Hyoscine Hydro Bromide Precaution - What You Need to Know
Before using Hyoscine Hydro Bromide, patients must consult their healthcare provider, as there are several precautions to consider:
- Allergic Reactions: If a patient has a known hypersensitivity to Hyoscine Hydro Bromide or any components of the medication, it should be avoided. Allergic reactions may include symptoms like rash, itching, or swelling, particularly of the face, tongue, or throat.
- Glaucoma: Hyoscine Hydro Bromide should be used with caution in patients with narrow-angle glaucoma or a history of eye conditions that increase intraocular pressure, as the medication may worsen these conditions by causing pupil dilation.
- Prostatic Hypertrophy and Urinary Retention: This medication can exacerbate symptoms in patients with benign prostatic hyperplasia (BPH) or those experiencing difficulty urinating, as it can reduce bladder tone and lead to urinary retention.
- Gastrointestinal Motility Disorders: In patients with conditions such as ileus (intestinal obstruction) or other gastrointestinal motility issues, Hyoscine Hydro Bromide should be used cautiously, as it may further impair motility.
- Cardiovascular Conditions: Caution is required when administering Hyoscine Hydro Bromide in patients with heart conditions such as tachycardia or arrhythmias, as the drug has anticholinergic effects that can increase heart rate.
- Elderly Patients: Older adults may be more sensitive to the side effects of this medication, particularly confusion, dizziness, and sedation. It is important for healthcare providers to assess the potential risks and adjust the dosage as necessary.
- Pregnancy and Lactation: Hyoscine Hydro Bromide is classified as Category C for pregnancy, indicating that its use during pregnancy should be avoided unless absolutely necessary. It is also excreted in breast milk, so breastfeeding mothers should consult a doctor before using this medication.
Hyoscine Hydro Bromide Indication - Uses and Benefits
Hyoscine Hydro Bromide is primarily used for the treatment of a variety of conditions related to the gastrointestinal and nervous systems:
- Motion Sickness: One of the most common uses for Hyoscine Hydro Bromide is to prevent and treat symptoms of motion sickness, including nausea, vomiting, and dizziness, especially in cases of travel sickness (e.g., sea sickness, car sickness, or air sickness).
- Postoperative Nausea and Vomiting: It is often used to prevent nausea and vomiting that can occur after surgery, particularly when caused by the effects of anesthesia or surgical manipulation.
- Gastrointestinal Spasms: The drug can be used to treat spasms in the gastrointestinal tract, such as those caused by irritable bowel syndrome (IBS), or for relief from abdominal cramps or discomfort.
- Pre-anesthetic Medication: Hyoscine is used as a pre-anesthetic agent to reduce salivation and secretions in the airways during surgery.
- Parkinson’s Disease and Extrapyramidal Symptoms: Hyoscine can be used to treat extrapyramidal symptoms such as rigidity, tremors, and abnormal movements caused by antipsychotic medications, particularly in the context of Parkinson’s disease.
Hyoscine Hydro Bromide Contraindications - Important Warnings
Hyoscine Hydro Bromide should not be used in the following conditions:
- Hypersensitivity: Any patient with a known hypersensitivity to Hyoscine Hydro Bromide or similar drugs, such as other anticholinergics, should avoid using this medication.
- Glaucoma: In patients with narrow-angle glaucoma, where the increased intraocular pressure can lead to damage to the optic nerve, Hyoscine Hydro Bromide should be avoided, as it can worsen the condition by dilating the pupils and increasing pressure.
- Severe Cardiovascular Disease: Patients with severe heart conditions such as tachycardia or arrhythmias should not use Hyoscine Hydro Bromide, as its anticholinergic effects can exacerbate these issues.
- Myasthenia Gravis: This condition, characterized by weakness and rapid fatigue of the voluntary muscles, may be worsened by Hyoscine Hydro Bromide due to its interference with neuromuscular transmission.
- Urinary Retention: Patients with a history of urinary retention, especially those with prostate enlargement or similar conditions, should avoid this medication, as it can worsen urinary retention.
Hyoscine Hydro Bromide Side Effects - What to Expect
Common and serious side effects associated with Hyoscine Hydro Bromide include:
- Common Side Effects:
- Dry mouth
- Blurred vision
- Drowsiness or sedation
- Dizziness
- Constipation
- Urinary retention
- Serious Side Effects:
- Tachycardia: Hyoscine may cause an increase in heart rate (tachycardia), which can be dangerous for individuals with heart conditions.
- Confusion and Hallucinations: Older adults may experience confusion, agitation, or hallucinations due to the anticholinergic effects of Hyoscine, which can lead to memory problems.
