Albendazole is used to treat parasitic infections in Europe and Asia, and they are available over the counter.
Praziquantel is an American drug that is a CHEMOTHERAPY drug which is prescribed for people in the United States with parasitic infections.
Metronidazole is an antibiotic, antibacterial, anti parasitic drug for multiple types of infections, but rarely used for parasitic infections.
Which drugs have you found the most effective? Myself? I definitely think I released the most amount of parasites- whether Tapeworms or otherwise when I took Fluconazole (for yeast infection) and also Metronidazole, which seems to kill tapeworms, flukes and pinworms.
I definitely would not take Praziquantel as medical studies have been showing it has multiple negative side effects, and Albendazole is just as effective in higher doses.
