Androderm (Testosterone) – Transdermal

What Is Androderm?

Androderm (testosterone) is a prescription transdermal patch that is used to replace endogenous (caused by internal factors) testosterone in adult males 18 and older who have little to no existing levels of endogenous testosterone as a result of certain medical conditions, such as primary hypogonadism or hypogonadotropic hypogonadism.

Androderm contains the ingredient testosterone, which is in a drug class called androgens.

Androgens are also known as sex hormones. In addition to boosting testosterone, these sex hormones can be used to increase reproductive ability, bone growth, and body hair development.

Androderm's testosterone replacement treatment helps with the development and maintenance of male features, such as body hair, sex organs, vocal cords, and body fat distribution.

No therapeutic (generic or brand-name) equivalent to Androderm currently exists.

This article will highlight Androderm, a brand-name drug, as a prescription transdermal patch that is applied to the skin.

What Is Androderm Used For?

The Food and Drug Administration (FDA) has approved Androderm as a testosterone replacement therapy for adult males with medical conditions associated with little to no endogenous testosterone, including:

  • Primary hypogonadism (congenital or acquired): A decrease in sperm and/or testosterone production due to a disease of the testes
  • Hypogonadotropic hypogonadism (congenital or acquired): A decrease in sperm and/or testosterone production due to a disease of the pituitary gland or hypothalamus

Androderm has not been studied in men with age-related hypogonadism (low testosterone levels due to aging).

Androderm is not for use in people assigned female at birth and could cause harm to an unborn baby if used by a parent during pregnancy.

How to Use Androderm

If you are prescribed Androderm:

Use Androderm exactly as directed by your provider. Your provider will tell you how many patches to apply and when to apply them. Do not change your dose unless your healthcare provider instructs you to do so.

Apply Androderm at approximately the same time every night. After applying, wait at least three hours before taking a bath or shower, or going swimming.

Sweating a lot, such as during intense exercise, may cause your patch to become loose and/or fall off. If the patch becomes loose, rub your finger around the edges to secure it again.

Do not use tape. If the patch falls off, and it is before 12 p.m., put on a new patch and wear it until it is time to change your patch at the regular time in the evening.

If the patch falls off after 12 p.m., do not apply a new patch. Wait and put on a new patch at your regular time.

Change your patch every 24 hours. Remove the old patch before applying a new patch. Change the site where you place your patch every day. Do not use the same site for at least seven days.

You may notice skin redness after removing a patch. If this does not go away, notify your healthcare provider.

Androderm contains aluminum and must be taken off before a magnetic resonance imaging scan (MRI) to prevent burns.

Do not use Androderm if the pouch seal is broken or if there is any damage to the patch. Discard the patch and use a new one. Before applying Androderm, ensure the skin you're applying it to is clean and dry.

Make sure there is no broken skin. Avoid areas of skin that are oily, hairy, or where you may sweat. You can place the patch on your back, stomach, upper arm, or thigh.

Do not place an Androderm patch on any other parts of your body, such as the scrotum or buttocks.

When applying the patch, place it flat on the skin with the sticky side down and press down firmly around the edges. Make sure the patch sticks well to the skin.


Store at room temperature, away from heat, direct light, and moisture. Do not store it in the bathroom. Androderm contains testosterone and is a controlled (Schedule III) substance.

Keep this medication where no one else can get to it. Keep it out of the reach and out of the sight of children and pets. Keep Androderm in the sealed pouch until you are ready to use it.

To discard Androderm, fold the used patch in half, so the sticky sides stick together, and discard it in the household trash.

Off-Label Uses

Sometimes Androderm is used off-label for indications that are not FDA-approved.

Healthcare providers may prescribe a testosterone replacement such as Androderm to transgender men (females transitioning to males) to help develop male features and suppress female features.

Testosterone therapy is sometimes prescribed off-label for men who have low testosterone levels, and who are experiencing symptoms, to help replace testosterone and maintain secondary sex characteristics (such as body hair and muscle mass).

Although Androderm is not approved for age-related low testosterone, older adult males with symptoms may sometimes be prescribed testosterone replacement off-label if the benefits outweigh the risks.

Furthermore, while Androderm is not FDA-approved for use in females, some healthcare providers will prescribe it off-label for people who are postmenopausal (after menopause, when menstrual periods have stopped for at least 12 months in a row). In these cases, Androderm may be used alone or in combination with estrogen to treat hypoactive sexual desire disorder (HSDD), also known as female sexual interest/arousal disorder

How Long Does Androderm Take to Work?

In clinical trials, the majority of males who used Androderm had normal testosterone levels within 28 days.

Generally, clinical studies have shown testosterone replacement to start to take effect at around three to four weeks, but it may take several months for the maximum effect to be seen.

What Are the Side Effects of Androderm?

This is not a complete list of side effects, and others may occur. A healthcare provider can advise you on side effects. If you experience other effects, contact your pharmacist or healthcare provider. You may report side effects to the FDA at or 800-FDA-1088.

Common Side Effects

The most common side effects of Androderm are:

Serious Side Effects

Call your healthcare provider right away if you have serious side effects.

