Palpitations when taking anti-fungal

Hey everyone,

I was just curious if anyone has dealt with palpitations when starting and anti fungal. The two I've tried are grapefruit seed extract along with oil of oregano. They both gave me palpitations that gave me great anxiety and were kind of steaming right in my sternum. Not sure if it's a bad reaction or what is causing it. If anyone could let me know that would be great thanks.
