Aluminum antiperspirant commonly causes itching and burning at sites where it is applied. There are a number of ways to help lessen the severity of these effects, including applying the antiperspirant less frequently, avoiding applying to recently shaved areas, and avoiding applying to areas with broken skin. You can also try applying over-the-counter hydrocortisone cream to help relieve the symptoms. And, you can always reach out to your doctor at any time to report side effects and discuss potentially changing or stopping your treatment plan.
