1. What Oybutynin hydrochloride tablets are and
what they are used for
Oxybutynin hydrochloride tablets belong to the group of
spasm-relieving agents (a so-called spasmolytic).
Oxybutynin hydrochloride tablets act by reducing the
muscle spasms of the bladder. It is these spasms that
cause the feeling of having to urinate frequently, which
in turn can lead to involuntary loss of urine. Oxybutynin
relaxes the bladder muscle, so that the bladder can hold
more urine and the frequent urge to urinate is reduced.
Oxybutynin hydrochloride tablets may be prescribed by
the doctor for the treatment of the involuntary loss of
urine as a result of an unstable or over-active bladder. In
other words, when it is not possible to keep the urge to
urinate and the frequent need to urinate normally under

obstruction of the urinary tract or as a result of
enlargement of the prostate (prostatic hypertrophy).

(autonomous neuropathy, Parkinson's disease),
reduced liver or kidney function, a rupture of the
diaphragm with regurgitating gastric acid (hiatus
hernia with reflux oesophagitis) or other severe
gastrointestinal disorders
! if you have the symptoms of an overactive thyroid
gland (hyperthyroidism), cardiovascular diseases,
heart failure, disturbances of heart rhythm, raised
blood pressure (hypertension) and enlarged
prostate (prostatic hypertrophy). These symptoms
may be intensified by the use of oxybutynin.
! if you have heart disease or high blood pressure
! if you have an irregular heart beat (palpitations)
and/or increased or rapid heart beat
! if you have an enlarged prostate gland
! if you have indigestion or heart burn caused by a “

which are used to treat bone diseases
! in the case of treatment of patients subject to a high
environmental temperature or in cases of fever.
There is the risk of a greatly increased body
temperature (hyperpyrexia) due to a decrease in
sweat production as a result of the use of
! because oxybutynin can cause a dry mouth. In
cases of long-term use this can lead to an increased
risk of the development of dental cavities (caries) or
to abnormalities of the tooth pockets, oral candida
(a fungal infection) in the oral cavity or general


discomfort caused by the reduced salivation.
Regular dental check-ups are therefore advisable
during longterm treatment. The ability of sublingual
tablets to melt under the tongue may deteriorate
due to dry mouth. You should moisten the mouth
with the tongue or with a little water before taking
sublingual tablets. Careful oral hygiene is necessary
