DRUG INTERACTIONS: Methocarbamol can increase sedation if taken with narcotic painkillers, alcohol, sedative or hypnotic medications, and other medications that depress the central nervous system. Loss of consciousness, troubled breathing, lowered heart rate, and in severe cases death or coma can also occur.

PREGNANCY: There are no adequate studies of methocarbamol to determine safe and effective use in pregnant women. Methocarbamol should be avoided in pregnant mothers to avoid any risk to the unborn.
