Hi,
You said your daughter suffers from acne cystica..a type of acne.. She has taken long term treatment with improvement...but got reaction to antibiotics,so stopped.... Acne is a multifactorial disease. There may be different form of acne like comedones,papules,pustules or cystic lesions. It is a relapsing condition. Sometime cysts might get infected.
Stress, anxiety,
sleeplessness,drugs like steroids,oil food,dandruff..etc might exacerbate the disease.
She has to take treatment for long time to have good response...under observation of dermatologist.
You
consult dermatologist...have perfect treatment. If there is reaction,he might replace the drug.
He might give antibiotic like
minocycline 50 mg daily in morning and
isotretinoin cap in low dose of 5 mg daily at night .
And he might advise to apply clindamycine gel in morning and
adapalene gel at night. And to cleanse the face with antiseptic like acmed face wash. If there is a need,he might give intralesional steroid injection in a cyst.
Have pateince for the result. It may take few months for the good result. I hope you got my answer.
Thanks..
Dr. Ilyas Patel MD
