Anjali, most of the drugs should not be taken on empty stomach. Unless specified, they should be taken only after food. Saridon is the oldest pain killer. It contains Paracetamol
, Caffiene & Propoxyphenazone. Paracetamol & Propoxyphenazone are used to relieve mild pain. Caffiene is a stimulant.
The symptoms you are feeling are due to hyperacidity
. Though infrequent paracetamol can cause gastric irritation when taken on empty stomach. Disprin, taken on empty stomach can result in haemetemesis (vomiting of blood).
Pain killers should not be used indiscriminately. They should be taken only when you have pain. Frequent use will cause liver damage
. Also severe pain
like neuropathic pain
(pain due to nerve problem) cannot be controlled by Saridon or Disprin. So pl visit your Dr. to find out the cause for your chronic (prolonged) pain instead of taking pain killers
