Hi, I am 17 year old boy.In april 2017 I had severe headache accompanied with high fever 102 degree Fahrenheit. I went to doctor and he measured my bp. My bp was 150/90 pulse 80 bpm. He prescribed me Montelukast Sodium tabs .and antibiotic cefixime After taking the very first dose of Montelukast I had difficulty breathing, pain in my left chest and left arm and palpitations. The next day I went to doctor and reported this and he literally scolded me in his clinic in front of other people citing my lack of exercise, rtc etc. My height is 180 cm and at that time my weight was 80 kgs I went to another doctor and he stopped Montelukast sodium. Meanwhile I was suffering from typhoid. Typhoid was cured in 7 to 8 days. After stopping Montelukast I felt better, no more palpitations, etc.but I had occasional palpitations etc. After few days I again had breathless and pain in left side of chest. I went to doctor and my bp was 164 /80. I was very nervous there. Did ecg and it showed tachycardia. Went to cardiologist, he did an echo and report was fine. He said I was very anxious and nervous and prescribed me Vinicor D 25. Now it haz been 8 months but still I am taking the vinicor tabs. I get very nervous at doctor's clinic and my bp and pulse rate rises. My bp remains below 130 /80 at home. Is this tachycardia, excessive anxiety related to Montelukast Sodium tabs. I have no history of asthma. Currently my weight is 69 kgs and I exercise for almost 30 mins everyday. Pls help.
