Vomigotrip 300

Indications

Hyoscine Hydrobromide (also called scopolamine hydrobromide) is used mainly to prevent travel sickness (motion sickness), such as nausea, vomiting and dizziness during journeys by car, bus, boat or air. In hospital it may also be used to reduce saliva and airway secretions before surgery or in end-of-life care, given by a doctor or nurse.

How It Works

Hyoscine blocks the action of acetylcholine, a chemical messenger in the nervous system. In the balance centre of the inner ear and the vomiting centre of the brain, this reduces the mixed signals that cause motion sickness. It also reduces secretions such as saliva and relaxes some smooth muscle.

Dosage and Administration

Chewable or ordinary tablets for travel sickness, adults and children over 10 years: usually 300 micrograms taken about 30 minutes before the journey, which may be repeated every 6 hours if needed, to a maximum of 3 doses in 24 hours. Children 4 to 10 years usually take 75 to 150 micrograms per dose, as directed on the label. Not for children under 4 years unless a doctor advises. Chew or suck chewable tablets, or swallow as directed. Injections are given by a doctor or nurse.

Interactions

Other medicines with anticholinergic effects add to side effects such as dry mouth, constipation and urinary retention; examples include tricyclic antidepressants (Amitriptyline), some antihistamines, antipsychotics, Amantadine and medicines for bladder spasm. Alcohol, sleeping pills and sedating medicines increase drowsiness. It can reduce the effect of Metoclopramide and Domperidone.

Contraindications

Do not use hyoscine if you are allergic to it, or if you have narrow-angle (closed-angle) glaucoma, severe constipation or blockage of the bowel, an enlarged prostate with difficulty passing urine, or myasthenia gravis.

Side Effects

Common side effects include dry mouth, drowsiness, blurred vision, dizziness and difficulty passing urine. Less common effects include a fast heartbeat, constipation, skin flushing, confusion, restlessness and, especially in older people or children, hallucinations or memory problems.

Get urgent medical help if you develop sudden eye pain with redness and blurred vision, inability to pass urine, severe confusion or hallucinations, a very fast or irregular heartbeat, high temperature, or signs of a serious allergic reaction.

Pregnancy and Lactation
