Which antipsychotic medicine will cause the least weight gain?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hi doctor,

Which atypical antipsychotic will cause the least weight gain? Abilify is not an option as I am allergic to it. Also, Geodon or Zeldox gave me severe drowsiness to the point that I had to sleep or could not open my eyes. Please help me.

Hi,

Welcome to icliniq.com.

Haloperidol is an antipsychotic with the least weight gain potential. If you are maintaining well on the antipsychotic which you are prescribed now, I advise you to continue taking it as discontinuation can precipitate a relapse. The medicines are prescribed based on the risk-benefit ratio. Hence, if there are no major adverse effects, then I advise you to continue your prescribed medications. Thank you.
