PRP can be difficult to treat and many treatment options have been tried. There is little information on which treatments are best because none have been studied in large clinical trials. Treatment options may vary based on the symptoms in each person but often involve a combination of medicines taken internally and applied topically to the skin.
Topical therapy options may include corticosteroids, keratolytics, calcipotriol, tretinoin, and tazarotene. For people with mild PRP, using one or more of these may be enough to control symptoms.
Many of these treatments have shown results in only a few patients, and some can have serious side effects. The risks and benefits of each treatment option should be discussed with your doctor.

Is vitamin A intake known to worsen the symptoms of pityriasis rubra pilaris?
We are not aware of any published reports that eating foods high in vitamin A worsens the symptoms of pityriasis rubra pilaris (PRP). On the contrary, vitamin A, as well as synthetic vitamin A derivatives, are sometimes used to treat this condition and attempt to improve the symptoms of PRP. However, response to these treatments varies among affected people.
Abnormal vitamin A metabolism was once proposed as a possible factor contributing to the development of PRP. Early theories proposed that vitamin A deficiency might play a role in causing the condition. However, further studies did not confirm these theories. Whether abnormal vitamin A metabolism is associated with PRP remains unclear.
