What are over-the-counter options available for nicotine replacement therapy?

The choice of patches and lozenges as over-the-counter options for nicotine replacement therapy is accurate because both forms are readily available to consumers without a prescription. Nicotine patches work by delivering a steady, controlled amount of nicotine through the skin, helping to reduce withdrawal symptoms and cravings. Lozenge formulations also allow for nicotine absorption through the mucous membranes in the mouth, offering an alternative form that can be taken as needed when cravings arise.

Other options like nasal spray and inhalers are not over-the-counter; they generally require a prescription. They are considered prescription nicotine delivery systems that can help manage cravings but are not as accessible. Cravings suppressants, while they can aid in managing nicotine cravings, typically do not refer to a specific therapeutic category recognized within nicotine replacement therapies. Lastly, varenicline and bupropion, although effective smoking cessation medications, are also prescription drugs and not available to the public as over-the-counter treatments.

Thus, the patch and lozenge represent accessible, effective methods for individuals seeking to quit smoking through evidence-based nicotine replacement therapy.
