HYTIDE 12.5

# HYDROCHLOROTHIAZIDE 12.5 MG ## SHORT DESCRIPTION **Hydrochlorothiazide 12.5 mg** is a **thiazide diuretic (“water pill”)** used primarily to help lower high blood pressure and reduce excess fluid retention (edema). It works mainly by helping the kidneys remove excess **sodium and water** from the body. Hydrochlorothiazide may be used alone or together with other medicines, such as ACE inhibitors, ARBs, or other blood-pressure medicines. --- ## KEY BENEFITS * Helps **lower high blood pressure**. * Helps reduce excess **fluid and swelling (edema)**. * Promotes removal of excess sodium and water through urine. * May be used alone or as part of combination blood-pressure treatment. * Can help reduce fluid accumulation associated with certain medical conditions. --- ## USES / INDICATIONS Hydrochlorothiazide 12.5 mg may be prescribed for: 1. **Hypertension (high blood pressure)** 2. **Edema associated with heart failure** 3. Fluid retention associated with certain **kidney disorders** 4. Fluid retention associated with certain **liver disorders** 5. Other conditions involving excess fluid, when specifically recommended by a healthcare professional It may also be included in combination medicines for blood-pressure control. --- ## HOW IT WORKS Hydrochlorothiazide acts on the **distal convoluted tubule of the kidney**. It inhibits the sodium-chloride (**Na⁺/Cl⁻**) cotransporter, reducing the reabsorption of sodium and chloride. This causes the kidneys to excrete more: * Sodium * Chloride * Water The resulting reduction in fluid volume helps lower **blood pressure** and reduce **edema**. With long-term use, blood pressure remains lower partly because of reduced peripheral vascular resistance. --- ## DOSAGE & ADMINISTRATION ### Typical Adult Dose for Hypertension A commonly used starting dose is **12.5 mg once daily**. Your healthcare professional may adjust the dose depending on your blood-pressure response and other medicines you take. ### For Edema Dosing for edema can vary considerably depending on the underlying condition and severity. Higher or divided doses may sometimes be prescribed under medical supervision. ### How to Take * Take exactly as prescribed. * It is usually taken **once daily**, preferably in the morning. * Taking it later in the day may cause increased urination during the night. * Take with or without food unless your healthcare professional advises otherwise. * Maintain adequate fluid intake according to your medical condition and doctor's advice. ### Missed Dose Take the missed dose when remembered unless it is close to the next scheduled dose. **Do not double the dose.** --- ## SIDE EFFECTS ### Common Side Effects Possible side effects include: * Increased urination * Dizziness * Lightheadedness * Headache * Weakness * Increased thirst * Low blood pressure Hydrochlorothiazide can alter electrolyte levels. ### Electrolyte-Related Effects It may cause: * **Low potassium** * Low sodium * Low magnesium * Increased calcium levels Symptoms of significant electrolyte imbalance may include: * Muscle cramps * Muscle weakness * Confusion * Irregular heartbeat * Severe fatigue ### Other Possible Effects * Increased blood sugar * Increased uric acid * Increased sensitivity to sunlight * Skin rash * Nausea ### Serious Side Effects Seek medical attention for: * Severe dizziness or fainting * Severe weakness * Confusion * Significant heart rhythm changes * Severe allergic reaction * Severe skin reaction * Signs of serious electrolyte imbalance --- ## PRECAUTIONS & WARNINGS ### Low Blood Pressure Hydrochlorothiazide can lower blood pressure too much in some people, particularly when treatment begins or when combined with other blood-pressure medicines. Rise slowly from sitting or lying positions if you experience dizziness. ### Electrolyte Imbalance Regular monitoring may be required for people at risk of: * Low potassium * Low sodium * Low magnesium * High calcium ### Kidney Disease Hydrochlorothiazide may be less effective in severe kidney impairment and may not be appropriate in certain patients. Tell your healthcare professional if you have kidney disease. ### Liver Disease Electrolyte disturbances and dehydration can be particularly problematic in people with significant liver disease. ### Diabetes Hydrochlorothiazide may increase blood glucose levels in some patients. People with diabetes may require closer blood-glucose monitoring. ### Gout Hydrochlorothiazide can increase **uric acid** levels and may trigger or worsen gout in susceptible individuals. ### Photosensitivity Hydrochlorothiazide can increase sensitivity to sunlight. Use appropriate sun protection and report unusual or severe skin reactions. ### Lupus Thiazide diuretics may occasionally worsen or activate lupus-related symptoms in susceptible patients. ### Skin Cancer Risk Long-term hydrochlorothiazide exposure has been associated with an increased risk of certain **non-melanoma skin cancers**, particularly with cumulative exposure. Protect skin from excessive sunlight and report unusual or persistent skin lesions to a healthcare professional. ### Pregnancy Hydrochlorothiazide is not generally used simply to treat routine pregnancy-related swelling. Pregnant patients should use it only when specifically recommended by a healthcare professional. ### Breastfeeding Discuss hydrochlorothiazide use with your healthcare professional. Higher doses may reduce milk production. --- ## DRUG INTERACTIONS ### Other Blood-Pressure Medicines Combining hydrochlorothiazide with other antihypertensive medicines may increase the risk of **low blood pressure**. ### ACE Inhibitors and ARBs Medicines such as lisinopril, enalapril, losartan, or valsartan may enhance blood-pressure lowering. They may also affect kidney function and potassium levels, depending on the combination. ### Lithium Hydrochlorothiazide can reduce lithium elimination and significantly increase **lithium levels**, potentially causing toxicity. This combination requires careful medical supervision. ### Digoxin Electrolyte abnormalities caused by hydrochlorothiazide, particularly low potassium or magnesium, can increase the risk of **digoxin toxicity**. ### NSAIDs Medicines such as: * Ibuprofen * Naproxen * Diclofenac may reduce the diuretic and blood-pressure-lowering effects of hydrochlorothiazide and may increase kidney risk in susceptible patients. ### Corticosteroids Corticosteroids may increase the risk of **low potassium** and may worsen blood-glucose control. ### Diabetes Medicines Hydrochlorothiazide can affect blood glucose and may alter the requirements for certain diabetes medicines. ### Other Diuretics Combining diuretics can increase fluid loss and electrolyte disturbances. ### Cholestyramine / Colestipol These medicines may reduce absorption of hydrochlorothiazide if taken at the same time. Your healthcare professional may recommend separating administration. --- ## STORAGE INFORMATION * Store according to the manufacturer's instructions. * Keep at room temperature unless the product label states otherwise. * Protect from excessive heat, moisture, and direct sunlight. * Keep tablets in their original packaging. * Keep out of reach and sight of children. * Do not use after the expiry date. * Do not use tablets if the packaging is damaged. --- ## PRESCRIPTION STATUS **Prescription medicine in many countries.** Hydrochlorothiazide 12.5 mg should be used according to the advice of a qualified healthcare professional because blood pressure, kidney function, and electrolyte levels may require monitoring.
