Tinactin vs Lamisil

Listen to the article instead of reading through it.


For individuals dealing with fungal infections of the skin, such as athlete's foot or jock itch, certain topical medications that interfere with the growth of fungi can provide relief and aid in eliminating the infection. Tinactin and Lamisil are two such drugs commonly recommended for these types of conditions. Each one works by inhibiting a different component within the fungus cells to prevent their proliferation.

Tinactin (tolnaftate) is classified as an antifungal agent, which functions by halting the growth of several types of fungi, thereby limiting their spread on your skin. Its primary target is dermatophytes - a group of fungi responsible for many common skin diseases.

Lamisil (terbinafine), on the other hand, also falls under antifungal agents but is more specifically categorised as an allylamine. It operates primarily by disrupting ergosterol synthesis – an essential component for fungal cell membranes; this disruption leads to cell death.

Both medications have proven effective in treating various fungal infections; however, they may vary slightly in terms of application frequency and time required for complete treatment based on their distinct mechanisms.

What is Tinactin?

Tolnaftate (the generic name for Tinactin) was one of the first antifungal agents introduced to effectively treat superficial fungal infections like athlete's foot, ringworm, and jock itch. Approved by the FDA in 1965, Tolnaftate works by inhibiting squalene epoxidase, an essential enzyme for fungal cell wall synthesis. It is applied topically on infected skin areas.

On the other hand, Terbinafine (generic Lamisil), another antifungal agent approved later by the FDA in 1996, not only prevents new fungus growth but also kills existing infections. This gives it a superior edge over Tolnaftate in treating certain conditions such as nail fungus that may require systemic treatment or where topical therapy has failed.

While both are generally well-tolerated with minimal side effects primarily limited to local irritations such as itching or burning at application site; Terbinafine can occasionally cause more severe reactions when taken orally including liver problems and changes in taste sensation. The choice between these two medications largely depends on the type and severity of infection along with patient preferences and tolerance.

What conditions is Tinactin approved to treat?

Tinactin and Lamisil are both approved for the treatment of various fungal infections:

  • Tinea pedis, also known as athlete's foot
  • Tinea cruris, commonly referred to as jock itch
  • Tinea corporis, or ringworm of the body These medications can also be used for other purposes not listed here. Always consult with your healthcare provider for personalized advice.

How does Tinactin help with these illnesses?

Tinactin and Lamisil are both antifungal medications, but they manage fungal infections in different ways. Tinactin (tolnaftate) works by preventing fungi from growing and spreading on the skin surface. It does this by inhibiting the enzymes necessary for the fungus to build its cell membrane, thus making it difficult for the fungus to survive and proliferate. On the other hand, Lamisil (terbinafine) kills fungi directly by causing a deficiency in ergosterol - an essential component of fungal cell membranes - which leads to an increase in cellular permeability resulting in leakage of cellular contents.

Fungal infections can cause skin symptoms like itching, burning, cracking or scaling. Therefore, by halting growth or killing these organisms directly, Tinactin and Lamisil help alleviate these uncomfortable symptoms while also eradicating the underlying infection.

What is Lamisil?

Lamisil, a brand name for terbinafine, is an antifungal medication that prevents fungal growth on the skin. It was first approved by the FDA in 1996. As Lamisil does not belong to the class of azole antifungals like Tinactin (tolnaftate), it has a unique mechanism of action and works by inhibiting an enzyme needed for fungal cell membrane synthesis. This different mechanism means its side-effect profile varies from those of azoles; notably, it may cause liver issues in rare cases and thus is typically reserved for more severe or resistant infections due to these potential risks. Topically applied Lamisil is commonly used for treating certain types of ringworm infections such as athlete's foot and jock itch, especially if initial treatments with typical over-the-counter medications like Tinactin have been unsuccessful.

What conditions is Lamisil approved to treat?

Lamisil is approved for the treatment of several fungal conditions, such as:

  • Athlete's foot (tinea pedis)
  • Jock itch (tinea cruris)
  • Ringworm (tinea corporis)

How does Lamisil help with these illnesses?

