Hi, thanks for updating. It's a bit disappointing you haven't noticed any major improvements although your dermatologist is correct that it can take a few months for the drug to build up in your system.
My question is what has your dermatologist suggested for a plan B? I think your dermatologist is good considering he was willing to trial a medication like what you are on, I can understand his reasoning for wanting to trial it so im very curious to see what his next move will be in treating your lips.
May I ask what country do you live in?
Hope you are doing well! Look forward to your response!
