Quoted from the US label · Unopened vs in use · Travel · Sources · Reviewed

Short answer: Keep Zomacton vials in the fridge at 36-46°F (2-8°C), in the carton to protect them from light, and do not let the diluent freeze. Once mixed with its own diluent, a 5 mg vial keeps in the fridge for up to 14 days and a 10 mg vial for up to 28 days. Do not freeze mixed vials. Source: Zomacton label, section 16.2.

What does the Zomacton label say?

Section 16.2, before reconstitution: “Store ZOMACTON vials refrigerated at 36° to 46°F (2° to 8°C) in the original carton to protect from light. Avoid freezing the accompanying diluent.”

The mixed-vial days apply to a vial mixed with its co-packaged diluent. The label does not give a room-temperature allowance for Zomacton.

How do you handle mixed vials at home?

  • Instructions for Use: “Write the date you mixed the growth hormone on the vial label. The 5 mg vial must be used within 14 days. The 10 mg vial must be used within 28 days.”
  • Store mixed and unopened vials in the refrigerator at 36-46°F (2-8°C). Do not freeze.
  • Before each dose, check that the solution is clear and the mixing date is within 14 days (5 mg) or 28 days (10 mg).
  • The cartons say: gently swirl, do not shake.

How do you travel with it?

Zomacton has no room-temperature allowance on its label, before or after mixing. Carry vials in an insulated bag with a cold pack, in the carton, without letting them touch the pack.

  • TSA allows medically necessary liquids over 3.4 oz in carry-on bags; declare them at the checkpoint for inspection.
  • Unused syringes and pen needles are allowed when they travel with the injectable medicine.
  • Ice packs and gel packs that keep medicine cool may go through frozen, partly frozen or melted.
  • Keep medicine in your carry-on, not checked luggage, where you cannot control the temperature. Do not let it touch an ice pack directly, since most labels say do not freeze.
