Aminopyralid is an antipyretic and analgesic medication that is often used to relieve fever, muscle aches, and sore throats due to colds or flu, as well as to relieve toothache and neuralgia. You need to be aware of this when using the medication, leading to a number of adverse reactions. Particular attention should be paid to the aspect of gastrointestinal damage, causing dyspepsia, damage to the mucous membranes, leading to gastric ulcers, duodenal ulcers, and even leading to bleeding. Therefore patients with gastrointestinal bleeding and peptic ulcers are prohibited from applying aminopyralid. Some other adverse reactions are also concerned with the risk of kidney damage, the risk of liver damage. Renal and hepatic functions need to be monitored when the drug is used in large quantities or for a long period of time. The last point to be noted is that it can lead to a decrease in white blood cells, and the same care should be taken to check the blood count during the administration of the drug.
