Aldactazide® combines spironolactone and hydrochlorothiazide to treat hypertension and edema. It pairs a potassium-sparing diuretic with a thiazide to support fluid control. You can access this product with US delivery from Canada, and this page explains access options, including paying without insurance.
What Aldactazide Is and How It Works

Spironolactone antagonizes aldosterone in the distal nephron to reduce sodium and water reabsorption while conserving potassium. Hydrochlorothiazide inhibits sodium-chloride transport in the distal tubule, increasing urine output. Together, the combination supports fluid balance and helps lower blood pressure. Formulations such as Spironolactone/Hydrochlorothiazide 25/25 mg tablets may be selected based on clinical need and tolerability. Always follow the approved label and your prescriber’s directions.
Who It’s For
This treatment is used for adults with essential Hypertension when a fixed-dose diuretic combination is appropriate. It is also indicated for edema related to congestive heart failure, hepatic cirrhosis, or nephrotic syndrome when an aldosterone antagonist is desired. People with hyperkalemia, Addison’s disease, anuria, or severe renal impairment should not use this medicine. Those with a history of sulfonamide allergy may react to hydrochlorothiazide. Suitability requires review of kidney function, electrolytes, and concurrent therapies.
Dosage and Usage
Dosing is individualized by the prescriber. The tablet is usually taken once daily in the morning; some patients may require a different schedule. Take with food if stomach upset occurs, and swallow tablets whole with water. Maintain consistent timing each day. Do not change your regimen without medical guidance. Avoid high-potassium salt substitutes unless instructed otherwise. Follow the monitoring plan for electrolytes and kidney function provided by your prescriber.
Strengths and Forms
Fixed-dose oral tablets are commonly supplied in the following strengths:
- 25/25 mg tablets
- 50/50 mg tablets
Availability can vary by manufacturer and by pack size. The pharmacy will dispense a product that matches your valid prescription.
Missed Dose and Timing
If a dose is missed, take it the same day when remembered. Skip the missed dose if it is close to the next scheduled time. Do not double doses. Because it increases urination, a morning dose is typically preferred to limit nighttime bathroom trips. Consistent daily use supports long-term blood pressure goals.
Storage and Travel Basics
Store tablets at room temperature in a dry place, protected from heat and light. Keep medicine in the original, child-resistant container. Do not store in a bathroom. For travel, carry your prescription-labeled bottle in hand luggage and bring a copy of the prescription. Use a simple pill organizer for short trips, and keep the labeled container for reference. Keep out of reach of children and pets.
Benefits
This combination provides complementary diuretic actions in a single tablet. It can help lower blood pressure while reducing the risk of potassium loss seen with some diuretics. Using one product may simplify regimens compared with separate agents. Regular use may lessen ankle swelling, abdominal fluid, or other edema-related symptoms when part of an overall care plan. Many patients find a morning routine practical.
Side Effects and Safety
- Increased urination
- Dizziness or lightheadedness
- Nausea or abdominal discomfort
- Headache or fatigue
- Muscle cramps
- Breast tenderness or gynecomastia
- Menstrual irregularities
- Rash or photosensitivity
Serious effects can include hyperkalemia, severe hyponatremia, marked hypotension, dehydration, kidney dysfunction, or hypersensitivity reactions. Seek urgent care for fainting, severe weakness, irregular heartbeat, or swelling of the face or throat. Diuretics can affect glucose control and interact with diabetes medicines; monitoring may be needed. Many patients undergo periodic checks of potassium and creatinine as part of safe use.
Drug Interactions and Cautions
Concomitant use with potassium supplements, potassium-sparing agents, ACE inhibitors, ARBs, or trimethoprim can increase potassium. NSAIDs may blunt diuretic response and affect renal function. Thiazides can raise lithium levels; close monitoring is required if used together. Electrolyte shifts may influence digoxin response. Alcohol and other antihypertensives can add to blood pressure lowering. Avoid potassium-containing salt substitutes unless directed. Patients with gout, lupus, kidney disease, or liver disease require careful evaluation. These cautions are common in Cardiovascular Disease management.
What to Expect Over Time
Urination often increases after starting and then stabilizes with regular use. Blood pressure may improve when the medicine is taken consistently and paired with lifestyle measures. Some patients need laboratory monitoring and regimen adjustments, based on clinical assessment. Keeping a simple log of home readings, if recommended, can help guide visits. For additional context on hypertension care, see Atenolol And Hypertension.
Compare With Alternatives
Alternatives include single-agent thiazides or other combination therapies. For patients needing a thiazide alone, Hydrochlorothiazide is a well-established option. When an ACE inhibitor plus thiazide is appropriate, Ramipril Hctz may be considered. Selection depends on blood pressure targets, comorbidities, laboratory values, and prior response as assessed by the prescriber.

