My voice has been hoarse for some time and seem to have excessive flim in my throat all of time that I try to clear out by coughing and spit it out. I went to a throat specialist about it. He said I have acid reflux and prescribed for me lansporazole, 30 mg, cap, to take two times a day, 30 minutes before meal. I have not taken the medicine yet as I am afraid it might interact with allopurinol , lisinopril , vitamin D3 , and aspirin 81 mg, I take everyday. Is it safe for me to take lansporazole with these medication? and, Will it solve my problem? Sua Pea
