Delay spray
Updated over a week ago

How the delay spray works

The delay spray (lidocaine) is a local anaesthetic which is used to reduce the sensitivity of the penis just before intercourse. The delay spray contains 15% lidocaine and is an unlicensed medication - you can find more information on unlicensed medications here

The reduction in sensitivity helps to delay ejaculation in cases of over-rapid or premature ejaculation. It should not impact the amount of sexual pleasure you feel during sex.

The delay spray should not be taken if

  • You or your partner are allergic (hypersensitive) to Lidocaine

  • You or your partner are allergic (hypersensitive) to other local anaesthetics

  • Your partner is pregnant

Do not use the Delay spray on broken or inflamed skin, and never spray near the eyes or nostrils.

Lidocaine spray may not be suitable for you if you have, or have ever had liver or kidney problems. If this is the case, please ask your doctor before using the spray.

High blood levels of Lidocaine can cause interactions with other medicines. Although this is unlikely to occur with the low levels absorbed you should ask your doctor or our clinical team for advice before using the spray if you are taking other medicines. Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines or herbal therapies obtained without a prescription.

Lidocaine spray should not be used by elderly men.

Taking the Delay spray correctly

Using the spray is simple. Apply 2-5 sprays to the head and shaft of your penis and leave it for five to fifteen minutes to give it time to absorb into your skin. You can do this before or after getting an erection. Before having sex, be sure to wipe off any excess spray –either using a wet towel or by quickly rinsing. This is to make sure that you minimise the transfer of the spray to your partner. In any case, we always recommend using a condom.

As long as you don’t exceed 2-5 sprays, the amount of lidocaine in the Delay spray will not numb your penis completely – it will only reduce your sensitivity, ultimately giving you more control over when you ejaculate. You can, however, experiment with the dosage and find the right one for you.

Lidocaine spray is safe to use whilst wearing regular latex condoms. However, it could cause condoms made of polyurethane-based materials to wear down so these types of condoms should be avoided.

You should not take exceed the maximum dose of 15 sprays within 24 hours.

Possible side effects

The most common side-effects are a stinging or burning sensation, temporary numbness and loss of erection, although this last one could be due to the time spent waiting for the spray to work. Less commonly you could experience redness, irritation or itching. If you experience any of these, you should stop using the spray. If you are worried about any side-effects, speak with our clinical team or your doctor.

When your spray arrives, which should be within the next 48 hours, please make sure to read the patient information leaflet enclosed. It contains other important safety information as well as a complete list of possible side effects.
