I have seen lots of patients recovering from anxiety and depression once the medications kick in. There is a huge initial push in their treatment, which makes the patient understand themselves, their problem, accept the problem and agrees for further interventions. Medications without a doubt, play a very crucial role for almost all kinds of mental health disorders and once needs a certain levels of drug in blood stream for it to work efficiently. Hence, underdosage or overdosage may affect outcome plus regularity also matters.
