I accidentally took 2x venlafaxine at night

@mathiask Welcome to Mayo Clinic Connect. I’m sorry it took awhile to get an answer for you. I hope this one from a poison center will help.

Taking lots of pills and changing doses is always complicated and ripe for errors. I know how hard it is! I went from 1 pill per day before my autoimmune disease to almost 20! I try to set up the pills for a week at a time and always do it when I’m not distracted. I use a weekly pill container that has spaces for morning and evening doses for 7 days. If you don’t have a safe and careful plan for your medications, please set one up!
Basically, what i read was that 1 extra pill isn’t dangerous, but that you should check with your doctor.
What has your doctor said?

Bonjour habituellement le matin je prend 150mg + 37.5mg mais c est la premiere ca m arrive ce soir j ai voulu prendre tylenol mais j ai repris 150mg d effexor est ce dangereux ????

Bonjour @domi1234 I am going to respond in English because my written French grammar is not good. I hope that will be OK for you. If not, please tell me and I will respond in French.

We are not physicians or medical providers on Mayo Clinic Connect so I cannot advise you on your question about Effexor + Tylenol. This is a question to ask your physician who prescribed Effexor.

@domi1234, bienvenue. I agree with @naturegirl5. Please contact your doctor about taking an extra dose of your medication accidentally.

Here is an article that will likely put your mind at ease.
