Formula Information

A small arrow pointing down

Terbinafine 50 mg/ml Oral Liquid is a custom-prepared medication designed to treat fungal infections by inhibiting the growth of fungi. This antifungal agent is particularly effective against a variety of dermatophytes and yeasts that are commonly responsible for skin, nail, and hair infections. The liquid formulation ensures that patients who have difficulty swallowing pills, such as children and the elderly, can still receive effective treatment. It is also beneficial for those with impaired gastrointestinal function where absorption of the drug might be a concern with solid dosage forms.

The active ingredient, terbinafine, works by interfering with the fungal cell membrane's sterol biosynthesis, leading to the death of the fungal cell. This action is primarily fungicidal, meaning it actively kills the fungi, rather than just inhibiting its growth. Terbinafine is well-absorbed and can be taken with or without food, providing flexibility for patients. The oral liquid form allows for precise dosing, which is critical for achieving the desired therapeutic effect while minimizing potential side effects.

Terbinafine 50 mg/ml Oral Liquid is commonly prescribed for the treatment of onychomycosis (fungal nail infections), tinea pedis (athlete's foot), tinea cruris (jock itch), and tinea corporis (ringworm of the body). It is also used in scalp infections and other conditions as determined by a healthcare provider. The duration of treatment varies depending on the location and severity of the infection, with nail infections typically requiring a longer course of therapy.

Patients and prescribers should be aware that while terbinafine is a well-tolerated medication, it can have side effects, and its use should be monitored by a healthcare professional. Liver function tests may be recommended before and during treatment, as terbinafine has been associated with liver enzyme abnormalities and, in rare cases, more serious liver damage. Other potential side effects include gastrointestinal disturbances, skin reactions, and taste disturbances.

Drug Interactions

A small arrow pointing down

Terbinafine is an antifungal medication that works by inhibiting the enzyme squalene epoxidase, which is a key component in the fungal cell membrane synthesis pathway. This action leads to a deficiency in ergosterol, an essential component of fungal cell membranes, and results in fungal cell death. Terbinafine is commonly used to treat various fungal infections, including onychomycosis (fungal infection of the nails), tinea pedis (athlete's foot), tinea cruris (jock itch), and tinea corporis (ringworm).

When considering the use of terbinafine 50 mg/ml oral liquid, it is important to be aware of potential drug interactions that may affect the efficacy of the medication or increase the risk of adverse effects. Terbinafine is metabolized primarily through the liver by the cytochrome P450 enzyme CYP2D6, and drugs that affect this enzyme can lead to altered levels of terbinafine. For example, CYP2D6 inhibitors such as fluoxetine, paroxetine, and quinidine may increase terbinafine levels, potentially leading to toxicity. Conversely, inducers of CYP2D6, such as rifampin and carbamazepine, may decrease terbinafine levels and reduce its effectiveness.

Terbinafine can also affect the metabolism of other drugs. It may decrease the clearance of drugs metabolized by CYP2D6, such as tricyclic antidepressants, beta-blockers, selective serotonin reuptake inhibitors (SSRIs), and monoamine oxidase inhibitors (MAOIs), potentially leading to increased plasma concentrations and risk of adverse effects. Additionally, terbinafine may increase the levels of caffeine and theophylline, necessitating monitoring and possible dose adjustments of these agents.

Patients taking terbinafine should also be cautioned about the potential for increased risk of bleeding when combined with anticoagulants such as warfarin, as terbinafine can potentiate the effects of warfarin. Close monitoring of prothrombin time or international normalized ratio (INR) is recommended in patients receiving both medications.

It is also important to note that terbinafine may interact with oral contraceptives, leading to irregular menstrual cycles or breakthrough bleeding. Patients should be advised to report any changes in their menstrual cycle to their healthcare provider.

Alcohol consumption should be minimized or avoided during terbinafine therapy, as concurrent use may increase the risk of hepatotoxicity. Patients should be advised to report any symptoms of liver dysfunction, such as jaundice, dark urine, or persistent nausea and vomiting.

