Medication Summary
The use of topical and systemic steroids, vasodilators, intravenous calcium followed by intramuscular vitamin K, and ultraviolet B radiation has been anecdotally reported in the literature. In most cases of pernio, the value of these agents is questionable and often disputed.
Calcium channel blockers
Class Summary
Peripheral arterial vasodilators may be effective in the treatment and prevention of pernio.[7, 12, 13]
Nifedipine (Procardia)
Relaxes coronary smooth muscle and produces coronary vasodilation, which in turn improves myocardial oxygen delivery. Small studies have shown this drug to be effective in reducing symptoms associated with severe recurrent pernio. Currently is considered DOC.
