Forum. Meclizine is a good medicine for vertigo, but in limit if cause is known. Since your husband is having repeated attack of dizziness, so cause may be as, 1 Congestive heart failure as you mentioned that his B P was 9444 mm of Hg, elevated to 13065 mm again 86. This is a common feature in congestive cardiac failures cases. Diagnosis can be confirmed by E K C, E C HO and consult a primary care physician due to the old age of patient. 2 Miners disease, diagnosis can be confirmed by examination by an E NT specialist. 3 Idiopathic reason, so get blood for sugar and lipid profile and consult a physician as physical examination is very important.
