Local Anaesthesia
Containing Vasoconstrictor
Usually dentists prefer to administer local anaesthesia
with mepivacaine 3% without a vasoconstrictor.
However, according to the FDA classification,
mepivacaine, as well as articaine, are included
in Category C, which means that they are drugs that
should be used with caution while always weighing
the risks and benefits involved [16].
According to the FDA classification, lidocaine,
prilocaine, and etidocaine are included in Category
B, so the administered dose to pregnant women (as
well as to the general population) should be well
below the maximum recommended dose.
The above-mentioned local anaesthetics (lidocaine,
prilocaine, and etidocaine) may be combined
with vasoconstrictors and can be administered during
pregnancy. Their dosage is adjusted as follows:
maximum dose of lidocaine 500 mg, prilocaine 600
mg, etidocaine 400 mg.
