Venlafaxine vomiting after first dose?

I am feeling nauseous after taking venoflaxine 75 mil for anxiety. I also get anxious about feeling nauseous and as pure O health anxiety is part of my problem I usually start wondering whether I have stomach or bowel cancer. But I did a few things wrong which made my problem worse. The first was that I stitched from paroxetine too fast and didn’t take enough time to come off one before starting the other. Another was that I often took the tablet without food and then much later on would eat a rich cake or something of the sort. I think I was probably asking for trouble.

I've been on venlafaxine now for a few months and they still really make me ill. About 45mins after taking them I get an intense nauseous feeling that doesn't go away for hours. I try to take them on a full stomach but struggle to eat because I feel so nauseous all the time. If I miss a dose I feel sick as well. I've been told to stick with them as its just my body getting used to them but I'm on my own with a baby to look after, so being unwell isn't really an option for me. I tried to stop taking them but my mental health suffered severely so had to start taking them again. Somebody please tell me that I will get used to them as its really starting to affect me
Feeling ill almost constantly.

Hi Effy,

I've been on Effexor for about two months now and experienced severe nausea and vomiting for the first two days of being on it. Now again, two months in, I'm incredibly nauseous constantly and vomiting the same way you describe. Going to see my doctor to get off of this ASAP. Cannot deal with the side effects either. The additional heightened anxiety, dizziness, blurred vision, profuse sweating, etc. are all extremely interrupting to my daily life and work schedule. You aren't/weren't alone in your experience!

I was put on 35mg when I first started taking venlafaxine, I took them for about 2 weeks and had little to no problem although I did have blurred vision, nausea and shakes but that past after a couple days, when that ran out I went on 75mg but I waited too long to get the prescription, about a month, so when I took it I was fine but really tired, a few hours later the nausea started and I ended up vomiting all night ( I took the pill around 10:30am that day, and didn't feel sick til around 5pm) it's now the next day and I'm still vomiting.

Well eff SWAN; HAS given you a good answer and same with me very few people complain about vomiting. I think along with your problem your worrying too much make sure you have something in the stomach as you did and maybe ask the doctor tomorrow about something for vomiting. It is very possible that these side effects may be gone in less than a week or up to 2 weeks but many get lucky and are able to have the side effects stop sooner. I would keep trying if you can this has been very effective for many just have to convince yourself to get through the worse part here. Try and use the head for some Positivity. Good luck to you.

Hi, Effy! About 37% of Effexor users experience nausea during the first few days to a couple weeks of initiating therapy and about 6% experience actual vomiting.
The good news is that these side effects generally resolve rather quickly and they also generally respond very well to OTC preparations such as Pepto Bismol. meclizine, and Dramamine. Dramamine can make some folks sleepy so it would be best to take this in the evening.
I can sympathize with your aversion to vomiting as I feel the same way. I break out in a cold sweat just thinking about it.
Hopeful you'll get through this rough start quickly as Effexor/venlafaxine is an excellent medication for both depression and anxiety. I took it for over four years with excellent results.
Best regards and good luck!

200 of sertraline to 75 Effexor is a big jump. Did your doctor wean you off the sertraline or just switch you? If it was a sudden switch that could definitely cause the vomiting. If you were weaned but are still experiencing the vomiting I would guess that your body is just adjusting to the switch, especially if you were on the sertraline for an extended period of time. I haven't heard a lot of people experiencing nausea or vomiting with Effexor so I would say stick it out for a couple weeks if you can. You can obviously talk to your doctor tomorrow but usually the initial side effects will subside within a few weeks.
