What Are MDS Trays?

MDS trays are designed to organise medication by day and time, helping patients take the correct dose at the right time.

They are widely known by several names, including:

• Blister packs / pharmacy-prepared blister packs
• Dosette boxes / dosette trays
• Compliance packs / compliance aids
• Medication trays / pill organisers
• Weekly blister packs / 7-day blister packs

Types of MDS Trays

• 28-Cell MDS Trays (4 Times Daily): Organises medication into four daily doses across seven days. Best for care homes and complex medication regimes.
• 21-Cell MDS Trays (3 Times Daily): Provides three dosing times per day for simpler medication schedules. Best for moderate dispensing needs.
• 7-Day MDS Trays: Offers a clear, structured weekly overview of medication. Best for standard repeat dispensing.

Cold Seal MDS Trays

Designed for use with adhesive sealing systems, allowing for faster preparation without heat.

Heat Seal MDS Trays
