The bottom line No known interaction

We found no known interaction between Low Purine Diet and Hydroxyurea in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.

Low Purine Diet and Hydroxyurea

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 Hydroxyurea and Low Purine Diet in our sources. This does not guarantee that the combination is completely free of risk — research on Low Purine Diet alongside specific medications may be limited.

Worth understanding: our licensed dataset holds no drug-interaction record for Low Purine Diet at all — not against Hydroxyurea, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

Low Purine 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.

What Hydroxyurea’s Own FDA Label Lists

This is not an interaction — none of it involves Low Purine Diet. These are the most notable effects listed in the ADVERSE REACTIONS section of Hydroxyurea’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 Low Purine Diet and take the medicine. 6 of them are worth acting on rather than waiting out — marked below.

  • Low magnesium Worth acting on
  • Anemia Worth acting on mentioned in 12.0% of FDA reports for Hydroxyurea
  • A low platelet count Worth acting on
  • Shortness of breath Worth acting on
  • A low white blood cell count Worth acting on
  • A higher chance of infection Worth acting on
  • Changes to your period
  • Dry skin
  • Weight gain
  • Pain in an arm or leg

Showing the 10 most notable of 25 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 Hydroxyurea. Read the label on DailyMed › Where a percentage is shown, it is the share of 21,027 voluntary FDA FAERS reports for Hydroxyurea that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Low Purine Diet’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Low Purine Diet side to compare — that is a limit of the record, not a statement that Low Purine Diet has no side effects.

Everything else you take

See Every Supplement That Interacts With Hydroxyurea

This page covers Low Purine Diet only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Hydroxyurea page lists 18 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Coffee Charcoal (moderate), European Mandrake (moderate), Glucomannan (moderate) and Guar Gum (moderate).

By severity: 1 major · 7 moderate · 10 minor.

From our pharmacist’s overview on the Hydroxyurea page

“People take hydroxyurea (Droxia, Hydrea, Siklos, Xromi) for serious reasons, most often sickle cell disease or certain blood cancers, and it only works if a steady dose reaches the bloodstream. That is exactly what nearly all 18 supplements listed here can undermine, so this page earns real vigilance rather than a skim.”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Low Purine Diet is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Low Purine Diet reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 13, 2026. The Low Purine Diet and Hydroxyurea records this page draws on were last updated June 22, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Low Purine Diet

What is Low Purine Diet?

  • Gout management
  • Lowering uric acid levels
  • Preventing kidney stones (uric acid stones)
  • Reducing gout flare-ups

A low purine diet is an eating plan that limits foods high in purines, which the body breaks down into uric acid. It is mainly used to help manage gout and certain kidney stones, often alongside medication. While it can lower uric acid somewhat, diet alone usually is not enough for most people with gout, so work with your doctor on a full treatment plan.

Dietary pattern (meal plan), not a supplement

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

Low Purine Diet: dosing

There is no fixed "dose" for a low purine diet because it is an eating pattern, not a pill. In general, the goal is to limit high-purine foods (organ meats, red meat, certain seafood, beer, and sugary drinks) while eating more vegetables, fruits, whole grains, and low-fat dairy.Drinking plenty of water and limiting alcohol are also key parts of the plan.
