Hello ssmith42469, Welcome to the forum. Yes, your symptoms are of allergic reactions. These are side effects of Levaquin, some patients who are sensitive show such response, while many just do fine with it. Don t worry. You will get fine soon. You should apply cold compress in the areas where the itch is troubling you most. You can even apply a cold soft towel so that the itches reduce and you feel more comfortable. If you want you can apply Calamine lotion or hydrocortisone cream on your skin ( not inside your mouth). Consult a local doctor as few antihistamines could give relief to your tongue. Before taking medicines and during consultation you should give a detailed history to your doctor regarding your health and if you had any past illness, surgery or any other disease. You should inform your treating General practitioner if at all you are allergic to any medicine (in this case allergy to any of the medicines belonging to the fluoroquinolone group ) Levaquin has many side effects like swallowing difficulties, throat problems, sudden hoarseness, constipation, gastritis, nausea, headache and many more. You are lucky not to get all these. But if after taking levaquin you have symptoms like muscle weakness, joint pain, breathing problem, etc you should immediately report to your treating physician. Hope you are informed that 2-3 hours after you take levaquin you should not take antacids or any vitamin or mineral supplements. Always take levaquin after having a nice filling meal. I will suggest you to take a lot of pure, hygienic water or boiled and cooled water to flush out the toxic effects of the medicine. You should also take plenty of fruits, juice and soups to feel yet better. Have a good day, take care.
