Pharmacists, Drs, Nurses.. is it true that dental Lidocaine causes a drug reaction in people who take inderal?

Answer:
Yes, it is a know drug interaction and you should have been counseled when you got the prescription about that and a whole list of drugs you should not take in conjunction with the Inderal. Part of the reason it is contraindicated with lidocaine is because it is a beta blocker, which affects not only the blood pressure but the heart rate and rhythm. Lidocaine is a cardiac drug used to correct rapid heart rhythms, such as ventricular tachycardia. The two would tend to argue with one another. Any time you have dental work, you should let the dentist know you are taking inderal beforehand. There are other things he can use for local anesthetic that will not interact. Something else common, you need to avoid is Motrin (ibuprofen), Naprosyn (naproxen sodium), and other non-steroidal anti-inflammatory drugs. If you don't have the no-no list, get one from the pharmacy. It's that important.

I will have to check out whether there is any DIRECT interaction between the two medications....I'm not aware of any.Lidocaine is used to manage certain cardiac problems (i.e. arrest, arrhythmnias), it is used INTRAVENOUSLY in these instances and at much higher doses than your dentist gives you. Epinephrine is also used to manage some of these same cardiac events. Inderal would directly counteract epinephrine. Epinephrine is commonly added to lidocaine for dental and minor surgical procedures. Perhaps that is the 'interaction' you are referring to? Naturally, some of the lidocaine that is injected into your mouth does make it into your system. Anxiety and agitation can be caused by this. If you are being treated for anxiety, that would be a bit of a problem.
