Some pharmaceutical drugs react with the herb dandelion. Please use caution when using the herb if you are prescribed the following medications:
Dandelion might decrease how much antibiotic the body absorbs. Taking dandelion along with antibiotics might decrease the effectiveness of some antibiotics.
Examples of drugs that might interact with dandelion include ciprofloxacin (Cipro), enoxacin (Penetrex), norfloxacin (Chibroxin, Noroxin), sparfloxacin (Zagam), trovafloxacin (Trovan), and grepafloxacin (Raxar).
Dandelion might have an effect like a water pill or "diuretic." Taking dandelion might decrease how well the body gets rid of lithium. This could increase how much lithium is in the body and result in serious side effects. Talk with your healthcare provider before using this product if you are taking lithium. Your lithium dose might need to be changed.
Some medications that are changed by the liver include amitriptyline (Elavil), haloperidol (Haldol), ondansetron (Zofran), propranolol (Inderal), theophylline (Theo-Dur, others), verapamil (Calan, Isoptin, others), and others.
The body breaks down some medications to get rid of them. The liver helps break down these medications and dandelion might increase how quickly some medications are changed by the liver, decreasing how well the medication works in the body.
Some "water pills" that increase potassium in the body include amiloride (Midamor), spironolactone (Aldactone), and triamterene (Dyrenium).
