How Long Does Zanaflex Stay In The Blood Stream?
How long does zanaflex stay in your blood? I was given a perscription from the E.R. 2 months ago for 15 due to back spasms. I took the 3 a day for the first 3 days but not the rest because I did not need them. However the last 2 days I had more spasms so I took 3 Saturday and 3 Sunday. How long will they stay in my blood? i have to give blood work Thursday. Will it be gone?

Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
The plasma half-life of the drug Zanaflex is 2.5 hours, so it does not show up in the system anymore beyond 24 hours.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Purva Patel
