Pharmaceutical company offering bribes to doctors for fear that their products may not sell
Question

                I am a pharmacist working in one of the pharmaceutical companies as an advertising rep selling some of this company’s drugs. We give gifts to the doctors in the hospitals and private and public clinics, such as pens and watches on which is written the name of the product or the name of the distributing company. This is so that the doctor will prescribe this medicine or the medicines that we distribute to the patients. Most of the competing companies do that and do it to a great extent, such that we find ourselves forced to do it, otherwise our products will not sell. Hence patients fall victim to competition. What is the ruling on doing such things?.
Praise be to Allah.It is not permissible 
      to do such things, and it is regarded as a bribe which is haraam, because 
      it makes the employee limit himself to the company that has given him a 
      gift and ignore the other companies. This is consuming people’s wealth 
      unlawfully and harming others. What you must do is to avoid this and warn 
      others against it, because the Prophet  (peace and blessings of Allaah 
      be upon him) cursed the one who gives a bribe and the one who takes it. We 
      ask Allaah to keep us safe and sound. 

    From Fataawa al-Lajnah al-Daa’imah, 23/576 

    There is another wrongful action which the questioner refers 
    to, which is: 

    This action may also harm the patient, as the doctor may 
    prescribe this medicine to him, in the hope of getting a gift from the 
    company that produces it, even though some other medicine may be more 
    beneficial to the patient. 

    And Allaah knows best.