Availability and Substitutions
Stock can vary by manufacturer and tablet count. If a specific presentation is unavailable, a prescriber may recommend an appropriate therapeutic alternative. We provide Spironolactone HCTZ Canadian pricing references so you can compare options when discussing choices with a clinician. Final dispensing depends on a valid prescription and pharmacy supply.
Patient Suitability and Cost-Saving Tips
Candidates often include adults with hypertension or edema who benefit from a potassium-sparing component. Not all patients are appropriate, particularly those with marked hyperkalemia or severe renal dysfunction. For budgeting, Spironolactone HCTZ self-pay planning may benefit from multi-month fills when allowed. Ask the prescriber about quantity limits and timing for refills. Choosing generics, coordinating lab work with routine visits, and avoiding missed doses can help manage overall costs.
Questions to Ask Your Clinician

How does this combination affect potassium levels?
The product contains spironolactone, which blocks aldosterone and can raise serum potassium. Hydrochlorothiazide tends to lower potassium, so the fixed combination may balance effects in many patients. However, hyperkalemia can still occur, especially with kidney impairment, potassium supplements, ACE inhibitors, ARBs, or trimethoprim. Periodic blood tests for potassium and creatinine are common. Report symptoms like muscle weakness or irregular heartbeat. Do not start salt substitutes that contain potassium unless your prescriber has advised it.
Can people with kidney problems take this medicine?
Caution is required in renal impairment. The combination can increase potassium and may reduce kidney function in susceptible patients. People with anuria or severe renal impairment should not use it. Those with mild to moderate impairment may require closer monitoring, slower titration, or an alternative treatment. Prescribers often check baseline and follow-up labs, including potassium and creatinine, and review other medicines that affect the kidneys. Use is individualized based on risk, benefit, and response.
What foods or supplements should be avoided?
Avoid potassium-rich salt substitutes unless specifically instructed. Use caution with high-potassium supplements or herbal products that alter electrolytes. Alcohol may enhance blood pressure lowering and dizziness. Licorice can affect potassium and should be avoided. NSAIDs can blunt diuretic response and affect kidney function; discuss occasional use. Maintain a balanced diet unless a clinician recommends a specific plan. Hydration should be steady unless you were given different directions.
Is it safe during pregnancy or breastfeeding?
The safety profile in pregnancy is not fully established. Thiazides are generally not first-line during pregnancy, and spironolactone has antiandrogen effects. Prescribers may consider alternatives if treatment is needed. For breastfeeding, small amounts of thiazides can appear in milk and may affect milk production; spironolactone metabolites may also be present. Decisions depend on clinical need and potential risk to the infant. Discuss individualized options with a healthcare professional.
Can the tablets be split or crushed?
Follow the product’s specific label. Many generics are scored and may be split if a prescriber directs a partial tablet dose. Crushing can alter how the medicine is absorbed or tolerated and is generally discouraged without guidance. If swallowing tablets is difficult, ask about alternative strengths or different therapies. Pharmacists can advise whether a particular manufacturer’s product is suitable for splitting based on its design.
What monitoring is commonly recommended?
Clinicians often check blood pressure, electrolytes (especially potassium and sodium), and kidney function at baseline and periodically. Monitoring frequency depends on kidney health, other medicines, and stability of readings. Lab checks are more frequent when treatment starts, changes, or when interacting medicines are added. Report symptoms like dizziness, muscle weakness, or irregular heartbeat. Bring a current medication list, including supplements, to appointments to support safe review.
What if the diuretic effect feels too strong?
Contact a clinician if you experience excessive urination, dizziness, or signs of dehydration. Do not change the dose on your own. The prescriber may review timing, other medicines, fluid intake, and laboratory results to adjust therapy if needed. Some people benefit from taking the dose earlier in the day. Severe symptoms like fainting, confusion, or an irregular heartbeat require urgent evaluation. Keep track of daily weights if edema is being monitored.
