Purpose
Insect bite related symptoms (pruritus and papules) are caused by the release of histamine by mast cells in the skin. Topical anti-histaminics can be used to promote relief of these symptoms. Dexchlorpheniramine maleate 1% cream is a topical anti-histaminic formulation approved by ANVISA in Brazil for the relief of skin irritation and allergies, including the ones caused by insect bites. The aim of the present study is to demonstrate non-inferiority of a new pharmacological preparation of dexchlorpheniramine maleate (1% lotion) with the standard preparation (1% cream) for the relief of insect bite related symptoms and to demonstrate the safety of both preparations.

Primary Outcome Measures:
- Pruritus intensity at insect bite site, evaluated with a 10 point Visual Analogic Scale (VAS) [ Time Frame: 7 days ]
Secondary Outcome Measures:
- Composite clinical evaluation of erythema, pruritus and papule formation, performed by the investigator using a 4-point scale for each one of the parameters (absent, mild, moderate, intense). This evaluation constitutes the Insect Bite Score. [ Time Frame: 7 days ]

|---|---|
| Experimental: Dexchlorpheniramine 1% lotion |
Drug: Dexchlorpheniramine 1% lotion
Small amount applied over the lesion twice a day for 7 days.
|
| Active Comparator: Dexchlorpheniramine 1% cream |
Drug: Dexchlorpheniramine 1% cream
