Hello Sir, I am 61 years old, and a patient of PITUTARY ADENOMA TUMOR. Had been operated in 1995, 2005, 2009 and 2013 at AIIMS for tumor removal. First three operations were surgical and last in 2013 was through GammaKnife. I have also suffered 3-4 episodes of TIA strokes in past 3 years. Lastly I suffered a TIA was in 27th January 2021. And, I also have hypothyroidism and diabetes. I have been taking medication like Wysolone 5mg, Thyroxine 100mcg, Sitagliptin 50mg, Glimperide 1mg, Metformin 1000mg, ROSUMAC GOLD 20, Amlovas-AT, Serenace 0.5mg, Shelcal 500, Testoviron 250mg injection every 3 weeks, Levipil 500mg (BD). I am currently doing fine with my current medications. ----------------------------------- So, can I take COVISHIELD vaccine safely, do I have to be concerned or pause some medicines?
