Medical disclaimer
VialBook is a tracking tool. It is not a medical device. It does not diagnose, treat, prevent, or cure any disease or condition, and it does not provide medical advice.
What VialBook does
- Stores the entries you choose to make on your phone.
- Shows your history, a weight chart with your dose changes marked, and a site log built from your own entries.
- Sends reminders on the schedule you set.
- Makes a summary PDF from what you logged, if you ask for one.
- Does arithmetic on numbers you type, such as vial math, and shows the math.
What VialBook does not do
- Tell you what medicine to take or what dose to take.
- Say whether your dose is safe or right for you.
- Replace a conversation with your doctor or pharmacist.
- Check the quality or source of any medicine.
- Send your data to anyone. It stays on your phone unless you export a file and share it yourself.
Injection sites
The site shown as suggested is the one you used least recently according to your own log. It is a convenience for rotating, not a recommendation about where to inject. Follow the instructions you were given by your doctor or pharmacist.
The numbers you enter
VialBook shows what you enter. If a number is wrong, the app cannot know. Always check your numbers against your prescription label and with your doctor or pharmacist before you take anything.
Emergencies
If you think you are having a medical emergency, call your local emergency number. Do not rely on this app.
