Delay Spray (2026): Does Lidocaine Spray Work for Premature Ejaculation?

A delay spray is a topical anesthetic, most often lidocaine, sprayed on the penis before sex to reduce sensitivity and delay ejaculation. The FDA calls these products male genital desensitizers. Under the federal OTC monograph (21 CFR Part 348), a product can be sold without a prescription if it uses one of two ingredients at a set strength:

• Lidocaine in a metered spray delivering about 10 mg per spray
• Benzocaine at 3% to 7.5% in a water-soluble base

The monograph also fixes the label wording. Approved indications include "helps in the prevention of premature ejaculation" and "for temporary male genital desensitization, helping to slow the onset of ejaculation." If a product's claims go well beyond that, be skeptical.

Yes, for many men. The AUA/SMSNA Disorders of Ejaculation guideline (2020) lists topical penile anesthetics among the first-line pharmacotherapies for premature ejaculation, as a strong recommendation based on Grade B evidence. Reduced sensitivity raises the threshold for ejaculation, which gives you more time.

Results vary by person and by how you use it. Too little spray may do nothing. Too much, or not wiping off the excess, can numb you to the point of losing your erection or pleasure, and can numb your partner. The guideline also says combining behavioral and medication approaches may work better than either alone.

Lidocaine is the most common delay spray ingredient. It blocks nerve signals in the skin for a short time, which dulls sensation without affecting erections directly. The monograph directions for lidocaine sprays are: apply 3 or more sprays, not to exceed 10, to the head and shaft of the penis before intercourse, or use as directed by a doctor, and wash the product off after intercourse.

Brands describe strength in different ways. The monograph sets about 10 mg per spray; some brands list a percentage instead. Dynamo Delay, for example, lists 13% lidocaine on its product page. Read the Drug Facts panel on any product you buy, and stay within its maximum number of sprays.

Start low, wait, wipe, and wash. The step-by-step list on this page follows the monograph and Dynamo's published directions. Try it on your own first, not before sex with a partner, so you learn how many sprays work for you without surprises.

• Spray only the head and shaft of the penis, never inside the urethra.
• Wait 5 to 10 minutes for it to absorb, per Dynamo's directions.
• Wipe off any excess before contact.
• Wash it off after sex.
• Keep it away from your eyes, as the monograph warns.

Numbing spray can transfer to your partner, so wipe off the excess before contact and wash it off after sex. Transfer can numb your partner's genitals or mouth, and the monograph tells users to stop if either partner develops a rash or irritation such as burning or itching.

A condom can help in two ways: it limits transfer, and some men find a condom alone reduces sensation enough. If you use both, let the spray absorb and wipe off the excess before putting the condom on, and check the condom maker's guidance on use with topical products.

The most common problems are too much numbness, a softer erection from reduced sensation, and skin irritation in either partner. Stop use if you or your partner get a rash, burning or itching, as the FDA monograph label requires.

• Do not use one if you are allergic to lidocaine, benzocaine or other local anesthetics.
• Do not use on broken or irritated skin.
• Ask a pharmacist or doctor first if your partner is pregnant or if either of you has sensitive skin conditions.
• Do not exceed the label's maximum number of sprays.

Dynamo Delay and Promescent are two of the best-known OTC delay sprays. Dynamo Delay (card above) lists 13% lidocaine, monograph-matching directions, a $17.99 single bottle and a 30-day money-back guarantee. Promescent is another widely sold delay spray; its homepage did not list the active ingredient when we checked on October 30, 2026, so read the Drug Facts panel on its packaging for the ingredient, strength and directions.

Whatever brand you choose, look for a Drug Facts label that names lidocaine or benzocaine and calls the product a male genital desensitizer. That is the sign it follows the federal monograph.

See a clinician if delay sprays do not help, if premature ejaculation started suddenly, or if you also have trouble getting or keeping an erection. The AUA/SMSNA guideline lists daily SSRIs and on-demand clomipramine as other first-line medications, which require a prescription, and recommends combining medication with behavioral approaches when helpful.

Some men who think they have PE actually have ED, and rush to finish before the erection fades. In that case, treating the erection problem helps more than numbing.
