POTASSIUM
Major DepletionDIURETIC DRUGS
Potassium is a mineral your heart, muscles, and nerves depend on to work properly, and indapamide can cause your kidneys to flush out more of it than usual in your urine. Because this is rated a major depletion, low potassium is a real concern for most people on this medication long-term, not just a theoretical one. Your doctor will likely want to check your potassium level with a blood test, and some people do need a supplement or dietary changes to keep levels in a healthy range. Please talk with your pharmacist or prescriber before adding any potassium supplement on your own.
What Potassium does & food sources
Potassium keeps nerve signals, muscle contractions, and heart rhythm working normally.
Common food sources:
- Bananas and citrus fruits
- Potatoes and sweet potatoes
- Beans and lentils
- Tomatoes and leafy greens
HelloPharmacist pharmacist-reviewed education — separate from the licensed record above.
What to discuss with your clinician
Potassium is routinely checked with basic blood work. If you take a medication associated with potassium loss (like some diuretics), ask your provider how often your electrolytes should be monitored.
HelloPharmacist pharmacist-reviewed education — separate from the licensed record above.
Supplement considerations
Do not start potassium supplements on your own. Both low and high potassium can affect heart rhythm, and several common medications (ACE inhibitors, ARBs, potassium-sparing diuretics) raise potassium.
Do not start or stop medications or supplements without professional guidance — supplements can interact with prescription medications.

VITAMIN C
Insignificant DepletionDIURETIC DRUGS
In people with chronic renal failure, a 20 mg intravenous dose of furosemide (Lasix) increases urinary losses of vitamin C, probably due to increased water excretion. Significant vitamin C depletion hasn't been reported with long-term oral use of furosemide or other diuretics.
Vitamin C is something your immune system, skin, and wound healing all depend on, so it is worth knowing that diuretics like indapamide can, in theory, cause a little more of it to leave the body through urine simply because these medications increase how much water the kidneys flush out. That said, real vitamin C depletion from oral diuretics has not been reported in practice, and this interaction is rated as insignificant for most people. No extra supplement is needed for the typical indapamide user, but if you have concerns or eat a diet low in fruits and vegetables, a quick chat with your pharmacist is always a reasonable step.
What Vitamin C does & food sources
Vitamin C is an antioxidant that supports the immune system, collagen formation, and iron absorption.
Common food sources:
- Citrus fruits
- Bell peppers
- Strawberries and kiwi
- Broccoli and Brussels sprouts
HelloPharmacist pharmacist-reviewed education — separate from the licensed record above.
What to discuss with your clinician
Frank vitamin C deficiency is uncommon with a varied diet. If your diet is limited and you take an associated medication, ask your provider whether your intake is adequate.
HelloPharmacist pharmacist-reviewed education — separate from the licensed record above.
Supplement considerations
Vitamin C is water-soluble and generally low-risk at food-level intakes; very high supplemental doses can cause stomach upset and may not add benefit.
Do not start or stop medications or supplements without professional guidance — supplements can interact with prescription medications.

