Nail fungus (onychomycosis) is a common infection that can affect your toenails and fingernails. It can cause your nails to become discolored, thick, and even crumbly, highlighting the importance of treatment with products like Kerasal Nail Repair.
One topical treatment option for nail fungus is undecylenic acid. Undecylenic acid is an antifungal agent that can be used to treat fungal infections of the skin and nails.
This article will provide you with an overview of how to use nail fungus undecylenic acid treatments, what to look for, and what to expect.
What is undecylenic acid?
Undecylenic acid is a fatty acid that comes from castor oil. It’s a natural ingredient that helps stop fungus from growing.
You can find undecylenic acid in several forms, including liquids and creams. You can buy products containing this ingredient over the counter under different brand names, such as Fungi-Nail, ProClearz, Forces of Nature Nail Fungus, and others.
Because you don’t need a prescription, undecylenic acid is easy to access and use at home.
Uses of Undecylenic Acid for Nail Fungus
Undecylenic acid is primarily used to treat fungal infections of the skin and nails (onychomycosis), similar to products like FungiCURE Anti-Fungal Liquid. It’s effective because it targets dermatophytes, which are a common cause of nail fungus.
To use it, you simply apply the solution to the affected nail and a small amount of the surrounding skin. Keep in mind that undecylenic acid is best for mild to moderate cases of nail fungus.
For severe or deeply embedded infections, it may not be effective on its own. In those cases, it’s often used with other antifungal treatments to get the job done.
How to use undecylenic acid liquid
If you and your doctor decide that undecylenic acid is the right treatment for your nail fungus, here’s how to use it.
Preparation
Before you start, clean and dry the area of the infected nail and surrounding skin thoroughly. You may want to soak the area in warm water to soften the nail.
Then, use a nail file to thin any thickened areas of the nail.
Application
Apply a thin layer of the liquid to the affected nail and the surrounding skin. Use the applicator that comes with the product, or use a clean cotton swab. Be sure to wash your hands well afterward.
Frequency and duration
Apply the medication twice a day, or as directed by your doctor. Keep using it for as long as your doctor says, even if your symptoms seem to be getting better. You may need to use the medicine for several weeks or months.
Important considerations
Don’t bandage or cover the area you’re treating.
Avoid getting the medication in your eyes, nose, mouth, or vagina.
Side effects, precautions, and interactions
Like any medication, undecylenic acid may cause side effects. Before using it, be sure to take a minute to learn the possible risks and how to use it safely.
Possible side effects
The most common side effects of undecylenic acid are mild skin irritation, burning, or redness. If the irritation is severe, stop using the medication.
Allergic reactions are rare but serious. Get immediate medical help if you develop a rash, itching, swelling, dizziness, or difficulty breathing.
Precautions
Talk to your doctor before using undecylenic acid if you’re pregnant, breastfeeding, or have any underlying health conditions. Keep this and all medicines out of the reach of children.
Drug interactions
Tell your doctor about all the medicines you take, including prescription, over-the-counter, and herbal supplements. Even though undecylenic acid is absorbed minimally into the body, it’s still important to consider any possible interactions.
Frequently Asked Questions
What do podiatrists prescribe for toenail fungus?
Podiatrists often prescribe oral antifungal medications like terbinafine or itraconazole for toenail fungus. They might also recommend topical treatments, including prescription-strength antifungals or medicated nail lacquers, alongside professional debridement of the infected nail.
What are the negative effects of undecylenic acid?
Undecylenic acid is generally considered safe for topical use, but potential side effects can include mild skin irritation, redness, burning, or itching at the application site. Allergic reactions are rare but possible. It’s always a good idea to do a patch test before widespread use.
Is undecylenic acid better than tolnaftate?
Undecylenic acid and tolnaftate are both topical antifungals, but they work differently. Undecylenic acid is a fatty acid with antifungal properties, while tolnaftate is a synthetic antifungal agent. Which one is “better” depends on the individual and the severity of the infection. Some studies suggest undecylenic acid may be more effective against certain types of fungi.
Why does it take so long to cure toenail fungus?
Toenail fungus takes a long time to cure because toenails grow very slowly. Antifungal medications need to reach the nail bed to eradicate the infection, and this can take several months, even with consistent treatment. The thickness of the nail also makes it difficult for topical medications to penetrate effectively.
Does undecylenic acid cure toenail fungus?
Undecylenic acid can be effective in treating mild to moderate cases of toenail fungus. However, it may not be as effective for severe infections, which might require stronger prescription medications. Consistency is key, and it’s important to follow the product instructions carefully. It can take several months to see noticeable improvement.
The Bottom Line
Undecylenic acid is a potentially useful treatment for mild nail fungus, but it’s important to keep your expectations realistic. See a doctor or other healthcare professional for a diagnosis and to discuss treatment options. If you do use undecylenic acid, be sure to apply it consistently and for as long as your doctor recommends for the best results.
