What is Cernos?
Cernos is a naturally occurring sex hormone produced in a man's testicles. Small amounts of Cernos are also produced in a woman's ovaries and adrenal system.
Cernos is used in men and boys to treat conditions caused by a lack of this hormone, such as delayed puberty, impotence, or other hormonal imbalances. This medicine is not for use in treating low Cernos without certain medical conditions or due to getting older.
Cernos enanthate is used in women to treat breast cancer that has spread to other parts of the body (metastatic) and cannot be treated with surgery.
Cernos will not enhance athletic performance and should not be used for that purpose.
Cernos may also be used for purposes not listed in this medication guide.
Cernos indications
Cernos Gel 1% is indicated for replacement therapy in adult males for conditions associated with a deficiency or absence of endogenous Cernos:
- Primary hypogonadism (congenital or acquired): testicular failure due to conditions such as cryptorchidism, bilateral torsion, orchitis, vanishing testis syndrome, orchiectomy, Klinefelter's syndrome, chemotherapy, or toxic damage from alcohol or heavy metals. These men usually have low serum Cernos concentrations and gonadotropins (follicle-stimulating hormone [FSH], luteinizing hormone [LH]) above the normal range.
- Hypogonadotropic hypogonadism (congenital or acquired): gonadotropin or luteinizing hormone-releasing hormone (LHRH) deficiency or pituitary-hypothalamic injury from tumors, trauma, or radiation. These men have low Cernos serum concentrations, but have gonadotropins in the normal or low range.
Limitations of use:
- Safety and efficacy of Cernos Gel 1% in men with “age-related hypogonadism” (also referred to as “late-onset hypogonadism”) have not been established.
- Safety and efficacy of Cernos Gel 1% in males less than 18 years old have not been established.
Topical Cernos products may have different doses, strengths or application instructions that may result in different systemic exposure (1, 12.3).
How should I use Cernos?
Use Cernos solution as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- Cernos solution comes with an extra patient information sheet called a Medication Guide. Read it carefully. Read it again each time you get Cernos solution refilled.
- Prime this product before the first use. To prime it, depress the pump 3 times and wash any product that is dispensed down the sink.
- Depress the pump once to fill the applicator cup. Holding the applicator upright, wipe Cernos solution steadily up and down onto clean, dry skin in the armpit. If Cernos solution drips or runs, it can be wiped back up with the applicator cup. Do NOT apply Cernos solution to other parts of your body (eg, scrotum, penis, stomach, shoulders, upper arms). Do NOT apply it over open sores, wounds, or irritated skin.
- Do NOT use your fingers or hand to rub the medicine into the skin.
- You may need to alternate between armpits when applying Cernos solution. Be sure you understand how to apply Cernos solution. Contact your doctor or pharmacist if you have questions or concerns about how to apply Cernos solution.
- Wash your hands with soap and water immediately after using Cernos solution.
- Allow Cernos solution to dry completely before dressing.
- After Cernos solution has dried, cover the application site (eg, with a shirt) to prevent others from coming into contact with Cernos solution. If direct skin-to-skin contact with another person is expected, wash the application site well with soap and water to remove the medicine.
- After using Cernos solution, rinse the applicator with room temperature water and pat it dry with a tissue. Replace the applicator and cap on the bottle for storage.
- Do NOT get Cernos solution in your eyes. If you do, rinse thoroughly with water. If eye irritation persists, contact your doctor.
- Apply Cernos solution at the same time every morning after showering or bathing, unless your doctor tells you otherwise.
- If you are also using an antiperspirant or deodorant (stick or roll-on), apply it at least 2 minutes before you apply Cernos solution.
- For best results, wait 2 hours after applying Cernos solution before you wash the application site or swim.
- If you miss a dose of Cernos solution, use it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not use 2 doses at once.
Ask your health care provider any questions you may have about how to use Cernos solution.
Uses of Cernos in details
Cernos is a male hormone primarily used to treat deficiency or absence of naturally produced hormone Cernos in men (hypogonadal disorders). The conditions include,
- Testicular diseases (primary hypogonadism) - diseases or conditions of testes, the organ that produces Cernos affecting secretion of Cernos.
- Pituitary diseases (secondary hypogonadism) - diseases or conditions of pituitary gland or hypothalamus that produce hormones (gonadotropins) which stimulate release of Cernos.
Cernos description
Cernos is a steroid sex hormone found in both men and women. In men, Cernos is produced primarily by the Leydig (interstitial) cells of the testes when stimulated by luteinizing hormone (LH). It functions to stimulate spermatogenesis, promote physical and functional maturation of spermatozoa, maintain accessory organs of the male reproductive tract, support development of secondary sexual characteristics, stimulate growth and metabolism throughout the body and influence brain development by stimulating sexual behaviors and sexual drive. In women, Cernos is produced by the ovaries (25%), adrenals (25%) and via peripheral conversion from androstenedione (50%). Testerone in women functions to maintain libido and general wellbeing. Cernos exerts a negative feedback mechanism on pituitary release of LH and follicle-stimulating hormone (FSH). Cernos may be further converted to dihydrotestosterone or estradiol depending on the tissue.
Cernos dosage
Cernos (Cernos (transdermal)) TTS
One system is applied at about the same time each day. The adhesive side of the Cernos (Cernos (transdermal)) TTS system should be placed on a clean, dry area of skin on the arm, back or upper buttocks immediately upon removal from the protective pouch. DO NOT APPLY TO THE SCROTUM. The area selected should not be oily, damaged, or irritated. The system should be pressed firmly in place with the palm of the hand for about 10 seconds, making sure there is good contact, especially around the edges. In the event that a system should fall off, the same system may be reapplied. If the system comes off after it has been worn for more than 12 hours and it cannot be reapplied, a new system may be applied at the next routine application time. In either case, the daily treatment schedule should be continued. The Cernos (Cernos (transdermal)) TTS system should be worn approximately 24 hours and then replaced. To ensure proper dosing, serum Cernos concentration may be measured 2-4 hours after an application of Cernos (Cernos (transdermal)) TTS. If the serum Cernos concentrations are low, the dosing regimen may be increased to 2 systems. Because of variability in analytical values among diagnostic laboratories, all Cernos measurements should be performed at the same laboratory.
