How long can I use Clobex spray for alopecia areata?

I recommend following up with the prescribing Doctor about usage and duration recommendations. Prp/progesterone and/or hair transplantation are great non-invasive options. See an expert. Best, Dr. Emer

You'll simply want to give your dermatologist's office a call and figure out how long they want you to use it for. It's important you know exactly how to use these medications.  Generally speaking provided there are periods of time that a patient takes a break from these mediations, the use can be many weeks. For example, the spray may be used daily for 5 weeks followed by a 3 weeks break or the spray is used 5 days per week with the weekends off. 
Clobex spray does not work for everyone with AA. Speak to your dermatologist about how they want you to use the medication and when your next follow up appointment is. If a response is not present after 8-10 weeks, steroid injections or other treatments may be considered. 

YOU SHOULD BE ASKING THAT QUESTION TO THE DOCTOR WHO IS PRESCRIBING THE CLOBEX FOR YOU. AS LONG TERM USE OF CLOBEX HAS CONSEQUENCES
