Worming medications may or may not pull worms when taken, and each type of medication is different and plays a different role. The main types of worming medications include piperazine phosphate botulinum toxin and mebendazole. Worm pulling symptoms may occur after taking Piperazine Phosphate Botulinum Sugar. The main principle of action of Piperazine Phosphate Botulinum Sugar is to anesthetize the roundworms, so that the parasites can not attach to the intestinal wall of the host, and thus be expelled from the body. Symptoms of pulling worms may not occur after taking mebendazole. Mebendazole generally blocks the parasite’s absorption of glucose and other nutrients, allowing the worms to die and killing their eggs, so pulling worms usually does not occur. After taking the worming medication, you need to observe the individual’s physical condition, and if there is any abnormality, it is recommended to actively seek medical attention.
