What Happens If I Run Out of Medication?

If you have just realised that your dog or cat has run out of medication, it can be worrying. Many pet owners discover the problem when they miss a dose or notice the last tablet has already been used.

For pets with long-term health conditions, medications are often given daily to keep symptoms under control. Missing doses can sometimes allow symptoms to return or worsen.

If you are wondering what to do if your pet runs out of medication, the most important step is to act quickly. In many cases there are safe ways to arrange a repeat prescription for your pet or obtain further medication without interrupting treatment.

Contact Your Veterinary Practice First

If your pet’s medication was originally prescribed by your veterinary practice, contacting them should usually be the first step.

Many practices are able to authorise repeat prescriptions for pets receiving long-term treatment, provided your pet remains under their care and within the required monitoring period.

Your vet may be able to:

• Authorise a repeat prescription
• Dispense a short supply directly from the practice
• Issue a written prescription so you can order medication from an online veterinary pharmacy

Some medications require periodic health checks before further prescriptions can be issued, particularly where monitoring or reassessment is needed.

If Your Pet Needs Medication Urgently

In some situations, running out of medication may lead to a worsening of your pet’s condition.

Certain medicines are used to control serious medical problems and should ideally be given consistently. Missing doses may result in symptoms returning or worsening.

Examples include medications used to manage:

• Heart disease, such as pimobendan (Vetmedin)
• Epilepsy and seizure disorders, such as phenobarbital
• Allergic skin disease treated with medications such as Apoquel
• Hormonal conditions treated with medications such as levothyroxine (Thyforon)

If your pet becomes unwell after missing medication, or if the medication is essential for controlling their condition, you should contact your veterinary practice or their out-of-hours emergency service for advice.

An out-of-hours veterinary provider can assess your pet and provide treatment if emergency care is required.

Contact Your Online Veterinary Pharmacy

If you normally order medication from an online veterinary pharmacy, contacting them early can sometimes help prevent treatment gaps.

Once a valid veterinary prescription has been received and approved, pharmacies may be able to prioritise the dispatch of medications used to manage important long-term health conditions.

Where possible, this may help ensure medicines used for conditions such as heart disease, epilepsy or endocrine disorders are supplied as quickly as possible.

Common Reasons Pets Run Out of Medication

Veterinary practices and pharmacies are often contacted by owners who suddenly realise their pet’s medication has run out. This usually happens during long-term treatment where medication needs to be given regularly.

Some of the most common situations include:

• A repeat prescription has expired and needs to be renewed
• A reminder to reorder medication was missed
• The dosage was increased and the medication ran out sooner than expected
• A delivery delay occurred while waiting for a new prescription to be approved
• The final tablets or capsules were used earlier than planned

If you notice your pet’s medication supply running low, contacting your veterinary practice or pharmacy early usually allows treatment to continue without interruption.

Plan Ahead for Repeat Medication

The easiest way to avoid running out of medication is to plan ahead and reorder before your current supply finishes.

Many veterinary pharmacies offer reminder systems that help owners keep track of when repeat medication is due.

At Vetalia, owners can set a free medication reminder during checkout. This sends an automated email reminder when it is time to reorder medication.

The reminder service is optional and simply sends an email prompt before your pet’s medication runs out. It does not create a subscription and no payments are taken automatically.

Many owners choose to set their reminder 1–2 weeks before their pet’s medication is due to run out, which allows enough time for prescription approval, ordering from wholesalers and delivery.

When to Seek Immediate Veterinary Care

If your pet has missed medication and begins showing new or worsening symptoms, you should contact your veterinary practice immediately.

Signs that may require urgent veterinary attention include:

• Collapse or severe weakness
• Difficulty breathing
• Seizures
• Severe lethargy
• Sudden worsening of an existing medical condition
