What Does This Medicine Actually Do?
Simply put, this medicine combines two different active ingredients into one pill: Lamivudine and Tenofovir Disoproxil Fumarate. Both drugs belong to a family of medicines called antiretrovirals, which are designed to fight retroviruses like HIV.
The main job of this medicine is to stop the HIV virus from multiplying and spreading inside your body. By keeping the virus levels low, it protects your immune system from damage and helps you live a long, healthy life.
Please remember an important fact: This medicine does not cure HIV or AIDS. Even while taking this medicine, you can still pass the virus to someone else. Always use safe sex practices like condoms. Also, this medicine does not protect you against other sexually transmitted infections (STIs).
Things to Tell Your Doctor Before Starting This Medicine
Your safety and the success of your treatment depend on honesty. Before you start taking this medicine, make sure to tell your doctor about your complete medical history. Do not hide any details.
- Bone problems: Tell your doctor if you have ever had bone conditions, such as weak or thinning bones (osteoporosis).
- Kidney problems: Let your doctor know if you have any history of kidney disease or impaired kidney function.
- Liver problems: Inform your doctor if you have liver conditions, especially hepatitis B infection.
- Pancreatitis: Mention if you have ever suffered from inflammation of the pancreas in the past.
- Allergies: Tell your doctor if you are allergic to these active ingredients, or any other medicines, foods, or preservatives.
- Pregnancy: Let your doctor know if you are pregnant, planning to become pregnant, or trying to start a family soon.
- Breastfeeding: Inform your doctor if you are currently nursing or breastfeeding your baby.
Your doctor uses this important information to decide if this medicine is right for you or if your dosage needs adjustments.
How to Use This Medicine Correctly
To get the maximum benefit from your treatment, you must take your medicine exactly as prescribed by your doctor.
- Swallow the tablet whole with a full glass of water.
- You can take this medicine with or without food. However, if it upsets your stomach, taking it with a meal can help.
- The most important rule is to take your medicine at the exact time every single day without missing a dose. Missing doses allows the HIV virus to become resistant to the medicine, making future treatment much harder.
- Continue taking your medicine regularly until your doctor tells you to stop. Never stop taking it on your own just because you feel better.
What to Do If You Take Too Much
If you think you have taken more medicine than prescribed, act quickly. Go right away to the nearest hospital Emergency Room (ER) or A&E department. If you are in the US or Canada, call 911. If you are in the UK, call 999. You can also contact your local poison control center right away for emergency guidance.
What to Do If You Miss a Dose
If you forget to take your medicine, take the missed dose as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose entirely and continue with your regular schedule. Never take two doses at the same time to make up for a forgotten pill.
