What does PF in Lidocaine PF stand for? ( 3+ ways to ensure safe and effective use)

What does PF in Lidocaine PF stand for?

PF in Lidocaine PF stands for ‘Preservative-Free’. It is a form of Lidocaine formulation that does not contain any added preservatives. Lidocaine is a local anaesthetic that is commonly used to numb or desensitize the area for the purpose of relieving pain (1).

Preservatives are generally added to medications to enhance and maintain their purity by preventing microbial contamination. However, some people could be allergic to preservatives and using regular Lidocaine can trigger unwanted reactions.

In such cases, Lidocaine PF is considered a safe and effective alternative, as it prevents an acute allergic reaction. However, Lidocaine PF should never be used without a doctor’s supervision.

What are the uses of Lidocaine PF?

Lidocaine PF is available as an injectable solution and a topical gel.

  • Lidocaine PF injectable solution is used to numb an area of the body locally before any surgical procedure- like dental surgeries (Tooth extraction, dental filling, root canals, etc), ingrown toenail removal surgery, etc.
  • Lidocaine PF topical gel is applied to the skin or mucous membranes to numb the area before minor superficial procedures or to relieve pain.

Lidocaine PF can also be used in combination with Epinephrine, a vasopressor that works by neutralising the vasodilatory effects of Lidocaine. However, it should not be used unless recommended by a healthcare provider. It is also important to make sure that you are not using expired Lidocaine PF gel on your skin.

This is because Lidocaine PF does not have preservatives to control bacterial contamination and it has a shorter expiration date as compared to the regular Lidocaine formulations, which have longer expiration dates. This is because preservatives prolong the shelf life of a product by keeping microbial contamination at bay.

Important points to know when using Lidocaine PF

As discussed earlier, Lidocaine PF should only be used under a doctor’s supervision. The use of injectables should be more carefully carried out, as they are directly administered into the bloodstream. Some important points to know before going for a Lidocaine PF injection are:

  • Lidocaine PF injection must be administered by a trained healthcare professional such as a nurse, or a doctor.
  • To reduce the danger of infection, Lidocaine PF injection should be administered using sterile techniques and the site of injection should be thoroughly cleaned with a suitable antiseptic solution.
  • The precise injection site should only be determined by a doctor. Lidocaine PF can be injected intravenously, intramuscularly, or subcutaneously.
  • The dose of Lidocaine PF should be properly calculated, according to the intended use and overall condition of the patient.
  • Patient monitoring is important, following the injection, to look out for any immediate adverse reactions.

Final words

To sum up, Lidocaine PF is a preservative-free Lidocaine, specifically manufactured for individuals who are sensitive or allergic to various preservatives. Just make sure you don’t use any of the Lidocaine PF formulations without consulting your doctor first.
