Toe Nail Fungus

Sep 23, 2014

By Trevor Shewfelt, Pharmacist at the Dauphin Clinic Pharmacy

The Watson Arts center put on their Beer and Cash fund raiser a couple weeks ago. The beer from Half Pints Brewery in Winnipeg was to die for. The food from Doug Morley was divine. But the Johnny Cashs we have in Dauphin stole the show. It amazes me how much talent we have here in the Parkland. I think my favorite Johnny Cash song isnt one of his originals. I think I like his cover of Nine Inch Nails, Hurt the best.

If you really did have nine inch long toe nails, fungus might be a problem for you. Toe nails are specialized parts of the skin that protect the ends of our digits. The nail grows out from the small area inside the white half moon by the cuticle. It is estimated that 6.5% of Canadians have toe nail fungus. It is more common in older people. It is estimated that over 30% of people between the ages of 60 and 70 have toenail fungus. People with nail problems like having a nail injury or psoriasis near the nail are more likely to get toe nail fungus. Also people who wear footwear that don't let the feet breathe, people with poor circulation to their feet, people with diabetes and people with compromised immune systems are more likely to get fungus. The medical term for toe nail fungus is onychomycosis. Onchomycosis is caused mainly by dermatophytes.

You can get infected toenails through contact with an infected person or through contact with an infected surface like a bathroom floor where the fungus is present. It is common to get toenail fungus at the same time as you get athletes foot.

Fungus infected toenails look weird, but are not itchy or painful. In the most common type of toe nail infection, the end and/or sides of the nail get thicken and yellow. The infection can spread in all the way up to the cuticle and the nail matrix. Crumbling yellow debris is usually seen under the nail edge. We think of toenail fungus as just being ugly to look at. However, there are some non-cosmetic problems that can result from a fungal infection. The nail fungus can spread to other nails or even other parts of the body like the groin or scalp. In diabetics, the thickening nail can add extra pressure to the toes and lead to ulcers or sores. In extreme cases with diabetics, sores on the feet can lead to amputation, but that is rare.

What can be done if you have toenail fungus? First you should have a doctor have a look at the nail. There are other things besides fungus that can cause nail problems. Once a definite diagnosis has been made, you and your doctor need to decide how you want it treated. In some cases, the infected part of the nail can be removed. Onychomyconsis can also be treated with medication. There are both oral pills and topical medications to apply to the nail.

The two most common oral medications for toenail fungus are terbinafine (lamisil) and itraconazole (sporanox). It is difficult to say which medications work the best because the studies about toenail fungus are very small and not that well done. The studies usually talk about when the nail is fungus free. A patient has to remember that even after the nail is fungus free, it will still take months and months for the nail to grow out and the yellow, thick, discolored areas to disappear. Toe nails can take a year to grow back.

Terbinafine has to be taken every day for 3 months to cure toenail fungus. Like all antifungals it can cause liver damage but the chances are remote. Your doctor should test your liver function before you go on it and repeat the liver function test in about 6 weeks. Depending on where I looked, I saw cure rates with terbinafine at about 46%.

Itraconazole is another antifungal oral medication, but it can be given as pulse therapy. That means you take the pills everyday for a week and then take 3 weeks off. You repeat this for 3 months. This pulse therapy can be more convenient for many people. Again there is the risk of liver damage and you doctor should check you out. The cure rates for itraconazole I found were around 23%.

If you arent sure you want to get your liver function checked or have your toenail removed there are other options. Ciclopirox (Penlac) looks like nail polish. You apply it everyday and wipe off any excess about once a week with nail polish remover. Again, it will need to be used for about 3 months. The cure rate I found was about 7%.

There is a new prescription toe nail fungus nail polish on the market. It is called Efinaconazole (Jublia). Its cure rate is listed at 17%.

The Dauphin Clinic Pharmacy makes another anti-fungal nail polish. For better or worse several of the doctors have dubbed it Trevors Magic Nail Polish. It is made with the anti-fungal fluconazole. There are no large clinical studies on it, so I have no cure rate to give you, but anecdotally some patients who used it found it worked well. The big advantage of the fluconazole nail polish we compound over the commercial one is coverage. If you go over your pharmacare deductible our compounded nail polish is covered while the commercial one is not.

Which ever nail fungus treatment you choose there are some things you can do on you own to help your toenails. Keep your nails short, dry, and clean. Keep your feet dry make sure your feet (including between your toes) are completely dry before putting on shoes and socks. Wear absorbent cotton socks , and change them at least once a day. Wear proper fitting shoes and rotate shoes to allow them to dry out between uses. Dont go barefoot in damp public places like public showers wear shower shoes. People with nail fungus shouldn't share shoes, socks or nail clippers with others. If you have diabetes, make sure your blood sugar is under control. As mentioned we dont want people with diabetes having their toe nail fungus causing sores and ulcers.

You could have it allMy Empire of Dirt. I will let you down. I will make you hurt. Johnny Cashs cover is better than the Nine Inch Nails original. Nine Inch nails wont help your foot health either. So dry those feet and trim those toe nails. Dont let toe nail fungus make you hurt. Look after your feet and your feet will look after you.
