What is zantac (ranitidine)?

Antiacid stomach med: Zantac (ranitidine) is a histamine-2 (h2 blocker) which blocks acid secretion in the stomach. It can be used for esophageal reflux
(gerd) or other general hi acid states. It may be safer to use long-term than the other popular acid blockers (ppi's) e.g. Prilosec. Interestingly, since Zantac is a histamine blocker it can also be used for 'allergy' or hives. ...Read more

Accidentally took a Zantac (ranitidine) that is exactly 1 year past expiration date...How bad is that?

Probably not bad: There is a reasonable chance it won't do anything to help your heartburn, but otherwise probably not going to do any harm to take an over the counter (otc) past its expiration date. That being said, try not do that again! Throw out the package to prevent some mistakes. Routinely going through medicine cabinets to remove old and expired drugs is also always a good idea. ...Read more

Okay: We try to space out dosing because the drug wears off after a while and we want to cover most of the day. Bumping up a dose is unlikely to hurt but it also may not produce additional benefit. ...Read more

I have been taking Prilosec for 10 years. Trying to wean off with Zantac (ranitidine) 150/2 daily. Is there another drug I could use. Zantac (ranitidine) is giving me anxiety?

I have been taking Prilosec for 10 years. Trying to wean off with Zantac (ranitidine) 150/2 daily. Is there another drug I could use. Zantac (ranitidine) is giving me anxiety?

Depends: It really depends on why you are having reflux.
Best is to fix the root of the problem.
Long term stomach acid suppression can lead to micronutrient deficiencies and cause health problems. ...Read more

Does axid work better than Zantac (ranitidine) does?

In general or in you: Axid & Zantac (ranitidine) are 2 of many h2 blockers used to treat heartburn. As such, the manufacturer of Axid will tell you that Axid is better than zanac while the manufacturer of Zantac (ranitidine) will tell you differently (of course!). In large groups of patients, both are equally effective since they both work in same fashion. However, you may like one more than other (think of chevy vs dodge vs ford). ...Read more

Does Zantac (ranitidine) works for acid reflux? Would you recommend Zantac (ranitidine) for acid reflux?

Zantac (ranitidine) works 4 GERD: Zantac (ranitidine) was the leading drug in the world when introduced in the early 1980's to treat indigestion. Conventional prescription doses were 300mg twice daily. The drug is effective in suppressing acid, but when used longterm can promote tolerance (so that larger doses are needed over time to block acid). Current over-the-counter dosing is 75mgs. Take along with behavior & diet aimed at reducing gerd. ...Read more

My 18 day old is on 1 ml of Zantac (ranitidine) for 5 days now. She still has the arching of the back and painful cry. How long until meds kick in? New meds?

My 18 day old is on 1 ml of Zantac (ranitidine) for 5 days now. She still has the arching of the back and painful cry. How long until meds kick in? New meds?

Not a quick fix: Every baby has some reflux & some have more symptoms than others. The backwash of stomach acid produces the equivalent of a sunburn on the inside of the swallowing tube & that hurts. The Zantac (ranitidine) reduces the acidity some but it is not a pain controler. It just gives the gut a better chance to heal. After a week or 2 on meds u should see improvement. Discuss some other things u can try with the dr. ...Read more

Does taking ranitidine Zantac and marijuana have a side effect yesterday around 1 pm I took a ranitidine and last night around 8:30 I smoked some marijuana and everything was all blurry and I fainted three times

Tagamet/Zantac: This class of drugs is a well known inhibitor of the enzymes used in the liver to break-down or de-toxify many medications/drugs. So your usual thc hit stayed around, and its intensity increased, by your use of ranitidine. ...Read more

How long should bronchiolitis last in 3.5 month old. She's on albuterol and Pulmicort nebulizers, and Zantac (ranitidine) 3xday. Could it be more serious?

How long should bronchiolitis last in 3.5 month old. She's on albuterol and Pulmicort nebulizers, and Zantac (ranitidine) 3xday. Could it be more serious?

A month: The coughing and wheezing from bronchiolitis can last for a month. Typically it lasts about ten days, but it is not at all unusual to last 3 weeks or more. Follow up visits with your doctor weekly would probably be a good idea as other problems could occur such as an ear infection. ...Read more

My 7 wk old got put on Zantac (ranitidine) and enfimal nutramigen a day and a half ago but vomited yesterday night. Why is he back to crying while trying to burp?

My 7 wk old got put on Zantac (ranitidine) and enfimal nutramigen a day and a half ago but vomited yesterday night. Why is he back to crying while trying to burp?

Takes time to improv: Kids on this rx generally have reflux that causes heartburn. This process will improve gradually as the meds begin to help, but continued wet burps are quite common & sometimes persist in spite of rx. As long as baby continues to gain weight, you can continue rx & have a recheck periodically. ...Read more

Can I take 3 Zantac (ranitidine) at one time?

Not recommended: Risks outweigh benefits. Taking three 150 mg pills probably would not cause toxicity though it also would not likely provide more relief. Current recommended dosages for Zantac (or ranitidine) for most conditions is 150 mg twice daily or 300 mg once at bedtime. Patients with erosive esophagitis may benefit from 150 mg four times daily but dosages are about every 6 hours, not all at once. ...Read more

Can I take Zantac (ranitidine) with omaprozle?

Omeprazole/Zantac: Although you can take it together, it is unlikely you will get much more relief than your prescribed omeprazole. If the omeprazole that has been prescribed by your doctor is not controlling your symptoms well (if you are still having symptoms more than three times per week), you should mention it to your doctor to alter your dosage or your medication. Anti-reflux measures can help also. Good luck. ...Read more
