Other medicines and Somazina
Inform your doctor or pharmacist if you are taking or have recently taken any other medicines, including those obtained without a prescription.
Somazina potentiates the effects of L-Dopa; therefore, it should not be administered concomitantly with medicines containing L-Dopa without consulting your doctor. Medicines containing L-Dopa are commonly used to treat Parkinson's disease.
Somazina should not be administered together with medicines containing meclofenoxate, a cerebral stimulant.
