How can I manage my chronic white fungal nail infection?

Question

Hello doctor,

I need your advice regarding a long‑term nail infection. I have had a white fungal infection on one fingernail for more than one year. The nail color has completely changed; it is becoming thick and lifted from the nail bed. There is also swelling, redness, pain, and sometimes warmth around the nail.

When I press the nail, it hurts a lot. The appearance has not improved with previous treatments. I used Fluconazole weekly and Ketoconazole cream for around two months, but there was no improvement.

Currently, I have been recommended to start:

Terbinafine 250 mg daily.
Ciclopirox 8% nail lacquer (topical).

My concern is about safety. My hemoglobin is 9.5, so I want to ask:

Is it safe for me to take Terbinafine 250 mg daily with this Hb level?
Will Terbinafine cause any serious side effects to my liver or overall health?
Is it okay to use Ciclopirox 8% daily along with Terbinafine?
Do I need any blood tests (like LFTs) before starting the medicine?
Is this the correct treatment for my chronic nail fungus?

Please guide me about the safest and most effective treatment for my condition.

Thank you.

Hello,

Welcome to icliniq.com.

I understand your concern.

Chronic nail infections can be very frustrating. Thank you for sharing the pictures (attachments removed to protect the patient’s identity) for a clearer idea. Based on your description and the nail images, yes, this appears to be onychomycosis, a fungal nail infection.

Regarding your questions, let us go step by step:

Terbinafine and anemia: Terbinafine does not usually worsen anemia, so a low hemoglobin level alone is not a contraindication. It can cause elevations in liver enzymes, usually mild, but rarely serious liver injury. Before starting Terbinafine, you should check your liver function tests and hepatitis B and C profile. If these are normal, you can use it safely.
Using Ciclopirox with Terbinafine: Yes, it is safe to use Ciclopirox 8% nail lacquer along with Terbinafine. This combination is often used when medications like Fluconazole or Itraconazole cannot be given, such as during pregnancy.
Which antifungal to choose: Normally, Itraconazole pulse therapy (seven days each month, then a three-week break) is considered first-line treatment for nail fungus. Terbinafine or Fluconazole are alternatives.

Whichever option you choose, it is important to continue treatment for at least five to six months, as toenails take that long to grow. Two months is not enough time to see visible results.

From my perspective, I recommend stopping all medications, both oral and topical, for three to five days to avoid interference. Then get a nail culture and sensitivity test from a reputable laboratory. This will identify the exact fungal species.

After the report, you can choose the most appropriate medication. This is the best and internationally accepted approach. Instead of choosing medications randomly, the culture will confirm whether it is a fungus and specify the type: dermatophyte, Candida, or another organism. The test requires only a tiny, painless clipping from the nail surface. Meanwhile, keep your feet and toes dry.

I hope this helps with your query.

Thank you.