Lamisil is an antifungal medication that plays a crucial role in combating infections by disrupting the fungal cell membrane. It works by inhibiting an enzyme, squalene epoxidase, which plays a pivotal part in the production of ergosterol - a key component of fungal cell membranes. Without this substance, the fungus cannot grow and multiply, eventually leading to its death and alleviating symptoms of infection. Much like Tinactin, it's used for treating topical fungal infections including athlete's foot, jock itch and ringworm; however, Lamisil has been shown to provide faster relief from these conditions due to its pharmacological properties. Unlike Tinactin which only prevents growth of new fungi but does not kill existing fungi causing infection on your body, Lamisil acts both as fungicidal (kills fungi) and fungistatic (prevents growth). Therefore patients may prefer using Lamisil over other "typical" antifungal medications such as Tinactin when they do not respond well or need quicker relief.

How effective are both Tinactin and Lamisil?

Tinactin (tolnaftate) and Lamisil (terbinafine) are two common antifungal drugs used in the treatment of athlete's foot, jock itch, and ringworm among other fungal infections. They have both been approved by the FDA for over-the-counter use; Tinactin was first made commercially available in 1965 with Lamisil following closely behind in 1996.

Both tolnaftate and terbinafine act on different stages of a fungus lifecycle thus they may be used under different circumstances. The efficacy of Tinactin and Lamisil has been directly compared in several clinical trials showing similar effectiveness at managing symptoms as well as similar safety profiles. In these studies, all metrics studied to measure efficacy against fungal infection showed no significant difference between patients receiving tolnaftate or those receiving terbinafine.

A review conducted on multiple meta-analysis reports demonstrated that like fluoxetine, Tinactin is effective from the onset of treatment offering relief from itching and burning associated with fungal infection within days. Its side effect profile is favorable compared to many other antifungal medications due to its low systemic absorption limiting potential adverse effects mainly to skin irritation.

On the other hand, a review conducted in 2016 indicated that while terbinafine seems more effective than placebo it appears just as effective when compared with other common antifungals including miconazole nitrate (another commonly prescribed topical antifungal). As such, although it can be considered a first-line therapy option for treating dermatophytic infections there's no clear advantage over using Tolnaftate which also displays high cure rates. Nonetheless, due to its broader spectrum activity encompassing yeast infections alongside dermatophyte fungi some clinicians prefer prescribing Lamisil given this extra coverage.

At what dose is Tinactin typically prescribed?

Topical applications of Tinactin (tolnaftate) are typically applied twice daily, morning and night. It's used for treating conditions like athlete's foot, jock itch, and ringworm. However, Lamisil (terbinafine), another topical treatment option for these fungal infections is generally advised to be used once a day for 7 days. Both should be continued until the infection is fully cleared up which usually happens within several weeks. In either case, if there is no noticeable improvement after one week or symptoms continue beyond the recommended treatment duration, it would be advisable to consult with a healthcare provider. Always follow the usage instructions as indicated on the product packaging or provided by your doctor.

At what dose is Lamisil typically prescribed?

Lamisil treatment is typically started applying a thin layer of cream to the affected area and surrounding skin once daily. After cleaning and thoroughly drying the region, rub in gently. The duration of the treatment depends on your condition but is usually for 1 week for tinea cruris (jock itch) or tinea corporis (ringworm), and for 2 weeks for athlete’s foot. If there's no response or improvement after these periods, you may need further examination by your healthcare provider. Remember that proper hygiene measures should also be taken alongside medication use to prevent re-infection or transmission of fungus.

What are the most common side effects for Tinactin?

Common side effects associated with Tinactin and Lamisil, both of which are antifungal medications, include:

  • Mild skin irritation or itching
  • Burning sensation at the site of application
  • Peeling, scaling or flaking skin
  • Redness or swelling at the site of application

Less commonly experienced but more serious side effects can include severe allergic reactions such as rash, hives, breathing difficulties and dizziness. As always, it is recommended to seek immediate medical assistance if any such adverse effects occur after using these medications.

Are there any potential serious side effects for Lamisil?

