One of the most common barrier to reporting observed or suspected ADR is because doctors belief that if they did this, they will be litigated for medical negligence. This is not true.

In fact, there are cases of medical litigation but these were because the doctors did not recognized the drug induced conditions, failure to monitor the patients during drug treatment, did not stopped the suspect medications or instituted counter-therapy to palliate the adverse drug reactions. Another reason is failure to communicate with the patients or their family members what is happening. Remember, an adverse drug reaction is often due to a product problem and not because of the doctor. But a drug safety problem can arise because of medication errors.
