Yes, whenever taking a medicine that affects your hormones and emotions, I would say better be safe than sorry and leave the alcohol aside. Another thing is that alcohol can usually lead to depression, it's one of those stimulants that ends up making people feel down, so even if it's not interfering directly, it might be erasing the effects of the drug and perpetuating the issue. So, even if you weren't taking the medicine, I would probably also advice about minimizing your exposure to alcohol, specially if you're prone to anxiety and poor sleep.You are probably right.
I have the oral drops version of alimemazin evolan. I read the medication package insert a while back. It said you can't mix it with alcohol or milk while dosing it. But you could mix it with water or juice etc. then drink it. That's what it said regarding alcohol if I remember correctly. I used the last prescribed bottle some weeks ago, I have to call to get a new one approved. I am not forced to take it but I can decide to take it when needed (1 ml, 3 times a day). I use it against unease and for better sleep. If it helps or not I can't say for sure.
Was that the reason you were prescribed the Alimemazin? were you diagnosed with anything in particular? just curious.
