Square Sedil & Diazepam
Sedil is a Square Pharmaceuticals medicine containing diazepam, an active ingredient belonging to the benzodiazepine class of medicines.
Square's official product information identifies Sedil tablets as containing Diazepam BP 5mg. Our dedicated product page provides information about Sedil 5mg diazepam tablets.
Important Information About Diazepam
Manufacturer reputation and medicine suitability are separate issues. A recognised pharmaceutical manufacturer does not mean diazepam is appropriate for every patient.
Diazepam Requires Appropriate Medical Assessment
Diazepam is a prescription-only medicine in the UK. It can cause drowsiness, dependence and withdrawal, and combining it with alcohol, opioids or other sedating medicines can increase the risk of serious harm. Follow advice from your prescriber and the patient information supplied with the medicine.
People, Technology and Controlled Production
Pharmaceutical manufacturing depends on trained personnel, controlled environments, suitable equipment and documented quality systems working together.
Square describes its manufacturing and quality operations as incorporating production technology, quality-control laboratories and structured pharmaceutical processes.
These systems are intended to support consistency from incoming materials through manufacturing, packaging and finished-product quality checks.
- Controlled manufacturing environments
- Trained pharmaceutical personnel
- Manufacturing and laboratory technology
- Quality-control procedures
- Finished-product quality checks

Packaging Alone Does Not Confirm Genuine Sedil
A medicine box, blister strip or tablet that looks genuine should not automatically be treated as proof of authenticity.
Counterfeit medicines may copy established pharmaceutical branding and packaging. Appropriate sourcing, traceability, manufacturer details, batch information and professional pharmacy checks are more meaningful than visual appearance alone.
- Check the medicine name and active ingredient
- Check the labelled strength
- Check manufacturer details
- Check batch and expiry information
- Read the supplied patient information
- Ask a pharmacist if anything appears unusual
