Fungal infections are common, and they can affect any part of your body. You can get a fungal infection on your skin, even in your nails, which can be treated with options like ciclopirox nail lacquer, or even on your scalp. These infections can be more than just uncomfortable — they can itch, they can hurt, and they can make you feel self-conscious about the way your skin looks.
One of the most common and effective medications used to treat fungal infections is terbinafine. You can take terbinafine as a pill, or you can apply it directly to your skin as a cream, gel, spray, or solution.
This article takes a close look at using terbinafine on your skin. We’ll cover what you should know before you start using it, what to expect while you’re using it, and what kind of results you can hope for. We’ll also talk about precautions you should take and potential side effects.
Read on to learn more about terbinafine before and after skin treatment.
What is terbinafine?
Terbinafine is a prescription antifungal medication.
It works by targeting ergosterol, a key part of fungal cell membranes. Without ergosterol, the fungus can’t survive, and the infection starts to clear.
You can only get terbinafine with a prescription from a healthcare professional.
Brand names
You may have heard of terbinafine under the brand names Lamisil and Terbinex. But you can also get it as a generic medication.
Dosage forms
Terbinafine comes in a few different forms:
- Oral tablets
- Topical cream
- Topical gel
- Topical spray
- Topical solution
Before using terbinafine: Important considerations
When you’re ready to start terbinafine, it’s important to have all the information you need to be safe and get the best possible outcome.
Allergies and Sensitivities
Be sure to tell your doctor about any allergies you have, especially if you’re allergic to terbinafine or other medications. Allergic reactions can range from a mild skin rash to a very serious reaction called anaphylaxis.
Medical History
Tell your doctor about any health conditions you have, especially:
- Liver disease: People with liver disease should only use terbinafine with great caution, if at all.
- Blood disorders: If you have a blood disorder, lupus, or a weakened immune system, your doctor will need to monitor you carefully while you take terbinafine.
Drug Interactions
Tell your doctor about all the medicines you take, even over-the-counter medications and herbal supplements. Terbinafine can change the way some medications work, and some medications can change how terbinafine works.
Some examples of medicines that can interact with terbinafine are amphetamine and warfarin.
Other Interactions
Check with your doctor about whether you need to avoid certain foods, alcohol, or tobacco while you’re on terbinafine.
Some sources say to avoid caffeine during treatment with terbinafine.
How to use terbinafine
When using terbinafine, follow your doctor’s instructions precisely. The amount of medication you need and how long you’ll use it depend on the kind of infection you have and how severe it is.
Dosage and administration
Here are some general guidelines:
- Oral tablets: You’ll usually take these once a day for two to six weeks, depending on the infection.
- Topical forms: You’ll usually apply these to your skin one or two times a day for one to two weeks.
How to apply topical terbinafine
- Wash and dry the skin that’s affected before you put on the cream, gel, or spray.
- Spread a thin layer of the medication over the affected skin and the healthy skin around it.
- Wash your hands thoroughly after you’ve applied the medication.
- Avoid getting the medication in your eyes, mouth, or on your lips.
How long to use terbinafine
It’s important to complete the full course of treatment, even if your symptoms start to improve. If you stop too soon, the infection could come back.
What to do if you miss a dose
If you forget a dose, take it as soon as you remember. But if it’s almost time for your next dose, skip the missed dose and just take the next one at the regular time. Don’t double up on doses to make up for a missed one.
Terbinafine: Before & After – What to Expect
If your doctor has prescribed terbinafine for a skin infection, you probably want to know when you’ll see some relief. Here’s what you can expect during and after treatment.
Initial Symptoms and Progression
Before you start terbinafine, your skin may be red, itchy, scaly, or cracked. Don’t expect the medication to work overnight. It can take days or even weeks to see a noticeable difference, so be patient and stick with the treatment as your doctor prescribed it.
During Treatment
You may see some worsening of your symptoms at first as the medication starts to do its work. This is usually temporary and should clear up in a few days. For the best results, be sure to use the medication exactly as directed.
