Flexeril, also known by its generic name cyclobenzaprine, is a muscle relaxant often prescribed to treat muscle spasms associated with painful musculoskeletal conditions like fibromyalgia or spinal cord injuries. It's one of the most commonly used medications for these conditions and has a long history of helping many people manage their pain.

What is Flexeril?

Flexeril (cyclobenzaprine) is a muscle relaxant. It works by blocking pain signals that are sent to your brain. Flexeril is used together with rest and physical therapy to treat skeletal muscle conditions such as pain or injury. Flexeril may also be used for purposes not listed in this medication guide. You should not take Flexeril if you have recently had a heart attack, or if you have certain heart rhythm disorders. Do not use Flexeril if you have taken an MAO inhibitor in the past 14 days, such as isocarboxazid, linezolid, methylene blue injection, phenelzine, rasagiline, selegiline, tranylcypromine, and others. 

How does Flexeril work?

Flexeril works by inhibiting the reuptake of the neurotransmitter norepinephrine in the brain. This action results in a decrease in muscle spasms and pain. It is thought to work by affecting the transmission of signals between nerve cells in the brain. Flexeril is used to treat muscle spasms and pain associated with conditions such as multiple sclerosis, cerebral palsy, and spinal cord injuries.

The usual adult dose of Flexeril is 5 mg three times daily. The maximum recommended dose is 20 mg per day. Flexeril should be taken with food or milk to decrease stomach upset. Flexeril may interact with other medications such as antidepressants, blood pressure medications, and seizure medications.

What are the uses of Flexeril?

Flexeril is a muscle relaxant that is commonly used to treat spasms, strains, and other conditions that cause muscle pain. It is also sometimes used to treat migraines and other types of headaches. Flexeril works by blocking certain nerve signals that are responsible for causing muscle pain. This can help to reduce pain and inflammation in the muscles. Flexeril is available in both oral and injectable forms. The oral form is usually taken three times a day, while the injectable form is usually given once a day. Flexeril can cause side effects such as drowsiness, dizziness, and nausea. These side effects are typically mild and go away on their own after a few days of treatment. 

What are the side effects of Flexeril?

  • The most common side effects of Flexeril are drowsiness, dizziness, headache, tiredness, blurred vision, upset stomach, constipation, dry mouth, and difficulty urinating. These side effects usually go away after a few days as your body adjusts to the medication.