While Lamisil is typically safe when used properly, it's important to be aware of potential side effects. Some rare but severe reactions may include:

  • Allergic skin reaction: rash, itching or hives, swelling in the face or lips, difficulty breathing
  • Liver problems: unexplained fatigue, loss of appetite, right upper abdominal discomfort or tenderness, dark urine or yellowing of the eyes and skin (jaundice)
  • Changes in taste and smell which can lead to a decrease in appetite and subsequent weight loss
  • Mood changes like depressive symptoms and anxiety
  • Visual disturbances such as blurred vision

Should any of these side effects occur after initiating treatment with Lamisil, immediate medical attention should be sought.

Contraindications for Tinactin and Lamisil?

Both Tinactin and Lamisil, like most other antifungal medications, may cause skin irritation or a burning sensation in some individuals. If you notice your symptoms worsening, or an increase in redness, itching, or swelling at the application site after using these products, please seek immediate medical attention.

Neither Tinactin nor Lamisil should be used if you have had reactions to allylamines (such as naftifine) or azoles (such as clotrimazole), which are classes of antifungals that include the active ingredients in these products. Always inform your healthcare professional about any allergies when discussing treatment options; previous allergic reactions can indicate potential sensitivity to similar compounds within the same class of drugs.

How much do Tinactin and Lamisil cost?

For the brand name versions of these drugs:

  • The price of a 1 oz. bottle (30 ml) of Lamisil antifungal cream averages around $15, which works out to approximately $0.50/day, depending on your use.
  • The price for a similarly sized container of Tinactin is about $7, working out to roughly $0.23/day.

Hence, if you are using a higher quantity range for Lamisil (i.e., more than once daily), then brand-name Tinactin can be less expensive on a per-day treatment basis. Please note that cost should not be the primary consideration in determining which of these topical antifungals is right for you.

For generic versions of Lamisil (terbinafine) and Tinactin (tolnaftate), costs may be significantly lower:

  • Terbinafine is available at prices starting from as low as $10 for a 1 oz. tube, lowering the daily cost based on usage.
  • Tolnaftate-based creams can start from around $4 for an equal-sized tube.

Remember that effectiveness and personal tolerance should always take precedence when choosing between medications like this; also consult with your healthcare provider prior to making any changes or choices regarding your health care regimen.

Popularity of Tinactin and Lamisil

Tinactin, a brand name for tolnaftate, and Lamisil, which is terbinafine hydrochloride are both popular antifungal medications. They're commonly utilized in the treatment of athlete's foot, jock itch and ringworm.

Tolnaftate (Tinactin) has been used widely for many years with millions of people opting for it due to its promise of relief from uncomfortable fungal infections. In 2020 alone, an estimated 1 million units (including sprays and creams) were sold OTC in the US.

Terbinafine hydrochloride (Lamisil), on the other hand was used by an estimated 2 million people in the USA during that same year. It constitutes a significant portion of antifungal prescriptions given its broad spectrum coverage against various fungi causing skin infections.

Both drugs have held steady market shares over recent years. While Tinactin has been available longer than Lamisil, they both continue to be mainstays in treating superficial fungal conditions owing to their proven efficacy.


Both Tinactin (tolnaftate) and Lamisil (terbinafine) are antifungal medications used in the treatment of various fungal infections, including athlete's foot, jock itch, and ringworm. They function by inhibiting the growth of fungi that cause infection. These two drugs have a long-standing history of usage with numerous clinical studies indicating their efficacy over placebo treatments.

In terms of mechanism of action, Tinactin primarily prevents the growth and spread of fungus while Lamisil kills fungi directly. Given this difference, Tinactin is typically prescribed for minor skin infections due to its preventive nature whereas Lamisil is often recommended when a more aggressive treatment approach is necessary.

Both medications can be found as generics allowing patients to save costs especially those paying out-of-pocket. Consistency in application is key with both these treatments and results may not show immediately due to the time needed for healthy skin to grow back.

As for side effects profiles, both products are generally well-tolerated but potential reactions include itching or irritation at the site of application. It’s crucial for patients using either product to monitor progress closely after starting treatment; if symptoms persist or worsen despite regular use they should seek medical attention promptly.
