Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)

• Have patient report immediately to prescriber severe application site irritation or ingrown toenail (HCAHPS).

Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
