Can my drugs (allopurinol, quetiapine, concerta) can cause a vague vision of an eye or is it arciform deficit?

Good morning, sir. It is certain that the situation you describe requires a medical consultation! Before looking into the possible connection between your vision problem and your medications, we must make sure that you receive a proper diagnosis. This means that you need to see a doctor as soon as possible. Once the diagnosis is made, talk to a pharmacist (or come back to me) so that we can examine if one (or more) of your medications could be the cause.
