How can i make this stop?!?

[kramer205]

about 2 months ago my doctor gave me Bactrim for my acne. about a week later once i would start to work out and i would sweat my sweat would cause me to break out in hives. he told me to stop taking bactrim and for about a month although i had stopped taking the medicine it would still happen. so whether i take bactrim or not now i get the hives whenever i sweat. what is causing this and how can it stop???

Hi,

Physical activity that may lead to sweating may cause allergic symptoms in some people. Aside from h, otsymptoms may include itching of the skin, flushing, difficulty breathing,  stomach cramping or headaches. As soon as you notice the hives, you should stop what activity you are doing. If the hives do not go away in 5 to 10 minutes, or if you have other symptoms, it is important that you see inform your doctor.  Medications such as certain antihistamines, can prevent symptoms in some cases. It would help if you avoid any activity that leads to sweating.

Take care and regards.

so is this condition permanent? or is it only temporary since it has been caused by the medicine

This could just be temporary. Antihistamine medications and avoidance of the trigger (sweat) may help. However, do you have a personal or family history of allergies? If it persists, see your doctor for further evaluation. A complete medical history and physical examination  will help in determining the outlook.

Take care and keep us posted.
