Is it ok to mix Valium and tizanidine?

It is not advisable to mix Valium (diazepam) and tizanidine, as they both act on the central nervous system and can potentiate each other's effects. This could lead to an increased risk of side effects such as drowsiness, dizziness, impaired coordination, and respiratory depression. It is always important to consult a doctor or pharmacist before taking any medications together.
