Monitoring

Your veterinarian will need to monitor your dog’s T4 levels periodically during the course of treatment. This requires taking a blood sample and measuring the amount of T4 in the blood. After starting Leventa, your veterinarian will evaluate peak blood T4 levels every 4 weeks, 4-6 hours after administration of Leventa until the correct dose is determined.


Once the correct dose is determined, your veterinarian will measure peak T4 levels every 6 months.
