1.What LIGNOKENT is and what it is used for_

LIGNOKENT is given by injection to cause loss of feeling

before and during dental procedures.

It contains two active ingredients:

•    lidocaine hydrochloride, a local anaesthetic, which prevents pain,

•    adrenaline tartrate, a vasoconstrictor which makes the effect last longer. Adrenaline narrows the blood vessels at the site of injection, which keeps the anaesthetic where needed for a longer time. It also controls the bleeding during the surgery.

LIGNOKENT is for adults, children and adolescents.

Only a dentist can administer this product.

2.Before you use LIGNOKENT_

Do not use LIGNOKENT

•    if you are allergic (hypersensitive) to one of the active ingredients (lidocaine hydrochloride or adrenaline tartrate) or to any of the other ingredients (refer to section 6)

•    if you are allergic to local anaesthetics called amide type anaesthetics,

•    if you are asthmatic or have suffered difficulty with your breathing as a result of taking medicines which contain ingredients called sulphites or metabisulphites,

•    if you have a high blood pressure (arterial hypertension),

•    if you have particular heart or blood vessels disease (coronary or valvular cardiac disease),

•    if you are taking or have taken medicines for depression in the last two weeks,

Take special care with LIGNOKENT
