The active substance of T4 is levothyroxine sodium. Each drop contains 5 μg of levothyroxine sodium. Each 1 ml of oral drops contains 100 μg of levothyroxine sodium or 20 drops.

Instructions for use:

  1. Shake the vial well before use.
  2. The user should turn the vial upside down in a vertical position. The vial should be strictly in a vertical position to start the flow.
  3. If the flow is delayed, the user will need to tap the bottom of the vial before running the first 2-3 drops before using the medicine. These drops should not be used. Once the flow of the drops from the vial is normalized, the user can start using the medicine normally, calculating the correct dosage.
