We found no known interaction between Sweet Violet and Cisplatin in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist.

Sweet Violet and Cisplatin

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 Cisplatin and Sweet Violet in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

Worth understanding: our licensed dataset holds no drug-interaction record for Sweet Violet at all — not against Cisplatin, 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.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. 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.

Sweet Violet safety at a glance

Sweet Violet overall Use caution Generally regarded as gentle in small culinary or tea amounts, but human safety data are limited.
Pregnancy Avoid Not enough safety information is available, so it is best avoided during pregnancy.
Breastfeeding Avoid There is not enough information to know if it is safe while breastfeeding, so avoid it.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

What Cisplatin’s Own FDA Label Lists

This is not an interaction — none of it involves Sweet Violet. These are the most notable effects listed in the ADVERSE REACTIONS section of Cisplatin’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 take both. 10 of them are worth acting on rather than waiting out — marked below.

  • An electrolyte imbalance Worth acting on
  • Loss of vision Worth acting on
  • Low magnesium Worth acting on
  • Hearing loss Worth acting on
  • A stroke or mini-stroke Worth acting on
  • Dehydration Worth acting on
  • Low sodium Worth acting on
  • A low white blood cell count Worth acting on mentioned in 12.2% of FDA reports for Cisplatin
  • Low potassium Worth acting on
  • A heart attack Worth acting on

Showing the 10 most notable of 33 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 Cisplatin. Read the label on DailyMed › Where a percentage is shown, it is the share of 77,669 voluntary FDA FAERS reports for Cisplatin that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Sweet Violet’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Sweet Violet side to compare — that is a limit of the record, not a statement that Sweet Violet has no side effects.

From our pharmacist’s overview on the Cisplatin page

“Kidney damage is the risk I would flag first for anyone receiving cisplatin (Platinol-AQ). Cisplatin is a chemotherapy drug that already stresses the kidneys, and two of the three major-rated interactions on this list, Siberian cocklebur and asarabacca, involve herbs that can injure the kidneys on their own, stacking harm on an organ t…”

About Sweet Violet

What is Sweet Violet?

  • Cough and sore throat
  • Bronchitis and chest congestion
  • Trouble sleeping
  • Skin irritation
  • Mild constipation
  • Headache

Sweet Violet is a traditional herb used mainly as a soothing remedy for coughs, sore throats, and minor respiratory complaints. Modern scientific evidence supporting these uses is very limited, so it should not replace proven treatments. It is generally considered gentle in food-like amounts, but talk with your pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or giving it to a child.

Viola odorata · Violaceae · Flowers, leaves, and roots; sometimes the whole plant · Tea (infusion), syrup, dried herb, tincture, and topical preparations

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

Sweet Violet: dosing

There is no standardized or officially established dose for Sweet Violet. Traditional use most often involves a tea made from the dried flowers or leaves, or a syrup for cough, but exact amounts vary widely between products and recipes.The safest approach is to follow the directions on the product label and not exceed the recommended amount.

About Cisplatin Injection

What Is Cisplatin Injection Used For?

Brand name: Platinol-AQ

Cisplatin Injection is used to treat three types of cancer. For metastatic testicular tumors and metastatic ovarian tumors, it is used as part of combination chemotherapy — alongside other approved cancer medicines — in patients who have already had surgery and/or radiation therapy. For metastatic ovarian tumors, it can also be used alone as a second-line treatment when standard chemotherapy has stopped working and cisplatin has not been tried before.

For advanced bladder cancer (specifically transitional cell bladder cancer) that can no longer be treated with surgery or radiation, Cisplatin Injection is used as a single agent.

Most-Reported Side Effects for Cisplatin

From FAERS, the FDA’s public side-effect reporting system (77,669 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Nausea 5,437 reports
Neutropenia 4,877 reports
Disease progression 4,657 reports
Febrile neutropenia 4,606 reports
Vomiting 4,566 reports
