Canada \u00b7 Rybelsus
Rybelsus in Canada: the semaglutide tablet, side effects and user reports.
Short answer
Rybelsus side effects are mainly gastrointestinal: nausea, diarrhoea, vomiting, abdominal pain and constipation, most often early in treatment. The label carries the same pancreatitis, gallbladder and thyroid C-cell warnings as injectable semaglutide.
