Methocarbamol
Skeletal muscle relaxant
Brand names: Robaxin
Oral health effects
Xerostomia (dry mouth)
Mild dry mouth and sedation; sometimes used for muscular orofacial pain.
Clinical management: Hydration, salivary substitutes, high-fluoride caries prevention.
Metallic taste (dysgeusia)
The label lists metallic taste among adverse reactions.
Clinical management: Ask about altered or metallic taste, which can reduce appetite and oral comfort; reassure that it is drug-related and often fades. Rule out oral candidiasis or poor hygiene as contributors and encourage sugar-free options rather than sweet foods/drinks used to mask the taste.
