Understanding Xylocaine NF: What Is It and How It Works?
Xylocaine NF is a specific topical cream containing two active pharmaceutical ingredients: lidocaine and nifedipine. This combination is what makes it particularly effective for treating conditions like anal fissures. Each component plays a distinct role in providing therapeutic benefits.
- Lidocaine (1.5% W/W): A local anesthetic that numbs the affected area by blocking nerve signals that cause pain. This provides immediate relief from the discomfort associated with anal fissures and hemorrhoids.
- Nifedipine (0.3% W/W): A calcium channel blocker that works by relaxing the smooth muscles of the blood vessels around the anus. This action reduces pressure in the anal tissues, improves blood flow, and aids in the healing process of fissures.
The dual action of numbing the pain and relaxing the local musculature is why Xylocaine NF is often prescribed for rectal pain and irritation.
Step-by-Step Guide on How Do You Use Xylocaine NF?
Proper application is critical for the effectiveness and safety of Xylocaine NF cream. Always follow your doctor’s specific instructions regarding the amount and duration of use.
Preparation Before Application
- Clean the area: Wash the affected area with mild soap and warm water. Pat it dry gently with a soft, clean towel.
- Wash your hands: Thoroughly wash your hands with soap and water before and after application to prevent contamination and accidental contact with sensitive areas.
Application for External Relief (Hemorrhoids)
If you are using Xylocaine NF for external hemorrhoids, apply the cream directly to the affected area.
- Apply a thin layer: Squeeze an appropriate amount of cream onto your fingertip as directed by your healthcare provider.
- Cover the area: Gently and evenly spread a thin layer of the cream over the external, affected rectal area.
Application for Internal Relief (Anal Fissures)
For internal use, typically for anal fissures, use the provided rectal applicator.
- Attach the applicator: Screw the rectal applicator onto the opening of the cream tube.
- Insert gently: Insert the applicator slowly into the rectum. Never force it. Insert it to the depth recommended by your doctor.
- Deliver the dose: While squeezing the tube to deliver the prescribed amount of medication, slowly withdraw the applicator.
- Clean the applicator: If the applicator is reusable, clean it thoroughly after each use according to package directions or as advised by your doctor.
Aftercare and Important Reminders
- Wash hands again: Always wash your hands thoroughly after applying the medication.
- Avoid sensitive areas: Take care to avoid getting the cream into your eyes, nose, or mouth. If accidental contact occurs, rinse immediately with cold water.
- Do not use occlusive dressings: Unless specifically instructed by a doctor, do not cover the treated area with airtight bandages or wraps. This can increase absorption and the risk of systemic side effects.
Following Your Doctor's Orders: Amount and Duration
The correct amount and duration of Xylocaine NF use depend on the severity of your condition. It is crucial to adhere strictly to your doctor's recommendations.
- Frequency: Use the cream as often as prescribed by your doctor, usually at specific intervals throughout the day.
- Duration: Treatment for anal fissures may last for a period determined by your medical supervisor, potentially up to several weeks.
- Do not stop abruptly: Do not discontinue use suddenly, as it may cause your condition to worsen.
- No extra applications: If you miss an application, apply it as soon as you remember. However, if it is almost time for the next scheduled application, skip the missed one and continue your regular schedule. Do not apply more than the prescribed amount at any single time.
Potential Side Effects and Precautions
While Xylocaine NF is generally well-tolerated, some side effects and precautions should be noted.
Common Side Effects
- Local irritation, redness, or burning sensation at the application site.
- Swelling.
- Headache or dizziness.
Precautions
- Allergic reactions: Rare but possible. Signs include rash, hives, difficulty breathing, or swelling of the face, lips, or tongue. Seek immediate medical help if these occur.
- Pre-existing conditions: Use with caution if you have severe liver or kidney disease or certain heart conditions, as the active ingredients are metabolized by the body.
- Not for other uses: Do not use Xylocaine NF for other types of skin pain, as it is formulated specifically for anal conditions.
