A Bydureon tracker is a record of each weekly injection, the site you used, and what followed it. Veya holds those together so a pattern is visible rather than recalled. It records what you enter and nothing more. It will not tell you what to take, and it does not replace your prescriber's advice.

Why Bydureon users track

The reason people start tracking is almost never curiosity. It is an appointment coming up, or a symptom that may or may not be connected to the injection several days ago, and no reliable way to tell.

The same active substance, at a completely different cadence to Byetta

Bydureon and Byetta share the same active substance, exenatide, but Bydureon is a prolonged-release formulation taken once weekly, where Byetta is immediate-release and taken twice a day. The difference in release profile is what allows the difference in cadence, and the two are not interchangeable pen for pen.

If you have ever been on the other one, it is worth being clear in your own record which formulation and cadence you were on and when you moved between them.

A weekly injection is easy to lose track of

A daily medicine attaches itself to a routine and a missed one is obvious by lunchtime. Bydureon adds a step the others do not have: it arrives as a powder and a solvent that have to be brought together before the injection, so the whole thing is a small procedure rather than a quick action, and a week where it felt rushed is worth knowing about later.

A logged date is the difference between knowing and reconstructing. It also gives every symptom you record afterwards something to be measured from.

Symptoms are only useful with a timeline attached

A prescriber can do a great deal with a date and very little with an adjective. Because the medicine is prolonged-release, what happens in the days after an injection is not the same question as what happens in the days after a Byetta dose, and a record is the only thing that tells the two patterns apart.

The date it began and the date it eased are the two facts that survive the walk to the appointment. Everything else about how it felt tends not to.

Your prescription changes, and the record has to survive it

Treatment is reviewed and adjusted. A change is only legible against what came before it, so the record has to predate the thing you want to understand.

A history that runs continuously across an adjustment is worth more than a detailed one that starts the week you noticed a problem.

How Veya tracks your Bydureon

  • Injection logThe date of each injection, with the site you used. The weekly cadence is visible as a pattern rather than held in your head.
  • Symptom and side-effect notesWhat you noticed, the day it started, and how long it went on. Entries sit on the same timeline as your injections, so the gap between the two is something you can see.
  • Weight and measurement entriesRecorded when you choose to record them, at whatever interval you and your prescriber find useful. Veya stores the numbers you enter and draws them over time.
  • Appointment preparationYour recent entries, gathered into something you can read out or hand over, so the appointment starts from a record rather than from trying to recall six weeks at once.
  • Reminders you setA prompt on the schedule you choose, for the things you have decided to record. Veya reminds you to make an entry; it has nothing to say about what your treatment should be.
  • CSV exportYour entries out of the app as a CSV file, in normal use and after cancelling. It is your record, and it should be readable somewhere that is not Veya.

What to record across a change in your prescription

Treatment is reviewed and adjusted over time. Veya will not tell you what to take, and this page carries no schedule of amounts: that is between you and your prescriber, and it is on the patient information supplied with your medicine. What a tracker can do is make the period around a change legible afterwards. These are the entries worth having.

  • The date something changed, recorded on the day rather than reconstructed later.
  • Which day of the week you inject, and whether it stayed the same through the change.
  • Whether the change involved moving from a different formulation of exenatide, and when that happened.
  • Any symptom that appeared, disappeared or changed character in the two weeks either side.
  • How long each symptom lasted, which is usually more informative than how bad it felt.
  • The injection site used each week, so a site-specific reaction can be told apart from a general one.
  • Anything else that changed at the same time: a new medicine, an illness, travel, a different sleep pattern.
  • The questions you want to ask at the next appointment, written down when they occur to you.

Read from the EMA summary of product characteristics for Bydureon, sections 1, 2, 4.2 and 5.1, on 11 September 2026. Product information is reissued when a variation is approved. Always follow the patient information leaflet supplied with your own medicine, and speak to your prescriber or pharmacist about anything concerning your treatment.

Does Veya tell me what dose to take?

No, and it will not. Veya records what you enter. Decisions about your treatment belong to you and the prescriber who looks after it, and the patient information supplied with your medicine is the place to look for how it should be taken.

How is Bydureon different from Byetta?

Same active substance, exenatide, but Bydureon is prolonged-release and taken once weekly, where Byetta is immediate-release and taken twice a day around meals. Check which one your packaging names.

What happens to my entries if I stop paying?

CSV export works in normal use and after cancelling. Your record is exportable as a file you keep, rather than something that becomes unreadable when a subscription ends.

Does Veya work if I inject on a different day some weeks?

Yes. You record the date you actually injected. Nothing assumes a fixed day, and a week that moved is simply a week that moved.

Is Veya connected to AstraZeneca?

No. Veya is provider-neutral and independent. It does not sell, supply or prescribe medication, and it is not affiliated with any manufacturer. Bydureon is named here to identify the medicine this page is about.

Can I log which presentation I use, the vial kit or the pen?

Yes. You can note whichever you were given in the entry itself; Veya does not distinguish between them beyond what you choose to record.

Can I get my history out to show someone?

Yes. Entries export as a CSV file, which opens in a spreadsheet and prints. Several people find it easier to hand over a printed sheet than to pass a phone across a desk.
