How long does Diazepam take to work for anxiety

Diazepam is an effective medicine to calm various levels of anxiety, fits and muscle spasms. In most patients, the medicine usually takes 1 or 1.5 hours to show its peak effects.  Since Diazepam metabolizes by triggering metabolites, it may take up to 24 hours to wear off from your body. In some patients, the duration of wearing Diazepam may be longer than 24 hours. 

The speed of Diazepam showing its impact may vary depending on many variables. The effect may also vary for different symptoms you are taking it for. 

  • For anxiety, Diazepam should exhibit its effect within a few hours, and the symptoms should be fully treated within two weeks. 
  • If you are taking Diazepam for fits or seizures in the rectal tube, the symptoms should improve after 10 minutes. 
  • In case of muscle spasms, symptoms may improve within 15 minutes. However, complete relaxation of muscles will occur if you take Diazepam regularly for a few weeks. 

However, there are conditions where Diazepam's effects may differ for several reasons.
