Dandelion may also decrease dehydroepiandrosterone, dehydroepiandrosterone-sulfate, androstenedione, and estrone-sulfate levels. Dandelion may increase the toxic effects when taken with supplements that lower blood pressure such as hawthorn ( Crataegus laevigata ). Toxic effects associated with herbs such as foxglove may increase when used in combination with dandelion. <a href="

[1]</a> Historically, dandelion is believed to possess diuretic (increased urination) properties and to lower blood potassium levels.

[1]</a> Dandelion may increase the effects and toxicity of blood pressure-lowering agents or niacin if taken together. Dandelion may also interact with cholesterol-lowering agents, such as bile acid sequestrants.<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-dandelion.html" TARGET="_blank"
[1]</a> There is a report with several patients that suggests that a combination herbal preparation containing dandelion improved chronic pain associated with colitis. Because multiple herbs were used, and this study was not well-designed or reported, the effects of dandelion are not clear.<a href="

[1]</a> If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy. Drug interactions with dandelion have rarely been identified, although there is limited study in this area.<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-dandelion.html" TARGET="_blank"
[1]</a> Consult with a qualified healthcare professional, including a pharmacist, to check for interactions.

http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-dandelion.html" TARGET="_blank"
[1]</a>
Dandelion may reduce the effects of the antibiotic ciprofloxacin (Cipro®) due to reduced absorption of the drug.<a href="

[1]</a> Parasitic infection due to ingestion of contaminated dandelion has been reported, affecting the liver and bile ducts, and characterized by fever, stomach upset, vomiting, loss of appetite, coughing, and liver damage.<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-dandelion.html" TARGET="_blank"
[1]</a> The effects or side effects of niacin or nicotinic acid may be increased (such as flushing and gastrointestinal upset), due to small amounts of nicotinic acid present in dandelion.<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-dandelion.html" TARGET="_blank"
[1]</a> Dandelion is generally regarded as safe with rare side effects including contact dermatitis, diarrhea, and gastrointestinal upset.<a href="

[1]</a> Doses of 1-2 teaspoons of a 1:5 root tincture in 45 percent alcohol have been used. There is not enough scientific research to recommend dandelion for use in children in amounts greater than those found in food.<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-dandelion.html" TARGET="_blank"
[1]</a> Dandelion cannot be recommended during pregnancy and breastfeeding in amounts greater than found in foods, due to a lack of scientific information.<a href="

[1]</a> In theory, dandelion may reduce the absorption of other drugs taken at the same time.<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-dandelion.html" TARGET="_blank"
[1]</a> Skin reactions have also been reported in dogs. Rhinoconjunctivitis and asthma have been reported after handling products, such as birdfeed, containing dandelion and other herbs with reported positive skin tests for dandelion hypersensitivity.<a href="
http://www.nlm.nih.gov/medlineplus/druginfo/natural/patient-dandelion.html" TARGET="_blank"

The levels of other herbs or supplements may become too high in the blood. In theory, dandelion may also alter the effects that other herbs or supplements possibly have on the P450 system, such as bloodroot, grapefruit juice, or St. John's wort. Dandelion leaves contain vitamin A, niacin, lutein, and beta-carotene and thus, supplemental doses of these agents may have additive effects or side effects.<a href="
