This was a retrospective study on recorded calls of DPICs in Iran from March 2012 to March 2013. Data consisted of general information; drug and poisoning information, medical history and also the distribution of a number of calls collected by DPICs in Iran. The centers received a total of 171769 calls. Most calls were made by the patients (56.1%) and then the patients’ relatives (38%). Also, 67% of the patients were determined as female. The calls mostly were focused on Adverse Drug Reactions (ADR) (15.3%), indications (14.0%) and drug evaluations (11.8%). Anti-infective agents, non-steroidal anti-inflammatory drugs (NSAIDs) and vitamins with 9.6%, 7%, and 6.8% frequencies were the highest frequently asked questions, respectively. Based on the results, patients do not receive enough information about their medications, from physicians and pharmacists. The DPICs have an important role to guide the people and provide the accurate drug and poison information and fill the absence of information that is not provided by medical staff. So, based on the important role of these centers, it is worth the Iran DPICs being introduced more to people, and we need more advertising around the country. https://acta.tums.ac.ir/index.php/acta/article/view/5206 https://acta.tums.ac.ir/index.php/acta/article/download/5206/4825
