Ejaculating shortly after sexual activity begins and emotional or relationship distress are the main characteristics of PE.

Promescent spray is marketed toward people with premature ejaculation. It aims to delay ejaculation.

Online reviews of the Promescent brand are limited.

The company has a C+ rating on Better Business Bureau (BBB) with one complaint over the past three years. The company is not BBB accredited.

Promescent spray is an OTC desensitizing spray that may treat PE. It reduces the sensitivity of the penis to temporarily slow the onset of ejaculation.

Males use Promescent spray to prolong sexual intercourse or other types of sexual activity.

Each spray of Promescent contains approximately 10 milligrams (mg) of lidocaine, a topical anesthetic that has a numbing effect. Other delay sprays may contain different types of topical anesthetics in varying quantities.

Promescent and other delay sprays offer an alternative for those individuals who have not had success with psychological and behavioral treatments and do not want to take daily medication.

Promescent works by absorbing into the skin of the penis to reach the nerves that trigger ejaculation. By numbing these nerves, the spray can delay ejaculation.

Individuals should apply 3–10 sprays to the penis at least 10 minutes before beginning intercourse. This timing allows the product to absorb into the penis fully and take effect. It also ensures that the spray does not transfer to the person’s partner and reduce their sensitivity.

Individuals can adjust the dosage of Promescent to their individual preferences and sensitivity levels. The effects of the spray can last up to 60 minutes, depending on the dosage.

A person should wash the product off after intercourse or sexual activity.

According to anecdotal reports and a limited number of studies, Promescent appears to delay ejaculation effectively for some people.

A 2016 study consisting of 91 men indicates that Promescent increased the ejaculation latency time, or the time from stimulation to ejaculation, plus the quality of sexual experience, and perception of partner experience.

The study participants self-reported their experiences after 14 days of product use.

The average ejaculatory latency time increased from 6.81 minutes without Promescent spray, to 11.16 minutes following product use.

Both partners achieved orgasm approximately 65% of the time when using Promescent, compared with 44% when not using it.

The quality of sexual experience also improved significantly with the spray and continued to improve with each use.

Participants reported that the product was easy to apply.

A newer 2020 study investigated the effectiveness and tolerability of a 5% lidocaine spray in 150 people with lifelong PE. It reports that the spray significantly improved PE over a placebo.

The participants used either the spray or a placebo for 8 weeks. They applied it 10–20 minutes before intercourse.

An older study, published in 2003, reports similar findings for a topical spray, combining 7.5 mg lidocaine and 2.5 mg prilocaine, another type of local anesthetic.

Eleven males with PE completed the study. They applied the spray for 10–15 minutes before intercourse. On average, they reported that the spray increased ejaculation latency time from 1 minute and 24 seconds to 11 minutes and 21 seconds.

Participants also reported improved sexual satisfaction for both partners.

Promescent spray is a local treatment that a person applies only to the penis. Hence, it may carry fewer risks and cause fewer adverse reactions than systemic therapies for PE, such as medications.

However, there are some risks with its use, including rash, irritation, or itching in the person using it or their partner. If these symptoms occur, people should discontinue use and contact a doctor if they persist.

A person must not use Promescent spray on broken, irritated, or sensitive skin.

One 2018 study indicates that Promescent has a toxic effect on sperm, causing a reduction in sperm motility, forward progression, and viability. This effect could have implications for those trying to conceive.

Individuals must only use Promescent, and other delay sprays externally. They must not use them if they or their partner are allergic to lidocaine or topical anesthetics, or if the partner is pregnant.

​Those with liver problems should consult a doctor before using delay sprays.

Individuals must also seek medical attention if symptoms of PE persist. PE may indicate an underlying condition that requires treatment.

There are several products that aim to delay ejaculation on the market, including Promescent.

  • using the pause-squeeze technique during sexual activity
  • wearing condoms, which can decrease penis sensitivity


If stress or anxiety are contributing to PE, or if PE is negatively impacting relationships, then counseling may help. People may attend therapy alone or with a partner.

If a person has an adverse reaction to a PE treatment, such as a skin rash, they should stop using the product and seek medical advice.
