I have been taking 4-5 tablets of 150mg zantac each day for the past 2yrs... will this harm me?

All meds have side effects but most get differently effected, most common Side Effects of Zantac, Zantac has been thoroughly studied in clinical trials, with many people being evaluated. In these studies, side effects occurring in a group of people taking the drug are documented and often compared to the side effects that occur in a similar group of people not taking the medicine. This way, it is possible to see what side effects occur, how often they appear, and how they compare to the group not taking the medicine.

Based on these studies, the most common side effects of Zantac include: Headache; Constipation; Diarrhea; Upset stomach (nausea) or vomiting; Abdominal pain (stomach pain); Rash.

Some side effects to report to the doc/pharmacist are: Confusion, agitation, or hallucinations; Depression; Heart problems, including: Fast heart rate (tachycardia); Slow heart rate (bradycardia); Abnormal heart rhythms (arrhythmias).

Symptoms of liver problems or hepatitis, including: Yellowing of the eyes or skin; Pain in the upper-right side of the abdomen; Dark urine; Angioedema (life-threatening swelling of the throat and mouth); Signs of an allergic reaction, including: An unusual rash; Hives; Itching; Wheezing; Trouble breathing; Swelling of the mouth or throat.

Rare Zantac side effects occur in only a few patients taking the drug. Because these side effects are so uncommon, it is difficult to tell whether they are actually caused by Zantac or something else.

Some of these rare but possible side effects include: Dizziness or a spinning sensation (vertigo); Drowsiness or sleeping difficulty (insomnia); Muscle pain or joint pain; Hair loss; Increased risk of pneumonia; Blurred vision.
