Impetigo and penicillin

Short answer
Penicillin is not automatically the right treatment for impetigo; antibiotic choice depends on the diagnosis, infection pattern, and medical history.
This answers one question. It is not a diagnosis and does not replace an assessment by a licensed doctor.

Why antibiotic choice varies
Impetigo is a bacterial skin infection, but several details influence treatment: whether sores are localised or widespread, where they are located, how severe they appear, and whether the person has medicine allergies or other health concerns. The clinician may choose a topical medicine or an oral antibiotic rather than penicillin.
A crusted rash is not always impetigo. Crusting Skin is a useful symptom reference, while Atopic dermatitis can cause broken, inflamed skin that may resemble or accompany infection. Examination matters because treating the wrong condition can delay the right care.
What to do about penicillin
Do not start leftover penicillin, share someone else’s medicine, or stop a prescribed antibiotic early without advice. Tell the clinician the exact reaction if penicillin or another antibiotic has caused a problem before; nausea and an allergic reaction are different concerns and should both be reported clearly.
For a small group of sores, the clinician may consider Topical Antibiotic Therapy. When infection is more extensive or topical care is impractical, Antibiotics For Skin Infection may be discussed. Take or apply the selected treatment exactly as instructed and keep the medicine away from children unless prescribed for them.
When to seek urgent help
Contact a clinician if sores spread, pain increases, redness or swelling expands, or there is no expected improvement after treatment begins. Ask for prompt advice before changing antibiotics, especially if an allergy is suspected.
After any antibiotic, seek urgent help for facial or throat swelling, wheezing, trouble breathing, faintness, or widespread blistering. Urgent review is also needed for severe illness, confusion, or marked swelling near the eye.
Questions to bring
Ask whether the rash is definitely impetigo, why a particular antibiotic was selected, and what alternatives exist if you have a penicillin allergy. Clarify the dose or application instructions, missed-dose advice, expected changes, and which reaction requires emergency care.
