Have you been bitten by a mosquito, stung by a wasp or bitten by another insect? Do you feel itching, burning and pain, and the place is swollen? In the pharmacy you can buy over-the-counter gels and ointments antipruritic and anti-edematous. If you feel pain at the site of the prick, a cooling stick with menthol can bring relief. You can also buy oral anti-inflammatory and antiallergic drugs without a prescription that will relieve the symptoms of the bite.
