Dear Concerned., Thanks for writing to us. The medicines prescribed by your Psychiatryst are for treating your Depressive Neurosis with antidepressants , beta blockers and anxiolytics. The side effect of antidepressant (selective serotonin re uptake inhibitor)being dryness of mouth/insomnia/dizziness and the same dosage is gradually increased to reduce the side effects and also to obtain the desired levels of Serotonin in the brain so that the depression of an individual gets cured by pharmaco therapy. Betacap TR 40 by its beta blocker effects on the heart produces reduced heart rate and also reduces BP.The effects of anxiety include Tachycardia and irregularly raised BP, the reduction of same is being achieved by sympatholytic action of B-Blockers. As you get used to the heart rate produced over a period of time,there will not be any lifethreat with the same pulse rate. If you feel weak, kindly take plenty of oral fluids/electrolytes/fruitjuice with a pinch of salt /tender coconut water in addition so that this side effect can be reduced. If your BP is 137/77 mm Hg , this need not produce any worry at all as this falls within the normal range for you at your age. kindly consult your Psychiatryst before abruptly stopping any of these medicines as the rebound effect of relapse of depression/anxiety will have to be dealt with by him only. Please request the specialist for a detailed Psychoanalysis and Psychotherapy as your condition seems to be more of a Mood disorder which can be corrected by knowing the root cause/basic pathology and then solving them step by step. wishing you a speedy recovery., Best Regards., Dr Lt Cdr ASN Bhushan., Ex-Navy
