Veterinary medicine wholesale dealer's authorisation (WDA)
How to legally run a business that deals with the wholesale of animal medicines (veterinary medicinal products) (formerly VMGN 8) and the WDA Register.
The Veterinary Medicines Directorate (VMD) is responsible for inspecting and authorising veterinary wholesale dealers.
You can only wholesale an animal medicine if you have one of the following:
a marketing authorisation
a manufacturer’s authorisation
a wholesale dealer’s authorisation (WDA)
You also need a WDA if you’re a ‘virtual wholesaler’, ie you buy and sell an animal medicine but contract out the handling of the medicine to another authorised wholesale dealer.
When you need a WDA
You must obtain a WDA to sell or supply medicines to anyone other than the end user.
You don’t need a wholesale dealer licence if you’re a broker. A broker is someone who has arranged for a retailer to buy animal medicines directly from a wholesale dealer at a reduced rate.
Apply for a WDA
Complete the application form for WDA (MS Word Document, 72.2KB) and send to the VMD.
If you need to apply for a variation to your WDA, submit the variation application form for WDA (MS Word Document, 66.7KB)
Inspections Administration Team
Your site will be inspected before the VMD grant your application. This inspection should take place within 90 days of your application being validated.
You can’t start wholesale dealing before you get confirmation in writing that your authorisation has been granted.
You need to pay a fee for the application of your WDA and for your initial site inspection.
You’ll also have ongoing annual and inspection fees.
The application and annual fees are not refundable or transferable.
You should qualify for a fee reduction if your annual turnover is less than £35,000 or you only deal in any of the following:
medicines classified as Authorised Veterinary Medicines-General Sales List (AVM-GSL)
products covered by the exemption for small pet animals
We aim to process applications within 10 working days of receipt.
Once you get your authorisation, you’ll have regular inspections.
Inspections are risk based depending on compliance with GMP at the last inspection and the type of veterinary medicines handled.
You must make your site available for inspection and provide any information or samples requested.
Validity of authorisation
Your authorisation is valid indefinitely subject to satisfactory inspections. However, your will be revoked if you don’t deal in veterinary medicines for 5 years.
Variation to an authorisation
You must notify the VMD before making any significant change to your premises, facilities or operations.
You need to complete a variation application form for WDA (MS Word Document, 66.7KB) and send it to the VMD’s inspection administrations team to change an existing authorisation.
Your authorisation could be suspended, revoked or changed by force if you make alterations before your change has been approved.
You must have a signed requisition form (signed in ink) to sell any controlled drugs listed in schedule 2 or 3 of the Misuse of Drugs Regulations 2001.
For further information see the Controlled drugs: Veterinary medicines page.
You must use a contract if you want to pass any storage and distribution to another wholesale dealer. The contract must state where the division of responsibilities lies.
You must also do all of the following to meet the conditions of your authorisation:
get animal medicines only from authorised manufacturers or wholesale dealers
supply animal medicines only to people who are legally allowed to have them, eg retailers who are authorised to supply veterinary medicines to end users
only supply animal medicines covered by your wholesale dealer’s authorisation
list all your distribution activities in your authorisation
store animal medicines in line with storage and transport conditions
make sure you have proper stock rotation and carry out a stock audit at least once a year
have an emergency recall plan (a system in place that if a recall of the product is required then the company is readily able to identify and contact all their customers)
have technically competent staff (who are trained in all of the company procedures and understand he principles of GDP)
set up and maintain a quality system (a system detailing your quality and distribution procedures)
Your wholesale dealing premises must be all of the following:
secure and lockable
free from contamination
capable of storing animal medicines under the required storage conditions
You’re breaking the law if you don’t meet these conditions, and could face prosecution or lose your authorisation.
WDA Qualified Person
You must choose someone to be your wholesale dealer qualified person, (WQP), and register their details with the VMD.
This is someone who is responsible for making sure you’re meeting the conditions of your authorisation. They should regularly check all areas and your quality system, and keep records of the checks they do.
This person doesn’t have to be a pharmacist, but they should know about the conditions of your authorisation and the medicines you distribute.
If they’re not a pharmacist, they should have at least a year’s experience in either of the following:
handling, storing and distributing medicines
selling or getting medicines
They should also have at least a year’s experience in managing the wholesale distribution of medicines on a similar scale.
You don’t have to employ this person, but they must be available at all times.
You must keep records of all sales for at least 5 years and have them available for inspection. Your records should include all of the following:
- date and nature of the sale
- type of animal medicine
- manufacturer’s batch number
- expiry date
- name and address of the supplier or recipient
Storage and transport conditions
You must make sure that proper storage conditions are always maintained, including during transportation, for all medicines including those that:
need to be stored at low temperatures (known as cold chain products)
should be stored below 25º or 30º C (known as temperate chain products)
You should record temperatures at low and high levels – this includes in contained storage areas within warehouses, eg flammable stores.
You need to continuously record the temperature if you’re storing medicines either in small refrigerators or in warehouses.
If you’re storing medicines in large warehouses you should use temperature mapping (noting the changes in temperature in a single space caused by things like doors opening).
You should repeat temperature mapping every 2 to 3 years and after any major change to the premises, stock layout, or heating system.
You should fit temperature alarms to large and walk-in units and those smaller units used to store products at risk from freezing. Alarms should be checked for correct functioning at the designated set temperatures at least annually.
Transport temperature: cold-chain goods
You should label the storage requirements of any medicines that need to be stored at low temperatures.
You can use insulated containers to transport small volumes of cold-chain goods. You must make sure that products which are damaged by freezing don’t come into direct contact with ice packs at subzero temperatures.
You can ship larger volumes of cold-chain goods in refrigerated transport. You need to use recording probes or individual temperature monitoring devices to monitor temperatures to protect products at risk from freezing.
You need to review the temperature records for each shipment and have in place a procedure for corrective action if anything goes wrong.
Temperature system checks
You need to use measuring and recording devices in critical areas, eg temperature monitoring of storage and transport facilities for cold chain goods at risk from freezing.
Your measurements should be checked against a traceable reference device (i.e the temperature must be calibrated) at least once a year. Your records should show the temperature before and after.
