It is important to remember that this medicine cannot completely cure HIV. However, it can help control the virus in the body and strengthen your immune system.
Also, when used correctly, this medicine can reduce the risk of transmitting the HIV virus to another person. Therefore, it is a very important medicine that can improve the quality of your life living with HIV.
Things to tell your doctor before taking medication
Before starting this medication, it is very important to tell your doctor about your complete health history. Don't hide anything, even the smallest details. Be sure to tell your doctor if you have any of the following conditions:
- Diabetes (Diabetes Mellitus)
- Bleeding disorders like hemophilia
- Kidney disease
- Liver disease
- If you have an allergic reaction to indinavir or any other medicine, food, or dye.
- If you are pregnant, trying to get pregnant, or breastfeeding (this is very important during HIV treatment)
How should I use the medicine?
The most important thing is to take the medicine exactly as the doctor says. In general, you should follow these instructions.
- Take this medicine with a glass of water.
- It is best to take it on an empty stomach , meaning one hour before or two hours after a meal.
- But if you have trouble taking it on an empty stomach, you can take it with a light meal, such as a piece of toast with some jam, a cup of coffee with less sugar, and some cornflakes. Talk to your doctor about this.
- Take the medicine at the prescribed time and at the prescribed intervals. Do not take it more often than the doctor tells you to.
Where the success of treatment depends
The biggest secret to the success of this treatment is taking the correct dose on time. Never skip a dose of the medicine. Even if you feel better, do not stop taking the medicine without the advice of your doctor. If you miss such doses, the HIV virus can become resistant not only to this medicine, but also to other medicines. That is a major obstacle to treatment.
What if I miss a medication appointment?
If it is more than 2 hours past the time you are supposed to take the medicine, skip the missed dose and take the next dose at the regular time. However, if it is less than 2 hours past the time you are supposed to take the medicine, take it as soon as you remember and take the next dose at the regular time. Do not take a double dose for any reason.
What if I take too much medicine?
If you have the slightest suspicion that you have taken more than the prescribed dose, immediately call the National Poisons Information Centre at the Colombo National Hospital, or go to the Emergency Treatment Unit (ETU) of the nearest hospital.
