South Beach Diet + Allopurinol
Allopurinol brand names: Zyloprim, Caplenal, Cosuric, Rimapurinol, Zyloric.
We found no known interaction between South Beach Diet and Allopurinol 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. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.
South Beach Diet and Allopurinol
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 Allopurinol and South Beach Diet in our sources. This does not guarantee that the combination is completely free of risk — research on South Beach Diet alongside specific medications may be limited.
Worth understanding: our licensed dataset holds no drug-interaction record for South Beach Diet at all — not against Allopurinol, 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.
South Beach 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.

From our pharmacist’s overview on the Allopurinol page
“Allopurinol (Zyloprim) prevents gout attacks by lowering uric acid, and I would give this list real weight, because 5 of the 60 supplements and herbs on file carry a major rating. The largest cluster, 38 ingredients, is products that can stress the liver on their own, and regular beer or wine sits in that major group, since alcohol on…”

About South Beach Diet
What is South Beach Diet?
- Weight loss
- Blood sugar control
- Reducing cravings for refined carbs
- Improving cholesterol and heart health
- General healthy eating
The South Beach Diet is a popular low-glycemic, higher-protein eating plan—not an herb or supplement. It can help some people lose weight and reduce refined-carb cravings, especially in the short term, but long-term success depends on sticking with healthy habits. Talk to your doctor or a dietitian before starting any restrictive diet, particularly if you have diabetes, kidney disease, or take medications.
Structured eating plan with three phases; books, prepackaged meals, and meal-delivery programs
An interaction check asks whether these two react with each other — it does not ask whether South Beach Diet is a good idea for someone in your situation. Here is what our South Beach Diet record says about it on its own.
South Beach Diet: dosing
There is no "dose" because the South Beach Diet is an eating plan, not a pill or supplement. Instead, you follow the structure of its phases and food lists as described in the official books or program materials.If you choose a prepackaged meal version, follow the program's serving guidance.

About Allopurinol
What Is Allopurinol Used For?
Brand names: Zyloprim, Caplenal, Cosuric, Rimapurinol, Zyloric
Allopurinol tablets (including Zyloprim) are used in adults to treat the signs and symptoms of gout — including gout attacks, tophi (uric acid deposits), joint damage, and kidney problems caused by uric acid. Allopurinol tablets are also used in adults to reduce recurrent calcium oxalate kidney stones when uric acid in the urine is too high, even after lifestyle changes.
For adults and children with leukemia, lymphoma, or solid tumor cancers, allopurinol is used to control uric acid levels that rise during cancer treatment. The injectable forms — Allopurinol sodium for injection and Aloprim — are specifically for patients who cannot take medicine by mouth and are given intravenously (through a vein) in a hospital or clinical setting. Note: allopurinol tablets are not recommended for people who have high uric acid levels but no symptoms.
