We offer you to read the reviews of people who used Fenistil gel:
    The child constantly appears on the skin redness, from the bites of mosquitoes appear solid huge red blisters. Recently I found out that after a month newborns can smear Fenistil cream with red skin. The medicine is non-hormonal, therefore it cannot harm the child. I tried and now constantly use only this ointment.
    I have Fenistil ointment - a universal remedy for all unpleasant incidents. I use immediately after thermal burns at home, after application do not appear blisters. Successfully removes redness and discomfort after exposure to sunlight. I learned that you can use from mosquito bites. Need to try.
    Good for insect bites. In our family, everyone reacts to mosquito bites hard, with severe itching and redness. You smear with phenystyle - everything passes quickly. We use emulsion and gel too.

Parents often speak positively of phenystyle for children - in about 85% of cases. This is due to the rapid action of the drug, which literally within a few hours is able to relieve the allergic symptoms that bother the child. Moreover, drops are very popular in the fight against allergies, and gel is used to eliminate the effects of insect bites. Many children are combing the places of mosquito bites, itching keeps them awake and creates a feeling of strong discomfort. Gel perfectly relieves itching, eliminates swelling and redness, returning the child to a normal state.

Negative reviews about Fenistil for children are associated with its strong hypnotic effect and severity of side effects in the form of burning skin. In this situation, the drug eliminates the symptoms of allergy, but the severity of side effects outweighs the benefit, therefore, Fenistil is given a total negative assessment. After all, the drowsiness of the child makes parents very worried, looking forward to the end of the drug. And burning skin brings the child no less discomfort than the itch.