After Treatment – Expected Outcomes
With successful treatment, you should see:
- Less redness, itching, and scaling
- Healing of cracks and fissures
- Restoration of a normal skin appearance
Keep an eye on the treated area after you stop using the medication. If you see any signs of the infection coming back, especially concerning symptoms related to toenail fungus healing, contact your doctor.
When to Seek Medical Advice
Get in touch with your doctor if:
- Your symptoms get worse or don’t improve after several weeks of treatment.
- You have concerning side effects, like severe skin reactions or signs of liver problems.
Potential Side Effects and Management
Terbinafine can cause side effects, just like any other medication. Here’s what to watch out for and how to manage them.
Common Side Effects
- Skin reactions: You might see peeling, itching, or a rash. If this happens, avoid clothes that rub or irritate your skin. Instead of scratching, pat the itchy areas. Antihistamines might also help.
- Gastrointestinal issues: Diarrhea, nausea, vomiting, stomach aches, and indigestion are all possible. To manage these, drink plenty of fluids. Stay away from spicy or rich foods, and eat smaller meals. Over-the-counter antacids can also provide some relief.
- Other common side effects: These include headaches, muscle or joint pain, dizziness, and changes in your sense of taste. Rest, drink fluids, and use over-the-counter pain relievers. If you feel dizzy, stop what you’re doing and rest.
Serious Side Effects
These are rare, but it’s important to know about them.
- Liver problems: Watch for yellowing of your eyes or skin, and dark urine. If you notice these signs, get medical help right away.
- Allergic reactions (anaphylaxis): Swelling, trouble breathing, and tightness in your throat are all signs of a severe allergic reaction. Call emergency services immediately.
- Blood disorders: Easy bruising or frequent infections could indicate a blood disorder. Seek medical attention if you experience these symptoms.
Managing Side Effects
In many cases, you can manage side effects on your own with a few simple steps.
- Lifestyle adjustments: Pay attention to your diet, make sure you’re getting enough rest, and stay hydrated.
- Over-the-counter medications: Antihistamines can help with skin reactions, painkillers can ease headaches and muscle pain, and antacids can relieve stomach issues.
If your symptoms are severe or don’t go away, it’s best to talk to your doctor. They can offer further advice and make sure there isn’t a more serious problem.
Frequently Asked Questions
Is terbinafine the strongest antifungal?
Terbinafine is a powerful antifungal medication, but whether it’s “the strongest” depends on the specific fungal infection and individual response. Other antifungals might be more effective in certain situations. Your doctor can determine the most appropriate treatment for your condition.
Why is my antifungal cream not working on my skin?
Several factors could explain why your antifungal cream isn’t working. The infection might be resistant to the medication, the diagnosis could be incorrect, or you may not be applying the cream consistently or correctly. Talk to your doctor to re-evaluate the situation.
How to tell if terbinafine is working on my skin?
You’ll typically see a gradual improvement in your skin condition as terbinafine takes effect. This includes reduced redness, itching, scaling, and thickening. It’s important to continue the treatment for the prescribed duration, even if symptoms improve, to ensure the infection is completely eradicated.
Can I have a glass of wine while taking terbinafine?
It’s generally recommended to avoid alcohol while taking terbinafine, especially oral terbinafine. Both alcohol and terbinafine can affect your liver, so combining them increases the risk of liver damage. Discuss alcohol consumption with your doctor before starting terbinafine.
Is terbinafine good for your skin?
Terbinafine is specifically designed to treat fungal infections of the skin. It’s effective in eliminating the fungus, which can then lead to improved skin health. However, it’s not a general skincare product and should only be used under medical supervision for diagnosed fungal infections.
Closing Thoughts
Terbinafine is a powerful antifungal medication that can be very effective when used the right way. But it’s important to understand that, like all medications, it also comes with potential side effects and requires certain precautions.
Before starting Terbinafine, talk to your doctor or pharmacist. They can give you personalized advice and monitor you for any adverse reactions. Regular check-ups and blood tests may be needed while you’re taking the medication.
For the best results, be sure to follow your doctor’s instructions carefully. Take the prescribed dosage and complete the entire course of treatment, even if your skin starts to look better before you finish the medication. This will help ensure that the fungal infection is completely gone.
