I am on the antibiotic sulfamethoxazole-tmp for over eight months for acne. i've been having major loss of appetite, is this something to worry about?

Drug: May be a side effect of the drug. See your primary care for a complete checkup to look for other causes of weight loss. Call the dermatologist to see if there are other antibiotics you can take. Also be sure you are taking a probiotic to replace the bacteria of your intestine in case the weight loss is due to malabsorption from a change in the bacteria of the intestines
