4 Clinical Particulars

4.1 Therapeutic Indications

Spasm of the gastrointestinal tract, biliary spasm, renal spasm, diagnostic aid in radiology.

4.2 Dose and Method of Administration

1 or 2 ampoules (20 or 40 mg) by intramuscular or slow intravenous injection. A maximum daily dose of 100 mg should not be exceeded.
Hyoscine butylbromide injection should not be taken on a continuous daily basis or for extended periods without investigating the cause of abdominal pain.
Product is for single use in one patient only. Discard any residue.

4.3 Contraindications

Hyoscine butylbromide injection are contraindicated in patients with: known hypersensitivity to hyoscine butylbromide or to any of the excipients of the product (excipients are listed, see Section 6.1 List of Excipients); mechanical stenosis in the gastrointestinal tract; achalasia; paralytic or obstructive ileus; intestinal atony; prostatic hypertrophy with urinary retention; myasthenia gravis; glaucoma; pathological tachyarrhythmias; megacolon.
Hyoscine butylbromide injection should not be given to patients with porphyria as, according to a single report, it has been said to exacerbate the disease.
By intramuscular injection, hyoscine butylbromide are contraindicated in patients being treated with anticoagulant drugs as intramuscular haematoma may occur. In these patients, intravenous routes may be used.

4.4 Special Warnings and Precautions for Use

In case severe, unexplained abdominal pain persists or worsens, or occurs together with symptoms like fever, nausea, vomiting, changes in bowel movements, abdominal tenderness, decreased blood pressure, fainting or blood in stool, medical advice should immediately be sought.
Hyoscine may cause drowsiness: patients so affected should not drive or operate machinery. Patients should abstain from alcohol. However, as a quaternary ammonium compound with low lipid solubility, hyoscine butylbromide cannot cross the blood/brain barrier easily and only rarely causes the central nervous system side effects associated with atropine and hyoscine.
After parenteral administration of hyoscine butylbromide, patients with visual accommodation disturbances should not drive or operate machinery until vision has normalised.
Elevation of intraocular pressure may be produced by the administration of anticholinergic agents such as hyoscine butylbromide in patients with undiagnosed and therefore untreated narrow-angle glaucoma. Patients should be advised to seek urgent ophthalmological advice if they develop a painful, red eye with loss of vision after an injection of hyoscine butylbromide.
Because of the potential risk of anticholinergic complications, caution should be used in patients prone to narrow angle glaucoma as well as in patients susceptible to intestinal or urinary outlet obstructions and in those inclined to tachyarrhythmia.
After parenteral administration, cases of anaphylaxis including episodes of shock have been observed. As with all drugs causing such reactions, patients receiving hyoscine butylbromide by injection should be kept under observation.
Patients with cardiac conditions who are undergoing parenteral treatment with hyoscine butylbromide injection should be monitored.
Hyoscine butylbromide injection can cause tachycardia, hypotension and anaphylaxis, therefore use with caution in patients with cardiac conditions such as cardiac failure, coronary heart disease, cardiac arrhythmia or hypertension, and in cardiac surgery. Monitoring of these patients is advised. Emergency equipment and personnel trained in its use must be readily available.

Use in the elderly.

Paediatric use.

Effects on laboratory tests.

4.5 Interactions with Other Medicines and Other Forms of Interactions

The anticholinergic effects of drugs such as amantadine, tri- and tetracyclic antidepressants, quinidine, antihistamines, antipsychotics, disopyramide, phenothiazines, belladonna alkaloids, other anticholinergics (e.g. tiotropium, ipratropium, atropine-like compounds) and MAO inhibitors etc, together with the tachycardia induced by beta-sympathomimetics, can be potentiated by hyoscine butylbromide.
The concomitant administration of dopamine antagonists, such as metoclopramide, can reciprocally antagonise the effect on gastrointestinal tract motility.

4.6 Fertility, Pregnancy and Lactation

Effects on fertility.

4.7 Effects on Ability to Drive and Use Machines

No studies on the effects on the ability to drive and use machines have been performed. However, patients should be advised that they may experience undesirable effects such as accommodation disorder or dizziness during treatment with hyoscine butylbromide injection.
Therefore, caution should be recommended when driving a car or operating machinery. If patients experience accommodation disorder or dizziness, they should avoid potentially hazardous tasks such as driving or operating machinery.

4.8 Adverse Effects (Undesirable Effects)

Many of the listed adverse effects of hyoscine butylbromide injection can be attributed to its anticholinergic properties. Anticholinergic side effects of hyoscine butylbromide injection are generally mild and self-limited.
