How long will it take for my medications to help get rid of my delusions? Will they ever go away?

I need to clarify that I my doctorate is in clinical psychology, not medicine / psychiatry, so I can give you my opinion based on experience, but I recommend you discuss medication concerns with your prescriber. Following is what I do know based on my experience and training:

Antipsychotic medications (which, based on your question I assume you are taking) have varying degrees of effectiveness based on many different factors.

Unfortunately, finding the right medication (or combination of medications) and the right dose is not an exact science. There is often a lot of trial and error involved, which can be very frustrating for the patient. While a particular dose of one medication may completely alleviate symptoms for one person, that same medication may not work for another person, or may not work as well, or may work better at a much higher dose.

Your prescriber may start you on a low dose and gradually increase it, depending on your tolerance to the medicatio, side effects you experience, and how well it is impacting your symptoms. If you have been on your medication for several weeks and are still experiencing your delusions, it may be time to consider a higher dose or a different medication. However, you do need to give medications a chance to work effectively.

There is no guarantee that your symptoms will subside 100% even with medication. But antipsychotics have proven to be very effective for many individuals with schizophrenia, allowing them to live productive lives while helping keep symptoms under control.
