OTC Oxybutynin Patch Dosage

Everyone uses the same dosage for OTC oxybutynin patches, regardless of age or weight. When treating an overactive bladder in women, place one patch on the skin of the abdomen, hips, or buttocks every four days. Don't forget to take off the old patch before you apply a new one. Also, make sure to rotate application sites.

An Introduction to Your Dosage of OTC Oxybutynin Patch

There is only one standard recommended dose of OTC oxybutynin patch (Oxytrol® For Women), regardless of your age or weight. As is always the case, do not adjust your dosage unless your healthcare provider specifically tells you to do so.

Recommended OTC Oxybutynin Patch Dosing Guidelines

The recommended dose of OTC oxybutynin patch for treating an overactive bladder is one patch applied every four days. Every patch delivers 3.9 mg of oxybutynin (the active ingredient) each day for four days. After four days of use, remove the patch and apply a new one.
Having trouble remembering when to apply your patch? Keep in mind that the prescription version (Oxytrol®) which comes in the exact same strength, is approved to be applied twice a week (every three or four days), making it easier to remember. Just pick two days (for instance, Sunday and Wednesday) and change your patch on those days every week. OTC oxybutynin patch is not officially approved for this type of dosing schedule, but because the two products come in the same strength, there probably isn't any harm using the twice-a-week dosing schedule.

General Information on Using OTC Oxybutynin Patch

Some considerations to keep in mind during treatment with OTC oxybutynin patch include the following:
  • This product comes in patch form. It is applied to the skin of the abdomen (stomach), hips, or buttocks; do not put it on skin that is regularly exposed to sunlight.
  • Each patch is worn for four days.
  • Make sure to take the old patch off when you apply a new one.
  • Choose a clean, dry area of the skin that is not irritated or damaged. Rotate the application sites so you don't use the same application site two times in a row.
  • You should be able to shower, swim, bathe, or exercise without causing any problems. However, do not rub the patch while you are doing these activities.
  • If a patch falls off, try to stick it back on. If it will not stay in place, apply a new patch, but still follow your usual patch-changing schedule.
  • After you have removed a patch, fold it in half and dispose of it out of the reach of children and pets.
  • For the medication to work properly, it must be used as prescribed.
  • If you are unsure about anything related to your OTC oxybutynin patch dosage, talk to your healthcare provider, nurse, or pharmacist.
