Product Introduction:
Cresp 40mcg Injection is a prescription medication used to treat anemia associated with chronic kidney disease (CKD) and chemotherapy-induced anemia. It helps to reduce the need for blood transfusions by stimulating the production of red blood cells in the bone marrow. This medication is administered as an injection under the skin (subcutaneous) or into a vein (intravenous).
Uses of Cresp 40mcg Injection:
Cresp 40mcg Injection is primarily used to treat:
-
Anemia due to Chronic Kidney Disease (CKD) – Helps increase red blood cell count in patients with kidney failure.
-
Chemotherapy-induced Anemia – Prevents and treats anemia in cancer patients undergoing chemotherapy.
-
Anemia in HIV Patients on Zidovudine Therapy – Used in specific cases to manage anemia in HIV patients.
-
Before Surgery for Certain Patients – To reduce the need for blood transfusion in certain surgical procedures.
-
Anemia in Bone Marrow Disorders – Used in specific cases such as myelodysplastic syndromes.
-
Anemia Related to Other Chronic Diseases – In some cases, it may be prescribed for other anemia-related conditions.
Storage Instructions:
-
Store in a refrigerator at 2°C to 8°C.
-
Do not freeze or shake the pre-filled syringe.
-
Protect from direct sunlight and heat.
-
Keep it out of reach of children.
How Cresp 40mcg Works (Mechanism of Action):
Darbepoetin Alfa is a recombinant human erythropoietin analog that stimulates erythropoiesis (red blood cell production). It works by binding to erythropoietin receptors on bone marrow cells, which promotes the proliferation and differentiation of red blood cell precursors. This helps increase hemoglobin levels and reduces the need for blood transfusions in anemic patients.

Seek immediate medical attention if you experience severe side effects.
Dosage (Typical Recommended Dose):
-
For Chronic Kidney Disease (CKD):

Monitor hemoglobin levels regularly – High hemoglobin can increase the risk of cardiovascular issues.
-
Do not use if you have uncontrolled high blood pressure.
-
Not recommended for patients with pure red cell aplasia.
-
Use with caution in pregnant and breastfeeding women.
-
Avoid if you have a history of blood clots or stroke.

Inform your doctor if you are undergoing surgery, as it may increase clotting risk.
Drug Interactions:
Cresp 40mcg Injection may interact with:
-
Blood pressure medications (e.g., antihypertensives) – May require dose adjustments.
-
Blood thinners (anticoagulants) (e.g., warfarin, heparin) – May increase clotting risk.
-
Iron supplements – Iron levels should be monitored, as adequate iron stores are necessary for the medicine to work effectively.
-
Chemotherapy drugs – May require dose modifications.
Always inform your doctor about all the medications you are taking.
