Sugar Busters Diet and Diltiazem

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

Worth understanding: our licensed dataset holds no drug-interaction record for Sugar Busters Diet at all — not against Diltiazem, 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.

Sugar Busters 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.

Sugar Busters Diet safety at a glance

What Diltiazem’s Own FDA Label Lists

This is not an interaction — none of it involves Sugar Busters Diet. These are the most notable effects listed in the ADVERSE REACTIONS section of Diltiazem’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 Sugar Busters Diet and take the medicine. 10 of them are worth acting on rather than waiting out — marked below.

  • Bleeding in the gut Worth acting on
  • A slow heartbeat Worth acting on
  • Shortness of breath Worth acting on mentioned in 9.6% of FDA reports for Diltiazem
  • Fainting Worth acting on
  • An irregular heartbeat Worth acting on
  • A severe skin reaction Worth acting on
  • Chest pain Worth acting on
  • Kidney problems Worth acting on
  • Raised blood pressure Worth acting on
  • Hives Worth acting on

Showing the 10 most notable of 41 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 Diltiazem. Read the label on DailyMed › Where a percentage is shown, it is the share of 34,400 voluntary FDA FAERS reports for Diltiazem that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Sugar Busters Diet’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Sugar Busters Diet side to compare — that is a limit of the record, not a statement that Sugar Busters Diet has no side effects.

From our pharmacist’s overview on the Diltiazem page

“Someone on diltiazem (Cardizem, Tiazac) is usually managing blood pressure, angina, or a fast heart rhythm, so this list deserves genuine care. Seven of the 260 ingredients on file carry a major rating, and two of those are things people actually buy: grapefruit, which blocks the enzyme that clears diltiazem and can push its blood leve…”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Sugar Busters 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 Sugar Busters Diet reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Sugar Busters Diet and Diltiazem 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 Sugar Busters Diet

What is Sugar Busters Diet?

  • Weight loss
  • Blood sugar control
  • Type 2 diabetes management
  • Lowering cholesterol and triglycerides
  • Reducing refined sugar intake

The Sugar Busters Diet is an eating plan, not a herb or supplement. It encourages cutting refined sugar and high-glycemic carbohydrates while focusing on lean proteins, whole grains, vegetables, and healthy fats. It may help some people lose weight and improve blood sugar, but it works mainly because it cuts calories and refined carbs—talk to your doctor or dietitian before starting any new diet.

Books, meal plans, low-glycemic food choices

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

Sugar Busters Diet: dosing

There is no "dose" for the Sugar Busters Diet because it is an eating pattern, not a pill. Instead, people follow the plan's guidelines on which foods to choose and which to limit, focusing on low-glycemic, whole foods.The healthiest approach is to aim for balanced meals with vegetables, lean protein, healthy fats, and high-fiber whole grains, while limiting added sugar and refined carbs.

Brand names: Cardizem, Cardizem SR, Diltiaz SR, Cardizem CD, Tiazac, Diltiaz XT, Diltiaz CD, Dilacor, Diltiaz, Cardizem LA, Dilacor XR, Cartia XT, Tiamate, Adizem-SR, Adizem-XL, Angitil SR, Angitil XL, Calcicard CR, Dilcardia SR, Dilzem SR, Dilzem XL, Slozem, Tildiem LA, Tildiem Retard, Viazem XL, Zemtard 120XL, Zemtard 180XL, Zemtard 240XL, Zemtard 300XL

Oral extended-release forms of diltiazem — including Matzim LA, Cardizem LA, Cartia, Cartia XT, Tiadylt ER, and various generic capsules and tablets — are used to treat high blood pressure (hypertension) and chronic stable angina (chest pain brought on by activity). Some capsule formulations, including Cartia, Cartia XT, and certain generics, are also approved for angina due to coronary artery spasm (sudden chest pain caused by a sudden tightening of a coronary artery).

Injectable forms of diltiazem are used in hospital settings to temporarily slow a dangerously fast heart rate in atrial fibrillation or atrial flutter (rapid, irregular heart rhythms), and to restore a normal heart rhythm in paroxysmal supraventricular tachycardia (PSVT) — sudden episodes of a very fast but regular heartbeat originating above the heart's lower chambers.

Most-Reported Side Effects for Diltiazem

From FAERS, the FDA’s public side-effect reporting system (34,400 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Dyspnea 3,309 reports
Fatigue 2,733 reports
Nausea 2,454 reports
