Question 1

can you have an overdose on zantac (ranitidine)?

Accepted Answer

Of course by why?: Zantac (ranitidine) when therapeutically dosed is 150-300mg twice daily. Over time, patients may develop tolerance to the drug but further dosing is unwarranted. If you have dyspeptic symptoms refractory to zantac, or your symptoms progress, don't exceed the recommended dose but get evaluated.

Question 2

what is the definition or description of: zantac (ranitidine) overdose?

Accepted Answer

Zantac (ranitidine): Zantac (ranitidine)  is an antacid / antihistamine.
 An overdose is when an excessive or dangerous amount of a medication or substance is used.

Question 3

can you overdose on zantacs (ranitidine) after 4 hours of no side effects?

Accepted Answer

Overdosing: I am always worried about questions like this from teenagers.  I am worried because there seems to be a time when teens feel like harming themselves. If you are feeling suicidal please ask for help. If you cannot approach your parents then please get to an adult you trust.  Your pediatrician may be a good choice.

 But, to the question, no this medication cannot cause over dose.

Question 4

can an infant overdose on zantac (ranitidine) my sons dr prescribed him way to much, and was on it for a month should i be concerned?

Accepted Answer

Large safety margin : I would not worry about it too much, but i would need to know the exact dose and the infants weight to be sure.

Question 5

how many tablets of zantac (ranitidine) 150 does it take to overdose? suppose to take two but took three instead

Accepted Answer

You : You are correct - the maximum dose of Zantac (ranitidine) is 300mg or 2 tablets.  That being said, accidentally taking an extra one once should not be dangerous.  If you have any specific concerns you can always call the poison control center toll free at 1-800- 222-1222.

Question 6

can zantac (ranitidine) 150 cause decrease in appetite? took a few times in a week, appetite lower. once stopped it was fine

Accepted Answer

Not usually: Zantac (ranitidine) does not usually have that side effect, but everyone is different. If you are having less appetite after taking it then I would avoid it and try another medication if you are having heartburn.

Question 7

my son is 1 and has been on zantac (ranitidine) for about 10 months and now is showing a high ferratin level ? can zanta cause this to happen ?

Accepted Answer

No: Zantac (ranitidine) does not cause high ferritin. I assume that your son has been on zantac (ranitidine) for gerd. Gerd does not cause high ferritin either. Ferritin does go up with infections or inflammations. It goes down when they subside. Ask your pediatrician  reasons for testing serum ferritin, because it is not something we do routinely. If it is very abnormal, then you need the doctor anyway..

Question 8

will zantac (ranitidine) cause a false postive on a urine test?

Accepted Answer

For what?: False positive is when the result is positive for an analyte when it is not there. Specific drugs may cause false positives, but you need to know what is being tested for.

Question 9

i have been taking zantac (ranitidine) (acid refulx tablets) for 3 yrs daily, could this have caused long term health problems or deficiencies?

Accepted Answer

Safety of Zantac (ranitidine): I believe you are taking  forsymptoms arising from acid  in the stomach.  Long term stomach acid suppression is needed to suppress symptoms arising from  it or due to history of stomach ulcers., although more effective medicines  called as proton pump inhibitor  are available even over the counter sold as omeprazole.  Long term effects of acid suppression may include calcium and vit d deficiency.

Question 10

does rebeprazole cause acid rebound if taken on "as needed basis"and not everyday (took only when pain in stoamch-2 times a week) compared to zantac?

Accepted Answer

As needed: I believe zantac or pepcid are better choices to take as needed as they are faster acting than ppi's like rebeprazole  Ppi's are most effective when taken in the morning on an empty stomach before certain stomach cells start to secrete acid.
