What is the link between trouble swallowing and Seroquel?

Any Neuroleptics may cause dysphagia, however tighter D2 binding agents such as Haldol, Prolixin etc are more likely. Even Seroquel/Zyprexa may cause it. In this case:
I would decrease the dose, if psych Sx allow, try to stay away from Dopamine blockade, try anti-cholenergics at low dose (which can also cause dysphagia), or try partial agonists such as Abilify or Rexulti. Prolonged use of anticholinergics should be avoided and Neuroleptics should be used at smallest dose possible.

I have been on this for 3 years. I started having severe Dysphagia (trouble swallowing )recently within an hour of taking. I take to help me sleep. I have depression and anxiety with severe insomnia since death of son. I am weaning off after reading others have this. Sometimes I get dizziness /weakness too. I had a severe choking incident the other night. Calling dr and going off.

You need to find another medication. I have permanent dysphagia and was on Seroquel for about two years.

Difficulty in swallowing is a reported side-effect of Seroquel - epecially when first starting treatment. It may subside with time.

You should see your doctor if this is happening .
