Methocarbamol should be used with caution in patients with impaired renal and/or hepatic function.
Patients should beadvised that the intake of alcohol during the treatment with methocarbamol or a combination with other centrally acting agents can lead to an increase in effects.
Patients with rare hereditary problems of galactose intolerance, total lactase deficiency or glucose-galactose malabsorption should not take this medicinal product.
Patients who are allergic to peanut or soya, should not take this medicinal product.
Methocarbamol may cause colour interference in screening tests for hydroxyindolacetic acid (5-HIAA) and vanillylmandelic acid (VMA).
The concomitant administration of methocarbamol and centrally acting medicinal products such as barbiturates, opioids and appetite suppressants may mutually potentiate the effects of the medicinal products.
Methocarbamol can potentiate the effect of anticholinergic medicinal products such as atropine and some psychotropic medicinal products.
Using methocarbamol together with alcohol may potentiate the effect of the medicinal product.
Methocarbamol may inhibit the effect of pyridostigmine bromide. Therefore methocarbamol must not be administered to patients with myasthenia gravis receiving pyridostigmine.
There is no experience in the use of methocarbamol during pregnancy. Animal studies have not established safe use of methocarbamol with regard to effects upon pregnancy, embryonic/foetal development, parturition and postnatal development (see section 5.3). The potential risk for humans is not known. Therefore, methocarbamol should not be used during pregnancy.
It is not known whether methocarbamol and/or its metabolites pass into human milk. Methocarbamol and/or its metabolites are excreted into the milk of lactating dogs. Therefore methocarbamol should not be used by breast-feeding women.
Animal reproductive studies have not been conducted with methocarbamol.
Methocarbamol has moderate influence on the ability to drive and use machines as methocarbamol may cause dizziness or drowsiness, especially if other medications capable of causing drowsiness are also being taken. Possible undesirable effects of methocarbamol may affect the patient’s ability to drive and use machines.
