Trulicity Tracker - log injections, weight, and side effects
Trulicity is a once-weekly injection of dulaglutide. This page explains how to track a Trulicity treatment with Dosley and links every medical fact to the FDA-approved label.
Trulicity is the brand name for dulaglutide, a once-weekly injectable medicine prescribed alongside diet and exercise to improve blood sugar in adults with type 2 diabetes. Because each treatment plan looks slightly different - different starting amounts, escalation steps, and side-effect timelines - keeping a personal log helps you and your prescriber see how things are going. Dosley is a private tracker for your injections, weight changes, and side-effect notes. It is not a medical device and does not give medical advice. The information below summarises the publicly available FDA-approved label so the page sits next to your tracker rather than inside it. If anything here differs from what your clinician has told you, follow your clinician.

Important safety information
Dulaglutide causes thyroid C-cell tumors in rats. It is unknown whether Trulicity causes thyroid C-cell tumors, including medullary thyroid carcinoma (MTC), in humans. Trulicity is contraindicated in patients with a personal or family history of MTC and in patients with Multiple Endocrine Neoplasia syndrome type 2. 1

Dosing and titration
Your prescriber decides every step on the schedule below. The summary here is for orientation while you log treatments - it is not a recommendation.
Treatment begins at 0.75 mg once weekly. The prescriber may increase to 1.5 mg for additional glycemic control, then to 3 mg, and to a maximum of 4.5 mg once weekly, with at least four weeks on the current amount before any further increase. 1
Trulicity does not have a fixed escalation interval. The prescribing information says any increase happens at the prescriber's discretion when additional glycemic control is needed, after at least four weeks on the current amount. 1
When you record a treatment in Dosley, you can attach the amount, the day, and any notes about how you tolerated it. The app does not change your schedule - it only records what your prescriber has set.
Injection sites and storage
Trulicity is given by subcutaneous injection in the abdomen, thigh, or upper arm. Rotating sites between treatments is recommended in the prescribing information. 1
Pens should be kept refrigerated between 2°C and 8°C until use. The room-temperature in-use period is set by the prescribing information - follow the limit printed on your packaging or in the patient leaflet. 1
Tracking injection sites and storage windows in Dosley is optional but useful - it gives you a quick view of which sites you have used recently and when a pen needs to be retired or moved.
The Trulicity pen
Each Trulicity pen is single-use and prefilled with one weekly amount of medicine. The needle is built into the pen and the pen is designed to be used directly out of the carton without priming. 1
This means there is one pen for one weekly injection. After the injection, the pen is finished and disposed of according to the leaflet - there are no remaining uses to count.
In Dosley, this shows up as a simpler weekly entry: pick the day, the amount, the site, and you are done. There is no per-pen counter to maintain.
Missed dose
If a Trulicity injection is missed, the FDA label says it can be taken as soon as possible if at least 3 days (72 hours) remain before the next scheduled day. If less than 3 days remain, skip the missed amount and resume on the next regular day. 1
About this medication and Dosley
How often is Trulicity injected?
Trulicity is a once-weekly subcutaneous injection. Your prescriber sets the day of the week and the amount; Dosley records what they have set so you can see your history. 1
What if I forget my Trulicity on the scheduled day?
The FDA-approved label says the missed amount may be taken as soon as possible if at least 3 days (72 hours) remain before the next scheduled day. If less than 3 days remain, the missed amount is skipped and you wait until the next regular day. If you are unsure, contact your clinician. 1
What are the most common Trulicity side effects?
In the FDA label's adverse-reaction tables, the most common side effects at the 1.5 mg amount were nausea (about 21%), vomiting (about 13%), diarrhea (about 13%), abdominal pain (about 9%), and decreased appetite (about 9%). Logging side effects in Dosley helps you and your prescriber spot patterns. 1
Do I need to prime the Trulicity pen before injecting?
No. The label states each Trulicity pen is single-use and is designed to be used directly without priming. Always follow the patient leaflet that came with your pen. 1
Where is Trulicity injected?
The label specifies subcutaneous injection in the abdomen, thigh, or upper arm, with site rotation. Dosley lets you tag the site for each entry so you can see at a glance where you have already injected. 1
How should Trulicity be stored?
The FDA label says Trulicity should be kept refrigerated between 2°C and 8°C until use. After it is taken out of the fridge, the pen has a room-temperature in-use window - check the leaflet that came with your pen for the exact number of days. 1
Does Dosley send my Trulicity data to my clinic?
No. Dosley is a personal tracker. Your treatment log lives in your Dosley account, and you choose whether to export it as a PDF to share with your clinician. Talk to your healthcare team before changing anything in your treatment. 1
How Dosley supports a Trulicity routine
Dosley is built for the small rituals of a once-weekly injection routine. The home screen shows your next scheduled day so you never have to count from the calendar, and a quick log entry takes about five seconds - pick the day, the amount you were prescribed, the site, and you are done.
Side-effect notes live next to each entry. Many people find that the early weeks of a new amount bring temporary changes in how they feel; logging those alongside the entry helps you and your prescriber see whether things are settling or whether the schedule needs adjusting.
Weight is tracked in the same place. Manual entry is two taps; a chart shows the trend rather than the daily noise, so a single bad-scale day does not break your week. If you use Apple Health, weight syncs automatically.
Because each Trulicity pen is a single weekly injection, there is no per-pen counter to maintain in the app. Dosley simply records each weekly entry and reminds you about the storage window in the leaflet you were given.
Everything stays on your device unless you choose otherwise. There is no clinic dashboard, no advertiser, and no requirement to create an account. If your healthcare team asks for a summary, you can export a PDF from the app and share it on your terms.
