There are many sexual performance products on the market. However, the industry is saddled with transparency issues and false promises, making it tough to separate the quality products from one that aren’t safe to use.

Promescent is a company that makes sexual health products. While the company overall has some transparency issues — especially when it comes to their line of oral supplements, which we don’t recommend — their Delay Spray should be safe when used as directed.

This article takes a closer look at the company and its spray designed to delay ejaculation.

Promescent Delay Spray is a sprayable, lidocaine-based product designed to help delay ejaculation.

Some research suggests that lidocaine, the main active ingredient of this spray, effectively prevents premature ejaculation (PE).

A randomized, single-blind placebo-controlled trial from 2020, found that a 5 percent lidocaine spray, applied 10 to 20 minutes before sexual activity, reduced instances of PE. The Promescent spray has 10 mg of lidocaine per spray.

It’s important to point out that the participants in the study, 150 in total, experienced PE but otherwise had typical erections.

Lidocaine and lidocaine-containing products are not designed to treat erectile dysfunction (ED). With ED, a person cannot get or maintain an erection.

By producing a numbing sensation in sensitive parts of the penis, the spray reduces the likelihood of experiencing PE. If there’s less feeling in the penis, a person can last longer during sex.

The company recommends applying the spray to the shaft and head of the penis 10 minutes before sex. The recommended dosage is at least three sprays, but you shouldn’t exceed 10 sprays.

After sex, you should wash off the spray.

Topically applied lidocaine is generally safe to use. But there are some potential risks involved in using a spray like Promescent Delay.

Allergic reactions

Some people may be sensitive or allergic to certain ingredients. If you or your partner has an allergy to lidocaine, don’t use Promescent Delay Spray.

Similarly, inactive ingredients can also cause irritation. For example, the spray contains fragrance, which may cause a reaction in some people.

Effects on sperm

There’s some evidence that lidocaine may be toxic to sperm.

A 2018 lab study found that Promescent significantly reduced sperm motility and viability compared to control samples. However, more research is needed to confirm these results.

That said, the spray’s label still recommends not using the spray if you or your partner is or could be pregnant.

Other warnings

Other warnings include:

  • Talk with your doctor before using the spray if you have liver problems.
  • Don’t use the spray on broken or sensitive skin.
  • Stop using the spray if irritation or a rash develops.

If the spray doesn’t seem to work, talk with your doctor.

Additionally, be careful with your application. Applying the product correctly ensures that it gets fully absorbed and won’t produce a numbing effect for your partner.

Some users say that Promescent Delay Spray works.

Additionally, several studies have looked at the effectiveness of lidocaine for delaying ejaculation. The results indicate that a lidocaine-based spray is an effective treatment for PE.

A 2016 study looked specifically at Promescent’s effectiveness in men with PE. The study results suggested the spray helped reduce PE and significantly improved the participant’s quality of sexual experience. But the study’s sample size was relatively small, with only 91 participants.

A 2020 study found that, compared with oral dapoxetine, topical lidocaine is more effective at treating lifelong premature ejaculation.

Another 2020 study looked at the effects of lidocaine spray for PE and found that those in the treatment group experienced positive results.

Overall, Promescent’s reputation is fairly positive. However, they don’t have a rating with the Better Business Bureau (BBB). Currently, Promescent’s parent company, Absorption Pharmaceuticals, LLC, has a single customer review on the BBB website and no complaints.

The company claims the products are made in a cGMP-compliant facility, but there’s no third-party certification to confirm this.

Customer reviews seem to be mostly positive. Reviewers on third-party sites, like Amazon, say that the spray is fast-acting, effective, and travel-friendly.

A handful of reviewers complain about the overwhelming scent. One reviewer also notes that, even when waiting the full 10 minutes before having sex, the spray also numbed his partner.

A few reviewers also say that the spray has no effect. Additionally, a few reviewers say they experienced an allergic reaction to the product.

How many sprays of Promescent Delay Spray should you apply?

Promescent recommends using at least three sprays. Some people may need additional doses to experience adequate numbing effects.

Promescent recommends not exceeding 10 sprays at a time.

How long does Promescent Delay Spray last?

According to Promescent, the Delay Spray may last up to an hour, depending on how much you apply.

Does Promescent Delay Spray numb your partner?

According to Promescent, the spray isn’t supposed to numb your partner, as long as you use it as directed.

While Promescent Delay Spray seems to be an effective product for preventing PE, we’re wary about recommending a minimally transparent company as a whole.

Still, studies suggest that lidocaine-based sprays can help delay ejaculation.

Before trying any numbing product, read the ingredient list and perform a patch test on your skin before applying it to the sensitive genital area.

Don’t use this type of product if you have ultra-sensitive skin or allergies to lidocaine or any listed non-active ingredients.

When in doubt, talk with your doctor.
