Local Anaesthetic with Vasoconstrictor
Last reviewed June 2026
Who is this for?
This is an injectable combination of two drugs — lidocaine (a local anaesthetic that numbs a specific area of your body so you don't feel pain) and epinephrine (adrenaline, which tightens blood vessels to keep the numbing effect in that area longer and reduce bleeding).
Blocks voltage-gated sodium channels in nerve cell membranes, preventing depolarization and nerve impulse transmission; epinephrine acts as a potent alpha-1 and beta-2 adrenergic agonist, causing vasoconstriction to prolong local anaesthetic duration and reduce systemic absorption.

This is not a drug you take yourself — it is given by injection by a doctor, dentist, or trained health worker only. The dose depends on the type of procedure and the area being numbed. It is usually injected directly into or near the area that needs to be numb.
This does not apply because this drug is given once by a doctor or dentist during a procedure — it is not something you take on a regular schedule at home.
This injection should only be given by a trained doctor, dentist, or health worker in a proper clinical setting — never by an untrained person. Make sure the product is from a trusted pharmacy — in Nigeria, you may see it sold as Alphacaine 100 Injection. If you notice any unusual swelling, difficulty breathing, or fast heartbeat after receiving this injection, alert your doctor immediately.
If you are taking drugs for depression (like amitriptyline or imipramine), tell your doctor because they can cause dangerous increases in blood pressure when combined with epinephrine. If you are on heart or blood pressure medicines (like propranolol or atenolol), let your doctor know as these can interact. Avoid combining with other local anaesthetics as this increases the risk of side effects.

Is it safe to take Lidocaine with your other drugs?
This injection can be used during pregnancy and breastfeeding when medically necessary, but always inform your doctor or dentist that you are pregnant or breastfeeding so they can adjust the dose and take extra care.
Store below 25°C in a cool, dry place away from direct sunlight and heat — Nigerian weather can be very hot so avoid storing near windows or in cars. Do not freeze. Keep out of the reach of children. Once opened, any unused portion should be discarded.
