My mother took some sulfamethoxazole-tmp ds that I had from when I had pneumonia, now she is having some side effects such as sore throat, fever, itchiness, needle pricking over her body, ears are hurting and her chest is hurting. What should I do I researched that these side effects could be very serious. Is there any way I can help? I ve managed to keep her very well hydrated, but I need to know what else I can do for her?
