Trosyl Nail Solution 283 mg/ml is a topical treatment for nail infections caused by fungi, yeasts and moulds. It contains the active ingredient, tioconazole, which belongs to the broad spectrum of antifungal chemicals called imidazole.
Nail infections, also known as onychomycosis, are caused by certain fungi – most commonly dermatophytes. Dermatophytes need keratin (a fibrous protein found in hair and nails) for growth which is why your nails get affected as well as the surrounding skin. It causes your nails to become discoloured (yellowy-brown), thickened and brittle.
There is a generic version of Trosyl called Tioconazole Medicated Nail Lacquer. They both work in exactly the same way with the same dosage of tioconazole.
How does it work?
The antifungal properties of tioconazole disrupt the cell membranes of fungi and yeasts. Fungi produce ergosterol which makes up a part of their fungal cell membrane. When tioconazole intervenes with the cell membranes, it stops the fungi from producing ergosterol. [1]
For the fungus to survive on the nail, the cell membrane needs to be kept intact – allowing nothing to go in or out. Tioconazole effectively penetrates through the nail into the nail bed, disturbing the cell membranes to kill the fungal cells.
Which antifungal treatment is right for me?
Topical antifungal treatments are usually for mild to moderate onychomycosis. Loceryl Nail Lacquer and Amorolfine Nail Lacquer contain the active ingredient amorolfine and are used for mild infections where the fungus starts at the tip of the nail and spreads below.
Terbinafine (which also goes by the brand name Lamisil) is another option for fungal nail infections that haven’t responded to self-care measures or topical therapy. It’s given as a 250mg tablet and is used for moderate to severe cases. Terbinafine is also sometimes used to treat other fungal infections like athlete’s foot and ringworm. Fungal nail tablets usually work quicker than topical treatments, giving results in 6 weeks to 3 months compared to 6 to 12 months.[2]
It works similar to topical medicines but is stronger as it kills the fungus that causes the infection as it starts to appear. You might want to consider tablets if topical treatments haven’t worked.
Depending on the severity, our clinicians will make sure you have suitable options available to you.

How to use Trosyl Nail Solution
Apply the solution with the brush over the affected nail and surrounding skin
1-2 layers will be enough
Let it dry for 10-15 minutes
Apply every 12 hours
When it dries, it will be slightly greasy. Try to keep water away from the area – if you need to wash up, wear rubber gloves as any soap will remove the film.
Keep using Trosyl until all the infected nail has grown out and new healthy nail tissue is visible.
Are there different strengths of Trosyl?
Trosyl and Tioconazole only come in a dose of 283 mg/ml. There are other antifungals that come in different strengths depending on how severe your infection is.
How long does it take to work?
Having a consistent topical treatment will help you see a positive result in as little as six months. In some cases, it could be up to 12 months
If you apply every 12 hours and leave the film to penetrate through the nail you should see an improvement when the infected part of your nail starts to grow out.
If you don’t see any changes within 6 to 12 months, let your prescriber know as they might suggest another treatment for you.

FAQ: Trosyl
Have something specific you want to know? Search our info below, or ask our experts a question if you can’t find what you’re looking for.
Does Trosyl cause any side effects I should be concerned about?
Answer:
A common side effect of Trosyl Nail Solution is swelling around hands and feet depending on where you’re using it.
Another side effect that may affect 1 in 100 people is a mild rash around the nail. This usually happens during the first week of using Trosyl, but should clear up after that.
If you’re concerned about side effects, let our clinicians know and they can discuss an alternative treatment.
Can I still wear nail polish with Trosyl?
Answer:
No, it is advised not to use cosmetic nail varnish as Trosyl leaves a greasy film that contains the antifungal element needed to pass through the nail to reach the infection. You also need to apply Trosyl twice a day so cosmetic varnish would just block the solution.
Should I cut my nail where the fungus is?
Answer:
If it’s causing you pain, your clinician will advise you if you need to cut the infected nail. You may be referred to a podiatrist or dermatologist as they can professionally do this for you.
Don’t attempt to cut your own infected nail as you might cause more damage. It’s recommended to file down affected areas before applying the solution, and you can do this yourself. Just make sure you use a clean nail file every time, to avoid re-infecting your nail or spreading the infection to other nails.
Do I need a prescription for Trosyl?
Answer:
Trosyl is a prescription medicine for onychomycosis as a clinician needs to check it’s suitable for you before issuing it.
Some nail fungal treatments are available over the counter but these are usually for mild infections or to help prevent further infections.
Can I use Trosyl whilst pregnant?
Answer:
No, you shouldn’t use Trosyl whilst pregnant because you have to use it over a long period of time. There hasn’t been enough research to confirm whether Trosyl Nail Solution is safe to use during pregnancy. [1]
