Weight Watchers Diet and Indapamide

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Indapamide and Weight Watchers Diet in our sources. This does not guarantee that the combination is completely free of risk — research on Weight Watchers Diet alongside specific medications may be limited.

Weight Watchers Diet is an eating pattern rather than something you take. Ask your pharmacist or doctor before changing how you eat while on a prescribed medicine: some medicines are dosed around meals, and a change in diet can change how they work. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

How we checked

Why No Interaction Is Listed for Indapamide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Indapamide is filed under 5 classifications — including thiazide diuretics, diuretic drugs, qt interval-prolonging drugs. Weight Watchers Diet has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — and none of Indapamide’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

What Indapamide’s Own FDA Label Lists

This is not an interaction — none of it involves Weight Watchers Diet. These are the most notable effects listed in the ADVERSE REACTIONS section of Indapamide’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you follow Weight Watchers Diet and take the medicine. 8 of them are worth acting on rather than waiting out — marked below.

  • Low sodium Worth acting on mentioned in 7.4% of FDA reports for Indapamide
  • Low potassium Worth acting on
  • High blood sugar Worth acting on
  • Chest pain Worth acting on
  • Low mood Worth acting on
  • Hives Worth acting on
  • A higher chance of infection Worth acting on
  • An allergic reaction Worth acting on
  • A change in sex drive
  • Passing urine more often

Showing the 10 most notable of 40 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Indapamide. Read the label on DailyMed › Where a percentage is shown, it is the share of 17,821 voluntary FDA FAERS reports for Indapamide that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Weight Watchers Diet’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Weight Watchers Diet side to compare — that is a limit of the record, not a statement that Weight Watchers Diet has no side effects.

Everything else you take

See Every Supplement That Interacts With Indapamide

This page covers Weight Watchers Diet only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Indapamide page lists 215 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), American Hellebore (major), American Mistletoe (major), Arsenic (major) and Cesium (major).

From our pharmacist’s overview on the Indapamide page

“A water pill like indapamide (Lozol) lowers blood pressure and pulls potassium down, and most of the 215 supplements and herbs on file press on those same levers. Thirteen entries rate major, so this is a list to read with real care rather than skim.”

About Weight Watchers Diet

What is Weight Watchers Diet?

  • Weight loss
  • Weight maintenance
  • Building healthier eating habits
  • Behavioral support for diet change
  • General wellness and lifestyle improvement

Weight Watchers (now called WW) is a commercial weight-loss program built around a points system, food tracking, and group or online support rather than a pill or herbal product. Research generally shows it can help people lose a modest amount of weight and keep some of it off, especially when combined with regular activity. Talk with your doctor or pharmacist before starting any weight-loss plan, particularly if you have a medical condition.

Not applicable (this is a commercial weight-management program, not a plant or supplement) · Structured eating plan with a points-based food system, app, group or online support, and coaching

An interaction check asks whether these two react with each other — it does not ask whether Weight Watchers Diet is a good idea for someone in your situation. Here is what our Weight Watchers Diet record says about it on its own.

Weight Watchers Diet: dosing

There is no pill or standardized dose for Weight Watchers, since it is a behavioral eating program. Instead, you follow the program's points budget and tracking system as set up in the app or plan you select.The right calorie or points target depends on your age, sex, weight, activity level, and goals, and the program personalizes this for you.

About Indapamide

What Is Indapamide Used For?

Brand names: Lozol, Lozide

Indapamide tablets are used to treat high blood pressure (hypertension), either on their own or together with other blood pressure medications. Lowering blood pressure helps reduce the risk of related complications.

Indapamide tablets are also used to treat salt and fluid retention (edema) associated with congestive heart failure. In certain cases, indapamide may also be appropriate during pregnancy when swelling is caused by a medical condition rather than normal pregnancy changes — but routine use in otherwise healthy pregnant women is not recommended.

Most-Reported Side Effects for Indapamide

From FAERS, the FDA’s public side-effect reporting system (17,821 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Hyponatraemia 1,318 reports
Acute kidney injury 949 reports
Dyspnea 920 reports
Dizziness 899 reports
Nausea 881 reports
