Abstract: A medication administration system includes an application assembly having a syringe assembly coupled within the application assembly. A trigger handle of the application assembly is operationally coupled to the syringe assembly such that actuation of the trigger handle actuates the syringe assembly. The syringe assembly is for administering medication to an animal. A needle assembly is in fluid communication with the syringe assembly. The needle assembly is for piercing the hide of the animal such that the syringe assembly is adapted for applying medication to a blood stream of the animal. A sling assembly is for carrying a medication supply assembly. The sling assembly is adapted for selectively coupling to a user. The medication supply assembly is in fluid communication with the syringe assembly such that the medication supply assembly is adapted for supplying medication to the syringe assembly.
