2% Lidocaine and Epinephrine 1:100,000 Injection USP: Uses, Side Effects and Dosage

ABOUT THIS MEDICATION

BOUT THIS MEDICATION

WHAT THE MEDICATION IS USED FOR:

Lidocaine hydrochloride parenteral solutions are used to anesthetize part of the body for surgical operations and also for pain relief.

WHAT IT DOES:

Lidocaine hydrochloride parenteral solutions act by preventing the nerves in the injected area from transmitting sensations of pain, heat or cold. However, you may still experience sensations such as pressure and touch. In this way, the nerve(s) is anesthetised in the part of the body, which will be subjected to surgery. In many cases this means that the nerves to the muscles in the area will also be blocked, causing temporary weakness or paralysis.

WHEN IT SHOULD NOT BE USED:

Lidocaine hydrochloride parenteral solutions should not be used in patients who:

• are allergic to lidocaine, any other "-caine" type anesthetics, or any of the non-medicinal ingredients in the product (see

NONMEDICINAL INGREDIENTS below)

• are allergic to sodium metabisulfite
• are allergic to methylparaben (preservative used in some solutions) or PABA

Lidocaine hydrochloride parenteral solutions containing methylparaben should not be used for epidural or spinal anaesthesia.

Because of the potential for irreversible joint damage, pain following joint surgery should not be managed

by infusing Lidocaine hydrochloride parenteral solutions into the joint (i.e. by use of a post-operative “pain pump”).

WHAT THE MEDICINAL INGREDIENTS ARE:

lidocaine hydrochloride 1% and 2%.

lidocaine hydrochloride 2% and epinephrine 0.010 mg/mL (1:100,000).

NONMEDICINAL INGREDIENTS:

Lidocaine hydrochloride parenteral solutions contain water for injection and may contain sodium chloride, sodium hydroxide and/or hydrochloric acid. Multidose vials contain methylparaben.

Lidocaine hydrochloride parenteral solutions with epinephrine contain citric acid, methyl paraben, sodium chloride, sodium hydroxide, sodium metabisulfite and water for injection.

Check with your doctor if you think you may be sensitive to any of the above ingredients.

WHAT DOSAGE FORMS IT COMES IN:

Lidocaine hydrochloride Parenteral Solutions are available in plastic ampoules, single use and multidose glass vials, and glass ampoules.
