Other medicines and Hyoscine for Injection
Taking another medicine while you are being given Hyoscine for Injection can increase its side effects. Tell your doctor if you are taking, have recently taken or might take any other medicine.
Examples of medicines that can increase the side effects of Hyoscine for Injection are:
• disopyramide, quinidine, medicines used to treat an irregular heart beat
•tiotropium, ipratropium, (atropine-like compounds); used to treat respiratory conditions such as COPD (Chronic Obstructive Pulmonary Disease) and asthma •tricyclic, and tetracyclic antidepressants plus monoamine oxidase inhibitors (MAOI); used to treat depression •antihistamines; used to treat hay fever and other allergies •metoclopramide and domperidone; used to relieve the symptoms of nausea and vomiting •phenothiazines, butyrophenones, clozapine; used to control nausea (feeling sick) and vomiting (being sick) and to treat mental illness
•amantadine; used for Parkinson’s disease and influenza.
Hyoscine for Injection may also reduce the effects of the following medicines:
• levodopa used to treat Parkinson’s disease
• Nitrate (GTN) tablets used under the tongue for angina
• parasympathomimetics: used to treat conditions such as glaucoma, depression, asthma, heart conditions and retention of urine.
Hyoscine for Injection may increase your heart rate if you take a drug such as salbutamol (or another beta agonist) for asthma.
Hyoscine for Injection with food, drink and alcohol
You should not drink alcohol while you are being given Hyoscine for Injection as it may cause drowsiness.
Pregnancy and Breastfeeding
Use of hyoscine during pregnancy may cause breathing problems in the newborn infant. Use during pregnancy and breast feeding is not recommended. If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before taking this medicine.

Use in Children
The dose in children is usually 15 micrograms per kg body-weight (Use with caution in children as children are more susceptible to side effects). 103046/5
...........................>4
In case severe unexplained abdominal pain persists or worsens or occurs together with symptoms like fever, nausea, vomiting, changes in bowl movements, abdominal tenderness, decreased blood pressure, fainting or blood in stool, appropriate diagnostic measures are needed to investigate the aetiology of the symptoms.
Heat prostration can occur at high ambient temperatures, due to decreased sweating. Hyoscine should be administered with caution to patients with pyrexia.
Elevation of intraocular pressure may be produced by the administration of anticholinergic agents such as hyoscine in patients with undiagnosed and therefore untreated angle-closure glaucoma. Urgent ophthalmological advice should be sought in case patients should develop a painful, red eye with loss of vision after the injection of hyoscine.
After parenteral administration of hyoscine, cases of anaphylaxis including episodes of shock have been observed. As with all drugs causing such reactions, patients receiving hyoscine by injection should be kept under observation.
Children: Use with caution in children as they may be more susceptible to adverse effects.
4.5 Interactions with other medicinal products and other forms of interaction
Anticholinergics/antimuscarinics: Many drugs have anticholinergic effects; concomitant use of two or more such drugs can increase side-effects such as dry mouth, urine retention and constipation; concomitant use can also lead to confusion in the elderly.
Anticholinergic (antimuscarinic) side-effects may be intensified by concomitant use of hyoscine with drugs such as tricyclic and tetracyclic antidepressants, monoamine oxidase inhibitors (MAOIs), antihistamines, quinidine, amantadine, antipsychotics (e.g. phenothiazines, butyrophenones, clozapine), disopyramide and other anticholinergics (e.g. tiotropium, ipratropium, atropine-like compounds) may be intensified by hyoscine..
Nitrates: Reduced effect of sub-lingual nitrates (failure to dissolve under the tongue due to dry mouth).
Beta-adrenergic agents: The tachycardic effects of beta-adrenergic agents may be enhanced by hyoscine.
Metoclopramide and Domperidone - Dopamine antagonist: Although hyoscine is not indicated for gastrointestinal treatment, concomitant treatment with dopamine antagonists such as metoclopramide or domperidone may result in diminution of the effects of both drugs on the gastrointestinal tract.
Dopaminergics: Hyoscine may reduce absorption of levodopa
Alcohol: Patients should be advised to avoid alcohol prior to having any procedure which requires administration of hyoscine as an increased sedative effect has been reported when hyoscine is given with alcohol.
Parasympathomimetics: Hyoscine antagonises the effects of parasympathomimetics
4.6 Fertility, pregnancy and lactation
Pregnancy: There are limited data from the use of hyoscine in pregnant women. Animal studies are insufficient with respect to reproductive toxicity. Hyoscine crosses the placenta. Use of hyoscine during pregnancy may cause respiratory depression in the neonate. As a precautionary measure hyoscine is not recommended during pregnancy.
Breast-feeding: There is insufficient information on the excretion of hyoscine and its metabolites in human milk.
Elderly
Hyoscine is not recommended for use in older people
Your doctor will decide the dose that is best for you. If you do not understand, or are in any doubt, ask your doctor or nurse.
If you use more Hyoscine for Injection than you should
If you think you have received more Hyoscine for Injection than you should, please tell your doctor or nurse immediately. Signs of an overdose include dilated pupils, a rapid heart beat, rapid breathing, abnormally high temperature, restlessness, excitement, confusion and hallucinations (seeing or hearing things that aren’t there).
If you have missed a dose of Hyoscine for Injection
If you think you have missed a dose of Hyoscine for Injection, please tell your doctor or nurse.

Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme www.mhra.gov.uk/yellowcard.
4.9 Overdose
Symptoms:
Serious signs of poisoning following acute overdosage have not been observed in man. In the case of overdosage, anticholinergic symptoms such as urinary retention, dry mouth, reddening of the skin, tachycardia, inhibition of gastrointestinal motility and transient visual disturbances may occur. Cheynes-Stokes respiration has been reported. Other symptoms may include dilated pupils, hyperthermia, hyperpyrexia, hypertension, nausea and vomiting.
Toxic doses may also cause CNS stimulation marked by restlessness, confusion, excitement, ataxia, incoordination, paranoid and psychotic reactions, hallucinations, delirium, and occasionally seizures. In severe overdosage, central stimulation may give way to CNS depression, coma circulatory and respiratory failure and death.
Treatment:
In the unlikely event of overdosage, supportive therapy should be implemented. Physostigmineby slow intravenous injection in a dose of 1 to 4mg has been used to reverse the
breathing, muscle stiffness, agitation and reduced consciousness. The level of an enzyme called creatine phosphokinase may be raised in your blood which suggests damage to muscles.
Reporting of side effects
If you get any side effects, talk to your doctor, pharmacist or nurse.
This includes any possible side effects not listed in this leaflet.
You can also report side effects directly via the Yellow Card Scheme
Website: http://www.mhra.gov.uk/ yellowcard. By reporting side effects you can help provide more information on the safety of this medicine.

anticholinergic effects, however, such use is hazardous and is not generally recommended. Diazepam may be given to control excitement. For patients with glaucoma, pilocarpine should be given locally. Cardiovascular complications should be treated according to usual therapeutic principles.
In cases of respiratory paralysis, intubation and artificial respiration should be undertaken. Catheterisation may be required for urinary retention.
5. PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Hyoscine is an anticholinergic drug which inhibits the muscarinic actions of acetylcholine at post-ganglionic parasympathetic neuroeffector sites including smooth muscle, secretory glands and CNS sites. Small doses effectively inhibit salivary and bronchial secretions and sweating and provide a degree of amnesia. Hyoscine is a more powerful suppressor of salivation than atropine and usually slows rather than increases heart rate.
5.2 Pharmacokinetic properties
Hyoscine is rapidly absorbed following IV or IM injection and is reversibly bound to plasma protein. Hyoscine is reported to cross the placenta and blood brain barrier. Hyoscine is almost completely metabolised by the liver and excreted in the urine. In one study in man, 3.4% of a single dose, administered by subcutaneous injection was excreted unchanged in urine within 72 hours.
