Some Drugs May Worsen Rosacea
Certain medications themselves can trigger or aggravate rosacea signs and symptoms, according to Dr. John Wolf, chairman of dermatology at Baylor College of Medicine.
"Rosacea can worsen for some patients from taking vasodilator drugs because of their ability to dilate the blood vessels," he said. "Beta blockers and niacin (vitamin B3) may also cause blood to rush to the face, resulting in a rosacea flare-up."
