Benzocaine vs Lidocaine for Premature Ejaculation: Sprays and Wipes

This guide compares the two on what the rule allows, how each is used, what studies found, the label warnings, and prices where a seller publishes one. We list prices only, never doses. Prescription options for PE are priced on our PE price page.

What the FDA rule allows

Most delay sprays and wipes sold in US stores follow one FDA rule, called a monograph. A monograph lists the ingredients an over-the-counter drug may contain and what its label must say. For this group, the rule names two ingredients:

• "Benzocaine, 3 to 7.5 percent in a water-soluble base."
• Lidocaine "in a metered spray" with a fixed amount per spray.

(21 CFR 348.10, eCFR, read 14 November 2026)

The same rule sets what the label may claim. One allowed claim is "Helps in the prevention of premature ejaculation." Another is "For temporary male genital desensitization, helping to slow the onset of ejaculation." So these are real, FDA-regulated drugs, sold without a visit.

Benzocaine vs lidocaine side by side

Both work the same way. MedlinePlus, the US National Library of Medicine's health site, puts it simply: "Decreased feeling in the penis may delay ejaculation." (MedlinePlus: premature ejaculation, read 14 November 2026)

Delay spray: lidocaine

A male delay spray, also called a penile numbing spray, is usually lidocaine. The spray pump releases a set amount each press, which the rule requires. Promescent's spray label lists its purpose as "Anesthetic", meaning a numbing drug, and its use as "Helps in temporarily slowing the onset of ejaculation." (DailyMed: Promescent spray label, read 14 November 2026)

The label tells you to rub it in and wash it off after sex. Its warnings say not to use it if "You or your partner are allergic to lidocaine or topical anesthetics" or if "Your partner is, or may be pregnant." It also says to ask a doctor first if "You have liver problems."

What sprays do well: you can adjust how much you use, within the label's limit, and the spray dries into the skin.

Desensitizing wipes: benzocaine

Desensitizing wipes are usually benzocaine. Each wipe is pre-soaked, so there is nothing to measure. Promescent's wipes list "Benzocaine 7% Male Genital Desensitizer" as the active ingredient (DailyMed: Promescent Delay Wipes label, read 14 November 2026).

Ro sells benzocaine wipes as Roman Swipes. Its plans and per-wipe price are in our Roman Swipes cost guide. What wipes do well: they are easy to carry and need no pump.

Do numbing products work?

A 2023 review pooled 11 trials with 2,008 men. It found that lidocaine and other numbing products "were significantly more efficient than a placebo" (Cureus, 2023). A placebo is a dummy treatment, like a sugar pill. The authors concluded that "topical anesthetics increase IELT in men with premature ejaculation more effectively than placebo". IELT is the time from penetration to climax.

Most trials tested lidocaine or lidocaine mixes. We found no head-to-head trial of benzocaine against lidocaine, so neither can be called the better one on the evidence.

The American Urological Association (AUA) puts numbing products among its first choices. Its guideline says clinicians "should recommend daily SSRIs; on demand clomipramine or dapoxetine (where available); and topical penile anaesthetics as first-line pharmacotherapies in the treatment of premature ejaculation." (AUA guideline: disorders of ejaculation, read 14 November 2026) First-line means the first drugs to try.

Warnings for both

The FDA rule requires the same warnings on every product in the group. The label must say: "Premature ejaculation may be due to a condition requiring medical supervision. If this product, used as directed, does not provide relief, discontinue use and consult a doctor." It must also say "Avoid contact with the eyes." (21 CFR 348.50, eCFR)

The rule also covers partners: "If you or your partner develop a rash or irritation, such as burning or itching, discontinue use." Numbing can pass to a partner if the product is not washed off or absorbed, which is why labels say to wash after sex.

Prices

Ro publishes its Swipes prices; our Roman Swipes cost guide lists each plan with its read date. Promescent's own store did not load for our reader on 14 November 2026, so we show no Promescent price; check its site or a drugstore. Drugstores stock similar sprays and wipes under several brands.

If numbing is not enough, prescription options include SSRI antidepressants, which are not approved for PE but are prescribed for it, and compounded combinations. Our PE pills cost guide prices them, and our list of the best PE programs ranks the sellers.
