TERBIKEM 250MG

# TERBINAFINE 250 MG ## SHORT DESCRIPTION **Terbinafine 250 mg** is an oral antifungal medicine used to treat certain **fungal infections**, particularly fungal infections of the nails (**onychomycosis**) and some fungal infections of the skin when oral treatment is appropriate. Terbinafine belongs to the **allylamine class of antifungal medicines**. It works by interfering with fungal cell-membrane formation, ultimately causing the fungal cells to die. > **Important:** Oral terbinafine can rarely cause serious liver injury. Liver health and potential drug interactions should be considered before and during treatment as clinically appropriate. --- # KEY BENEFITS * Provides systemic antifungal treatment. * Commonly used for **fungal nail infections**. * May be prescribed for certain fungal skin infections when oral treatment is appropriate. * Has activity against many **dermatophyte fungi**. * Accumulates in keratin-rich tissues such as the skin and nails. * Convenient **once-daily 250 mg** dosing is commonly used in adults for several indications. --- # USES / INDICATIONS Terbinafine 250 mg tablets may be prescribed for: ### Fungal Nail Infections * Onychomycosis caused by susceptible dermatophytes. * Fungal infections affecting fingernails or toenails. ### Certain Fungal Skin Infections Depending on the clinical diagnosis, oral terbinafine may be used for: * Tinea corporis (ringworm of the body) * Tinea cruris (jock itch) * Tinea pedis (athlete's foot) The exact indication and duration depend on the type and severity of infection. > Oral terbinafine is **not effective against every type of fungal infection**. A healthcare professional should confirm the diagnosis before treatment. --- # HOW IT WORKS Terbinafine inhibits an enzyme called **squalene epoxidase**, which is important for fungal cell-membrane synthesis. This causes: 1. Reduced production of **ergosterol**, an essential component of the fungal cell membrane. 2. Accumulation of **squalene** inside fungal cells. 3. Disruption of the fungal cell membrane. 4. Ultimately, **death of susceptible fungal cells**. **Terbinafine → inhibits squalene epoxidase → decreases ergosterol + increases squalene → damages fungal cells → antifungal effect.** --- # DOSAGE & ADMINISTRATION > **Take Terbinafine 250 mg exactly as prescribed by your healthcare professional.** ### Usual Adult Dose For many approved indications, the commonly used oral dose is: **250 mg once daily.** However, the appropriate dose and duration depend on the infection, patient characteristics, liver function, and local prescribing guidance. ### Typical Treatment Duration Treatment duration varies considerably: * **Fingernail fungal infection:** often around 6 weeks * **Toenail fungal infection:** often around 12 weeks * **Skin fungal infections:** may require shorter courses Some severe or slow-growing nail infections may require longer treatment. ### How to Take * Swallow the tablet with water. * Take it at approximately the same time each day. * It can generally be taken **with or without food**. * Complete the prescribed course unless your healthcare professional tells you to stop. ### Missed Dose Take the missed dose when remembered unless it is nearly time for the next scheduled dose. **Do not take two doses together.** ### Important for Nail Infections Even after the fungus has been eliminated, an affected nail may continue to look abnormal until healthy nail grows out. This can take **several months**. --- # SIDE EFFECTS ## Common Side Effects Possible side effects include: * Headache * Nausea * Diarrhea * Indigestion * Abdominal discomfort * Feeling bloated * Rash * Itching * Muscle or joint aches * Tiredness Taste or smell disturbances can occur and, in some patients, may persist after treatment. ## Serious Side Effects Stop taking the medicine and seek medical advice promptly if you develop symptoms that may indicate **liver problems**, such as: * Persistent nausea * Loss of appetite * Unusual tiredness * Upper abdominal pain * Dark urine * Pale or clay-colored stools * Yellowing of the skin or eyes Other serious reactions can include: * Severe skin rash or blistering * Facial or throat swelling * Difficulty breathing * Severe allergic reaction * Unexplained bruising or bleeding * Persistent fever or sore throat Seek urgent medical attention for severe or rapidly worsening symptoms. --- # PRECAUTIONS & WARNINGS ## Liver Disease Oral terbinafine can cause serious liver injury, although this is uncommon.
