Antibiotics for skin cuts

A clinician may consider antibiotics when a cut is infected or has features that make infection more concerning. Medicine does not replace removal of dirt, closure when appropriate, drainage of pus, or assessment for damage beneath the skin.

Mild tenderness and a narrow pink edge can occur early in healing. Infection is more concerning when redness spreads beyond the wound, pain or swelling increases, the area becomes hot, pus appears, or fever develops.

Risk also depends on how the injury happened. Deep punctures, crush injuries, retained dirt or glass, and human or animal bites need professional assessment. Reduced immunity, diabetes, and poor circulation can make wound problems harder to control.

Apply steady pressure with clean material to control bleeding. Rinse the cut with clean running water, gently clean the surrounding skin, remove only loose surface debris, and cover it with a sterile non-stick dressing. Replace a wet or dirty dressing.

Do not put leftover antibiotic tablets or another person's cream on the wound. If an antibiotic is prescribed, use it as directed and report significant side effects. Ask whether your tetanus protection needs updating, especially after a dirty or puncture wound.

Seek urgent care if bleeding does not stop with firm pressure, the wound is gaping or deep, fat or another deeper structure is visible, sensation or movement is reduced, or an object remains embedded. Prompt review is also needed for a bite, a heavily contaminated injury, or spreading redness, pus, fever, red streaks, or worsening pain.

Call emergency services for severe bleeding, faintness, confusion, or signs of a serious allergic reaction after medicine, including breathing difficulty or swelling of the mouth or throat.

Clarify whether the cut needs closure, deeper cleaning, imaging for a foreign object, a tetanus vaccination, or antibiotic treatment. Ask how often to change the dressing and which visible changes should bring you back.
