Adhesive bandages (plasters)
Adhesive bandages, commonly known as plasters or band-aids, are essential medical devices used to protect minor wounds, cuts, and abrasions. These self-adhesive strips combine a sterile pad with an adhesive backing to keep wounds clean and promote healing. Available in various sizes and materials, adhesive bandages are a fundamental component of first aid kits worldwide.
Purpose and Medical Uses
Adhesive bandages serve multiple important functions in wound care and medical treatment. Their primary purposes include:
- Protecting minor cuts, scrapes, and abrasions from dirt, bacteria, and external contamination
- Absorbing small amounts of blood and wound fluid
- Keeping wounds moist to promote faster healing
- Preventing scab disruption and reducing scarring
- Providing cushioning against friction and pressure
- Covering blisters to prevent rupture and infection
- Securing small gauze pads over wounds
- Protecting surgical incisions during initial healing
Common Usage Settings: Homes, schools, workplaces, sports facilities, healthcare centers, hospitals, and outdoor activities where minor injuries may occur.

How to Use Adhesive Bandages: Step-by-Step Guide
Step 1: Assess the Wound
Check the injury size and severity. Adhesive bandages are suitable only for minor cuts, scrapes, and wounds. Deep cuts, puncture wounds, or wounds with heavy bleeding require medical attention.
Step 2: Clean Your Hands
Wash hands thoroughly with soap and water for at least 20 seconds. Dry hands completely before touching the wound or bandage.
Step 3: Clean the Wound
Rinse the wound gently with clean running water. Remove visible dirt or debris. Pat dry with a clean cloth or sterile gauze. Apply antiseptic solution if recommended.
Step 4: Select Appropriate Bandage
Choose a bandage size that extends at least 1 cm beyond the wound edges on all sides. Select the type based on wound location and activity level.
Step 5: Open Package Carefully
Open the bandage package from the tear notch. Avoid touching the sterile pad in the center. Handle only the adhesive portions.
Step 6: Remove Protective Layers
Peel away the protective backing from one side of the bandage. Do not touch the pad or adhesive surface.
Step 7: Apply to Wound
Center the pad directly over the clean, dry wound. Press the adhesive firmly onto surrounding skin. Remove the second protective layer and press down the other side.
Step 8: Secure and Smooth
Press around all edges to ensure good adhesion. Smooth out any wrinkles or air bubbles. The bandage should lie flat against the skin.
Step 9: Check Fit
Ensure the bandage is comfortable and not too tight. It should allow normal movement without restricting circulation.
When to Change: Replace the bandage daily, when it becomes wet, dirty, or loose, or if the wound shows signs of infection.
Precautions and Safety Considerations
General Precautions
- Never apply bandages to deep wounds, severe burns, or injuries with bone or tendon exposure
- Do not use on infected wounds without medical consultation
- Avoid applying bandages too tightly as this can restrict blood flow
- Check expiration dates before use - expired bandages may lose sterility
- Do not reuse adhesive bandages under any circumstances
- Remove bandages if severe skin irritation, redness, or rash develops
- Ensure wounds are dry before application for proper adhesion
- Never share bandages between individuals
Warning Signs - Seek Medical Attention If:
- Wound shows increased redness, swelling, warmth, or pus
- Pain worsens instead of improving
- Red streaks appear extending from the wound
- Fever develops after injury
- Wound edges separate or gap open
- Bleeding does not stop with pressure
- Signs of allergic reaction appear (severe itching, hives, difficulty breathing)
Allergy Considerations
Some individuals may experience allergic reactions to adhesive components, latex, or other bandage materials. Signs include excessive itching, redness beyond the adhesive area, blistering, or rash. Use hypoallergenic or sensitive skin varieties if allergies are suspected. Test a small area first if there is a history of skin sensitivity.
Age-Specific Safety
- For infants and toddlers: Use under supervision to prevent choking hazard if removed and placed in mouth
- Select smaller sizes appropriate for tiny fingers and limbs
- Choose colorful or character designs to make application easier for young children
- Monitor for signs of discomfort or skin irritation
- For elderly individuals: Use gentle removal techniques to prevent skin tears on fragile skin
Proper Storage and Maintenance
Storage Guidelines
- Store in a cool, dry place away from direct sunlight and heat
- Keep in original packaging until ready to use
- Maintain storage temperature between 15-25 degrees Celsius
- Avoid humid environments like bathrooms for long-term storage
- Keep out of reach of young children
- Store in easily accessible location for emergency use
- Organize by size and type for quick selection
Stock Management
- Check expiration dates regularly, typically 3-5 years from manufacture
- Rotate stock using oldest bandages first
- Discard any packages that are torn, damaged, or compromised
- Maintain adequate supply of various sizes and types
- Replace bandages in first aid kits after use
- Keep inventory list in first aid kits for schools and workplaces
Safe Removal
To remove adhesive bandages safely, gently pull parallel to the skin rather than upward. Remove slowly to minimize discomfort and prevent skin damage. For stubborn bandages, apply warm water or oil to loosen adhesive. Always remove in the direction of hair growth when possible.
Frequently Asked Questions
How long can an adhesive bandage stay on?
Generally 24 hours maximum. Replace daily or sooner if wet, dirty, or loose. Some waterproof types can stay on for up to 3-5 days if they remain clean and intact.
Should wounds be covered or left open to air?
Minor wounds heal faster when kept moist and covered with bandages. Open air healing is a myth for most minor wounds. Keep covered for first few days, then reassess.
Can adhesive bandages be used on wet skin?
No. Skin must be completely dry for proper adhesion. Moisture prevents bandages from sticking properly and can trap bacteria against the wound.
Are waterproof bandages really waterproof?
Water-resistant bandages repel water during brief exposure like handwashing or showering. They are not designed for prolonged submersion like swimming. Check specific product claims.
What if the adhesive causes skin irritation?
Remove immediately and clean the area. Switch to hypoallergenic or sensitive skin bandages. If irritation persists or worsens, consult a healthcare provider.
Can bandages be cut to fit smaller wounds?
Not recommended. Cutting compromises sterility of the pad. Use properly sized bandages instead. Only the adhesive edges can be trimmed if necessary.
Do antibacterial bandages prevent infection better?
Proper wound cleaning is more important than antibacterial bandages. These may offer additional protection but cannot replace good hygiene and wound care practices.
How tight should a bandage be applied?
Secure but not tight. Should not restrict movement, cause throbbing, or leave marks. If fingers or toes turn pale, cold, or numb, the bandage is too tight.
Can adhesive bandages be used on animal bites?
Animal bites require immediate medical evaluation due to infection risk. Do not cover with bandages until examined by healthcare provider.
What is the white or clear fluid under the bandage?
Clear or light yellow fluid is normal wound drainage (serous fluid). This is part of healing. Thick, cloudy, or colored discharge may indicate infection requiring medical attention.
Can bandages be applied over antibiotic ointment?
Yes. Apply a thin layer of ointment as directed, then cover with bandage. Some bandages already contain antibiotic agents, so check before adding additional ointment.
Are fabric bandages better than plastic ones?
Both have advantages. Fabric bandages are breathable and flexible for joints. Plastic bandages are waterproof and transparent for wound monitoring. Choose based on need and location.
Additional Important Information
Environmental Considerations
Most adhesive bandages are single-use disposable items. Dispose of used bandages in regular waste bins wrapped in tissue or paper. Do not flush down toilets. Some manufacturers now offer biodegradable or eco-friendly options made from bamboo, organic cotton, or plant-based materials.
