Common questions about Perlice (FAQ)
Q: Is Perlice available over-the-counter or does it need a prescription?
The availability of Perlice depends on its specific concentration and formulation. The 1% lotion or cream rinse, typically used for head lice, is generally available over-the-counter. However, the 5% cream formulation, which is often used for scabies treatment, usually requires a prescription according to official product information.
Q: What steps are described if someone accidentally swallows Perlice?
Permethrin is intended for topical use only and must not be swallowed.

Official information specifies that vomiting should not be induced.
Q: What happens if Perlice gets into the eyes?
Official product safety notes indicate the importance of avoiding contact with the eyes during application. If the product does accidentally get into the eyes, regulatory guidance describes flushing or rinsing the area thoroughly with water immediately to minimize potential irritation.
Q: Is there a limit to how many times Perlice can be used?
The official treatment guidance outlines specific re-treatment rules, typically allowing a single repeat application 7 to 14 days later if live organisms are observed. There is no maximum limit defined for total lifetime use, but any reapplication beyond the established single repeat requires regulatory guidance and professional assessment.
Q: Does Perlice have a shelf life or expiration date?

Q: Can people with asthma or allergies use Perlice?
The product is strictly contraindicated for anyone with a known hypersensitivity or allergy to the active ingredient, permethrin, or other components. Furthermore, regulatory warnings note that the cream may potentially worsen existing symptoms of skin conditions like eczema or respiratory conditions like asthma.
Q: Can Perlice be used if I have open cuts or sores on my skin?
Official safety instructions advise users to avoid applying the cream to mucous membranes, such as the inside of the nose or mouth, and to avoid contact with open wounds or sores on the skin.

The official regulatory indication for topical Permethrin is limited to the treatment of two conditions: scabies and head lice. Only the officially approved uses are included in the product labeling.
Q: Are there any long-term effects associated with using Perlice?
The majority of common, localized effects, such as treatment-related itching, are temporary and typically resolve within a few weeks of successful treatment. However, official labeling notes findings from animal studies regarding potential long-term effects that inform specific caution for use in sensitive populations, such as during pregnancy and nursing.
Q: How quickly should I expect Perlice to start working?
According to regulatory documents, a single application is generally described as effective for clearing the parasitic infestation swiftly. Regulatory guidance notes that persistent symptoms like itching and skin irritation are common for up to a few weeks after treatment and do not necessarily indicate treatment failure.
Q: Can Perlice affect my sleep or mood?
Regulatory documents report some systemic adverse reactions, such as headache or dizziness, though these are typically classified as having 'Not Known' or 'Rare' frequency. There is no specific, dedicated information provided in the official documentation regarding the product's effect on a person's sleep patterns or general mood.
Q: Is Perlice known to cause any temporary discoloration of the skin?
Official regulatory documents list reduced skin pigmentation (discoloration) as a potential adverse reaction. This is classified as a Very rare event, meaning it is expected to affect fewer than 1 in 10,000 people who use the medication.
Q: Has Perlice been studied in different ethnic groups?
Research into the active ingredient is conducted in various and diverse geographic populations as part of clinical trials and ongoing post-market surveillance. This helps ensure a broad understanding of the drug's efficacy and safety profile across different global populations.
