Temazepam (CAS 846-50-4): storage and disposal
Temazepam is a Schedule 3, Class C benzodiazepine that pharmacies and clinics hold as tablets for short term sleep problems. As a substance it is harmful if swallowed. Its controlled status rather than its chemistry decides how it is handled, and most surplus stock is a mix of date expired packs and returned patient medicines. Keeping those items locked, identified and properly recorded matters more than anything visible on the tablet.

Harmful or irritant
This chemical is a manual enquiry
This is a controlled drug. Controlled drugs have their own legal requirements, which depend on the schedule and can cover storage, witnessing and destruction, so they cannot be priced through a standard form.
UK Misuse of Drugs Regulations 2001: Schedule 3, Class C.
It cannot be priced through a form. Please do not open or move it. Call us or send an enquiry and we will talk through the next step, which depends on what it is. Keep following your own procedures for controlled drugs, radioactive materials, gases and asbestos.
What to do this week
- Leave it where it is. If it looks old, crystalline or damaged, do not open or move it and keep people away from the shelf. If there is immediate danger, such as a leak, fumes or a fire, leave the area and call 999.
- Write down the label wording, the rough age and where it is stored, from a safe distance.
- Send us those details, and a photo if you can take one without touching it.
Safe storage in a school or lab
Live dispensing stock is what it must be kept apart from once it is surplus, because a date expired pack back in circulation is the mistake that matters. Inside the locked controlled drugs arrangement, give expired and returned tablets their own marked shelf or box, and keep the register or stock record current for them. Patient returns are especially worth separating, as a bag of mixed medicines may hide a strip or two among ordinary stock. Keep the location dry and the packs in their original cartons, so that batch numbers and dates stay readable. A clinic with a small holding should ask the responsible pharmacist or accountable officer to confirm the arrangement.
How to tell it has deteriorated
Tablets of this kind age quietly, and few visible signs appear before the printed date passes. A chalky surface, crumbling, caking in a loose container, or a colour change after damp would all be reasons to stop trusting a pack. Blisters may split at the foil, and returned packs often lose their outer carton, which takes the batch and expiry details with it. Unidentified tablets in a returned pot are the commonest problem. Comparing their look against a known pack is no proof of what they are, so they should be recorded as unidentified. Beyond that, the printed date and the record are the reliable guide.
How it is disposed of
This does not go through our standard collection route. It is arranged by manual enquiry, and never goes down the drain or into general waste.
Surplus stock leaves a site by the route that the accountable officer or responsible pharmacist decides, under the Misuse of Drugs Regulations 2001. A general chemical collection does not cover its destruction, so it is not quoted online. Routine Schedule 3 stock destruction does not normally need an authorised witness, although local procedures or particular circumstances may ask for one. Send a manual enquiry instead, and a store assessment is recommended. In a healthcare setting 18 01 09 would normally be the code. Separate the count into date expired stock and patient returns, and give the strengths and pack sizes, because reconciling those against the record is the slow part. Leave everything in its locked place until advised, and do not tip tablets into a bin or sink to tidy the shelf.

The code depends on where the waste came from and what it contains, and classifying it is the producer's duty. Use the waste code finder to see why.

Questions
A care home has sent back loose tablets with other medicines. How do we list them?
Record them as you received them, keep them in the locked arrangement and ask the responsible pharmacist to confirm the identity if possible. Do not sort or count them more than your procedure needs. In your enquiry, describe them as patient returns from a care home.
Do Schedule 3 tablets need the same locked storage as our Schedule 2 stock?
For this drug, keep to the existing locked controlled drugs arrangement that you already have. Your responsible pharmacist or accountable officer decides the detail of records for each schedule, and that should be written into your procedure rather than worked out at the cabinet.
Can we return unopened stock in date to a wholesaler instead of disposing of it?
That is a question for your responsible pharmacist and the wholesaler, as it is a supply matter rather than a waste one. Anything that cannot go back stays locked and recorded until it is cleared, and an enquiry can then cover what is left.
