Can I take Pyrantelum for pinworm or drink alcohol while taking Glucophage?

There should be no harmful interactions between the drugs mentioned by you. Please remember that combining alcohol with medicines can have unpleasant consequences for health. The combined use of Glucophage with alcohol can cause an increase in the concentration of lactic acid in the body - lactic acidosis. This is manifested by general malaise, significant weakness and muscle aches, nausea, vomiting, diarrhea, abdominal pain, deep or accelerated breathing (Kussmaul breath). This is a rare, but dangerous (with high mortality) complication. I also encourage you to read the article: https://www.gdziepolek.pl/artykuly/czy-mozna-laczyc-leki-z-alkoholem
