Another potential side effect of Flexeril abuse is cyclobenzaprine overdose, especially if taken in conjunction with other substances such as other CNS depressants like alcohol. Flexeril causes the body to become relaxed and abusing the substance in high doses can lead to cardiac arrest, low blood pressure, heart attack, and seizures.

A Flexeril high is really only possible when the medication is abused or when the patient first takes it. Some users, however, have If someone takes more than the prescription suggests, the Flexeril high can include an altered state of mind.

The efficacy of FLEXERIL 5 mg was demonstrated in two seven-day, double-blind, controlled clinical trials enrolling 1405 patients. One study compared FLEXERIL 5 mg and 10 mg t.i.d. to placebo; and a second study compared FLEXERIL 5 mg and 2.5 mg t.i.d. to placebo. Primary endpoints for both trials were determined by patient-generated data and included global impression of change, medication helpfulness, and relief from starting backache. Each endpoint consisted of a score on a 5-point rating scale (from 0 or worst outcome to 4 or best outcome). The plasma concentration of cyclobenzaprine is increased in the elderly (see CLINICAL PHARMACOLOGY, Pharmacokinetics, Elderly). The elderly may also be more at risk for CNS adverse events such as hallucinations and confusion, cardiac events resulting in falls or other sequelae, drug-drug and drug-disease interactions.

I started to get tired, but I fought that feeling off. About three hours in, I started having some visual hallucinations. I thought I saw someone standing in my bedroom, and it looked like a child. I kept seeing bright flashes of light that were gone before I could even register that I had seen them. At that point, I needed it, and I slept for seven hours straight.

Based on individual patient response, the dose may be increased to 10 mg three times a day. Use of FLEXERIL for periods longer than two or three weeks is not recommended. Eight double-blind controlled clinical studies were performed in 642 patients comparing FLEXERIL 10 mg, diazepam, and placebo. Muscle spasm, local pain and tenderness, limitation of motion, and restriction in activities of daily living were evaluated. In three of these studies there was a significantly greater improvement with FLEXERIL than with diazepam, while in the other studies the improvement following both treatments was comparable. In patients with CNS depression, early intubation is advised because of the potential for abrupt deterioration.