MAGNESIUM
Moderate DepletionDIURETIC DRUGS
Loop diuretics and, to a lesser extent thiazide diuretics, interfere with magnesium reabsorption in the kidneys, increasing urinary losses and reducing serum magnesium levels. Potassium-sparing diuretics, such as amiloride, triamterene, or spironolactone, are also magnesium-sparing, and can therefore counteract the magnesium losses seen with loop diuretics and thiazides. For information on foods that are rich in magnesium, see our chart.
Magnesium is a mineral your muscles, nerves, and heart rhythm depend on, and indapamide can gradually chip away at your levels by causing your kidneys to flush more of it out in the urine than usual. Indapamide is a thiazide-like diuretic, and this type of water pill reduces how well the kidneys hold onto magnesium, so it gets lost rather than recycled. Because this is rated a moderate depletion, it is something worth paying attention to over the long term, especially if you take indapamide every day. Ask your pharmacist or doctor whether checking your magnesium level makes sense for you, since some people do end up needing a supplement.
What Magnesium does & food sources
Magnesium is involved in muscle and nerve function, heart rhythm, blood sugar control, and bone health.
Common food sources:
- Nuts and seeds (almonds, pumpkin seeds)
- Whole grains
- Leafy green vegetables
- Beans and legumes
HelloPharmacist pharmacist-reviewed education — separate from the licensed record above.
What to discuss with your clinician
Ask whether a magnesium level is worth checking if you take an associated medication long-term — particularly with symptoms like muscle cramps, twitching, or palpitations. Blood levels do not always reflect total body stores, which is worth discussing too.
HelloPharmacist pharmacist-reviewed education — separate from the licensed record above.
Supplement considerations
Magnesium supplements come in many forms and can cause loose stools at higher doses. They can also bind some medications in the gut (certain antibiotics, thyroid medication), so timing matters — check with your pharmacist.
Do not start or stop medications or supplements without professional guidance — supplements can interact with prescription medications.
HelloPharmacist pharmacist-reviewed education — separate from the licensed record above.
Caution: Magnesium supplementation can be risky in kidney disease, where magnesium can accumulate — always check with a clinician first if your kidney function is reduced.

THIAMINE
Moderate DepletionDIURETIC DRUGS
Increased urinary thiamine excretion and thiamine deficiency may occur in some people treated with diuretics, especially in high doses (e.g., more than 80 mg furosemide daily) for several months. Although most case reports involve furosemide, animal data suggest that the effect may occur with any diuretic. Diuretic-induced thiamine deficiency appears to be most common in elderly people with inadequate dietary intake and to be rare in people less than 60 years of age. Thiamine deficiency in people taking diuretics is a concern because it might worsen heart failure. Limited research suggests that supplementation with thiamine 200 mg daily may improve left ventricular ejection fraction and functional capacity in some thiamine-deficient people treated with high doses of furosemide for heart failure. However, other studies have found no improvement. It's too soon to recommend routine thiamine supplementation for people on prolonged, high-dose diuretic therapy. Monitor for thiamine deficiency.
Thiamine is a B vitamin your heart and nerves depend on to turn food into usable energy. Indapamide is a diuretic, meaning it makes your kidneys remove more fluid through urine, and thiamine can get flushed out along with that extra fluid. This is rated moderate, so it is a real consideration, particularly for older adults or anyone who has been on a diuretic for a long time and eats a limited diet. It is worth bringing up with your pharmacist or doctor, especially if you have heart concerns.
What Vitamin B1 (thiamine) does & food sources
Thiamine helps convert food into energy and is essential for nerve and heart function.
Common food sources:
- Whole grains and fortified cereals
- Pork
- Beans and lentils
- Nuts and seeds
HelloPharmacist pharmacist-reviewed education — separate from the licensed record above.
What to discuss with your clinician
Ask about thiamine if you take an associated medication (for example, a long-term loop diuretic in heart failure) and have symptoms like fatigue or worsening heart failure control — this is an area your care team can weigh.
HelloPharmacist pharmacist-reviewed education — separate from the licensed record above.
Supplement considerations
Thiamine is water-soluble and generally low-risk, but supplementing to treat a suspected problem should still be clinician-guided so the real cause is not missed.
Do not start or stop medications or supplements without professional guidance — supplements can interact with prescription medications.

