Deca Durabolin Injection: Uses and Side Effects

What is Deca Durabolin?

Deca Durabolin 50 mg comprises Nandrolone Decanoate as its primary and active component.

This oily, yellow-coloured solution is classified under a group of drugs known as anabolic steroids.

It is used in the treatment of osteoporosis and anaemia amongst women post-menopause, and other related disorders. 

Is Deca Durabolin an OTC or Prescription Drug?

It is a prescription drug.

Uses of Deca Durabolin

The most common uses of durabolin are:

Post-menopausal osteoporosis

The drug controls the adverse effects of osteoarthritis, a medical condition pertaining to the loss of bone tissue, amongst post-menopausal women. It imparts strength to the bones and improves bone density, thus, minimising the risk of bone fractures.

Anaemia amongst post-menopausal women

The drug is beneficial for preventing certain types of anaemia, especially amongst post-menopausal women who also have renal disorders.

Degenerative disorders

The drug is also prescribed to individuals with medical conditions that negatively affect their source of strength. These conditions related to weakened tissues are usually a result of an injury or prolonged illnesses.

All of this together helps treat post-menopausal osteoporosis and anaemia.
