When is oral antifungal treatment recommended for nail fungus?

Nail fungus can thicken, split, discolour, or loosen a nail. A clinician may recommend a tablet when the infection reaches deeper nail structures or affects several parts of the nail, because topical medicine may not reach the affected area well. The diagnosis should be checked before treatment because injury, psoriasis, and other nail disorders can look similar. A nail sample or examination may help guide the choice of medicine.

Arrange a dermatology assessment to confirm the infection and review your medical history, current medicines, liver health, pregnancy status, and alcohol use. Take the medicine exactly as prescribed if it is selected; do not share tablets or use leftover treatment. Keep nails short and dry, avoid picking under the nail, and treat athlete’s foot if present so it does not continue to seed the nail. Improvement is gradual because a healthy nail must grow out.

Seek prompt medical care for spreading redness, warmth, swelling, pus, severe pain, fever, or a rapidly changing dark area around a nail. Contact the prescriber promptly if you develop yellowing of the eyes or skin, unusually dark urine, severe nausea, marked tiredness, or a widespread rash while taking an antifungal tablet.

Ask whether the nail appearance has been confirmed as fungus, whether a sample is needed, which treatment suits your health history, what monitoring is required, and how to recognise medicine side effects.
