Is sildenafil illegal in the US?

Are you wondering whether sildenafil is considered illegal in the United States? It's a common question, especially for those who are interested in understanding the legal status of this medication. While sildenafil is the active ingredient in prescription drugs like Viagra, which are used to treat erectile dysfunction, it's important to note that the non-prescription forms of sildenafil, often sold as generic Viagra or under other names, can be illegal. The Food and Drug Administration (FDA) has not approved these non-prescription forms for safety and effectiveness, and they may be contaminated with unknown ingredients or may not contain the active ingredient in the stated amount. It's always best to consult with a healthcare provider to obtain a prescription for sildenafil, and to ensure that you're using it safely and legally.
