What Is Asenapine Sublingual Tablet and How Do You Take It Safely?

If your doctor recently prescribed asenapine for you or a loved one, you probably have many questions about how it works. Feeling uncertain when starting a new medicine is completely normal. Having clear and simple information helps you feel confident and in control of your health journey.

Asenapine is a prescription medicine that helps manage specific mental health conditions by balancing natural chemicals in your brain. Taking it correctly is very important for your health and safety. Let us walk through everything you need to know about this medicine in simple, friendly terms.

What Is Asenapine?

Simply put, asenapine is a prescription medicine used to treat specific mental health conditions. Doctors most commonly prescribe it for schizophrenia and bipolar disorder. These conditions can change how you think, feel, and act every day.

Your brain relies on natural chemical messengers like dopamine and serotonin to regulate your mood, thoughts, and behavior. When these chemical messengers fall out of balance, mental health challenges can happen. Asenapine helps bring these brain chemicals back into balance, which stabilizes your mood and thoughts over time. This medicine belongs to a group of drugs called antipsychotics.

How to Use This Medicine Correctly

This is not a regular pill that you swallow with a glass of water. It is a special sublingual tablet designed to dissolve underneath your tongue. Follow these step-by-step instructions carefully to get the best results.

1. Wash and dry your hands thoroughly before touching the tablet packet.
2. Keep the tablet inside its sealed blister pack until the exact moment you are ready to take it.
3. When you are ready, peel open the pack carefully and take out the tablet. If the tablet breaks or crumbles, throw it away and open a fresh new tablet.
4. Place the intact tablet gently underneath your tongue.
5. Allow the tablet to dissolve completely. This usually takes only a short time. Once dissolved, you may swallow your saliva naturally.
6. Never cut, crush, chew, or swallow the tablet whole.
7. Most important rule: After the tablet dissolves, wait at least 10 minutes before eating or drinking anything.
8. Take your medicine at the exact times your doctor prescribed. Never stop taking it on your own.

What If You Miss a Dose?

If you forget to take your scheduled dose, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose entirely and stay on your normal routine. Never take two doses at the same time to make up for a missed one.

What If You Take Too Much?

If you think you have taken too much medicine, try to stay calm and act quickly. In the US, call Poison Control right away at 1-800-222-1222 or call 911. In the UK, call 999 or NHS 111. If you are in another country, contact your local emergency number right away or go straight to the nearest hospital Emergency Department (ER or A&E).
