Question: Yesterday Dr. XXXXXXX prescribed Sulfamethoxazole-TMP DS Tablets for my husband, XXXXXXX to take 2x daily for 7 days for a UTI. He took two yesterday & has already taken two today. He has had a temperature all day & now it is 101.2°F. He has been in his recliner or on the couch except for a very few trips to void & to eat some food, which has not been much. I wonder if it is the UTI causing him this fever and no energy, or is he having side effects from the Bactrim Substitute. XXXXXXX had a heart attack on July 9, so I'm trying to be extra watchful. I even wonder if he is dehydrated. Wife XXXXXXX XXXXXXX weighs 177 lbs & is 68 in tall. His BMI is 26.93. His heart rate 75/min & Respiration rate 16/min. His meds are ZyrTec Allergy 10 mg, Symbicort 160-4.5 MCG/ACT Inhalation Aerosol 1x daily, Tylenol Extra Strength 500 mg at night, Brilinta 90 MG Tablet 2x daily, CoQ10 100mg, Metoprolol Tartrate 25MG 1/2 tablet 2x daily, Magnesium Oxide 400mg Tablet, Rosuvastatin Calcium 40 mg Tablet, Xopenex HFA 45 MCG/ACT Inhalation Aerosol (1-2 puffs 4x daily as needed); Aspirin 81 mg Tablet, Nitroglycerin 0.4 MG Sublingual Tablet as needed, Albuterol Sulfate (2.5 MG/3ML) 0.083% Inhalation Nebulization Solution every 4-6 hours as needed & Esomeprazole before breakfast. XXXXXXX complains often with his arms & shoulder and sometimes his thighs hurting. Dr. XXXXXXX just had him take X-ray of his knees, but no result yet. He has Allpha-1-antitrypsin deficiency. His normal habit is to take a morning & afternoon nap; however, today he has napped on and off all day long!
