I had the Flu days ago and treated it with Tamiflu. At the same time, Me, my friend, and her mother all came down with pityriasis rosea. Her and her mother s rash is widespread and has progressed a lot in ten days, while on the other hand i have had no more than six spots on my entire body, (four on my left arm, in different spots on my arm. The other two are on my chin). Could the Tamiflu be stunting the progression of the Pityriasis Rosea? I ve heard other antivirals show some signs of successful treatment, but haven t heard of any cases with Tamiflu involved.
