==Side effects==
Patients most commonly report [[sedation]] as the main adverse effect of muscle relaxants. Usually, people become less alert when they are under the effects of these drugs. People are normally advised not to drive [[vehicles]] or operate [[heavy machinery]] while under muscle relaxants' effects.

Cyclobenzaprine produces confusion and [[lethargy]], as well as [[anticholinergic]] side effects. When taken in excess or in combination with other substances, it may also be [[toxic]]. While the body adjusts to this medication, it is possible for patients to experience [[dry mouth]], [[fatigue (medical)|fatigue]], lightheadedness, [[constipation]] or [[blurred vision]]. Some serious but unlikely side effects may be experienced, including mental or mood changes, possible confusion and [[hallucinations]], and difficulty urinating. In a very few cases, very serious but rare side effects may be experienced: irregular heartbeat, yellowing of eyes or skin, [[fainting]], [[abdominal pain]] including [[stomach ache]], [[nausea]] or [[vomiting]], [[lack of appetite]], seizures, dark urine or loss of coordination.<ref>{{cite web |url=http://www.medicinenet.com/cyclobenzaprine-oral/article.htm |title=Cyclobenzaprine-Oral |access-date=2010-07-09}}</ref>

Patients taking carisoprodol for a prolonged time have reported [[Substance dependence|dependence]], [[Drug withdrawal|withdrawal]] and abuse, although most of these cases were reported by patients with addiction history. These effects were also reported by patients who took it in combination with other drugs with abuse potential, and in fewer cases, reports of carisoprodol-associated abuse appeared when used without other drugs with abuse potential.<ref>{{cite web |url=https://www.drugs.com/pro/carisoprodol.html |title=Carisoprodolx |access-date=2010-07-09}}</ref>
