Hi Sir Thanks for seeking help here. Well when you have mentioned about forgetting things after medication....it means the impairment in working memory .....is the cause of this .... First we need to manage all the active symptoms. Age of 29 I don't think....you should have a new onset memory issues ..... Anyway let's have a clear discussion for better understanding about your illness. Coming to the mechanism of these medications....they are antipsychotic which improves both positive and negative symptoms..... Action on dopamine and serotonin receptors.
