It really depends on the treatment your practitioner prescribes you.
Some treatment options take 15 minutes, others 2 hours, with the effects lasting between 4 & 36 hours. It's also common for patients to see increased efficacy as they become more comfortable with the medication and confident in its effects.
For more detailed information on getting the best out of your medication, please read through your practitioner's letter or the Help section on your patient profile.
If you are concerned regarding the progress of your treatment or you have further questions, please message our Medical Support Team here for additional support.
