In this article we're going to discuss the possible dangers and side
effects of antihistamines and what people should be aware of when taking
antihistamines to treat their allergies.

For the most part, antihistamines are safe. Having said that,
antihistamines can have side effects which, if the antihistamine is not
properly administered, can be serious.

The truth is, all medications have side effects. Some are mild, as in
the case of an aspirin, unless you have stomach ulcers or aspirin
sensitivity and others are more serious such as the side effects from
chemotherapy, but for the most part, antihistamine side effects are
fairly mild. The newest antihistamines are probably about the safest
medications that there are. But there are differences between the
various antihistamines and their side effects.

The older antihistamines have the most serious side effects. Because
technology wasn't where it is now, older antihistamines can make you very
sleepy, even to the point of falling asleep behind the wheel of a car.
The harsh truth is, antihistamines have the same effect on your brain as
alcohol. If you've been keeping up with the latest news you'll notice
that people seem to be driving around in a drug induced haze. This is
becoming a very serious problem in itself as there are no laws against
driving while under the influence of prescription medication. That is
most likely going to change very soon. According to experts, there is no
doubt in their mind that older antihistamines can cause traffic

But that isn't where the effect of older antihistamines ends. They also
affect learning and exam performance. Studies show that children with
allergies who go to school after taking an antihistamine have poorer test
scores than children who are not on antihistamines.

Another problem with older antihistamines is that one of the side effects
is that people who use them sometimes have difficulty in passing water.
or have increased pressure in their eyes. These symptoms, however, are
very rare.
With the newer antihistamines, most, if not all of these side effects are
a thing of the past. We have certainly come a long way. Therefore it is
no longer necessary to use the older antihistamines.

Many people ask, how do we know the newer antihistamines are better?
Actually, there are studies that clinically show that they are.

For starters, road safety studies were done. Two control groups were
used. The one group was given older antihistamines and the other group
was given the newer improved antihistamines. The results were
staggering. The reaction time of the old antihistamine group was slower,
their turning was more erratic, their attention was poor and in general
they did not drive as skilfully. In some cases their driving was so bad
and so dangerous that the test itself had to be stopped.

Another study was done on children going to school. Two control groups
were again set up. The group that was given the older antihistamines had
much lower test scores, sometimes as much as 20 to 30 points lower. Many
of the students couldn't even finish their exams.

The only downside of the newer antihistamines, and for that matter any
treatment of this sort for allergies, is that they are not a cure and
over time a person can build up a resistance to a particular
antihistamine where it no longer works. A new one then has to be given.
The average length of time that a person can take a particular
antihistamine before they have to move on to a new one is between 3 and 6
