Xpoterb 1% Dusting Powder

Introduction

Xpoterb is a prescription medication that contains the active ingredient Terbinafine. It is available in the form of a dusting powder and is primarily used to treat fungal infections of the skin.

Uses

Xpoterb is prescribed for the treatment of various fungal infections, including athlete’s foot (tinea pedis), jock itch (tinea cruris), and ringworm (tinea corporis). These infections are caused by certain types of fungi that thrive in warm and moist environments, such as locker rooms, public showers, and swimming pools.

Dosage and Administration

To use Xpoterb, follow these general dosage instructions and methods of administration:

• Clean and dry the affected area before applying the powder.
• Shake the powder onto your hands and gently rub it onto the affected skin.
• Apply the powder once or twice daily, as directed by your healthcare provider.
• Wash your hands thoroughly after applying the powder, unless your hands are the affected area.

Use Xpoterb for the full duration of the prescribed treatment, even if your symptoms improve before the treatment is complete. If you have any questions about the dosage or administration of this medication, consult your healthcare provider.

Mechanism of Action

Xpoterb contains the active ingredient Terbinafine, which belongs to a class of medications called antifungals. Terbinafine works by inhibiting the growth and reproduction of the fungi responsible for the infection. It does this by interfering with the production of a substance called ergosterol, which is an essential component of the fungal cell membrane. By disrupting the integrity of the fungal cell membrane, Terbinafine effectively kills the fungi and helps clear the infection.

Side Effects

Common side effects may include:

• Skin irritation or redness at the application site
• Itching or burning sensation
• Dry skin

If you experience any of these side effects and they persist or worsen, contact your healthcare provider for further guidance.

In rare cases, Xpoterb may cause more serious side effects. If you experience any of the following, seek immediate medical attention:

• Allergic reactions, such as rash, itching, swelling, severe dizziness, or difficulty breathing
• Severe skin reactions, such as blistering, peeling, or a rash that covers a large area of the body
• Liver problems, including yellowing of the skin or eyes, dark urine, or persistent nausea and vomiting

note that this is not a complete list of side effects. If you have any concerns about side effects while using Xpoterb, consult your healthcare provider.

Drug Interactions

Xpoterb may interact with certain medications, vitamins, or herbal supplements. Inform your healthcare provider about all the medications you are currently taking, including over-the-counter drugs and any other treatments you are undergoing.

Some common and serious drug interactions with Xpoterb may include:

• Cimetidine, a medication used to reduce stomach acid, may increase the concentration of Terbinafine in the blood, potentially leading to an increased risk of side effects.
• Certain antidepressants, such as fluoxetine or paroxetine, may also increase the concentration of Terbinafine in the blood.

To ensure your safety and the effectiveness of your treatment, disclose all your medications to your healthcare provider before starting Xpoterb.
