Hello, Welcome to Just Answer and thanks for your question. Overexposure to fumes can cause anything from irritation to chemical pneumonia. For just irritation there is no pill. One should ventilate the painted area, and get as much fresh air as possible. The person's body takes care of the problem. If chemical pneumonia occurs, sputum can be cultured and the proper medication given by tablet if some bacteria grow. Otherwise, fresh air, and perhaps a breathing treatment if the person is having trouble breathing would be the prescription.
It takes a lot of overexposure to cause any side effects lasting more than 24 hours. If the side effects are actually related to overexposure, then it is the side effects that are treated. For example if the person has chemical pneumonia, the pneumonia is treated. Vertigo, loss of awareness, blurred vision, loss of concentration aren't common symptoms even from prolonged exposure at very high concentrations. There is no way to tell what is causing the symptoms without an examination by a health care provider.
I would suggest you consult your doctor for an examination to determine exactly what is causing your symptoms. A one-time exposure to paint fumes won't cause depression. I am assuming that by "sytems" you actually mean symptoms. You can't get a diagnosis by "researching" stuff for yourself online, and no one can give you a diagnosis online. That is impossible. You have to actually see a medical professional in person for an examination. Your disrespect is noted and excused, since you have no way of knowing these facts.
