How to use Stazol Injection

Your doctor or nurse will give you this medicine. Kindly do not self administer.

How Stazol Injection works

Stazol 50 Injection reduces the release of a chemical called bradykinin, that is responsible for causing breaking and leakage of blood vessels. This damage to blood vessels leads to sudden accumulation of fluids below the skin causing swelling (edema) as well as redness. Stazol 50 Injection blocks the action of bradykinin and treats angioedema.

Quick tips

Tell your doctor if you have liver, kidney, or heart conditions, as Stazol 50 Injection may worsen fluid retention or increase strain on these organs.
Inform your provider if you have a history of prostate or breast cancer, since anabolic steroids like Stazol 50 Injection can accelerate tumor growth in hormone-sensitive conditions.
Watch for signs of liver issues such as dark urine, yellowing of skin/eyes, or abdominal pain, and report them immediately. Stazol 50 Injection carries a risk of liver toxicity.
Discuss any planned sports participation, as Stazol 50 Injection is banned in most athletic competitions and may lead to disqualification if detected.
Avoid alcohol or other liver-stressing substances during Stazol 50 Injection treatment, as combining them can amplify the risk of liver damage.
