What If I Forget to Use a Testosterone Patch?

If you forget to change your patch, change it as soon as you remember, unless it is almost time for your next application. In this case, skip the missed patch and continue with your regular schedule. Do not apply extra patches to make up for a missed dose.

How Does It Work?

Testosterone patches contain testosterone, the primary male sex hormone. Testosterone from the patch is absorbed through the skin and into the bloodstream over a 24-hour period. As a result, blood levels of testosterone increase.
With the patch, testosterone levels are highest in the morning and lowest at night. This pattern mimics the normal daily variation of testosterone levels observed in healthy young men. However, it is unknown if this effect is clinically significant.

When and How to Use This Medicine

Some general considerations to keep in mind during treatment with the testosterone patch include the following:
  • This medication comes in the form of a patch that is applied to the skin once a day.
  • The testosterone patch should be applied in the evening, between 8 p.m. and midnight. Try to apply it at around the same time each night.
  • Apply the patch to a clean, dry area of the skin on the back, stomach, upper arms, or thighs. Avoid areas that are oily, sweaty, or covered with hair. Also, avoid irritated skin, open sores, or bony areas that may be subject to pressure when you sleep or sit.
  • Never apply the testosterone patch to your scrotum (genitals).
  • Rotate the patch placement each day. Do not apply the patch to the same area of skin more than once a week.
  • Do not use a cut or damaged patch.
  • If the patch falls off before noon, replace it with a new patch and resume your normal dosing schedule. If the patch falls off later in the day, do not replace it. Instead, apply a new patch at your regular time.
  • You can use a nonprescription hydrocortisone cream to help relieve minor skin irritation after removing the patch. Your pharmacist can help you choose an appropriate product. A prescription for a more potent steroid cream may be necessary for stubborn cases. Do not use any kind of ointment (rather than cream), as this can affect testosterone absorption.
  • You do not need to remove your patch during sexual activity, bathing, or swimming.
  • For the medication to work properly, it must be used as prescribed.
