I'm really worried about my dad. He just had angioplasty with stents put in last month, and now he's dealing with a heavy cold, runny nose, and watery eyes that wont quit. He's already on a bunch of meds for his coronary disease, so I'm hesitant about what to give him for relief. Do you think cetrizine is okay to help with the runny nose, or is there anything else you'd recommend that won't mess with his existing meds?
For treating the cold symptoms without interfering with his current medications, you can give your father cetirizine. The recommended dosage for cetirizine is 5-10mg once daily. This antihistamine will help relieve his runny nose and watery eyes without causing significant interactions with his coronary disease medications.
