Short answer Living with aminocaproic acid: what to watch for Common questions Related questions Sources**Most side effects of aminocaproic acid are mild and short lived, such as nausea, stomach upset, headache, dizziness, and nasal stuffiness.**
How you feel depends on the dose, how long you take it, and whether you get it by mouth or by vein. Fast intravenous dosing can drop your blood pressure and cause flushing, so it is given slowly. Higher doses taken over weeks can irritate muscle tissue, causing aching, weakness, and dark urine, and your care team may check a blood test called CK. Because the drug works by slowing the breakdown of clots, blood clots are a possible risk, which matters most if you have had a clot, are immobile, or have kidney problems. Taking oral doses with food and spreading them evenly through the day helps with the stomach effects.

Common questions
What are the side effects of Aminocaproic Acid?
Common side effects include nausea, vomiting, diarrhea, stomach cramps, headache, dizziness, nasal congestion, and watery eyes. Intravenous doses given too fast can cause flushing and a drop in blood pressure. Longer or higher dose use can cause muscle pain and weakness from muscle breakdown, so your clinician may check a CK blood test and kidney function. Because the drug slows clot breakdown, clots are a possible risk. Call your clinician promptly for muscle pain or weakness, dark or reduced urine, chest pain, trouble breathing, one sided leg swelling, confusion, or a spreading rash.
