Methocarbamol is a generic medication used in treating opiate withdrawal, explains Drugs.com. Opiate withdrawal is an acute condition initiated by the abrupt end or reduction of the extended use of opiates and results in symptoms such as vomiting, sweating, diarrhea, drug cravings and depression. As a muscle relaxant, Methocarbamol inhibits the patient's nerve signals.
Opiate withdrawal occurs because prolonged exposure to opiates changes the functioning of certain parts of the nervous system, notes Healthline. Eventually, affected nerve endings require continued exposure to the opiate for normal operation. Prolonged exposure also leads to desensitization, making increasingly higher doses of the drug necessary to achieve the same effect. Areas potentially affected by opiates include the limbic system, the spinal cord and the brain stem. Many individuals remain unaware of their dependence and may not realize they are experiencing opiate withdrawal, believing the symptoms to be caused by another condition.
Methocarbamol may cause allergic reactions and reduce cognitive performance, cautions Drugs.com. Individuals taking methocarbamol should be particularly careful while performing tasks that require sustained attention, such as driving. Serious side effects include seizures, jaundice, heart rate reductions and flu-like symptoms. Other side effects include blurred vision, flushed skin, headache, dizziness, nausea and insomnia. Alcohol consumption may worsen some side effects.
