dizziness and to prevent and treat motion sickness.
This medication should not be used in the following cases:
This medication is intended for the treatment of
dizziness and not for disturbances of balance: talk to your doctor or pharmacist.
This antihistamine has
atropinic effects. It can cause acute
glaucoma in susceptible persons: red, hard and painful eyes, with blurred vision. An emergency consultation with an ophthalmologist is necessary.
Precautions are necessary in cases of
epilepsy , pyloric
stenosis , dementia,
myasthenia gravis and the elderly.
Avoid alcoholic drinks during treatment: increased risk of drowsiness.
Conductor: This medication may be responsible for decreased vigilance, especially at the beginning of treatment.
Tell your doctor or pharmacist if you are taking any other medicines that have
atropine or
sedative effects (tranquillizers, sleeping pills, some cough or pain medications containing
opioids ,
antidepressants ,
neuroleptics, etc.).
Pregnancy : The use of this medication is possible during pregnancy, provided that you respect the prescription of your doctor. Use in the days prior to delivery should be reported to the physician; special monitoring of the newborn may be necessary.

- avoid coffee, alcoholic or soft drinks;
- privilege certain places (at the front by coach, at the wings by plane, at the center of the bridge on a boat).

accommodation
"Focus" of the eye, allowing clear vision close up. Presbyopia is the most common disorder of accommodation; some drugs such as atropine may cause passenger accommodation problems.
adenoma of the prostate
Increase in the volume of the prostate gland located under the bladder of the man. This increase in volume is benign, has no relationship to cancer, but can interfere with the passage of urine into the urethra through the gland.
Symptoms that suggest the presence of a prostate adenoma are:
- difficulty urinating (slowness, weakness of the spray);
- the need to get up several times at night to urinate;
- urges to urinate imperiously and difficult to control.
Certain drugs, especially atropinic drugs, may have the undesirable effect of aggravating the discomfort and may lead to a total blockage of the evacuation of the bladder. They are therefore contraindicated or should be used cautiously in men with the symptoms described above.
antidepressants
Medication that works against depression. Some antidepressants are also used to combat obsessive-compulsive disorder, generalized anxiety, certain rebellious pain, enuresis, etc.
Depending on their mode of action and adverse effects, antidepressants are divided into different families: imipraminic antidepressants, serotonin reuptake inhibitors, selective or non-selective MAOIs. Finally, other antidepressants do not belong to any of these families, because they possess original properties.
The mode of action of antidepressants has two main aspects: the relief of moral suffering and the fight against inhibition which removes all will to action from the depressed. There may be a time lag between these two effects: moral suffering may persist, while the capacity for action reappears. During this short period, the risk of suicide in some depressed people can be increased. The physician takes it into account in its prescription (possible association with a tranquillizer) and it must imperatively be respected.
antihistamines
Medication that opposes different effects of histamine. Two main types exist: antihistamines type H1 (antiallergic) and antihistamines type H2 (gastric antiulcer). Some antihistamines of type H1 are sedative, others do not alter vigilance.
atropine
Medication with effects similar to those of atropine. Atropinics fight spasms and diarrhea. Adverse effects of atropinic drugs include: thickening of bronchial secretions, dry mouth and mucous membranes, constipation, risk of urine blockage and acute glaucoma in susceptible persons, accommodation disorders, abnormal sensitivity to light by dilation of the pupil. Taking several atropine medicines increases the risk of adverse effects. In the event of overdose or accidental ingestion, the following signs may also appear: red and warm skin, fever, acceleration of breathing, fall or, on the contrary, elevated blood pressure, agitation, hallucinations, poor coordination of movements. Emergency care should be given to your doctor or, if not available, call 15, 112 or an emergency medical service.
In addition to atropine and its derivatives, other drugs have atropine effects: imipraminic antidepressants, some antihistamines, antispasmodics, antiparkinsonian and neuroleptic.
épilpesie
A chronic seizure disorder associated with abnormal electrical activity of a group of brain cells. Its manifestations, varying in intensity, range from the sudden drop in attention (absences, or small evil) to loss of consciousness accompanied by abnormal muscle movements (convulsions, or great evil). Partial epilepsy, as its name implies, does not concern the whole body: the jerky movements only touch one or more muscle groups.
glaucoma
Disease characterized by increased pressure of the fluids contained in the eye (intraocular hypertension).
This general term covers two totally different affections:
- Open angle glaucoma or chronic glaucoma is the most frequent; it is generally symptom-free, detected by the measurement of intraocular tension in the ophthalmologist. It does not cause acute seizures, and treatment relies primarily on beta-blocking eye drops. People with open-angle glaucoma should not use cortisone derivatives without prior ophthalmologic advice.
- Closed-angle glaucoma or acute glaucoma is more rare. Between seizures, intraocular tension is normal. But the inadvertent use of atropine medicines (especially eye drops) causes an acute crisis of intraocular hypertension which can permanently damage the retina in a few hours. It is an ophthalmological emergency that is recognized by a brutally red eye, horribly painful, hard as a glass ball, and whose vision becomes blurred.
The angle in question in these two affections is the irido-corneal angle. It is indeed between the iris and the cornea that is located the system of evacuation of the liquids of the eye. A slightly open (closed) angle exposes a total obstruction of the evacuation system. This obstruction can occur when the iris is opened to the maximum (mydriasis) under the effect of an atropinic drug: the iris then comes to be attached to the cornea.
Contraindications for atropine medicines are limited to those who have already had closed-angle glaucoma or who have been detected by an ophthalmologist. Those who suffer from chronic open-angle glaucoma are not affected by these contraindications.
Hepatic insufficiency
Inability of the liver to perform its function, which is essentially the elimination of some waste, but also the synthesis of many biological substances essential to the body: albumin, cholesterol and coagulation factors (vitamin K, etc.).
gravis
Disease of the muscles resulting in abnormal fatigability during exercise. There are more or less severe myasthenia gravis.
neuroleptics
Family of medicines used in the treatment of certain nervous disorders or various symptoms: digestive disorders, menopausal disorders, etc.
opiates
A chemical family that includes opium and its derivatives. In addition to drugs such as opium or heroin, the opiate family includes morphine (strong analgesic), codeine (antitussive and analgesic) and many other substances.
sedatives
- Quiets, calms down.
- Medication belonging to different families: anxiolytics, hypnotics, analgesics, cough suppressants, antiepileptics, neuroleptics, etc. but also antidepressants, antihistamines H1, antihypertensives. A sedative can be responsible for drowsiness and increase the effects of alcohol.
stenosis
Shrinkage, for example of an artery.
symptomatic treatment
Treatment that suppresses or alleviates the symptoms of a disease without addressing its cause.
dizziness
Symptom that can mean an impression of loss of balance (common sense) or, more strictly, a sense of rotation on oneself or the environment (medical sense).
