An exenatide tracker is a record of each dose and what followed it, kept in one place whichever cadence you are on. Exenatide is sold as Byetta, injected twice daily around meals, and Bydureon, injected once weekly, and Veya logs either the same way. It records what you enter and nothing else, and it is not a substitute for your prescriber's advice.

Why exenatide users track by the molecule, not the brand

People end up on exenatide through different routes: a brand-name prescription, or a move from one formulation to the other over the course of treatment. This page makes no claim about which route you should be on. What it covers is the record, and the reasons to keep one do not change with the brand on the box.

One molecule, two brands, two completely different cadences

Byetta and Bydureon are both exenatide, but Byetta is immediate-release and injected twice daily around meals, while Bydureon is prolonged-release and injected once weekly. The difference comes from the release profile, not from a different active substance, and it is the single most useful thing to know about this molecule.

Which one you are on matters enormously to what a sensible record looks like, so it is worth naming the brand in your own entries even if you think of the medicine as exenatide.

The two cadences fail in opposite directions

A twice-daily routine is easy to lose count of within a single day: did the evening injection happen, or only the morning one? A weekly routine has the opposite problem: nothing marks the day, so the date itself blurs after a few cycles.

Either way, the fix is the same: a dated entry made at the time, rather than a reconstruction made later.

A symptom needs a date more than it needs a description

Telling a prescriber a symptom 'comes and goes' is much less useful than telling them which day it started, how long it lasted, and which formulation you were on at the time. That detail is exactly what gets lost between the event and the appointment.

A short note made on the day holds up far better than a recollection assembled weeks later.

How Veya tracks your exenatide

  • Dose logThe date and, for the twice-daily formulation, the time of each injection, with the site used, so the pattern is something you can look at rather than something you have to recall.
  • Symptom and side-effect notesWhat you noticed, the day it started, and how long it lasted, sitting on the same timeline as your dose log so the gap between the two is visible.
  • Weight and measurement entriesRecorded when you choose to record them, at whatever interval suits you and your prescriber. Veya stores the numbers you enter and plots them over time.
  • Appointment preparationYour recent entries pulled together into something you can read from or hand over, so the conversation starts from a record instead of a rough recollection.
  • Reminders you setA prompt on whatever schedule you choose, for whatever you have decided to record. Veya reminds you to make an entry; it has no view on your treatment itself.
  • CSV exportYour entries out of the app as a CSV file, in normal use and after cancelling. It is your record, and it should read somewhere other than inside Veya.

What to record across a change in your prescription

Treatment is reviewed and adjusted over time, and some people move between the twice-daily and once-weekly formulations. 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 set out in 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, written down on the day rather than reconstructed later.
  • Which formulation you were on before the change and which you moved to.
  • Any symptom that appeared, disappeared or changed character in the two weeks either side.
  • How long each symptom lasted, which usually tells a prescriber more than how bad it felt.
  • What you had eaten and drunk on a day a digestive symptom was notably worse.
  • The injection site used, 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 your next appointment, written down when they occur to you.

Read from the EMA summaries of product characteristics for Byetta and Bydureon 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.

What's the difference between Byetta and Bydureon?

Same active substance, exenatide, at very different cadences. Byetta is immediate-release and taken twice daily around meals; Bydureon is prolonged-release and taken once weekly.

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.

Can I use one tracker across a change of formulation?

Yes. Entries carry the brand they relate to, so a history that spans a move from twice-daily to weekly stays in one record instead of splitting across two.

Is Veya connected to a pharmaceutical company?

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

Does the tracker handle both a twice-daily and a weekly routine?

Yes. An entry is simply dated and, where relevant, timed. Nothing assumes one cadence over the other, so either formulation fits the same record.

Can I print my history for an appointment?

Yes. Entries export as a CSV file, which opens in a spreadsheet and prints. Handing over a printed sheet is often quicker than passing a phone across a desk.
