Your doctor will help you decide the best way to take ranitidine (brand name Zantac). It is available in several forms: a pill that you swallow, an injection in a muscle or an infusion into a blood vessel. If you cannot take the pill form of ranitidine, an injectable form of this medicine may be better for you.
Depending on the condition for which you are being treated, you may take ranitidine hydrochloride up to four times a day. If you are getting an injection, you may get a large dose every six to eight hours. With an infusion, smaller amounts may be continuously delivered through a tube in your vein (an intravenous catheter, also called an IV).
