Who is permitted to use hypodermic syringes and needles without a prescription?

The ability to use hypodermic syringes and needles without a prescription is typically granted to individuals who are licensed healthcare providers or have specific qualifications in their field. Dentists and medical interns are included in this category because they are trained medical professionals who require access to these tools for patient care.

Dentists, as licensed practitioners, are authorized to administer injections for various dental procedures. They have the necessary training to handle hypodermic syringes and needles safely and effectively. Similarly, medical interns, although still in training, are often permitted to use these instruments under the supervision of licensed physicians as part of their educational process.

Other options, such as licensed pharmacists and qualified veterinarians, may also have specific permissions regarding the use of hypodermic syringes and needles, but those permissions are generally regulated under different contexts and typically do not include unrestricted use without prescriptions in the same manner as dentists and medical interns. Commercial suppliers and dealers are generally focused on the distribution and sale of medical supplies rather than their direct use in clinical settings. Thus, the correct answer reflects both the context of practice and the training involved for the permitted use of hypodermic syringes and needles.
