A GLP-1 tracker is a record of when you took your medicine and what happened afterwards. Veya keeps both on one timeline, whichever medicine you are on and whether it is injected or swallowed. It records what you enter and nothing else, and it is not a substitute for the advice of your prescriber.

These medicines are not all the same, and a tracker should not pretend they are

Most writing about this class treats it as one thing taken one way. The labels do not. Across the medicines authorised in Europe there are weekly injections, daily injections, a twice-daily injection taken before meals, and tablets swallowed on an empty stomach.

That matters for a record more than the brand name does. What is worth writing down, and how easy it is to forget, follow from the cadence and the form rather than from which box the medicine came in.

Weekly medicines lose the date, daily ones lose the day

A weekly injection has nothing in an ordinary day to anchor it, so after a few cycles the question of whether it was Tuesday or Wednesday stops having an answer you can trust. A daily medicine has the opposite problem: it blends into the background and a missed one passes unnoticed until you count the pen or the blister and the number is wrong.

The fix is the same either way and it is unglamorous. A dated entry made at the time beats a reconstruction made later, and it is the only version that survives six weeks.

A symptom is only useful with a date attached to it

A prescriber can do a great deal with a date and very little with an adjective. Nausea that arrives the evening of an injection and clears two days later is a different observation from nausea that has been constant for a month, and by the time you are in the room describing it the two sound identical.

Recording when something started, how long it lasted, and whether it followed a change is what turns an impression into something a clinician can work with.

People change medicine, and the record has to survive the change

Moving between medicines in this class is common, and it is exactly the moment a record earns its keep. The useful question afterwards is what was different before and after, and that comparison only exists if the record ran continuously through the change rather than starting again on the other side.

A history that spans a switch is worth more than a detailed one that begins the week you noticed a problem.

What Veya records

  • Injections and doses takenThe date of each one, with the site if it was injected. Weekly, daily and twice-daily routines all sit on the same timeline rather than needing different handling.
  • Symptoms and side effectsWhat you noticed, the day it started, and how long it lasted. Entries sit alongside your doses, so the gap between the two is something you can see rather than something you estimate.
  • Weight and measurementsRecorded at whatever interval you and your prescriber find useful. Veya stores the numbers you enter and draws them over time.
  • One record across a change of medicineEntries carry the medicine they relate to, so moving between medicines leaves one continuous history rather than two partial ones.
  • Appointment preparationRecent entries gathered into something you can read out or hand over, so the appointment starts from a record instead of from trying to recall six weeks at once.
  • 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 when your treatment changes

Treatment in this class is reviewed and adjusted, and people move between medicines. 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 medicine you were on before and which you are on now, so the record reads correctly on both sides.
  • Whether the cadence changed, since moving between a weekly and a daily medicine changes the whole shape of the routine.
  • 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.
  • What you had eaten and drunk on a day a digestive symptom was notably worse.
  • The injection site used, if the medicine is injected, 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.

What GLP-1 actually refers to

What the term means
Glucagon-like peptide-1, a hormone the body makes. The medicines are named after the receptor they act on rather than after any one product.
Not a single class
Semaglutide, liraglutide, dulaglutide and exenatide are GLP-1 analogues. Tirzepatide is not: its label describes it as a GIP and GLP-1 receptor agonist, and it sits under a different classification.
Weekly injections
Ozempic and the Wegovy injection (semaglutide), Mounjaro and Zepbound (tirzepatide), Trulicity (dulaglutide), Bydureon (exenatide prolonged-release)
Daily injections
Saxenda and Victoza (liraglutide)
Twice-daily injection
Byetta (exenatide immediate-release), taken before two main meals
Tablets
Rybelsus and Wegovy tablets (semaglutide), taken once daily by mouth

Each line above is read from that product's own EMA summary of product characteristics, sections 1, 2, 4.2 and 5.1, on 11 September 2026. The documents are listed in full below. 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.

Does it work for tablets as well as injections?

Yes. An entry records that you took your medicine and when. The site field is simply not used for a tablet, and nothing else about the record changes.

Are all GLP-1 medicines weekly?

No, and this is the most common thing people get wrong about the class. Several are weekly, two of the liraglutide products are daily, Byetta is twice a day before meals, and Rybelsus and Wegovy tablets are daily by mouth. Which one you are on changes what is worth recording.

I moved from one medicine to another. Do I start a new record?

No. Entries carry the medicine they relate to, so one continuous history spans the change. That is the version worth having, because the useful comparison is across the switch rather than on one side of it.

Is Veya connected to any of these manufacturers?

No. Veya is provider-neutral and independent. It does not sell, supply or prescribe medication, and it is not affiliated with any manufacturer. The medicines are named here only to identify what a record can be kept for.

Do I have to log something every day?

No. Your doses and a note when something is worth noting is a complete record for most people. A tracker that demands daily attention is one you stop using by the third week.

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.
