# Customising Medication Types and Units

Entering item details in Ampoule should be as quick and simple as possible. You can enter values manually, but you can also save you own presets that can be selected quickly.

Tap *Custom Types and Units* on the *Settings* tab to get started.

You can also do the same for the *Units* field, if the presets are not enough. Maybe you need something obscure like *mg/mmol*, *kilodaltons* or *Becquerels*!
