Can we take the 10mg muscle relaxant at 8pm and take the 1mg Pro lorazepam at 8:30pm?

Yes, you can take the muscle relaxant 10mg and the lorazepam 1mg at the specified times. However, because both medications can cause drowsiness, it may be a good idea to consider taking a lower dose of one or both of them to avoid excessive sleepiness. If you have any other questions or concerns, feel free to ask a pharmacist for advice.
