Stacy Wiegman, PharmD, Pharmacy, answeredYou should not use Preparation H if you have had an allergic reaction to it in the past or are allergic to any of its ingredients. Children should not use it unless directed to do so by a doctor. If you have diabetes, heart disease, thyroid problems, high blood pressure, or an enlarged prostate, check with your doctor to see if it is safe for you to use Preparation H and to ask about negative interactions with any medications. If you use this medication for a week and have not seen any improvement, you may need to see your doctor.
