Tetramizole: instructions for use in veterinary medicine

The granules contain 10% d1-2,3,5,6-tetra-hydro 6-phenyl-imidazo (2,1-b) thiazole hydrochloride.

Tetramizole is a broad-spectrum anthelmintic agent. It is used to prevent gastrointestinal and pulmonary nematodoses in ruminants and pigs. Effective against all major gastrointestinal and pulmonary nematodes. The drug simultaneously destroys almost all mature and immature forms of parasites. Due to the low toxicity and breadth of the therapeutic spectrum, there is practically no danger of developing toxic reactions in case of drug overdose.

The drug has a rapid effect, and is also rapidly inactivated and excreted from the body, so its effect ceases two days after taking the last dose. In animals invaded by pulmonary nematodes, already after 15-20 minutes after the use of tetramisole, cough increases, which ceases during the next day. Tetramisole only destroys pulmonary parasites, but does not cure the organic disturbances caused by them. Diarrhea caused by invasion of gastrointestinal parasites, passes in two days. Animals receiving the drug quickly recover due to increased appetite and better absorption of food. In therapeutic doses, tetramisole does not cause any side effects. Animals tolerate the drug even in doses several times higher than therapeutic. Tetramizole does not adversely affect young animals, or weakened and pregnant animals.
