Hydroxychloroquine and Potassium: what the published research says

PubMed indexes 6 records that name Hydroxychloroquine and Potassium together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.

Read this first

An evidence index, not guidance.

Every statement below is attributed to a named, dated, linked source.

This page lists published research relevant to Hydroxychloroquine and Potassium. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.

The research

6 studies naming Hydroxychloroquine and Potassium.

Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.

Renal potassium wasting from hydroxychloroquine at therapeutic doses: a case report.

BMC nephrology · 2026 · PMID 41593546

Case ReportsHuman subjects

“The underlying mechanism remains uncertain and is hypothesized to involve tubular effects during chronic exposure. Clinicians should confirm the mechanism with urine studies when hypokalemia persists on hydroxychloroquine, consider a supervised medication hold when feasible, and pair potassium repletion with a potassium-sparing agent if the drug must continue.”

Tse et al. · From the abstract

Names both Hydroxychloroquine and Potassium in its title.

A case analysis of Gitelman syndrome complicated with Sjögren's disease.

Frontiers in medicine · 2026 · PMID 42404579

Case Reports

“In Sjögren's disease patients with refractory hypokalemia, underlying hereditary renal tubular disorders should be suspected. Combining immunological evaluation with genetic testing is crucial to ensure accurate diagnosis and optimize management.”

Tang et al. · Authors' conclusion

Names Hydroxychloroquine and Potassium together in an interaction, co-administration, or pharmacokinetic context.

Limitations

What this evidence cannot tell you.

Search-based evidence indexes have real limits, and it is worth being explicit about them:

Track what you actually take.

NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers Hydroxychloroquine, Potassium, and several hundred other substances.

The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
