Can You Overdose Chickens on Corid

Can You Overdose Chickens on Corid? [SEE HERE]

Corid, or amprolium, is commonly used to treat coccidiosis in chickens. Coccidiosis is an intestinal parasitic disease caused by a protozoan.

When used correctly, Corid can be an effective remedy against this ailment.

However, like all medications, there’s a potential for overdosing, which can have implications for your chickens.

1. How Does Corid Work?

Corid works by mimicking thiamine (Vitamin B1), which the coccidia parasite requires to multiply.

By inhibiting the absorption of thiamine, Corid effectively starves the parasite, halting its growth and spread.

2. Overdosing Risks

Given that Corid acts by blocking thiamine absorption, prolonged use or excessive dosages could potentially result in thiamine deficiency in chickens.

Thiamine is vital for various metabolic processes, and a deficiency can lead to neurological issues and other health problems.

3. Signs of Overdose

Chickens that have been overdosed on Corid or given the drug for an extended period may exhibit:

  • Lethargy or decreased energy
  • Loss of appetite
  • Weakness or difficulty walking
  • Neurological symptoms like tremors, convulsions, or paralysis

4. Prevention

To prevent overdosing:

  1. Follow Dosage Instructions: Always follow recommended dosages based on the product label or veterinarian advice.
  2. Limit Treatment Duration: Generally, treatment with Corid shouldn’t exceed the recommended days unless directed by a vet.
  3. Avoid Using with Other Meds: Combining Corid with other medications without veterinary guidance can amplify risks.

5. What to Do in Case of Overdose

If you suspect your chickens have been overdosed:

  1. Stop the Medication: Discontinue Corid treatment immediately.
  2. Administer Thiamine: If possible, give the chickens thiamine injections to counteract the effects. Always consult with a vet about dosages and administration.
  3. Hydrate and Support: Ensure your chickens are well-hydrated and have access to a balanced diet.
  4. Consult a Veterinarian: Always reach out to a veterinarian if you suspect an overdose. They can provide guidance on supportive care and recovery.


Corid can be a lifesaver for chickens affected by coccidiosis, but as with all medications, it should be used responsibly and in the correct dosages. If in doubt, always err on the side of caution and consult with a professional.

Proper care and attention to your flock’s health will ensure they remain happy, healthy, and productive.
