Such drugs include atropine, propofol and Meperidine.
Meperidine is usually used only for a short time.
You will not be given Meperidine tablets or liquid for longer than is necessary.
When taking Meperidine by mouth, the dose should not be
repeated more frequently than every three to four hours.
If you are a driver, please be aware that Meperidine is likely to affect your reactions and ability to drive.
Meperidine can be taken by mouth as a tablet or liquid medicine,
but during childbirth it is more usually given as an injection.
If you are being given Meperidine for other types of pain(such as after surgery),
the injection can be repeated every three to four hours.
Although there are a number of narcotic analgesics, Meperidine(also known as pethidine) is
the one that has been traditionally used during childbirth, as its effects are shorter-lasting than some of the others.
If you are planning a trip abroad and
need to take Meperidine with you, you are advised to carry a letter with you from your physician
to explain why you have been prescribed it.
