Deca-Durabolin is a clear, yellow, oily solution for injection containing 50 mg/ml of nandrolone decanoate as the active substance.
The active substance of the medicine, nandrolone decanoate, belongs to a group of medicines called anabolic steroids.

  • in the treatment of osteoporosis (bone tissue loss)
  • as a supplement to specific treatment and dietary recommendations in disease states characterized by a negative nitrogen balance.

Note: Therapy with Deca-Durabolin does not replace therapy with other medicines.

2. Important information before using Deca-Durabolin

  • if the patient is allergic to nandrolone decanoate or any of the other ingredients of this medicine (listed in section 6 "What Deca-Durabolin contains").

  • if the patient is pregnant or thinks she may be pregnant (see section 2 "Pregnancy, breastfeeding and fertility").
  • if the patient has or has had a tumor of the prostate or breast or if there is a suspicion of these tumors.
  • in children under 3 years of age.

Warnings and precautions

Before starting treatment with Deca-Durabolin, the patient should discuss it with their doctor or pharmacist.
The medicine may cause the appearance of male characteristics in women (masculinization) (e.g. deepening of the voice, change in body shape, hair growth on the face and torso, frontal baldness, as well as changes in the external genitalia). If any symptoms of masculinization occur, the patient should immediately contact their doctor.
The use of anabolic steroids may cause prostate enlargement, especially in older men. Therefore, the doctor will regularly perform a digital rectal examination of the prostate and measure the level of prostate-specific antigen (PSA) in the blood.
Additionally, regular blood tests will be performed to measure the substance responsible for carrying oxygen in the body (hemoglobin). In very rare cases, the number of red blood cells increases so much that it causes complications.
Medical examinations may also be necessary in other cases. Therefore, before starting treatment with this medicine, the patient should inform their doctor or pharmacist if they have ever had, are currently experiencing, or suspect:

  • breast cancer with bone metastases;
  • kidney or lung cancer;
  • heart disease;
  • kidney disease;
  • liver disease (including jaundice);
  • high blood pressure;
  • diabetes;
  • epilepsy;
  • migraine, headache;
  • prostate problems, such as difficulty urinating.

Children and adolescents

The safety and efficacy of this medicine in children and adolescents have not been established.
Treatment of children before puberty should be carried out under the supervision of a doctor (see section 2 "Warnings and precautions").

Deca-Durabolin and other medicines

The patient should tell their doctor or pharmacist about all medicines they are currently taking or have recently taken, as well as any medicines they plan to take. This includes medicines without a prescription.
Other medicines may affect the action of Deca-Durabolin or Deca-Durabolin may affect the action of other medicines. Therefore, the patient should tell their doctor or pharmacist if they are taking or plan to take:

  • insulin and/or other medicines that regulate blood sugar levels;
  • erythropoietin (a medicine that reduces the symptoms of anemia);
  • medicines used to reduce blood clotting (anticoagulant medicines).

The use of anabolic steroids such as Deca-Durabolin may require a reduction in the doses of these medicines.
The patient should also inform their doctor or pharmacist if they are taking or plan to take hormones ACTH or corticosteroids (used to treat various diseases, such as rheumatic diseases, arthritis, allergic diseases, and asthma). The use of anabolic steroids such as Deca-Durabolin may increase the risk of water retention in the body, especially if heart or liver function is impaired.
Anabolic steroids may also affect the results of some laboratory tests (e.g. thyroid function). For this reason, the patient should tell their doctor or laboratory staff about taking this medicine.

Using Deca-Durabolin with food and drink

Consuming meals and drinks does not affect the action of this medicine.

Pregnancy, breastfeeding, and fertility

Do not administer to small children (under 3 years of age) for more than a week without a doctor's or pharmacist's recommendation.
