Additional Information

Precautions

• Do Not Store Reconstituted: Mix only what is needed and use it right away; any leftover reconstituted solution must be thrown out immediately.
• Human Safety: Keep away from children as this product contains a potent hormonal agent that is not intended for human use.

Possible Side Effects

• Anaphylactic Reaction: A rare but serious systemic reaction can follow IM injection; always have epinephrine ready before giving the dose.
• Injection Site Reaction: Some cows develop local irritation or mild swelling at the injection site after receiving this protein-based injectable.

Frequently Asked Questions

Q1: What is Chorulon chorionic gonadotropin injection used for in cattle?

Ans: Cows with cystic ovaries can get stuck in a cycle of constant or near-constant heat, and Chorulon is the FDA-approved prescription injection used to break that pattern. It works by mimicking the hormone that causes the problem follicle to resolve, which brings the cow's reproductive cycle back on track.

Q2: What is the correct dose of Chorulon hCG for cows?

Ans: One full reconstituted vial, which comes out to 10,000 IU, goes in as a single deep IM injection per treatment. If the cow is still showing signs or the ovarian exam does not look right, the same dose can be given again two weeks out.

Q3: Is there a milk or meat withdrawal period for Chorulon cattle injection?

Ans: There is no milk discard or waiting period before slaughter with this product, which is a real plus for both beef and dairy herds. Cattle can stay in regular production right after treatment without any downtime built in around the injection.

Q4: How should Chorulon freeze-dried hCG be reconstituted before use?

Ans: Pour the full diluent vial into the powder vial and swirl gently until everything is dissolved into a 10 mL, 10,000 IU solution. Give the whole thing right away once it is mixed up; anything left over gets thrown out and cannot be set aside for a later dose.

Q5: Can an anaphylactic reaction occur after Chorulon chorionic gonadotropin injection in cows?

Ans: Yes, it is possible in rare cases because chorionic gonadotropin is a protein. Epinephrine should always be within reach before giving the injection, and an antihistamine may also be needed if a reaction develops. Getting epinephrine in fast is the priority if anaphylaxis occurs.