ZINC
Moderate DepletionTHIAZIDE DIURETICS
Clinical research shows that thiazide diuretics increase urinary zinc excretion by 50% to 60%, and this is likely sustained during at least 3 years of treatment. Decreased serum zinc levels sometimes occur, although they usually remain within the normal range, possibly due to compensatory mechanisms. However, prolonged thiazide therapy might deplete tissue zinc. It's suggested this could contribute to the impotence sometimes seen with thiazides. Monitor patients on long-term thiazide therapy for symptoms of zinc deficiency. Amiloride is zinc-sparing and can counteract zinc losses caused by thiazides.
Zinc is a mineral your immune system, wound healing, and hormone function all depend on. Indapamide belongs to the thiazide diuretic family, and these medications cause the kidneys to flush significantly more zinc out through the urine than usual. Blood zinc levels often stay within the normal range because the body tries to compensate, but long-term use may quietly draw down zinc stored in tissues. If you have been on indapamide for a while, it is worth asking your pharmacist or doctor whether monitoring or a supplement makes sense for you.
What Zinc does & food sources
Zinc supports immune function, wound healing, taste and smell, and many enzyme systems.
Common food sources:
- Meat and shellfish (especially oysters)
- Beans and lentils
- Nuts and seeds
- Whole grains
HelloPharmacist pharmacist-reviewed education — separate from the licensed record above.
What to discuss with your clinician
Ask about zinc status if you take an associated medication long-term and notice slow wound healing, frequent infections, or taste changes — a clinician can decide whether testing or an empiric plan makes sense.
HelloPharmacist pharmacist-reviewed education — separate from the licensed record above.
Supplement considerations
Zinc competes with copper for absorption — long-term, higher-dose zinc without medical guidance can cause copper deficiency. Zinc also binds some antibiotics in the gut, so dose timing matters.
Do not start or stop medications or supplements without professional guidance — supplements can interact with prescription medications.
HelloPharmacist pharmacist-reviewed education — separate from the licensed record above.
Caution: Keep zinc doses moderate and time them away from interacting medications — ask your pharmacist.

COENZYME Q10
Insufficient EvidenceANTIHYPERTENSIVE DRUGS
Some antihypertensive drugs, including beta blockers, diazoxide, hydralazine, and others, appear to inhibit coenzyme Q10 enzyme activity and may decrease endogenous levels of coenzyme Q10. However, it is not clear if this reduction is clinically significant. There is no reliable evidence that coenzyme Q10 depletion contributes to antihypertensive drug side effects.
Coenzyme Q10 is a natural compound your body makes that helps cells produce energy and may support heart muscle function. Some blood pressure medications have been linked to lower CoQ10 activity, possibly by interfering with the enzymes your body uses to make it, though whether indapamide specifically does this is not well studied. The evidence here is genuinely thin, so there is no need to worry or act on this right now. If you are curious whether a CoQ10 supplement makes sense for you, it is worth a quick conversation with your pharmacist or doctor.
What Coenzyme Q10 (CoQ10) does & food sources
CoQ10 helps cells produce energy and acts as an antioxidant; heart and muscle tissue use it heavily.
Common food sources:
- Organ meats and fatty fish
- Whole grains
- Nuts and seeds
HelloPharmacist pharmacist-reviewed education — separate from the licensed record above.
What to discuss with your clinician
There is no routine blood test for CoQ10 in everyday practice. If you have new, unexplained muscle symptoms on a medication linked to CoQ10 (statins are the best-known example), talk to your prescriber before changing anything — symptoms have many possible causes and your prescriber has several options.
HelloPharmacist pharmacist-reviewed education — separate from the licensed record above.
Supplement considerations
CoQ10 is generally well tolerated, but evidence for supplementing (for example, for statin muscle symptoms) is mixed. It may also modestly affect warfarin — check with your pharmacist before combining.
Do not start or stop medications or supplements without professional guidance — supplements can interact with prescription medications.

