my husband had a cyst removed from his neck on Dec 9. He was given smz/tmp ds 800-160 tab interpharm. Dec 10 he started getting sick with weakness, nausea, sweating/chills, very tired and sleeping a lot. On Dec 13 we called the pharmist who recommended he stop taking the pills till seeing a dr. Saw the dr. on Dec 15 who determined my husband was allergic to the med and to stop taking the med. My husband is feeling better, but still very weak and sweats easily. Today, Dec. 16 he noticed the right side of his face/jaw is somewhat swollen. My question: could the swollen jaw be more aftereffects of taking the interpharm? PS - received a call today and the cyst was non-malignant.
