I take ritalin (methylphenidate) (40mg), have occasional pvcs and pacs, but all tests (ekg, 24h ekg, ultrasound, etc) were normal. dr says anxiety/panic. what to do?

High dose ?: Try and reduce the dose of Ritalin (methylphenidate) by 10 mg at a time. It should reduce some of the anxiety you are experiencing.

Ritalin (methylphenidate) / Stimulant : Used for add/adhd, narcolepsy. It increases norepinephrine and Dopamine concentration in brainstem, midbrain and frontal cortex with resultant improvement in daily living skills. Cardiovascular side effects: increased heart rate/ bp, arrhythmia, chest pain. Anxiety is one contraindication to use ritalin (methylphenidate). If your pac, PVC and anxiety is of resent onset after starting ritalin (methylphenidate), get second opinion.

See a psychiatrist.: Psychiatrists are trained to evaluate and treat exactly what you desribed/asked. While there are many reasons you could be having pvcs and pacs the results so far are encouraging. There are a number of treatment options for anxiety and panic.
