Effective Treatments for Scabies: Options and Considerations - Dermatology

More Info

---

Scabies, caused by the Sarcoptes scabiei mite, is a highly contagious skin condition characterized by intense itching and a rash, often worsening at night. Your symptoms, including red papules and itching in areas like the armpits and groin, align with a scabies diagnosis. The treatment options you mentioned are commonly used in Taiwan, and I will elaborate on each, including their effectiveness and potential side effects.

1. Sulfur Ointment: This is a traditional treatment for scabies, typically containing 5% to 10% sulfur. It is applied for three consecutive days. While effective, it has a strong odor and can be greasy, which some patients find unpleasant. However, it is safe for use in children and pregnant women, making it a versatile option.

2. Eurax Cream or Lotion (Crotamiton): This is applied for two to five days, depending on the specific product instructions. While it can be effective, some studies suggest its cure rate may be lower than other treatments. Side effects can include skin irritation or allergic reactions, particularly in sensitive individuals.

3. Mitigal (Containing Mesulphen): This cream is applied for three days and is known for its effectiveness. However, it can cause skin irritation, especially in sensitive areas. Given your history of allergies, it’s essential to monitor for any adverse reactions. If you experience significant irritation, discontinuing use is advisable.

4. Benzyl Benzoate Lotion (BB Lotion): This lotion is applied for three days and is also effective against scabies. It can be irritating to the skin, particularly in sensitive individuals. Side effects may include burning sensations or rashes, so caution is warranted.

5. Gamma Benzene Hexachloride Cream (Scabi): This treatment is applied for one day and left on for 12 to 24 hours before washing off. While it is effective, it has a higher toxicity profile and should be used cautiously, especially in children and pregnant or breastfeeding women. Due to its potential side effects, including neurotoxicity, it is generally not recommended for prolonged use.

Regarding your concern about the persistence of symptoms despite treatment, it is crucial to ensure that the entire household is treated simultaneously to prevent reinfestation. Scabies mites can survive away from the human body for a short period, and their eggs can hatch, leading to a resurgence of symptoms if not adequately addressed.

As for your question about the potential for allergic reactions causing pain in the kidney area, it is unlikely that scabies or its treatment would directly cause kidney pain. However, if you have a history of allergies, it’s possible that you may be experiencing a reaction to something else in your environment or a side effect of the medications. If the pain persists or worsens, seeking medical attention is advisable.

In terms of your studies and preparation for exams, managing your symptoms effectively is crucial. If you find that over-the-counter options are insufficient, consider consulting a dermatologist for a prescription treatment that may be more effective and less irritating.
In summary, while there are several effective treatments for scabies, the choice of medication should consider your specific symptoms, potential side effects, and any underlying health conditions. Monitoring your skin's response to treatment and adjusting as necessary is vital for achieving relief and preventing further outbreaks.
