What causes dizziness after taking St.John s Wort?
Patient: I started taking St Johns Wort a week ago but I was only taking one a day for a few days . Then I started taking one twice a day until yesterday I started one 3 times a day . I noticed because I did a couple times take two at once that it made me dizzy ... My question is If I continue taking one 3 times a day for how long do I continue taking St Johns Wort? Doctor: Hello,  It might be due to first dose effect. As of now drink plenty of water and take rest. If symptoms persist, better to consult a physician and get evaluated.  Hope I have answered your query. Let me know if I can assist you further.  Take care  Regards, Dr Shinas Hussain, General & Family Physician
