Hydrochlorothiazide + S-Amlodipine
Uses of Hydrochlorothiazide + S-Amlodipine
Hydrochlorothiazide + S-Amlodipine is used to manage high blood pressure (hypertension). It combines a diuretic with a calcium channel blocker for more effective blood pressure control.
This combination is commonly used for:
• Hypertension: Lowers high blood pressure and helps reduce the risk of complications such as heart attack and stroke.
• Long-term blood pressure management: Used as part of ongoing treatment to maintain blood pressure within a healthy range.
• Fluid retention associated with high blood pressure: Helps reduce excess fluid build-up that can contribute to raised blood pressure.

How Hydrochlorothiazide + S-Amlodipine works
Hydrochlorothiazide + S-Amlodipine works through two complementary mechanisms to lower blood pressure.
Hydrochlorothiazide is a thiazide diuretic. It prompts the kidneys to remove excess salt and water from the body, reducing fluid volume in the blood vessels and lowering blood pressure.
S-Amlodipine is a calcium channel blocker. It prevents calcium from entering the muscle cells of blood vessels, causing them to relax and widen. This makes it easier for the heart to pump blood.
Together, these two medicines provide more effective, longer-lasting blood pressure control than either used alone.

Age and Dose Restrictions
This medicine is intended for adult use only and is not recommended for children or adolescents under 18 years of age.
Contraindications
Hydrochlorothiazide + S-Amlodipine is contraindicated in patients with known hypersensitivity to either of the active ingredients. It is also contraindicated in patients who are unable to produce urine (anuria) and those with abnormally low blood pressure (hypotension).
Other Medications to Avoid
Hydrochlorothiazide + S-Amlodipine may interact with non-steroidal anti-inflammatory drugs (e.g., ibuprofen and naproxen), anti-fungal medications (e.g., itraconazole, ketoconazole and ritonavir), and anti-microbial medicines (such as rifampicin, phenytoin and phenobarbital).
It may also interact with certain cholesterol-lowering medicines (e.g., simvastatin), which could increase the risk of muscle damage.
Overdose and Missed Dose
Taking more than the prescribed dose may cause excessive widening of blood vessels, resulting in very low blood pressure and a slow heartbeat. If you suspect an overdose, seek emergency medical attention immediately.
If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not take a double dose to make up for the missed one.

Drinking plenty of water may help manage dizziness and flushing.
Rest and proper hydration can also alleviate symptoms like headache and fatigue.

Caution in Other Conditions
