Feeling really anxious about having taken these drugs very close together. Forgot I had taken a Pepcid before eating, then felt unwell after eating and took a Zofran. Once it dawned on me I searched on Google to see if there were any drug interactions and the consensus is that there is a risk of fairly serious side effects involving irregular heartbeat, albeit it a rare one. Has anyone ever experienced this? Or is this a case of Google always putting the worst possible scenario of anything in your face? I keep talking myself down (in a different group one woman said it was fine and that she takes them together regularly, also thinking my doctor wouldn't suggest to take pepcid if zofran were on my med list if the 2 really shouldn't be mixed) but then I get worked back up again just thinking about the symptoms.
