Lidocaine cream is a topical anesthetic that numbs the applied area by blocking nerve signals in the skin and surrounding tissues. This temporarily prevents pain signals from reaching the brain. Available in creams, gels, and sprays, it can alleviate discomfort from minor skin irritations or before certain procedures. It is a common choice for localized numbing.
Primary Applications for Penile Use
Lidocaine cream is primarily used on the penis to manage premature ejaculation (PE). By reducing sensitivity in the glans (head) and shaft, it helps delay ejaculation, allowing for longer sexual activity. Studies show topical anesthetics like lidocaine effectively increase intravaginal ejaculatory latency time (IELT), which is the time to ejaculate during intercourse. For example, a 2021 study found that 5% lidocaine spray significantly improved PE symptoms and increased IELT.
This reduced sensitivity helps individuals avoid overstimulation, extending sexual encounters. Beyond PE, lidocaine cream can also offer temporary relief from minor skin discomforts on the penis, such as mild irritation or superficial scrapes.
Safe Application Guidelines
To use lidocaine cream on the penis, apply a small, pea-sized amount to the glans and frenulum. Gently spread a thin layer. The cream usually starts to work within minutes, with its full numbing effect appearing within 10 to 30 minutes.
Before sexual activity, thoroughly wash off any excess cream to prevent transfer to a partner, which could cause unwanted numbness. Perform a patch test on a small skin area beforehand to check for sensitivity or allergic reactions. Applying the cream more than 30 minutes before sex might lead to excessive numbness and potentially affect erection quality.
Potential Side Effects and Safety Precautions
Using lidocaine cream on the penis can lead to side effects, with temporary numbness being the most common. This numbness can sometimes exceed the desired level, potentially affecting erection or orgasm. Other localized reactions may include mild irritation, burning, stinging, redness, or itching at the application site. These effects often subside as the body adjusts.
More serious, though rare, concerns involve systemic absorption into the bloodstream, especially with excessive use, application over large or broken skin, or if covered. Symptoms of systemic toxicity can include sudden dizziness, drowsiness, confusion, blurred vision, ringing in the ears, or unusual temperature sensations. Allergic reactions, such as hives, difficulty breathing, or swelling of the face, lips, tongue, or throat, require immediate medical attention.
Avoid using the cream on broken, irritated, or infected skin, as this increases absorption and the risk of adverse effects. If side effects persist, worsen, or if any severe reactions occur, seek medical advice.
