Jenny Craig Diet and Primaquine Phosphate

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 Primaquine Phosphate and Jenny Craig Diet in our sources. This does not guarantee that the combination is completely free of risk — research on Jenny Craig Diet alongside specific medications may be limited.

Worth understanding: our licensed dataset holds no drug-interaction record for Jenny Craig Diet at all — not against Primaquine Phosphate, 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.

Jenny Craig 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.

Jenny Craig Diet safety at a glance

Jenny Craig Diet overall Use caution Generally considered reasonable for healthy adults, but check with a clinician first if you have any medical condition.

What to actually watch for

What Primaquine Phosphate’s Own FDA Label Lists

This is not an interaction — none of it involves Jenny Craig Diet. These are the most notable effects listed in the ADVERSE REACTIONS section of Primaquine Phosphate’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 Jenny Craig Diet and take the medicine. 2 of them are worth acting on rather than waiting out — marked below.

  • Anemia Worth acting on
  • A low white blood cell count Worth acting on
  • Stomach pain
  • Vomiting
  • Nausea

From the ADVERSE REACTIONS section of the FDA label for Primaquine Phosphate. Read the label on DailyMed › Where a percentage is shown, it is the share of 81 voluntary FDA FAERS reports for Primaquine Phosphate that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Jenny Craig Diet’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Jenny Craig Diet side to compare — that is a limit of the record, not a statement that Jenny Craig Diet has no side effects.

Everything else you take

See Every Supplement That Interacts With Primaquine Phosphate

This page covers Jenny Craig Diet only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Primaquine Phosphate 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 Grapefruit (moderate).

By severity: 1 major · 8 moderate · 9 minor.

From our pharmacist’s overview on the Primaquine Phosphate page

“Activated charcoal, the only major-rated interaction among the 18 on file, can bind primaquine phosphate (Primaquine) in the gut and shrink how much of each dose your body actually absorbs. That matters more than usual, because this antimalarial exists to wipe out the malaria parasites hiding in the liver, and an under-absorbed course…”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Jenny Craig 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 Jenny Craig Diet reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 13, 2026. The Jenny Craig Diet and Primaquine Phosphate 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 Jenny Craig Diet

What is Jenny Craig Diet?

  • Weight loss
  • Weight management
  • Portion control
  • Building healthier eating habits
  • Support for blood sugar control through weight loss

The Jenny Craig Diet is a commercial weight-loss program, not a supplement or herb. It uses prepackaged, portion-controlled meals plus personal coaching to help people lose weight, and research generally shows structured meal-replacement programs like this can produce real short-term weight loss. Talk with your doctor or pharmacist before starting, especially if you have a medical condition.

Prepackaged meals, snacks, shakes, and a structured menu plan with personal coaching

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

Jenny Craig Diet: dosing

There is no "dose" for the Jenny Craig Diet the way there is for a supplement. Instead, the program sets a daily calorie target and menu based on factors like your weight, sex, and goals, usually using their prepackaged meals plus added produce and dairy.Follow the plan and serving guidance provided by the program, and don't drop your calories lower than recommended on your own.

About Primaquine

What Is Primaquine Used For?

Brand name: Primaquine

Primaquine Phosphate Tablets are used for the radical cure of vivax malaria — meaning they target and eliminate the dormant liver forms of the Plasmodium vivax parasite that can cause the infection to come back (relapse). This is different from treating the active blood-stage infection, which is usually handled first with another medicine like chloroquine.

Primaquine Phosphate Tablets are also used after a course of chloroquine suppressive therapy in areas where vivax malaria is common, to prevent relapse once that preventive treatment ends.