Given the potential for significant drug interactions, it is crucial for patients and prescribers to review all current medications, including over-the-counter drugs and herbal supplements, before initiating treatment with terbinafine oral liquid. Adjustments to therapy or additional monitoring may be necessary to ensure safe and effective use of this medication.

If you have any questions or require further information regarding drug interactions with terbinafine 50 mg/ml oral liquid, please do not hesitate to reach out to us at Bayview Pharmacy. Our team of compounding pharmacists is dedicated to providing comprehensive support to ensure the safe and effective use of our formulations.

How Does it Work

A small arrow pointing down

Terbinafine is an antifungal medication that works by inhibiting the enzyme squalene epoxidase, which is found on the fungal cell membrane. This enzyme is essential for the synthesis of ergosterol, a key component of fungal cell membranes. By disrupting the production of ergosterol, terbinafine compromises the structural integrity of the fungal cell membrane, leading to cell death and ultimately the resolution of the fungal infection. The 50 mg/ml oral liquid formulation of terbinafine provides a precise concentration that allows for accurate dosing, which is particularly important in achieving the desired therapeutic effect while minimizing potential side effects.

The terbinafine oral liquid is particularly beneficial for patients who have difficulty swallowing pills, such as children and the elderly, or for those who may have conditions that affect their ability to swallow solid dosage forms. The liquid formulation allows for flexible dosing, which can be adjusted according to the patient's weight, the severity of the infection, and the specific type of fungal infection being treated. This formulation is used to treat a variety of fungal infections, including onychomycosis (fungal infection of the nails), tinea pedis (athlete's foot), tinea cruris (jock itch), and tinea corporis (ringworm of the body). It is important to note that the duration of treatment with terbinafine oral liquid can vary depending on the location and severity of the infection, and it may take several weeks to see complete resolution of symptoms.

For patients and prescribers considering the use of terbinafine 50 mg/ml oral liquid, it is essential to adhere to the prescribed dosing regimen and to complete the full course of therapy, even if symptoms improve before the medication is finished, to ensure the infection is fully eradicated and to prevent resistance. As with any medication, there may be potential side effects, and it is important to monitor for any adverse reactions. If you have any questions about the terbinafine oral liquid formulation or its use in treating fungal infections, please reach out to us at Bayview Pharmacy. Our team of compounding pharmacists is here to provide guidance and support to ensure the safe and effective use of this medication.

Other Uses

A small arrow pointing down

Terbinafine is primarily known for its antifungal properties, specifically for the treatment of fungal infections such as onychomycosis (fungal infection of the nails), tinea pedis (athlete's foot), tinea cruris (jock itch), and tinea corporis (ringworm of the body). However, the versatility of a 50 mg/ml terbinafine oral liquid formulation extends its potential utility beyond these common disease states.

In addition to the aforementioned conditions, terbinafine oral liquid may be beneficial in treating other types of fungal infections that require systemic antifungal therapy. For instance, it can be considered for scalp ringworm (tinea capitis), particularly in situations where topical treatment is impractical or has failed. Furthermore, terbinafine has been used for certain cases of systemic mycoses – such as histoplasmosis and sporotrichosis – although these are less common indications and should be managed under the guidance of an infectious disease specialist or a dermatologist with experience in treating complex fungal infections.

Moreover, the oral liquid formulation of terbinafine presents advantages for patients who have difficulty swallowing pills, such as those with esophageal disorders or dysphagia. It is also a suitable choice for pediatric and geriatric populations who may find liquid formulations easier to ingest. Additionally, the liquid form allows for flexible dosing adjustments, which can be particularly beneficial in pediatric dosing where weight-based calculations are required.

While terbinafine is generally well-tolerated, prescribers and patients should be aware of potential drug interactions and side effects. For instance, terbinafine can interact with certain medications such as antidepressants, beta-blockers, and other antifungal drugs. Therefore, thorough medication reconciliation should be performed to minimize the risk of adverse interactions.

Patient counseling is crucial for the successful use of terbinafine oral liquid. Patients should be instructed on proper storage, dosing, and duration of therapy. It is important to complete the full course of therapy, even if symptoms improve, to effectively clear the infection and reduce the risk of resistance. The liquid formulation should be shaken well before use and measured with an appropriate dosing device to ensure accuracy.
