What Is Androderm?

Androderm (testosterone transdermal system) topical (for the skin) is a naturally occurring male hormone used to treat conditions in men that result from a lack of natural testosterone.

What Are Side Effects of Androderm?

Common side effects of Androderm include:

  • redness, itching, burning, irritation, or hardened skin where the skin patch is worn;
  • breast swelling or tenderness,
  • increased acne or hair growth,
  • headache,
  • depressed mood, or
  • changes in your sex drive.

Tell your doctor if you have serious side effects of Androderm including:

  • burn-like blistering of the skin where the transdermal patch is worn,
  • skin irritation with patch-wearing that does not get better with time,
  • problems with urination,
  • swelling of your ankles,
  • frequent/prolonged erections,
  • nausea,
  • stomach pain,
  • low fever,
  • loss of appetite,
  • dark urine,
  • clay-colored stools, or
  • jaundice (yellowing of the skin or eyes).

Dosage for Androderm

The recommended starting dose is one Androderm 4 mg/day system (not two 2 mg/day systems) applied nightly for 24 hours.

What Drugs, Substances, or Supplements Interact with Androderm?

Androderm may interact with insulin, blood thinners, oxyphenbutazone, or corticosteroids. Other drugs may interact with Androderm topical. Tell your doctor all prescription and over-the-counter medications and supplements you use.

Androderm During Pregnancy and Breastfeeding

Women should not use this medication. Therefore, it is unlikely to be used during pregnancy or breastfeeding. Testosterone can cause birth defects in a fetus. A pregnant woman should avoid coming into contact with testosterone topical gel, or with a man's skin areas where a testosterone topical patch has been worn or the gel has been applied. If contact occurs, wash with soap and water right away.

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in practice.

Table 1 shows the adverse reactions that were reported by > 3% of 36 hypogonadal men who were treated with ANDRODERM 2 mg/day, 4 mg/day, or 6 mg/day for 28 days. Of note, all hypogonadal men studied had been stable users of topical testosterone replacement products prior to the study and there was no washout period between therapies. Furthermore, there was only one subject titrated to 6 mg/day and he withdrew from the study prematurely.

Table 1: Adverse Reactions Seen With the Use of ANDRODERM 2 mg/day, 4 mg/day, or 6 mg/day ( > 3%)

Adverse Reaction Overall
N = 36 %
Application site pruritus 17
Application site vesicles 6
Back pain 6

Other less common adverse reactions reported by < 3% of patients included: application site erythema, application site exfoliation, chills, diarrhea, fatigue, gastroesophageal reflux disease, hemarthrosis, hematuria, headache, polyuria, and prostatitis. The overall incidence of application site reactions of any kind was 28% (10 subjects with 13 adverse reactions).

No serious adverse reactions to ANDRODERM 2 mg/day and 4 mg/day were reported during the clinical trial.

Table 2 shows the adverse reactions that were reported in > 3% of 122 patients in clinical studies with ANDRODERM dosage strengths of 2.5 mg/day, 5 mg/day, and 7.5 mg/day. The most common adverse reactions reported were application site reactions. Transient mild to moderate erythema was observed at the site of application in the majority of patients at some time during treatment. The overall incidence of application site reactions of any kind was 48% (59 subjects with 107 adverse reactions).

Table 2: Adverse Reactions Seen With the Use of ANDRODERM 2.5 mg/day, 5 mg/day, or 7.5 mg/day ( > 3%)

Adverse Reaction Overall
N = 122 %
Application site pruritus 37
Application site blistering 12
Application site erythema 7
Application site vesicles 6
Prostate abnormalities 5
Headache 4
Contact dermatitis to system 4
Application site burning 3

The following reactions occurred in less than 3% of patients: rash, gastrointestinal bleeding, fatigue, body pain, pelvic pain, hypertension, peripheral vascular disease, increased appetite, accelerated growth, anxiety, confusion, decreased libido, paresthesia, thinking abnormalities, vertigo, acne, bullae at application site, mechanical irritation at application site, rash at application site, contamination of application site, prostate carcinoma, dysuria, hematuria, impotence, urinary incontinence, urinary tract infection, and testicular abnormalities.

Postmarketing Experience

The following adverse reactions have been identified during postapproval use of ANDRODERM. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