Cernos (Cernos (transdermal)) and Cernos (Cernos (transdermal)) WITH ADHESIVE
Patients should start therapy with a 6 mg/d system of either Cernos (Cernos (transdermal)) or Cernos (Cernos (transdermal)) WITH ADHESIVE applied daily; if the scrotal area cannot accommodate a 6 mg/d system, a 4 mg/d Cernos (Cernos (transdermal)) system should be used. One Cernos (Cernos (transdermal)) or Cernos (Cernos (transdermal)) WITH ADHESIVE system should be placed on clean, dry, scrotal skin. Scrotal hair should be dry-shaved for optimal skin contact. Chemical depilatories should not be used. Cernos (Cernos (transdermal)) or Cernos (Cernos (transdermal)) WITH ADHESIVE should be worn 22-24 hours.
After 3-4 weeks of daily system use, blood should be drawn 2-4 hours after system application for determination of serum total Cernos. Because of variability in analytical values among diagnostic laboratories, this laboratory work and later analyses for assessing the effect of the Cernos (Cernos (transdermal)) and Cernos (Cernos (transdermal)) WITH ADHESIVE therapy should be performed at the same laboratory.
If patients have not achieved desired results by the end of 6-8 weeks of treatment with any of the Cernos (Cernos (transdermal)) products, another form of Cernos replacement therapy should be considered.

Cernos interactions
See also:
What other drugs will affect Cernos?
Drug Interactions
Anticoagulants: C-17 substituted derivatives of Cernos, such as methandrostenolone, have been reported to decrease the anticoagulant requirements of patients receiving oral anticoagulants. Patients receiving oral anticoagulant therapy require close monitoring, especially when androgens are started or stopped.
Oxyphenbutazone: Concurrent administration of oxyphenbutazone and androgens may result in elevated serum levels of oxyphenbutazone.
Insulin: In diabetic patients, the metabolic effects of androgens may decrease blood glucose and therefore, insulin requirements.
Propranolol: In a published pharmacokinetic study of an injectable Cernos product, administration of Cernos cypionate led to an increased clearance of propranolol in the majority of men tested.6
Corticosteroids: The concurrent administration of Cernos with ACTH or corticosteroids may enhance edema formation; thus these drugs should be administered cautiously, particularly in patients with cardiac or hepatic disease.7
Drug/Laboratory Test Interactions
Androgens may decrease levels of thyroxin-binding globulin, resulting in decreased total T. Free thyroid hormone levels remain unchanged, however, and there is no clinical evidence of thyroid dysfunction.
The Cernos (Cernos (transdermal)) products contain a Schedule III controlled substance as defined by the Anabolic Steroids Control Act.
Cernos (Cernos (transdermal)) TTS is designed for application to arm, back or upper buttocks skin.
Cernos (Cernos (transdermal)) and Cernos (Cernos (transdermal)) WITH ADHESIVE are designed for application to scrotal skin only. Because scrotal skin is at least five times more permeable to Cernos than other skin sites, Cernos (Cernos (transdermal)) or Cernos (Cernos (transdermal)) WITH ADHESIVE will not produce adequate serum Cernos concentrations if applied to non-scrotal skin.
Ingestion of Cernos, or the contents of any of the Cernos (Cernos (transdermal)) products will not result in clinically significant serum Cernos concentrations due to extensive first-pass metabolism. In addition, an intramuscular injection of Cernos from any of the Cernos (Cernos (transdermal)) products will not produce adequate serum Cernos levels due to its short half-life (about 10 minutes).

Adverse Events with Cernos (Cernos (transdermal))
In clinical studies of 104 patients treated with Cernos (Cernos (transdermal)), the most common adverse effects reported were local effects. In US clinical trials, most of the 72 patients filling out a daily questionnaire reported scrotal itching, discomfort, or irritation at some time during therapy. Of all the daily questionnaire responses, 7% reported itching, 4% discomfort, and 2% irritation. All topical reactions decreased with duration of use.
The following adverse effects (greater than 1%) were reported in association with Cernos (Cernos (transdermal)) therapy in 104 patients using the product for up to three years. These effects are listed in decreasing frequency of occurrence with the percentages of patients reporting the effect in parentheses: Gynecomastia (5%), acne (4%), prostatitis/urinary tract infection (4%), breast tenderness (3%), stroke (2%). For this same patient population, the following adverse effects were reported by 1% of users: memory loss, pupillary dilation, abnormal liver enzymes, scrotal cellulitis, deep vein phlebitis, benign prostatic hyperplasia, rectal mucosal lesion over prostate, hematuria/bladder cancer, papilloma on scrotum, and congestive heart failure.
Adverse Events with Cernos (Cernos (transdermal)) WITH ADHESIVE
In a pharmacokinetic study in 50 normal men, skin assessment scores following a single 24-hour application of Cernos (Cernos (transdermal)) WITH ADHESIVE to scrotal skin were similar to those for Cernos (Cernos (transdermal)). Other adverse events reported during the study were headache (6%), dizziness (6%), back pain, pain, nausea, and pustular rash (1% each).
General Adverse Events with Androgen Replacement Therapy
Skin and Appendages: Hirsutism, male pattern baldness, seborrhea, and acne.
