Almost 4,000 pharmacy-compounded animal medicines recalled in the US: what's wrong and how to use these medicines safely

What happened

Wedgewood Pharmacy, a US pharmacy that makes custom medicines for animals, is voluntarily recalling almost 4,000 of its products. US veterinary media reported this on 23 October 2026. The recall covers medicines the pharmacy shipped nationwide between 18 February and 6 October 2026: oral products, injections, eye and topical products.

Why they are being recalled

According to the company, discrepancies in laboratory testing data may have affected the strength of the products. This means they could contain too much or too little active ingredient. The company received 98 complaints, 7 of which it considers serious, but it has not given details.

The recall is voluntary: the company is withdrawing the products itself, without waiting for the authorities to require it. This is normal practice when a manufacturer cannot guarantee quality. The scale of the recall suggests the problem probably lay in the quality control system rather than in a single bad batch: products shipped over almost eight months are under suspicion.

What compounded medicines for animals are

Most medicines are made by manufacturers in standard forms and strengths, and they go through authorisation by regulators. But sometimes a standard medicine isn't suitable for an animal. The vet then writes a prescription, and a specialist pharmacy prepares the medicine individually. This is known as compounding.

Compounded medicines don't go through the checks that authorised medicines do, so their quality depends entirely on the pharmacy. Authorisation means the manufacturer has proven a medicine's quality, safety and effectiveness to a regulator, and every batch is tested according to approved rules. A compounded medicine has no such checks: the pharmacy prepares it to a prescription and is itself responsible for its accuracy. Wedgewood is one of the largest veterinary compounding pharmacies in the US, so the recall has affected a great many practices and owners.

Why they are needed

Compounded medicines solve real problems:

• cats and tablets. Many cats refuse tablets, so the pharmacy turns the medicine into a tasty liquid, a treat or a gel that is rubbed into the skin of the ear;
• small animals. A tiny dog, a rabbit or a bird needs a dose that isn't available in ready-made tablets;
• discontinued medicines. Some products stop being made, but animals still need them;
• combining several medicines in one form to make treatment simpler;
• horses and exotic pets, for which ready-made forms often don't exist.

For example, cats with an overactive thyroid are often prescribed their medicine as a gel that is rubbed onto the inside of the ear. This is convenient for owners and doesn't stress the cat, but absorption through the skin varies, so the vet must always check that treatment is working with blood tests.

Why the wrong strength is dangerous

For many medicines a small dosing error doesn't matter. But for some, the gap between a therapeutic dose and a dangerous one is narrow — for example, anti-seizure medicines for dogs, thyroid medicines for cats and heart medicines. If they contain too little active ingredient, the disease gets out of control: seizures return and heart function worsens. If they contain too much, signs of overdose appear: lethargy, vomiting, wobbliness, a racing heart.

So a strength error is particularly dangerous for animals on long-term medication, taken for months or years. In a dog on anti-seizure medicine it may show as seizures returning or, on the contrary, as heavy sleepiness and an unsteady gait. In a cat on thyroid medicine, as weight loss and restlessness if the dose is too low, or lethargy and vomiting if it is too high.

What owners in the US should do

The company and veterinary media advise:

• check whether your animal received Wedgewood products during the period — the batch number and pharmacy name are on the packaging;
• if a product is covered by the recall, stop using it but don't throw it away, and contact your vet and the company's recall service straight away to arrange a replacement;
• tell your vet if you noticed unusual behaviour or a worsening of the condition during treatment.

Importantly, don't stop treatment on your own — especially anti-seizure or heart medicines — without talking to your vet. Stopping some medicines suddenly can cause a serious deterioration. Call your vet the same day: they will tell you how to switch medicines without a gap. Keep any packaging you have: it may be needed to check the batch and work out what went wrong.

How medicine recalls work

A recall is a routine safety mechanism: if a manufacturer or pharmacy finds a quality problem, the products are withdrawn and buyers are warned. In the US, the FDA classifies recalls by level of risk: from the most serious, where a product could cause serious harm, to those where harm is unlikely. Recall information is published on the FDA website, and practices and pharmacies are notified directly.

Owners most often hear about a recall from their vet or pharmacy, who are required to inform clients. But it's best not to rely only on a phone call: if your animal is on long-term medication, it's worth checking recall news from time to time — in the US on the FDA website, in the UK with the Veterinary Medicines Directorate, and in the EU with national medicines agencies.

What veterinary practices should do

Veterinary practices and pharmacies are being asked to check their stock using the company's online lookup, set aside recalled products, contact Wedgewood, identify clients who received these medicines and warn them. Many practices will have to phone hundreds of owners, so if you know you received these products, don't wait for the call — get in touch yourself. For practices it is also a reminder of how important accurate records are: which product, from which pharmacy and which batch each patient received.

What this means for the UK and Europe

Wedgewood operates in the US, and owners in the UK and Europe are not directly affected by this recall. But compounded medicines exist here too. Under the EU veterinary medicines regulation, and under the UK's own rules, a vet must first prescribe medicines authorised for that species and that condition. If no such medicine exists, they can follow a special procedure known as the "cascade" to use another authorised medicine or prescribe one that a pharmacy prepares individually.

Large veterinary compounding pharmacies shipping thousands of products nationwide are less common in Europe than in the US, but custom medicines for cats and exotic pets are made here too. So the safety rules this US recall highlights are useful for owners here as well. In the UK and Europe, compounded medicines for animals are usually prepared by a pharmacy to a specific vet's prescription and are subject to the standards for pharmacy preparation. If you have doubts about the quality of such a medicine, ask the pharmacy how and when it was made and how to store it, and tell your vet about any unusual reaction in your animal — reports like these help problems to be spotted sooner.

How to use compounded medicines safely

• Ask your vet why a compounded medicine is needed and whether there is an authorised alternative.
• Get medicines from the pharmacy your vet recommends.
• Check the label: your animal's name, the name and strength of the medicine, the dose and the expiry date.
• Store the medicine as directed: many liquid and gel forms need to be kept in the fridge and used within a short time.
• If a new supply looks different — a different colour, smell or consistency — check with the pharmacy before giving it to your animal.
• For animals on long-term treatment, have the monitoring tests your vet recommends done regularly: for example, thyroid hormone levels in cats or blood levels of anti-seizure medicine in dogs.

When to see a vet urgently

Contact your vet immediately if, after starting a new bottle or batch of medicine, your animal's seizures return or become more frequent, or it shows lethargy, vomiting, wobbliness, refusal to eat, a fast or slow heartbeat or breathing difficulties. Take the medicine's packaging with you — the batch number will help get to the bottom of things quickly. If your vet isn't available, go to an out-of-hours clinic. Don't wait until morning if your animal is having seizures.

What happens next

The company is continuing to investigate the causes and handle enquiries from practices and owners. US regulators keep a close eye on the quality of compounded veterinary medicines, and this recall is likely to prompt further inspections. For owners anywhere, the main lesson is simple: a compounded medicine is convenient but more vulnerable to error, and its effects need to be watched especially closely. If your animal is on such medicines, agree a schedule of check-ups and blood tests with your vet and keep a note of how your animal is doing — a diary like this really helps you notice when a medicine starts working differently.
