Cat Hyperthyroidism Medication Tracker

Hyperthyroidism in cats is usually managed with daily thyroid medication and regular blood tests to fine-tune the dose. PetHealthLog lets you log each dose, track weight, appetite and energy, and keep one clear timeline between blood tests - so nothing slips and your vet sees the full picture.

Thyroid medication is twice-daily and judged by blood tests

Hyperthyroidism is one of the most common hormonal conditions in older cats, and the usual medication - methimazole - is typically given once or twice every day, often long-term. Skipping doses undermines the whole point, so keeping the schedule matters.

The dose is also adjusted over time based on blood tests, weight and how your cat is doing. A vet getting that right wants an accurate picture: was the medication actually given as prescribed, is the weight recovering, is the appetite settling, is there any vomiting after dosing?

PetHealthLog is free, needs no account and works offline, so logging a dose and a quick note on weight or appetite takes a second and builds into a record your vet can rely on at each recheck.

What the tracker actually does

Common supplies for a hyperthyroid cat (#ad)

Methimazole and any prescription must come from your vet, and the dose is theirs to set. These are common over-the-counter items some owners use around dosing - match anything to your vet's advice.

Frequently asked questions

Is this hyperthyroid cat tracker really free?
Yes. Scheduling thyroid medication, catching missed doses, tracking weight and appetite, side-effect notes, and the PDF report are all free. There is no sign-up and no account, and your cat's records stay on your own device.
Can it handle twice-daily methimazole?
Yes. You can set a medication to be given once or twice a day at specific times and tick off each dose, and a missed dose stays visible - which suits the twice-daily routine many hyperthyroid cats are on.
Why track weight and appetite for a hyperthyroid cat?
Weight, appetite and energy are key signs of how a hyperthyroid cat is responding, so logging them helps you and your vet see whether treatment is settling things and whether the dose still fits. The tracker makes that record easy to keep; interpreting it and adjusting the dose is your vet's job.
Does it work offline?
Yes. PetHealthLog is a progressive web app that works offline, so you can log a dose or a weigh-in without a connection.
Is this a substitute for veterinary advice?
No. PetHealthLog is a record-keeping tool, not veterinary advice. Hyperthyroidism must be diagnosed and managed by a licensed veterinarian, including the medication, dose and blood-test schedule. The tracker simply records what was given and how your cat is doing.
