Which class of drugs is commonly used off-label to delay ejaculation in premature ejaculation?

• A. PDE-5 inhibitors
• B. SSRIs
• C. Topical anesthetics
• D. Beta blockers

Answer: (B)

The main idea is that delaying ejaculation in premature ejaculation is most effectively achieved by increasing serotonin signaling in the brain. Selective serotonin reuptake inhibitors (SSRIs) do this by raising synaptic serotonin, which raises the threshold for the ejaculatory reflex and lengthens the time to ejaculation. Clinically, SSRIs such as fluoxetine, sertraline, paroxetine, and fluvoxamine are used off-label for this purpose, because their effect on ejaculation latency is well documented even though they’re not specifically approved for premature ejaculation in many places. They typically require several days to weeks to produce noticeable improvement, and patients may experience side effects like fatigue, GI upset, reduced libido, or anorgasmia. Other options don’t align as well with the goal. PDE-5 inhibitors improve erectile quality but don’t reliably prolong ejaculation. Topical anesthetics can delay ejaculation by reducing penile sensation but are a local treatment rather than a systemic drug class. Beta blockers are mainly used for performance anxiety rather than delaying ejaculation.
