Q: Are there common skin reactions associated with Persantin?
Official regulatory labeling indicates that rash and hives (urticaria) are reported signs of a hypersensitivity reaction. Other skin-related effects, such as purple-colored spots or patches on the skin, have also been reported in patient populations.
Q: Can Persantin be taken with common pain relievers like ibuprofen?
