Flexeril Oral: Uses, Side Effects, Interactions, Pictures, Warnings & Dosing
The liver is responsible for most of cyclobenzaprine’s metabolism and excretion in the urine. People whose livers aren’t working properly or who take medicines that increase liver enzymes are at risk of developing a drug accumulation. Knowing a drug’s half-life is crucial for effective management and dosing considerations; cyclobenzaprine is no exception.
Cyclobenzaprine did not demonstrate mutagenic activity in the male mouse at dose levels of up to 20 times the human dose. The plasma concentration of cyclobenzaprine is increased in patients with hepatic impairment (see CLINICAL PHARMACOLOGY, Pharmacokinetics, Hepatic Impairment). For most patients, the recommended dose of Flexeril is 5 mg three times a day. People should avoid tasks that necessitate alertness until they know how Flexeril will affect them.

Cyclobenzaprine (CBP) has been studied in FM in a number of randomized trials employing doses of 10–40 mg per day, with mixed results2,3,4,5,6,7. CBP is approved by the US Food and Drug Administration (FDA) for treating muscle spasm, which is not a feature of FM. Of 37 patients with FM in the screened population, 36 were randomized and treated in this 8-week, double-blind, placebo-controlled, dose-escalating study of VLD CBP 1–4 mg at bedtime. Cyclobenzaprine is a prescription medication used to treat muscle spasms in the short term. Flexeril, Amrix, and Fexmid are some of the brand names for cyclobenzaprine. It is structurally similar to the tricyclic antidepressants and adverse effects similar to those seen with the tricyclic antidepressants are therefore to be expected.

- It is also sometimes prescribed off-label to treat fibromyalgia pain.
- Check the labels on all your medicines (such as allergy or cough-and-cold products) because they may contain ingredients that cause drowsiness.
- Antispastic medications are effective in treating spasticity, but high doses can lead to unwanted side effects.
Flexeril abuse can also end up leading to dangerously slow respiration. When Flexeril and alcohol are mixed, however, these qualities can actually end up overlapping, making the potentially fatal risk of low respiration even more likely to occur. The alcohol also increases the side effects of cyclobenzaprine.

You should avoid operating machinery or driving a vehicle when taking this medication. Cyclobenzaprine is considered a skeletal muscle relaxant because of the way it affects the body’s nervous system. Once the drug enters your body, it triggers your brain and nervous system to relax different muscles in the body, simultaneously relieving the pain and discomfort you feel. Muscle relaxers such as these act like a depressant for your body’s central nervous system. This causes a sedative effect and prevents your nerves from sending pain signals to your brain.
Each endpoint consisted of a score on a 5-point rating scale (from 0 or worst outcome to 4 or best outcome).
