Accidentally took a naproxen


I went to take an antibiotic yesterday morning and just realized this evening I accidentally took a 500mg naproxen instead of my pill. My husbands prescription bottle was sitting on the table and I thought it was mine without even looking. I have an appointment with my OB Monday and will mention it then but I was just wondering if anyone thought this could cause any harm. He’s been very active today so I’m not sure if I should worry myself or not. (Holy run on sentence 🤣)
