Been a complete idiot this evening and swallowed a dose of my normal morning medication (Lisinopril 5 mg) instead of the vitamin pill I intended to swallow.
The normal daily dose of Lisinopril is 20 mg and when I googled I actually found a research report that found two daily doses might be more effective. So there don't seem to be any safety implications of splitting a 10mg dose, which is effectively what I've done.
Does it sound like I don't need to ring 111 or anything over this? I know the dangers of relying on Dr Google but it does seem like I haven't done anything likely to be dangerous.
