Hello,
Clobetasol is a highly potent steroid and should be sued with caution on the delicate skin of penis. Penile psoriasis can be treated but it commonly has recurrences also. So a regular treatment is required for this.Treatment options include Ointment and creams containing coal tar, dithranol (anthralin), corticosteroids like desoximetasone (Topicort), vitamin D3 analogues (for example, calcipotriol), and retinoids,Psoralen+UVA and PUVB therapy. Over time, psoriasis can become resistant to a specific therapy. Treatments may be periodically changed to prevent resistance developing (tachyphylaxis) and to reduce the chance of adverse reactions occurring.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Steroid absorbtion of potent steroids like clobetasol, especially through penile skin could lead to severe cutaneous atrophy. Follow your doc prescriptions only.
