Which form of nicotine replacement therapy is prescription only?

Nasal spray is a prescription-only form of nicotine replacement therapy because it is delivered in a way that allows for rapid absorption of nicotine through the nasal membranes. This method may have a higher potential for misuse and side effects compared to other forms of nicotine replacement therapy, such as gum, patches, or lozenges, which are available over the counter.

The nasal spray can provide quick relief from cravings and withdrawal symptoms, making it an effective option for some individuals. However, due to these factors, it is regulated and requires a prescription, ensuring that a healthcare provider oversees its use to manage any potential risks or side effects properly. This contrasts with other forms of nicotine replacement, which are typically safer and can be used without the need for medical supervision.
