I take Desvenlafaxine 100mg. everyday. I have ran out before its time to see my dr. BUT I need something to take to help me for the next 4 days. Is there another drug that I could take to help me until I see my dr? I am feeling the loss of this durg & need something until then. I DON T have $2.00 for an answer let alone $15.00. Can you help me at least this one time?
