Description:

A rigid casting material made of gypsum (plaster) impregnated on a gauze bandage. When wet, it hardens to form a supportive cast or splint for immobilizing fractures, sprains, or post-surgical limbs.

Prescription:

• No, it is an over-the-counter (OTC) medical supply/device, not a drug. Often applied by healthcare professionals.

Therapeutic Category:

• Orthopedic casting material; Fracture immobilization aid; Medical device for musculoskeletal support.

Active Ingredients/Composition:

• Calcium sulfate hemihydrate (gypsum plaster) on cotton or synthetic gauze. No active drug.

Minerals:

• Calcium sulfate (gypsum).

Variant:

• Common widths: 4 inch, 6 inch, 8 inch rolls (or pairs/kits). Also available as pre-cut slabs or kits with padding/under-cast materials.

Consume Type:

• Not consumed; external topical application (wrapped around the limb after wetting).

Directions/Usage:

• Soak the roll in room-temperature water for a few seconds, squeeze excess water, then apply over a padded stockinette or cotton padding in layers. Smooth and hold until it sets (hardens in 5–10 minutes, fully sets in ~30 minutes). Usually applied by a doctor, nurse, or orthopedic technician. Keep dry after setting.

Common Side Effects:

• Rare with proper use. Possible skin irritation, pressure sores, or allergic reaction to padding/material if left on too long or applied too tightly. Cast may cause itching or odor if wet or worn for weeks.

Package Type:

• Sealed plastic pouch or box containing one or more rolls (often sold in pairs for larger sizes). Kits may include padding, stockinette, and bandages.

Storage Advice:

• Store in a cool, dry place away from moisture (plaster reacts with water and hardens if exposed). Keep sealed in original packaging.

Safety Advice:

• Must be applied by trained personnel to avoid tight casts that cut off circulation.
• Never get the finished cast wet. Check for swelling, numbness, tingling, or discoloration — seek immediate medical help if present.
• Do not remove or tamper with the cast yourself.
• Not for open wounds or infected areas without medical supervision.
• Keep out of reach of children (small parts risk).
