Hi I am a 30 years old male taking prescribed medicines for anxiety, depression and stress. I am being prescribed tablets such as lithosun sr, qutipin 100 mg, ativan 2 mg, dicorate er 500 mg almost for past 2 yrs. What is suggested duration for taking these medicines cause it might harm. Already I am feeling the side effects such as headache, blurred vision etc. Also is this dose a less dose or a high dose.
