Hi Dear,
Welcome to HCM.
Understanding your concern. As per your query you have dizziness and heart palpitations when on Effexor and Trazodone . Well the symptoms you mention in query can occur due to may reasons like strenuous exercise , caffeine , nicotine from tobacco , stress, anxiety ,
electrolyte imbalance ,
low blood sugar anemia ,
hyperthyroidism , over the counter medications, including cold and nutritional supplements and prescription medications, including beta blockers, asthma inhalers, and decongestants .
The symptoms can also occur due to side effects of certain medicine as your also mention Effexor and Trazodone , so also discuss condition with your doctor .
I would suggest you to
consult cardiologist for proper examination . Doctor may order ECG , blood test , urine tests , X-ray of the chest , coronary
angiography and take history to confirm the diagnosis . Treatment will depend upon the diagnosis .
Hope your concern has been resolved.
Get Well Soon.
Best Wishes,
Dr. Harry Maheshwari
