Hello,
Based on the history provided, you have been taking Pentasa (
mesalazine) as a treatment for Crohn's disease. In my opinion you should have a physical examination by a
dermatologist for the acne that you have, to diagnose if this is
cystic acne, a skin complication of Crohn's disease ,or a side effect of Mesalazine. Cystic acne is a rare skin disease, that occurs commonly in 11-30 years old patients and is caused by
hormonal changes.
Acne is a very uncommon side effect of Mesalazine.
Choosing the right treatment is important because it's different for each of these conditions:
-You have to avoid taking Mesalazine if it's caused by it.
-You have to use
Isotretinoin if this is a cystic acne.
Hope I have answered your query.
Let me know if I can assist you further.
Regards,
Dr. Suela Gjata,
