Proper use of asenapine
Use asenapine exactly as directed by your doctor. Do not use more of it, do not use it more often, and do not use it for a longer time than your doctor ordered. To do so may increase the chance of side effects.
Asenapine comes with patient instructions. Read and follow the instructions carefully. Ask your doctor if you have any questions.
To use the Secuado® skin patch:
- Asenapine should only be used on skin that is not irritated or injured. Do not put the patch in your mouth, chew it, or swallow it.
- Asenapine skin patches are packaged in sealed pouches. Do not cut open the foil pouch and remove the patch from the sealed pouch until you are ready to apply it.
- Apply the patch to a dry, flat skin area on your upper arm, upper back, abdomen, or hips. Choose a place where the skin is not very oily and is free of scars, cuts, burns, or irritation.
- Apply 1 patch to 1 application site every 24 hours. Rotate your application site every time you change a patch. Do not wear the patch longer than 24 hours.
- If the patch lifts or falls off after applying it, throw it away and apply a new patch in the same area.
- Do not shave the skin where you will apply the patch. You may cut the hair with a pair of scissors.
- Avoid bathing or swimming while wearing the patch. You may take a shower while using it.
The dose of asenapine will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of asenapine. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.

- For schizophrenia:
If you forget to wear or change a patch, put one on as soon as you can. If it is almost time to put on your next patch, wait until then to apply a new patch and skip the one you missed. Do not apply extra patches to make up for a missed dose.
Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Keep from freezing.
Keep out of the reach of children.
Do not keep outdated medicine or medicine no longer needed.
Ask your healthcare professional how you should dispose of any medicine you do not use.
To dispose of the Secuado® patch, fold the patch in half with the sticky side inside. If the patch has not been used, take it out of the pouch and remove the liner that covers the sticky side of the patch before folding it in half. Ask your pharmacist about the best way to dispose of patches you do not use. Do not flush the pouch or the protective liner down the toilet. Put them in a trash can.
Precautions while using asenapine
It is very important that your doctor check your progress at regular visits to make sure that asenapine is working properly. Blood and urine tests may be needed to check for any unwanted effects.
Asenapine may cause serious allergic reactions, including anaphylaxis. Anaphylaxis can be life-threatening and requires immediate medical attention. Call your doctor right away if you have a rash, itching, hoarseness, dizziness or lightheadedness, trouble breathing, trouble swallowing, or any swelling of your hands, face, tongue, or throat while you are using asenapine.
Tell your doctor right away if you have sores or blisters in the mouth, or numbness or tingling of the mouth or throat after using asenapine.
Check with your doctor right away if you have any of the following symptoms while using asenapine: convulsions (seizures), difficulty with breathing, a fast heartbeat, a high fever, high or low blood pressure, increased sweating, loss of bladder control, severe muscle stiffness, unusually pale skin, or tiredness. These could be symptoms of a serious condition called neuroleptic malignant syndrome (NMS).
Asenapine may cause tardive dyskinesia (a movement disorder). Check with your doctor right away if you have any of the following symptoms while using asenapine: lip smacking or puckering, puffing of the cheeks, rapid or worm-like movements of the tongue, uncontrolled chewing movements, or uncontrolled movements of the arms and legs.
For diabetic patients: Asenapine may affect your blood sugar levels. Check with your doctor right away if you have increased thirst or increased urination. If you notice a change in the results of your urine or blood sugar tests, or if you have any questions, check with your doctor.
Asenapine may increase your weight. Your doctor may need to check your weight on a regular basis while you are using asenapine. Talk to your doctor about ways to prevent weight gain.
Dizziness, lightheadedness, or fainting may occur, especially when you get up from a lying or sitting position suddenly. Getting up slowly may help. If this problem continues or gets worse, check with your doctor.
Asenapine can temporarily lower the number of white blood cells in your blood, increasing the chance of getting an infection. If you can, avoid people with infections. Check with your doctor right away if you think you are getting an infection, or if you have a fever or chills, cough or hoarseness, lower back or side pain, or painful or difficult urination.
Asenapine can cause changes in the heart rhythm, such as a condition called QT prolongation. It may change the way your heart beats and cause fainting or serious side effects. Contact your doctor right away if you have any symptoms of heart rhythm problems, such as fast, pounding, or irregular heartbeats.
Asenapine may cause dizziness, drowsiness, trouble with thinking, or trouble with controlling body movements. Make sure you know how you react to asenapine before you drive, use machines, or do anything else that requires you to be alert, well-coordinated, or able to think well.
Asenapine might reduce how much you sweat. Your body could get too hot if you do not sweat enough. If your body gets too hot, you might feel dizzy, weak, tired, or confused. You might vomit or have an upset stomach. Do not get too hot while you are exercising. Avoid places that are very hot. Call your doctor if you are too hot and cannot cool down.
Heat can cause the asenapine in the patch to be absorbed into your body faster. This may increase the chance of serious side effects or an overdose. While you are using asenapine, do not use a heating pad, electric blanket, heat or tanning lamps, sauna, a sunlamp, or a heated water bed, and do not sunbathe, or take long baths or showers in hot water.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
