Mirtazapine Side effect or allergic reaction? Help

I started taking mirtazipine last friday, the first 2 days i was knocked out and slept for about 11 hours each night, which was annoying despite not sleeping well for a while as i had no energy. I ate a lot due to increased appetite which is normal but now i can wake up with more energy whilst getting a good nights sleep and i am now tracking pre-prepared food so i dont over indulge.

However I have woke up this morning and my face is completely puffy and looks somewhat swollen, I’m not sure if this is a side effect which will go over a few days or if it’s some sort of reaction? please can someone settle my mind or suggest anything that may help

You might like to read the leaflet which should be in the Mirtazapine carton. Your problem may not be one of the symptoms indicated as serious, but if you feel it could be, it would be reasonable to contact your doctor. I would not dare express an opinion myself. If you don’t have the leaflet, it will be on the Internet.