FOLIC ACID
Insufficient EvidenceDIURETIC DRUGS
Limited data suggests diuretics may increase excretion of folic acid. Reduced red blood cell folate levels, possibly contributing to increased homocysteine levels, were found in one group of people taking diuretics for six months or longer. The need for folic acid supplementation during diuretic therapy hasn't been adequately studied. Advise patients to maintain a good dietary intake of folic acid. For information on foods that are rich in folate, see our chart.
Folic acid is a B vitamin your body uses to build healthy red blood cells and keep homocysteine, a chemical linked to heart health, in a normal range. Indapamide is a diuretic, meaning it nudges your kidneys to pass more fluid, and there is some early evidence that diuretics may cause the body to flush out a bit more folate along with that fluid. That said, the research here is quite limited, and we honestly do not know whether this matters much in everyday life. Eating folate-rich foods like leafy greens, beans, and fortified cereals is a reasonable habit for anyone on a long-term diuretic, and if you have concerns, your pharmacist or doctor can talk through whether anything more is needed.
What Folic acid (folate) does & food sources
Folate is needed for cell division, red blood cell formation, and healthy fetal development.
Common food sources:
- Leafy green vegetables
- Beans, lentils, and peas
- Fortified grains and cereals
- Citrus fruits
HelloPharmacist pharmacist-reviewed education — separate from the licensed record above.
What to discuss with your clinician
Ask your provider whether folate monitoring or supplementation is appropriate for you — this matters most before and during pregnancy, and with long-term use of certain seizure or arthritis medications.
HelloPharmacist pharmacist-reviewed education — separate from the licensed record above.
Supplement considerations
Folate needs are individual. With some medications (for example, methotrexate), folic acid is often prescribed deliberately on a specific schedule — follow your prescriber's instructions rather than adding your own.
Do not start or stop medications or supplements without professional guidance — supplements can interact with prescription medications.

Caution: High-dose folic acid can mask vitamin B12 deficiency, so the two are often evaluated together.

SODIUM
Insufficient EvidenceDIURETIC DRUGS
Loop and thiazide diuretics increase sodium excretion by preventing sodium from being reabsorbed by the kidneys. Although uncommon, loop or thiazide diuretics can cause severe hyponatremia in some patients.
Sodium keeps your fluid balance, blood pressure, and nerve signals working properly, so your body guards it carefully. Indapamide is a thiazide-like diuretic, meaning it works in the kidneys to push more sodium out through your urine, which is actually part of how it lowers blood pressure. The evidence here is rated insufficient, so we do not know how clinically meaningful this is for most people, though low sodium has been reported with this class of drug in some cases. If you feel unusually fatigued, nauseated, or confused while taking indapamide, that is worth mentioning to your pharmacist or doctor.
What Sodium does & food sources
Sodium maintains fluid balance, blood pressure, and nerve/muscle function.
Common food sources:
- Table salt and most processed foods — dietary shortage is rare; medication-related loss is about balance, not intake
HelloPharmacist pharmacist-reviewed education — separate from the licensed record above.
What to discuss with your clinician
Sodium is part of routine blood work. If you take an associated medication (like certain diuretics or antidepressants), ask how often your electrolytes should be checked — especially if you feel confused, weak, or unusually tired.
HelloPharmacist pharmacist-reviewed education — separate from the licensed record above.
Supplement considerations
Low sodium from a medication is managed by your care team (often by adjusting the medication or fluids) — not by eating more salt on your own.
Do not start or stop medications or supplements without professional guidance — supplements can interact with prescription medications.

More about Indapamide
What drug-induced nutrient depletion means
Some medications can, over time, lower the levels of certain vitamins, minerals, or other nutrients — through reduced absorption, increased loss, or changes in how the body uses them.
Association is not deficiency
An entry here means a depletion has been reported or studied — not that it happens to everyone, or that you are deficient. Dose, duration, diet, and your own health all matter.
Evidence varies by pair
Some drug–nutrient links (like metformin and vitamin B12) are well studied; others rest on limited or preliminary research. Each entry shows the evidence rating from our licensed clinical database.
When to ask about labs
If you take an associated medication long-term, ask your healthcare provider whether monitoring is appropriate for you. Not everyone needs testing — your provider can weigh your dose, duration, and symptoms.
Don't self-supplement blindly
Supplements are not risk-free: some can interact with medications, and some (like potassium or magnesium) can be risky with kidney disease. Talk to your pharmacist before adding anything.
Never stop a medication over this
These medications are prescribed for good reasons, and the benefit usually far outweighs a manageable nutrient consideration. Any change belongs in a conversation with your prescriber.
Food first, usually
For many nutrients, a varied diet covers the gap. Each entry lists common food sources; a supplement is a decision to make with your pharmacist or provider, not a default.
