It is highly recommended. In some cases, there are people who do not have recurring episodes, but when there is psychosis involved, there is a very high chance of those symptoms coming back when unmedicated....so in your case, it would be risky to not take medication. I have met some people who get so sick from medication and have medical conditions where pdocs decide it is best to go without it until absolutely needed, but if that isn't the case, then I think it's best to consider that the benefits of taking meds outweigh all the disadvantages. You want to keep yourself safe and well, most importantly. Best of luck.... ((HUGS))
