With a transdermal patch, the active ingredient bypasses your digestive system and your bloodstream absorbs it. Transdermal patch side effects and functions include:

• Controlled delivery over a prolonged amount of time
• Reduced peaks and troughs in blood-drug amounts
• Easier to use
• Targeted use – patches can be placed on or near affected sites instead of a medication traveling through the entire body
• If you have a negative reaction, removing the patch can reduce symptoms more quickly than waiting for your body to process an oral supplement
• Painless and convenient
• Great for people who have a difficult time swallowing pills
