I Have Had Dizziness For Couple Of Days. Use A

I have had dizziness for couple of days. Use a walker or cane to get around the house but mostly am in bed. Feel like I have chills too. Ok to take meclizine? On Atenolol and hydroclorathiazide (sp?) for HTN. Feel dizziness is less severe today but don't feel well enough to get to the doctor's office.