Call 911 if your symptoms feel life-threatening or if you think you’re having a medical emergency. Serious side effects and their symptoms can include the following:

  • Hypersensitivity reaction or anaphylaxis: Symptoms can include a rash, hives, swelling around the lips, tongue, and face, and difficulty breathing, which require emergency medical attention.
  • Severe application-site reaction
  • Pulmonary embolism (PE; blood clots in the lungs): Be alert to chest pain, cough, wheezing, fast breathing, or coughing up blood.
  • Blood clots in an arm or leg: Be alert to swelling, warmth, or redness in an arm or leg
  • Possible increased risk of heart attack or stroke.
  • Worsening of heart failure: Be aware of the potential for shortness of breath, or fast weight gain.
  • Benign prostatic hyperplasia (BPH): BPH is an enlarged prostate gland that can cause urinary symptoms such as frequent urination, waking up to urinate, dribbling after urination, and inability to empty the bladder.
  • Polycythemia: This is a high concentration of red blood cells.
  • Priapism: This condition causes a prolonged and/or painful erection.
  • Prostate cancer
  • Sleep apnea: Apnea is a dangerous sleep disorder in which breathing stops and restarts throughout the night.
  • Blood in the urine
  • The potential for abuse and dependence

Long-Term Side Effects

There is little information on the long-term use of Natesto.

However, there is more information about the long-term use of testosterone in general:

Clinical guidelines from the American College of Physicians, published in the Annals of Internal Medicine in 2020, noted that in 20 studies (with a follow-up ranging from less than one year to over ten years), there was no increased risk of death, heart events (such as stroke or heart attacks), prostate cancer, or blood clots in the lungs or legs.

However, the study also noted that there is a lack of evidence of long-term safety and that most studies did not include men with heart disease.

Subsequently, the best course of action would be to consult your healthcare provider, who can consider your individual factors like age, medical conditions, and symptoms, and weigh the risks vs. benefits of testosterone treatment.

Report Side Effects

Androderm may cause other side effects. Call your healthcare provider if you have any unusual problems while taking this medication. If you experience a serious side effect, you or your provider may send a report to the FDA MedWatch Adverse Event Reporting Program or by phone (800-332-1088).

    • For hormone replacement:
      • Adults—At first, one 4-milligram (mg) patch applied nightly for 24 hours. Your doctor may adjust your dose as needed.
      • Children—Use and dose must be determined by your doctor.


Potential users should be aware of the following before starting treatment with Andoderm:

Older adults: Males 65 and older should consult their healthcare provider regarding the use of Androderm as there is not enough information in this age group to determine the risk of heart problems and prostate cancer.

Use in females/pregnant and breastfeeding females: Natesto is not approved for use in females of any age (and if used in pregnant/breastfeeding people, Androderm could cause serious harm to the unborn fetus).

Children: Androderm is only approved for use in adult males and should not be used in adolescents under 18 years old.

Kidney/liver issues: Androderm has not been studied in people with kidney or liver problems. Therefore, people with any type of kidney or liver impairment should consult their healthcare provider before starting treatment.

Missed Dose

If you miss your regularly scheduled time, apply the patch as soon as you remember. If it is almost time for the next dose, skip the missed dose.

Continue with your regular schedule. Do not apply extra patches to try to make up for a missed dose. In the event that the patch becomes loose, rub your finger firmly around the edges of the patch to secure it.

If a patch falls off, and it is before 12:00 p.m., put on a new patch and wear it until the evening, when you normally change your patch. If the patch falls off later in the day, wait until the evening and replace the patch.

If you are not sure what to do, consult with your healthcare provider.

Overdose: What Happens If I Use Too Much Androderm?

Wearing too many Androderm patches, or wearing your patches for too long, may cause you to absorb too much testosterone, which may cause symptoms of an overdose, such as decreased libido, impaired erectile function (ED), fatigue, and depression.

What Happens If I Overdose on Androderm?

If you think you or someone else may have overdosed on Androderm, call a healthcare provider or the Poison Control Center (800-222-1222). If someone collapses or isn't breathing after taking Androderm, call 911 immediately.

    Before using Androderm, review your medication list with your healthcare provider.

How Can I Stay Healthy While Using Androderm?

Androderm contains testosterone and is a controlled substance.

This type of testosterone is not used to enhance athletic performance and should not be used for that purpose. It is used in males with certain medical conditions who do not make any, or enough, testosterone. Keep it in a place where no one can get to it.

Topical testosterone can be absorbed through the skin and can cause male features to develop in a woman or child who comes into contact with it. It can also cause harm to an unborn baby and should not be used or handled by pregnant people.

Pregnant people also should not come into contact with the male's skin where the medication has been applied.

If anyone in close contact with you, such as a family member, friend, or caregiver, develops symptoms such as enlarged genitals, increased sex drive, aggression, hair loss, excessive body hair, acne, or irregular periods, contact your healthcare provider.

Some other tips to remember to use Androderm safely and effectively include:

  • Do not use any lotions or skin products where you will apply the patch. This may prevent the patch from staying securely on the skin.
  • Do not swim or shower for at least three hours after applying an Androderm patch. You may need to develop a new regimen for showering to accommodate the timing.
  • If you need an MRI, Androderm should be removed before the scan because it could cause a skin burn.
