What Are The Side Effects Of Overdose Of Potassium?

Hello, I hope you are available now. I had OHSS after egg retrieval in IVF procedure. Transfer was postponed till I get better. Doctor gave me Lasix 40 mg to be taken once and Neo-K (potassium chloride) 500 mg twice daily for 5 days for now. My concern is that I ate two potatoes, one banana, a cup of yogurt, and tomato, all potassium sources today. Should I take my evening dose now without danger of potassium overdose?
Thank you.
