Hello and welcome, Diazepam belongs to benzodiazepines which increases the effect of the neurotransmitter (GABA) that moderates the activity of nerve signals in the brain. You should carefully follow your doctor’s instructions while taking the medicine. You should seek emergency care when you overdose and/or you have any of the following symptoms: -confusion, extreme drowsiness, fainting, slurred speech -walking difficulty, loss of balance, dizziness -difficulty breathing Diazepam interacts with many other medicines, therefore before starting any new medicine (even supplements) always contact your doctor about drug interactions. Furthermore, you should not stop diazepam suddenly (may causes withdrawal symptoms) and never drink alcohol while on diazepam. I hope I have answered your question. Please, feel free to ask me more in HCM if there is anything else you need to know. Thank you, Malik Amonov MD
