Side effects are problems that occur when treatment goes beyond the
desired effect or problems that occur in addition to the desired
When side effects of necessary medication are severe, sometimes a
second medication, lifestyle change, dietary change, or other
measure may help to minimize them. Drug manufacturers are required
to list all known side effects of their products.
Fatigue, nausea, vomiting, decreased blood cell counts, hair loss,
and mouth sores are instances of side effects of cancer treatment
that occur in addition to the desired therapeutic effect. A
hemorrhage from the use of too much anticoagulant (such as heparin)
is a side effect caused by treatment going beyond the desired
effect. As with all drugs, some people react badly to
antidepressants, while side effects can seem quite mild in others.
The irony here of course is that, helpful as antidepressants may be
for some people at some times, these side effects can be very
depressing in themselves.
Because no one antidepressant has been proven to be any more
effective than any other, the choice of which drug to prescribe
often rests on their different side effects.
Drowsiness or dizziness, possible addiction or dependence, dry
mouth or urinary retention are some of the possible side effects of
Muscle relaxants are often prescribed in the treatment of acute low
back pain in an attempt to improve the initial limitations in range
of motion from muscle spasm and to interrupt the pain-spasm-pain
cycle. Limiting muscle spasm and improving range of motion will
prepare the patient for therapeutic exercise. Muscle relaxants work
by acting on the central nervous system. In the United States, they
are available only with a physician’s prescription. Some muscle
relaxants are available in Canada without a prescription. Most come
only in tablet form. However, methocarbamol (Robaxin) is available
in both tablet and injectable forms. Examples of muscle relaxants
are carisoprodol (Soma), chlorzoxazone (Parafon Forte DSC),
cyclobenzaprine (Flexeril), and methocarbamol (Robaxin).
Muscle relaxants are usually prescribed along with rest, exercise,
physical therapy, or other treatments. Although the drugs may
provide relief, they should never be considered a substitute for
these other forms of treatment. These drugs may make the injury
feel so much better that one is tempted to go back to normal
activity, but doing too much too soon can actually make the injury
Other common side effects or muscle relaxants are vision changes,
such as double vision or blurred vision; lightheadedness;
drowsiness; and dry mouth. These problems usually go away as the
body adjusts to the drug and do not require medical treatment.
Side-effects of muscle relaxants increase the symptom that the drug
was supposed to control. This may lead people to take ever more of
a symptom-producing drug in an effort to control that symptom.
Muscle relaxants may interact with some other medicines. When this
happens, the effects of one or both of the drugs may change or the
risk of side effects of muscle relaxants may be greater. Anyone who
plans to take muscle relaxants should let the physician know all
other medicines, including over-the-counter or nonprescription
medicines, that he or she is taking.
Every medication contains chemicals that may cause side effects.
Some side effects are physical, such as nausea or blurred vision,
and some side effects affect mood and emotions. If someone has a
mental disorder, why not check if medications cause the symptoms.
List what medications are taken, and compare the medication history
to the symptom history. Ask medical professionals about the side
effects of any drugs that they prescribe for you or your family.
