I ws prescribed to use ranitidine twice . First time Zantac with combination of Keterol. Immediately after taking the drugs, i had severe itching and my eyes blacked out, pulse rate too fell down and ws rushed to hospital and given decodron injection. Second time, ws given Rantac with combination of Harpoon. The same happened again and this time rashes on the skin of legs, hands and choking at throat apart from itching and vomiting. since then i am scared of taking any drugs and always get tensed while using any new drug.
