Robaxin - Comprehensive Usage Guide: instructions, indications, composition, side effects

• Active Ingredient: Methocarbamol
• Excipients: May include corn starch, magnesium stearate, povidone, and other inactive ingredients depending on the formulation.

• Tablets: Available in various strengths, including 500 mg and 750 mg tablets.
• Injectable Solution: Available for intravenous or intramuscular administration.

Robaxin belongs to the pharmacological group of skeletal muscle relaxants (ATC code: M03BA03).

• Pharmacodynamics: Methocarbamol acts as a centrally acting muscle relaxant by inhibiting the transmission of impulses in the spinal cord, resulting in skeletal muscle relaxation and relief from muscle spasm.
• Pharmacokinetics: Following oral administration, methocarbamol is rapidly absorbed from the gastrointestinal tract, with peak plasma concentrations achieved within 1 to 2 hours. It undergoes metabolism in the liver and is excreted primarily in the urine.

Robaxin is indicated for the relief of discomfort associated with acute, painful musculoskeletal conditions, such as muscle spasm, sprains, strains, and back pain.

Robaxin is contraindicated in individuals with:

• Hypersensitivity to methocarbamol or any component of the formulation.
• Renal impairment or failure.
• History of myasthenia gravis.

Methocarbamol may interact with other medications, including:

• Central nervous system depressants, such as alcohol, benzodiazepines, and opioids, leading to additive sedative effects.
• Drugs with anticholinergic properties, potentially increasing the risk of side effects.

• Robaxin tablets should be taken orally with or without food, usually four times daily, as directed by a healthcare provider.
• The dosage and duration of therapy depend on the severity of the musculoskeletal condition and individual patient response.
• Treatment should be initiated at a low dose and titrated gradually to achieve optimal pain relief.

• Robaxin should be used with caution during pregnancy, especially during the first trimester, and only if the potential benefits outweigh the risks.
• It may be excreted in breast milk, so breastfeeding is not recommended during treatment with Robaxin.

• Dosage adjustments may be necessary in patients with renal impairment to avoid drug accumulation and potential toxicity.
• Injectable Robaxin should be administered by healthcare professionals experienced in intravenous or intramuscular injection techniques.

In case of overdose, supportive measures should be initiated, and medical attention should be sought immediately. Symptoms of overdose may include drowsiness, respiratory depression, hypotension, and coma.

Common side effects of Robaxin may include:

• Drowsiness
• Dizziness
• Fatigue
• Nausea
• Headache

Robaxin tablets should be stored at controlled room temperature (20-25°C) in a dry place, protected from light and moisture. The expiration date should be checked before use.
