What Kind of Medicine Is Avatrombopag?
Avatrombopag is a prescription medicine designed to raise your blood platelet count when it drops too low. You might wonder what blood platelets actually do in your body. They are tiny cell fragments in your blood that help stop bleeding when you get a cut or injury.
Certain medical conditions can cause your platelet count to fall to unsafe levels. The two most common reasons include:
- Chronic liver disease that affects how your body and bone marrow function.
- Immune thrombocytopenia (ITP), a condition where your immune system mistakenly attacks and destroys your platelets.
When your platelet count is low, even a minor injury can lead to serious bleeding. Avatrombopag works by telling your bone marrow to make more blood platelets. This helps lower your risk of dangerous bleeding episodes.
Important Things to Tell Your Doctor Before Starting
Before you take your first dose, your doctor will ask you several health questions. Sharing your full medical history with your doctor is essential for your safety.
| Information to Share | Why It Matters |
|---|---|
| History of blood clots | This medicine can slightly raise the chance of blood clots. Your doctor needs to know if you had clots before. |
| Protein C or Protein S deficiency | These natural proteins help control blood clotting. Low levels mean clots can form much more easily. |
| Allergies to foods or medicines | This ensures you are not allergic to avatrombopag or any inactive ingredients inside the tablets. |
| Pregnancy or breastfeeding | Safety data during pregnancy and lactation is limited. You must discuss potential risks with your doctor. |
How to Use This Medicine Properly
Taking this medicine correctly is very straightforward. However, following your doctor instructions precisely is vital.
- Swallow the tablet whole with a glass of water.
- Always take your dose with a meal. Do not take this medicine on an empty stomach.
- Try to take your dose at the same time every day. This keeps a steady level of medicine in your body.
- Keep taking the medicine until your doctor tells you to stop. Do not stop suddenly just because you feel better.
What to Do If You Miss a Dose
If you forget to take your dose on time, take it as soon as you remember. But if it is almost time for your next scheduled dose, skip the missed dose entirely. Just take your next dose at the normal time.
Never take a double dose to make up for a missed tablet. Taking two doses at once can cause unwanted problems.
What Happens If You Take Too Much?
If you think you or someone else has taken too many avatrombopag tablets by mistake, act quickly. Go straight to the nearest hospital emergency department (ER / A&E). If you are in the US or Canada, call 911. If you are in the UK, call 999 or contact your local poison control center right away.
Important Note: This medicine was prescribed specifically for you. Never share your tablets with anyone else, even if they have low platelet counts too.
Other Things That Can Interact With This Medicine
Some other medicines and substances can react with avatrombopag. These interactions can change how well the medicine works or increase your risk of side effects. Common examples include:
- Certain antifungal medicines, such as fluconazole or itraconazole.
- Rifampin, which is a medicine used to treat tuberculosis.
This list does not include every possible interaction. Tell your doctor about every product you take. This includes prescription drugs, over-the-counter products, vitamins, herbal supplements, and traditional remedies. Let your doctor know if you smoke or drink alcohol regularly as well.
