Pharmacist tips for Tonmya (cyclobenzaprine)
- Take Tonmya (cyclobenzaprine) at bedtime at the same time each night, after brushing your teeth. This helps improve sleep and lowers daytime drowsiness.
- Take a few sips of water before taking Tonmya (cyclobenzaprine). A moist mouth helps the tablet dissolve under your tongue and might reduce mouth side effects.
- Place Tonmya (cyclobenzaprine) under your tongue and let it fully dissolve. Don’t swallow, chew, or crush it so it can work the right way.
- Don’t eat or drink for at least 15 minutes after Tonmya (cyclobenzaprine) dissolves. Try to avoid hot, cold, or acidic drinks until morning.

- Tonmya (cyclobenzaprine) can make you sleepy. Wait to drive or use machinery until you know how the medication affects you.
- Tell your care team about all medications and supplements you take before using Tonmya (cyclobenzaprine). Some medications, like certain antidepressants, opioids, and migraine medications can raise your risk of serotonin syndrome or other problems.
- Don’t take Tonmya (cyclobenzaprine) with monoamine oxidase inhibitors (MAOIs) or within 14 days of stopping one. This combination can be life-threatening.
- Avoid alcohol while taking Tonmya (cyclobenzaprine), since the combination can make you very sleepy, dizzy, and slow your breathing.

Cyclobenzaprine (the active ingredient in Tonmya (cyclobenzaprine)), is related to tricyclic antidepressants (TCAs), which have been linked to heart rhythm problems, heart attack, and stroke. These medications can also lower the seizure threshold, making seizures more likely in some people.
Get medical help right away if you have chest pain, shortness of breath, severe dizziness, fainting, or stroke-like symptoms. Tell your care team if you have a history of seizures so they can decide if this medication is safe for you or monitor you more closely.

Before starting Tonmya (cyclobenzaprine), talk to your prescriber if you have glaucoma, high eye pressure, or trouble urinating. This medication can make these problems worse. Your prescriber can help decide if it's safe for you and might monitor you more closely during treatment.
Drowsiness and slowed thinking
- Risk factors: Drinking alcohol | Taking other medications that cause drowsiness | Over 65 years old
Tonmya (cyclobenzaprine) can make you feel sleepy and slow your reaction time. It can also make it harder to focus. These side effects are more likely to happen if you're over 65 years old or take other medications that cause drowsiness.
Avoid driving, using machines, or doing tasks that need focus until you know how Tonmya (cyclobenzaprine) affects you. Don't drink alcohol while taking this medication since it can make these side effects worse. Talk to your prescriber if these side effects bother you or make daily activities hard.
Mouth side effects
Mouth numbness, tingling, discomfort, irritation, sores, or pain can happen with Tonmya (cyclobenzaprine). They usually start within minutes after dosing. Most are mild and last less than an hour, but some can be more severe and affect a larger area of your mouth.
Take a few sips of water before using Tonmya (cyclobenzaprine) to help reduce numbness, and avoid eating or drinking for 15 minutes after. Tell your care team if you have severe pain, large areas of irritation, or trouble eating, drinking, or swallowing. They might tell you to stop the medication.
