Estradiol Spray (Lenzetto)

Lenzetto is a transdermal hormone therapy that delivers estradiol (a form of oestrogen) via a metered skin spray. 


How to Use Lenzetto


  1. Priming the device

    • When you start a new Lenzetto container, you must prime the pump by spraying 3 times with the plastic cover on.

    • Only prime when you first open a container – you don’t repeat for each daily dose.

  2. Applying the dose

    • Spray onto clean, dry skin on the inner forearm or inner thigh. 

    • Hold the device upright, rest the cone firmly on the skin, and press the button.

    • Do not rub in or massage the spray – just let it absorb naturally.

    • After spraying, wait at least 2 minutes before dressing to let it dry, and avoid skin-to-skin contact for 60 minutes to prevent transfer.

    • If someone (or a pet) accidentally touches the sprayed area before it’s dry, they should wash with soap and water immediately.

  3. Storage

    • Keep the spray out of children’s reach.

    • Do not refrigerate or freeze. Store below 25°C.

    • Because it contains ethanol, keep away from heat, flames, or sources of ignition.


Dosage

  • You will usually start on the lowest dose: 1 spray per day.

  • Depending on treatment response, this can be increased to 2 sprays/day, or up to a maximum of 3 sprays/day.

  • There’s a dose tracker on the Lenzetto packaging. Make sure to tick off sprays so you know how many are left. 

  • A device contains 56 sprays once primed.

Missed Dose

If you forget a dose:

  • Use it as soon as you remember — unless it’s nearly time for your next dose.

  • Do not double up to make up for a missed spray.

  • If you skipped one or more days, you’ll need to prime the pump again (spray three times with the cover on) before resuming.
