0 treatment(s) for Topical anaesthetics

Anaesthetics are used to prevent the nerve endings from emitting pain signals in a particular area during a surgical procedure. In minor cases involving the skin, such as during the administration of an injection or vaccination, wart removal or cryotherapy, a local anaesthetic may be distributed over the area of skin affected in order to help the process pass with the minimum amount of discomfort.

Insulin injections are a common fixture for many people living with type-1 diabetes, as are blood sugar tests, which are also undertaken with a needle. Vaccinations tend to be more often issued to those travelling abroad to a tropical location for a prolonged period; and to those who are susceptible to opportune infections such as flu.

People undergoing various cosmetic procedures, such as a tattoo, ear piercing or wart removal, may be required to stay seated and remain still for a period of time. When needles or incisions are being placed in the skin, this can understandably prove troublesome for many, and might also cause feelings of anxiety.

EMLA Cream is an example of a topically applied local anaesthetic which can help to desensitise an area of skin. It contains prilocaine and lidocaine.

These work by preventing chemicals from reacting with nerve endings under the skin, a process which plays an integral role in the transmission of pain signals to the brain. By interfering with this reaction, EMLA stops pain signals from being sent to the brain and reduce the amount of pain felt, creating numbness in the area of application.

Please note that we do not offer EMLA for topical anaesthetic purposes through our pharmacy at this time. If you are due to undergo one of the procedures above and require preparatory treatment, we recommend you speak to your doctor or pharmacist in person.

 

Creams and sprays are the typical form of issue for dermal anesthesia.

EMLA Cream is one such item.

How does it work?

EMLA contains prilocaine and lidocaine.

These ingredients function by preventing sodium from reacting with nerve endings under the skin to produce pain signals. When these pain signals are blocked from transmitting to the brain, the area of application becomes numb and a significant reduction in pain (if any whatsoever) is felt during the skin procedure which follows.

What are the side effects?

The side effects may vary depending on the method of application.

However, those more commonly associated with EMLA include tingling, a slight and temporary change in skin colour where the treatment is applied, or swelling.

Can I take it with other medications?

It depends mostly on which other treatments you are using. Tell your prescriber about any other medicines you are currently taking during consultation.

What’s the difference between the medications?

EMLA contains a topical anaesthetic. It is a cream, whereas other treatments may sometimes be given in the form of a spray.

Should I take EMLA Cream?

It depends on the procedure you are having done and where on the body it is taking place. EMLA Cream should only be used on the surface of the skin.

Ask your doctor or consult the product page for more information.

Are there different side effects?

The side effects may vary slightly according to the area where the cream is being used. More commonly, local anaesthetics when applied to the skin may cause tingling or slight and temporary paleness.

Is it right for me?

To see if this item is suitable for the anaesthetic purpose you require it for, we recommend you speak to your doctor or pharmacist in person.
