Cyclobenzaprine: Side Effects, dosage, uses, and more

Selection of a skeletal muscle relaxant should be individualized to the patient. If there are tender spots over the muscle or trigger points on physical examination, a skeletal muscle relaxant is a reasonable adjunct to analgesic treatment of low back pain. Skeletal muscle relaxants may also be used as an alternative to NSAIDs in patients who are at risk of gastrointestinal or renal complications. As mentioned above, there is not a significant difference between Robaxin, Fexmid, Amrix, and other muscle relaxants in terms of efficacy in treating acute low back pain, other musculoskeletal pain, and muscle spasms.

It’s important to thoroughly inform your doctor about all of your medical conditions because muscle relaxants might not be suitable for certain diseases and conditions. You should discuss the treatment options with your doctor. While all the medicines are effective, one specific muscle relaxant might work better than others for you. Flexeril (generic name cyclobenzaprine) was developed in the 1970s. Flexeril works on the central nervous system to reduce motor activity or muscle contractions, thus, relieving muscle spasms. Using drinks containing alcohol can increase your risk of dizziness, drowsiness, and decreased alertness from cyclobenzaprine.

However, one drug might be more effective for you than another. Robaxin is the brand name of the generic medication called methocarbamol. It was developed in the 1960s to treat pain and provide relief from muscle spasms. While its exact mechanism of action remains unclear, scientists believe Robaxin can help with pain and discomfort caused by musculoskeletal conditions by blocking the pain signals that are sent to the brain. It is also believed that Robaxin relaxes the muscle by having depressive effects on the central nervous system.

It occurred to me that it might work even better if I used a little more than I normally would. I waited until I had a couple of days when I would be at home, by myself. When I only took Flexeril 10mg, it produced a type of “hangover” effect the next day. I woke up in the morning and I took one 10mg tab of Flexeril, sat back and waited for the high.

It’s also not recommended that you take this muscle relaxer for more than 3 weeks. It is available in immediate-release tabletsof 5 milligrams, 7.5 milligrams, and 10 milligrams and extended-release capsules of 15 milligrams and 30 milligrams and is usually given three times daily. The extended-release formulation should be administered at the same time each day.

It can, however, reduce acute pain or discomfort that’s causing your insomnia and offer short-term relief for acute insomnia.
If the dosage is tampered with, that will end up causing greater cyclobenzaprine high.
In such patients FLEXERIL should be initiated with a 5 mg dose and titrated slowly upward.
Cyclobenzaprine is used short-term to treat muscle spasms.
Animal studies indicate that cyclobenzaprine does not act at the neuromuscular junction or directly on skeletal muscle.
It can cause changes in blood pressure, body temperature and lead to a change in behavior.

Call your doctor or local poison control center immediately if you have an allergic reaction. Call 911 or go to the nearest emergency room if your symptoms are severe. Do not take this drug again if you’ve ever had an allergic reaction to it. Abuse of cyclobenzaprine is relatively rare but most often occurs in the context of other substance use.

Flexeril Can Be Abused but the High Isn’t Worth the Risk

Ask your pharmacist any questions you have about refilling your prescription. RxList does not provide medical advice, diagnosis or treatment. Secondary endpoints included a physician’s evaluation of the presence and extent of palpable muscle spasm. In light of these findings, therapy with FLEXERIL in the elderly should be initiated with a 5 mg dose and titrated slowly upward. Safety and effectiveness of FLEXERIL in pediatric patients below 15 years of age have not been established.

Multiple drug ingestion (including alcohol) is common in deliberate cyclobenzaprine overdose. As management of overdose is complex and changing, it is recommended that the physician contact a poison control center for current information on treatment. Signs and symptoms of toxicity may develop rapidly after cyclobenzaprine overdose; therefore, hospital monitoring is required as soon as possible. The acute oral LD50 of FLEXERIL is approximately 338 and 425 mg/kg in mice and rats, respectively.

It can occur when Tetracyclic Compounds and MAOIs both raise the level of serotonin too high in the body. It can cause changes in blood pressure, body temperature and lead to a change in behavior. To add to the risk of overdose, addiction, and mixing substances along with cyclobenzaprine recreational use, patients can also be extremely allergic to Flexeril which can cause the body to react quickly. If a person has an overactive thyroid, heart issues or problems with the liver, Flexeril can be risky and should not be taken. I had been prescribed this drug for back pain and to help with muscle spasms. It is a very powerful muscle relaxer, and it works quite well.

Based on this high degree of structural homology to known sedating histamine H1 receptor antagonists, we hypothesized that the sedative and somnolence effects of cyclobenzaprine are mediated by off-target antagonism of central H1R. This medicine will add to the effects of alcohol and other CNS depressants can i take flexeril with aleve (medicines that slow down the nervous system, possibly causing drowsiness). Check with your doctor before taking any of the above while you are using this medicine. Cyclobenzaprine (Flexeril) is structurally similar to TCAs and, as such, demonstrates significant anticholinergic side effects.
