Suggest Treatment For Inflammation And Allergic Reaction To Mosquito Bite

I have had a very bad reaction to mosquito bites. One on my nose, another at the side of my mouth and one on my cheek. They occurred at the weekend and have become inflamed since. They have been suppurating and are very sore and unsightly. I am wearing plasters on two of them to stop myself scratching more. I have some ointment that was prescribed for an eye infection some time ago. It is called Fucithalmic and contains Fusidic acid. It is the only antibiotic ointment I have and so I wondered if it would help the bites?
