Midodrine Info

What is Midodrine?

Midodrine belongs to a class of medicines that raise blood pressure by narrowing tiny blood vessels. It is taken to help people who experience a persistent drop in blood pressure when standing up. The active ingredient appears in several products, including Gutron and the brand-named Gutron tablets.

Medications with Midodrine

In Hong Kong, the most common preparations that contain midodrine are:

• Gutron - available as oral tablets in strengths of 5 mg and 10 mg.
• Midodrine - a generic tablet marketed by multiple local distributors, also in 5 mg and 10 mg strengths.
• Brand Gutron - a branded version of the same formulation, sold under the Gutron name.

These products are sold as solid tablets that are swallowed with water. All are prescription-only medicines regulated by the Hong Kong Department of Health and the Pharmacy and Poisons Board.

What Does Midodrine Treat?

Midodrine is prescribed for conditions where low blood pressure causes symptoms. The main uses include:

• Orthostatic hypotension - a drop in blood pressure when a person stands, leading to dizziness or fainting.
• Neurogenic hypotension - low blood pressure caused by nervous-system disorders such as Parkinson’s disease.
• Post-dialysis hypotension - a temporary fall in pressure after haemodialysis treatment.
• Sheehan’s syndrome-related hypotension - low pressure that can follow severe postpartum bleeding.

By tightening small blood vessels, midodrine helps maintain a steadier pressure level, reducing dizziness and the risk of fainting. The medication is generally used in adults who experience these symptoms, although a doctor may decide its suitability on an individual basis.

How Midodrine Works

Midodrine is turned into an active form in the body that makes blood vessels contract slightly. This contraction raises the pressure inside the vessels, helping blood flow back to the heart and brain when a person stands up. The effect usually begins within 30 minutes and can last a few hours, which is why the medication is often taken several times a day.

Safety Information

Common Side Effects

• Mild headache or feeling of fullness in the scalp.
• Brief episodes of pin-prick tingling in the hands or feet.
• Minor stomach discomfort or nausea.

These symptoms are usually temporary and tend to lessen as the body adjusts to the medicine.

Serious Reactions

• Sudden, severe skin rash or swelling of the face, lips, or tongue.
• Difficulty breathing or a tight feeling in the chest.

If any of these signs appear, seek immediate medical help.

Who Should Be Cautious

• People with known allergy to midodrine or any of its ingredients.
• Individuals with severe heart disease, such as uncontrolled angina, should discuss use with their doctor.
• Pregnant or breastfeeding women need professional guidance before starting treatment.

Interaction Awareness

Midodrine may interact with:

• Other blood-pressure medicines that lower pressure, such as certain antihypertensives.
• Diuretics that increase urine output, which can affect fluid balance.
• Alcohol, which can exaggerate dizziness when standing.

Because each product may have additional ingredients, refer to the specific medication’s information sheet for a complete interaction list.

What to Know Before Using

Store tablets at room temperature, protected from moisture and direct sunlight. Keep them out of reach of children. Treatment duration varies; some people use midodrine for a short period to manage symptoms, while others may need longer-term therapy. Always follow the instructions that come with your chosen product, as the exact dosing schedule can differ between Gutron, generic midodrine, and Brand Gutron.
