Good detective work on your part, this could be important. However, switching antidepressant medication can be a tough thing, so be sure to consult an expert (psych?) before changing, tapering or stopping. Sometimes Prozac is given alongside the drug you're tapering to lessen the side effects of stopping an antidpressant.
I speak from experience. Not all antidepressants are alike, some are easier than others to come off of. I suppose you've seen this info?
Before having any kind of surgery involving the use of general anesthesia, tell your doctor or dentist that you are taking Anafranil. You may be advised to discontinue the drug temporarily.
When it is time to stop taking Anafranil, do not stop abruptly. Your doctor will have you taper off gradually to avoid withdrawal symptoms such as dizziness, fever, general feeling of illness, headache, high fever, irritability or worsening emotional or mental problems, nausea, sleep problems, vomiting.
Good luck with things,
