KY Duration Spray Ingredients

Here is a list of the active and inactive ingredients used in K-Y delay spray:

Active Ingredient

Lidocaine (9.6%) is the active ingredient in K-Y Duration Delay Spray. It is a local anesthetic approved by the FDA for use in male genital sprays with a restriction of 10 mg per spray (maximum). KY Duration spray follows FDA instructions, and a single spray (or jet) contains approximately 10 mg, so you can use it with peace of mind.

So, what does lidocaine do?

Lidocaine numbs your penis since it is a topical anesthetic. The intensity of numbness depends on several factors including the number of sprays, skin type, etc. Some men feel completely numb with a few sprays while others only feel a reduction in sensitivity.

The numbing effect usually starts within a few minutes. It is recommended to wait 5-15 minutes and let the spray absorb completely for better efficacy. You can proceed with sexual intercourse when you start feeling numbness.

Waiting too long will make your penis completely numb and you will lose sensation. This makes it hard to maintain an erection. So, it’s important that you do not lose sensation and feeling completely in your penis after the spray.

Inactive Ingredients

Here is a list of the inactive ingredients used in KY Duration Spray:

  1. Ethoxydiglycol: It is an organic, colorless compound used as a solvent in skin care products. It helps improve the functioning, texture, and penetration of the KY Duration Delay Spray
  2. Isopropyl Myristate: It is a moisturizer that is used in a wide range of topical medications to improve absorption of the products in the skin 
  3. Stearic Acid: It is a fatty acid that helps products maintain their shape and structure. It also stabilizes the products it is mixed into
  4. Fragrance: The KY Duration Spray uses fragrance to cover the smell of lidocaine. The fragrance isn’t noticeable, however, and you will still feel a subtle smell of lidocaine that isn’t too pleasing.

KY Duration Spray Side Effects

Here is a list of the rare side effects of the K-Y Duration Delay Spray:

  • Skin irritation, itching, blistering, redness, or dryness
  • Skin rash
  • Cough and fever
  • Swelling on genitals
  • Heartbeat issues
  • Tiredness and fatigue
  • Joint and muscle pain
  • Vision and voice issues.

There are other rare side effects that are associated with inactive ingredients. These include:

  • Drowsiness
  • Headache
  • Nervousness
  • Skin issues.

If you or your partner are allergic to any of the ingredients, don’t use the spray.

All the side effects are rare which means the percentage of people who are likely to suffer from any of these side effects is negligible (between 0.1% and 0.01%). In case of any negative symptoms, stop using the spray and consult a doctor immediately.

Safety Instructions

There are certain conditions when you should not use the K-Y Spray:

Step #1: Wash Your Penis

Wash your penis with water to remove debris for the effective application of the KY Duration spray. You don’t have to wash your penis right before sex, but if you have washed it 3-4 hours before sexual intercourse, it’d be fine.

Step #2: Shake KY Duration Spray Bottle

Shake the KY Duration delay spray bottle well before use. It ensures that all the spray is mixed up eventually and its active ingredient doesn’t just keep sitting at the bottom. Shaking the bottle 2-3 times is a good technique to make sure lidocaine and all the other ingredients are mixed properly.

Step #3: Apply KY Duration Spray

Keep the spray bottle 10 cm away from your penis (this is approximately the same distance you use for perfumes or body sprays). Apply 3-10 sprays on your penis head and shaft. Don’t exceed 10 sprays in a single go.

You can use KY Duration spray on your penis before or after it is erect. You don’t have to wait for an erection to apply the spray.

Step #4: Spread the Spray

Once you have sprayed your penis head and shaft, gently massage your penis to spread the spray evenly. Focus on your penis head as it is the sensitive part of your penis.

Step #5: Let the KY Duration Spray Absorb

Wait for 5-15 minutes and let the spray absorb completely. Normally, the KY Duration Spray absorbs in less than 5 minutes if you massage the penis head and shaft gently.

Step #6: Wash Your Penis

Once the spray is absorbed and you’ll feel numbness, you need to wash your penis.

This is important as washing will remove KY Duration Spray residue from your penis and it won’t pass onto your sex partner. Even if the spray is absorbed completely and you don’t see any deposits, you still need to wash your penis with water before sexual intercourse.

Step #7: Sexual Intercourse

Now you are ready for sexual intercourse.

KY Duration Spray should only be used for vaginal intercourse. It isn’t recommended for oral sex, even if you have washed your penis. Because it might numb your partner’s mouth. Washing your penis after applying KY Duration spray doesn’t mean it won’t pass the numbness to your partner, it still might. 

If you are into oral sex, make sure you apply KY Duration Spray on your penis after oral sex.

Step #8: Wash After Sex

After sexual intercourse, wash your penis with soap to remove the residue of the spray.
