Yes, your father should continue taking his daily blood pressure medication, Telvas 3D (which contains telmisartan, amlodipine, and hydrochlorothiazide), without any interruption after getting his Covaxin vaccine. There is no need to wait or skip his dose. Maintaining stable blood pressure is crucial for his health, and his medication will not interfere with the vaccine's effectiveness or safety. Please ensure he stays well-hydrated. If he experiences common, mild vaccine side effects like fever or body aches, these can be managed safely, but his daily blood pressure routine should continue as normal.
