Treating infected skin depends on severity — minor wounds respond to cleaning and bandaging at home, while fever or red streaks require medical attention.
For the full breakdown, see our best Cream For Infected Skin guide.
When deciding how to treat infected skin, the first step is gauging severity. Minor wounds with localized redness and mild swelling can often be managed at home with proper cleaning and bandaging, healing within a few days. But if you develop fever, chills, red streaks spreading from the wound, or swelling larger than half an inch, medical care is required — antibiotics or a minor drainage procedure may be necessary, and delaying care can allow infection to spread to deeper tissue.
How to Clean and Bandage a Minor Infection at Home
For small cuts and scrapes with mild redness, start by cleaning the area with running water and mild soap around the wound — avoid soap directly in the open cut as it can cause irritation. Stop bleeding with gentle pressure using a clean cloth or sterile gauze. Remove debris with tweezers cleaned beforehand with rubbing alcohol. Apply a thin layer of antibiotic ointment or petroleum jelly to keep the wound moist and discourage bacterial growth, then cover with a clean adhesive bandage. Change the bandage daily; if redness spreads rather than fades over 48 hours, medical attention is needed.
Apply a warm compress for 10–15 minutes three to four times a day to increase blood circulation, bringing immune cells to fight infection and reduce swelling. Keep the wound dry between compresses and change the bandage if wet or soiled. Some redness immediately around a cut is normal, but if the red area grows larger or feels hot, that signals spreading infection and requires a doctor’s evaluation.
These support healing when used alongside proper cleaning and bandaging. The Mayo Clinic’s first aid guidance for cuts confirms this approach: clean the wound, apply antibiotic ointment or petroleum jelly, cover with a sterile bandage, and watch for signs of infection.
When Should You See a Doctor for an Infected Wound?
Seek prompt medical care for any of these signs:
- Fever or chills
- Red streaks extending from the wound toward your body
- The infected area is larger than half an inch across
- No improvement after 48 to 72 hours of home care
- Increasing pain, warmth, or swelling around the wound
- Pus that continues draining or spreads beyond the original wound
Do not drain or squeeze the infection at home. Poking or pressing an abscess pushes bacteria deeper into surrounding tissue. When you see a doctor, they will examine the area and check vital signs. For abscesses, they may perform incision and drainage under local anesthesia. For cellulitis or systemic symptoms, they will prescribe oral antibiotics and may order blood tests for sepsis. Follow all instructions and return if symptoms do not improve within 48 hours of starting treatment.
| Sign or Symptom | Home Care OK | See Doctor |
|---|---|---|
| Small cut with mild redness | Yes | No |
| Red streaks from wound | No | Yes |
| Fever or chills | No | Yes |
| Infection larger than 0.5 in. | No | Yes |
| No improvement in 2–3 days | No | Yes |
| Increasing pain or swelling | No | Yes |
| Pus that spreads or worsens | No | Yes |
For pus-filled abscesses, incision and drainage is standard — the doctor numbs the area, makes a small cut, and drains the pus. For non-purulent infections like cellulitis, oral antibiotics are primary. Finish the full course even if you feel better — stopping early can allow the infection to return stronger and with antibiotic resistance.
For recurrent cellulitis, the CDC advises checking for tinea pedis (athlete’s foot) as a hidden cause. Severe infections with high fever, rapid spreading, or confusion require hospitalization for intravenous antibiotics and close monitoring.
FAQs
Can I use hydrogen peroxide on an infected wound?
No — hydrogen peroxide damages healthy tissue and slows healing. Clean with running water and mild soap, then apply antibiotic ointment or petroleum jelly and cover with a bandage.
How long does a minor skin infection take to heal at home?
With proper care, minor infections typically improve within 48 to 72 hours. If redness or swelling does not reduce in that time — or worsens — see a doctor.
Is it safe to pop or drain an abscess at home?
No. Squeezing or lancing an abscess forces bacteria deeper and can cause a more serious infection. A doctor should perform incision and drainage in a sterile setting if needed.