- Severe Allergic Reactions: Hypersensitivity reactions, such as anaphylaxis, can occur, though these are rare.
- Urinary Retention: Patients may experience difficulty urinating, which can be dangerous, especially in those with pre-existing urinary tract or prostate issues.
- Glaucoma Crisis: Hyoscine may precipitate a glaucoma crisis in patients with closed-angle glaucoma, leading to sudden increased eye pressure and potential vision damage.
Patients should monitor for these side effects and immediately inform their healthcare provider if they experience any severe symptoms.

Hyoscine Hydro Bromide Mode of Action - How It Works
Hyoscine Hydro Bromide is an anticholinergic (antimuscarinic) drug that works by blocking the action of acetylcholine on muscarinic receptors in the body. Acetylcholine is a neurotransmitter involved in several bodily functions, including the regulation of smooth muscle contraction, secretion of fluids, and nerve transmission.
- In the gastrointestinal tract, Hyoscine blocks muscarinic receptors, reducing the motility of smooth muscle and preventing spasms. This action helps relieve symptoms such as nausea, vomiting, and abdominal cramps.
- In the nervous system, it reduces the effects of parasympathetic nerve activity, leading to reduced secretions in the respiratory tract (helpful in surgery) and improved symptoms in Parkinson's disease or other conditions causing extrapyramidal side effects.
- In motion sickness, Hyoscine inhibits the signals to the brain that trigger nausea and vomiting, thus preventing the symptoms of motion sickness during travel or other situations that might induce such symptoms.
Hyoscine Hydro Bromide Drug Interactions - What to Avoid
Hyoscine Hydro Bromide may interact with a variety of other drugs, affecting either its efficacy or the safety of other treatments:
- Other Anticholinergic Drugs: The combined use of other anticholinergic medications, such as atropine or certain antihistamines, can lead to excessive anticholinergic effects, including dry mouth, blurred vision, constipation, confusion, or urinary retention.
- Antihypertensive Medications: Some antihypertensive drugs, especially those that work through mechanisms that lower heart rate, may interact with Hyoscine Hydro Bromide and increase the risk of tachycardia or arrhythmias.
- Tricyclic Antidepressants (TCAs): Hyoscine Hydro Bromide and TCAs both have anticholinergic properties, and their concurrent use can intensify side effects such as dry mouth, constipation, urinary retention, and cognitive disturbances.
- CNS Depressants: The sedative effects of CNS depressants (such as benzodiazepines, barbiturates, or alcohol) may be enhanced when used with Hyoscine Hydro Bromide, increasing the risk of drowsiness, confusion, or sedation.
- Digoxin: Hyoscine Hydro Bromide may increase the risk of digoxin toxicity by altering heart rate and rhythm. Patients taking digoxin should be closely monitored for signs of digoxin toxicity.
Hyoscine Hydro Bromide Adult Dose - Recommended Dosage
The adult dosage of Hyoscine Hydro Bromide depends on the condition being treated:
- Motion Sickness: A typical dose is 1–2 mg taken orally 30 minutes before travel. This can be repeated every 4–6 hours as necessary, but not exceeding 3 doses in 24 hours.
- Postoperative Nausea and Vomiting: Typically, 0.3–0.6 mg is administered intravenously or intramuscularly before surgery, or as directed by a healthcare provider.
- Gastrointestinal Spasms: A dose of 0.3–0.6 mg may be given orally or by injection, repeated every 4 hours as needed.
- Pre-anesthetic: 0.3–0.6 mg is often administered intramuscularly 30–60 minutes before surgery to reduce secretions.
Hyoscine Hydro Bromide Child Dose - Dosage for Children
Hyoscine Hydro Bromide is generally not recommended for children under the age of 2 due to the potential for severe side effects, including respiratory depression and altered heart rate. For older children, doses should be carefully adjusted according to their weight and the specific condition being treated.
- Motion Sickness: In children aged 2 to 6 years, 0.25–0.5 mg can be administered orally every 6–8 hours, with a maximum of 2 doses per day.
- Postoperative Nausea and Vomiting: Pediatric doses are usually around 0.3–0.6 mg intramuscularly or intravenously, depending on the child’s age and weight.
Consultation with a pediatrician is recommended before using this medication in children.
Hyoscine Hydro Bromide Renal Dose - Dosage for Kidney Conditions
In patients with renal impairment, Hyoscine Hydro Bromide should be used with caution, as renal dysfunction may alter the drug’s clearance and increase the risk of side effects. Dose reductions are typically not required unless the renal impairment is severe. Close monitoring is essential for such patients.
