The bottom line No known interaction

We found no known interaction between Dash Diet and Tigecycline 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.

Interaction report

Dash Diet and Tigecycline

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

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

Dash 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 Tigecycline’s Own FDA Label Lists

This is not an interaction — none of it involves Dash Diet. These are the most notable effects listed in the ADVERSE REACTIONS section of Tigecycline’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 Dash Diet and take the medicine. 5 of them are worth acting on rather than waiting out — marked below.

  • Low sodium Worth acting on
  • Pancreatitis Worth acting on
  • Anemia Worth acting on
  • A severe allergic reaction Worth acting on
  • A higher chance of infection Worth acting on mentioned in 4.5% of FDA reports for Tigecycline
  • Stomach upset
  • Stomach pain
  • Vomiting mentioned in 4.5% of FDA reports for Tigecycline
  • Tiredness
  • Dizziness

Showing the 10 most notable of 14 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 Tigecycline. Read the label on DailyMed › Where a percentage is shown, it is the share of 5,980 voluntary FDA FAERS reports for Tigecycline that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Dash Diet’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Dash Diet side to compare — that is a limit of the record, not a statement that Dash Diet has no side effects.

Special populations

Dash Diet in Pregnancy & Breastfeeding

Pregnancy Possibly Safe

When used appropriately, short-term. DASH diets have been used with apparent safety during pregnancy for 4-12 weeks. A modified DASH diet called MAMA-DASH, with adequate nutrition and calories for pregnancy, has been used for 20 weeks without reports of adverse events.

Lactation Possibly Safe

When used appropriately while breastfeeding for up to 6 months. The DASH diet is a balanced diet that is not expected to be harmful during breastfeeding. Observational research in exclusively breastfed infants has found that high adherence to the DASH diet for 4-6 months while breastfeeding is not associated with changes in infant weight, height, or head circumference when compared with low adherence to the DASH diet.

Overlapping uses

What Tigecycline Is Prescribed For, and What Dash Diet Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Tigecycline is a prescription medicine with approved uses on its FDA label. Dash Diet is an eating pattern: what follows is what researchers have looked at it for, and how strong that evidence is.

Tigecycline is prescribed for: Tygacil (tigecycline for injection) is approved for adults 18 and older to treat three types of serious bacterial infections: complicated skin and skin structure infections, complicated intra-abdominal (stomach and intestinal) infections, and community-acquired bacterial pneumonia (pneumonia caught outside a hospital). It is not approved for diabetic foot infections or for pneumonia caught in a hospital setting, including ventilator-associated pneumonia — clinical trials showed it did not work well enough for those uses and was associated with higher mortality in patients with ventilator-associated pneumonia.

  • Diabetes Natural Medicines rates the evidence for Dash Diet: Possibly Effective Read what the research shows

    Dash Diet for diabetes

    Following the DASH diet may be beneficial for the management of diabetes. The DASH diet may also be beneficial for reducing the risk of gestational and type 2 diabetes.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Tigecycline on your own; if you are taking Dash Diet for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

See Every Supplement That Interacts With Tigecycline

This page covers Dash Diet only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Tigecycline page lists 98 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Oleander (major), Para-aminobenzoic Acid (paba) (major), Acerola (moderate), Alfalfa (moderate) and Alpha-lipoic Acid (moderate).

By severity: 2 major · 88 moderate · 8 minor.

From our pharmacist’s overview on the Tigecycline page

“Tigecycline (Tygacil) is an intravenous antibiotic usually reserved for serious or resistant infections, and its supplement list deserves real attention. The two major-rated entries come first: oleander, a heart-toxic plant whose compounds may build to dangerous levels with certain antibiotics on board, and PABA, which can blunt the an…”

About Dash Diet

What is Dash Diet?

  • High blood pressure
  • Heart health
  • Lowering cholesterol
  • Weight management
  • Healthy eating pattern

The DASH (Dietary Approaches to Stop Hypertension) diet is an eating plan rich in fruits, vegetables, whole grains, and low-fat dairy, with less salt, red meat, and added sugar. It is one of the best-studied diets for lowering blood pressure and is widely recommended by doctors and dietitians. It is a food-based lifestyle plan, not a pill or supplement.

Eating pattern (whole-food diet plan)

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

Dash Diet: dosing

There is no pill or standardized "dose" for DASH, since it is an eating pattern rather than a supplement. Instead, the plan suggests target servings each day from food groups like vegetables, fruits, grains, dairy, lean protein, and a limited amount of fats and sweets.Sodium goals are usually set at a moderate level, and there is a lower-sodium version that may lower blood pressure even more. The exact amounts depend on your calorie needs, age, and health goals.A registered dietitian or your pharmacist can help you tailor the plan to your needs. Free DASH guides are also available from the NIH and National Heart, Lung, and Blood Institute.

Following Dash Diet While Taking Tigecycline: Common Questions

Is it safe to follow Dash Diet while taking Tigecycline?
We do not list a known interaction between Dash Diet and Tigecycline. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Are Dash Diet and Tigecycline used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Dash Diet in each. That is a conversation for your prescriber, especially if Tigecycline is being adjusted to a target.
Does Tigecycline interact with any supplements?
Yes. Tigecycline has documented interactions with 98 supplements in our database — Dash Diet is not one of them. The Tigecycline interaction page linked on this page lists every one, ranked by severity.
