alert than they are normally. This is more likely to happen when you begin
to take it or when you increase the amount of medicine you are taking. Make sure you know how you react to this medicine before you
drive, use machines, or do anything else that could be dangerous if you are
dizzy or not alert
.
Dizziness, lightheadedness, or fainting may occur,
especially when you get up from a lying or sitting position. Getting up slowly
may help
, but if the problem continues or gets worse, check with your
doctor.
The dizziness, lightheadedness, or fainting is also more likely to occur
if you drink alcohol, stand for a long time, exercise, or if the weather is
hot. While you are taking this medicine, be careful in
the amount of alcohol you drink. Also, use extra care during exercise or hot
weather or if you must stand for a long time
.
Before having any kind of surgery (including dental surgery) or emergency
treatment, tell the medical doctor or dentist in charge
that you are using this medicine

Phenoxybenzamine may cause dryness of the mouth, nose, and throat. For
temporary relief of mouth dryness, use sugarless candy or gum, melt bits of
ice in your mouth, or use a saliva substitute. However, if dry mouth continues
for more than 2 weeks, check with your medical doctor or dentist. Continuing
dryness of the mouth may increase the chance of dental disease, including
tooth decay, gum disease, and fungus infections.
