When son was approx 25 lbs he was prescribed ranitidine 15mg/ml at 2 mls twice daily. He now weighs 32 lbs. Is the dosage the same?

When son was approx 25 lbs he was prescribed ranitidine 15mg/ml at 2 mls twice daily. He now weighs 32 lbs. Is the dosage the same?

Depends: You are right in thinking that since he has increased his weight, his medication should also be increased since pediatric medicines are dosed based on weight. To roughly stay the same, you could give him 2.5 ml twice daily. If it is hard to measure out 2.5 ml, you could safely give him 3 ml twice daily. Sometimes doctors will keep the dose the same, and if the lower dose works as well, that is ok. ...Read more

Can I take a 150mg ranitidine and a 2mg Xanax (alprazolam) together safely and will the ranitidine affect the absorption of the xanax (alprazolam)? Thank You

Can I take a 150mg ranitidine and a 2mg Xanax (alprazolam) together safely and will the ranitidine affect the absorption of the xanax (alprazolam)? Thank You

No interactions: Or differences in absorption with ranitidine and alprazolam. You don't list Xanax on your medications, and 2 mg is a hefty dose of this very potent drug. This would be a dose that someone would have been built up to if lower doses didn't work. The starting dose of Xanax should be about 0.5 mg if you have not been on it before. If it is prescribed for you, your doctor/pharmacist can advise you. ...Read more

Is it ok to take 150mg of ranitidine with a 500mg Tylenol (acetaminophen)?

Is it ok to take 150mg of ranitidine with a 500mg Tylenol (acetaminophen)?

One time?: While zantac and tylenol (acetaminophen) are both liver metabolized they do not have significant interactions with each other and have decent margins of safety.
BUT
tylenol (acetaminophen) in large amounts (at one time) is quite toxic to the liver; and many medications have tylenol (acetaminophen) in them.
So.... tylenol (acetaminophen) + Percocet + cold medicine might NOT be safe. ...Read more

How long does it take for ranitidine to leave you system? Been taken even other day for about two months of 150mg

A few days.: Ranitidine does not last long in your body. If you stop taking it, then your stomach acid will not be reduced after just a few days of stopping it.

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

Anti-reflux measures can help also. Good luck. ...Read more
