After 4 days of taking praziquantel albendazole piperazine and dontril my youngest swelled up and my the glands in my throat were swollen and sore. I was also taking herbs and vitamins. Do you have an opinion on why this might have happened? Would appreciate any advise you could give me. I wasn’t following this protocol. But close. It was mattk3. His final formula. I had to discontinue.
