Paser (aminosalicylic acid) is an anti-tuberculosis drug used to treat tuberculosis in combination with other active agents. Paser is most commonly used in patients with Multi-drug Resistant TB (MDR-TB) or when isoniazid and rifampin use is not possible due to a combination of resistance and/or intolerance. Common side effects of Paser include nausea, vomiting, diarrhea, abdominal pain, and allergic reactions including fever and itching.
The adult dosage of Paser is four grams (one packet), three times per day. Smaller doses should be given to children; consult your doctor for pediatric dosing. Paser may interact with other drugs. Tell your doctor all medications and supplements you use. Paser may decrease the amount of substances (such as vitamin B12) in your body. Your doctor may recommend you take supplemental B12 while taking this drug. During pregnancy, Paser should be used only if prescribed. Consult your doctor before breastfeeding.
