What is Testosterone Undecanoate used for?

Nebido (testosterone undecanoate) is used in androgen replacement therapy to restore normal testosterone levels. - Male hypogonadism: restores physiological testosterone concentrations, improving sexual function, mood and muscle mass. - Testosterone deficiency: alleviates symptoms such as fatigue, loss of libido and reduced bone density. - Delayed puberty in males: supports development of secondary sexual characteristics when endogenous production is insufficient.

What are the side effects of Testosterone Undecanoate?

Nebido may be associated with a range of adverse reactions, which are classified by frequency and severity.

Common Side Effects: - Injection site pain: mild to moderate discomfort at the injection site. - Headache: transient headache. - Acne: increased sebaceous gland activity leading to acne. - Fluid retention: mild edema or weight gain.

Serious or Rare Side Effects: - Polycythemia: elevated red blood cell count that may increase thrombotic risk. - Cardiovascular events: rare occurrences of myocardial infarction or stroke. - Liver toxicity: abnormal liver function tests or hepatitis.

What precautions apply to Testosterone Undecanoate?

Before prescribing Nebido, clinicians should evaluate several safety considerations to minimise risks. - Cardiovascular assessment: review history of heart disease, hypertension or thromboembolic events. - Hematocrit monitoring: check red blood cell levels periodically to detect polycythemia. - Prostate evaluation: assess for benign prostatic hyperplasia or prostate cancer before initiating therapy. - Lipid profile: monitor cholesterol and triglycerides as androgen therapy may affect lipid metabolism. - Fertility counseling: discuss potential suppression of spermatogenesis with patients desiring future fertility. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

What does Testosterone Undecanoate interact with?

Nebido can interact with other medicines, altering its effectiveness or increasing adverse effects.

Major Interactions (Avoid): - Anticoagulants: increased risk of thrombosis due to polycythemia. - CYP3A4 inhibitors: may raise testosterone levels, enhancing androgenic effects. - Glucocorticoids: can exacerbate fluid retention and hypertension.

Moderate Interactions (Monitor Closely): - Insulin or oral hypoglycemics: testosterone may affect glucose control. - Antihypertensives: possible reduction in blood pressure efficacy. - Lipid‑lowering agents: monitor lipid profile as changes may occur.

Frequently asked questions

What is Nebido used for?+
Nebido is indicated for hormone replacement therapy in adult men with testosterone deficiency or male hypogonadism. It helps restore normal testosterone levels, improving symptoms such as low libido, fatigue, loss of muscle mass, and decreased bone density.
How does testosterone undecanoate work?+
Testosterone undecanoate is a long‑acting ester that, after intramuscular injection, is gradually hydrolysed to testosterone. The released testosterone binds to androgen receptors, influencing gene expression that drives androgenic and anabolic processes throughout the body.
What is the usual dose of Nebido?+
The dosing regimen for Nebido is determined by the prescribing clinician based on the patient’s clinical condition, laboratory values and treatment goals. The prescriber sets the dose and interval according to approved guidelines and individual response.
Is Nebido safe during pregnancy or breastfeeding?+
Nebido is intended for use in adult men and is not indicated for women who are pregnant or breastfeeding. There is insufficient data on safety in these populations, and the product should be avoided in such cases.
How do I order Nebido from GNH USA?+
To order Nebido, submit an enquiry on the product page at gnh-usa.com with the required quantity. GNH USA supplies hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details (including cold‑chain where required) and import documentation.
How does Nebido compare with other testosterone therapies?+
Nebido provides a long‑acting intramuscular formulation that requires fewer injections (typically every 10‑12 weeks) compared with shorter‑acting testosterone esters that may need weekly or bi‑weekly dosing. This can improve convenience and adherence while delivering stable testosterone levels.
How should Nebido be stored and handled?+
Nebido should be stored at 2‑8 °C in a refrigerator, protected from light. Do not freeze or shake the vial. Keep the product in its original packaging until use to maintain stability and potency.
How is Nebido administered?+
Nebido is given as an intramuscular injection, usually into the gluteal muscle. The injection is performed by a qualified healthcare professional using aseptic technique, and the dosing interval is set by the prescriber.
What are the most serious risks to watch for?+
Serious risks include polycythemia (elevated red blood cell count), cardiovascular events such as myocardial infarction or stroke, and liver toxicity. Patients should be monitored regularly for hematocrit, cardiovascular status and liver function.
Who should not use Nebido?+
Nebido is contraindicated in men with known hypersensitivity to testosterone undecanoate or any excipients, those with prostate or breast cancer, uncontrolled heart failure, severe liver disease, or untreated severe sleep apnea. It should also be avoided in women who are pregnant or lactating.
