Interactions

Yarrow may interact with the following medications:

Medications to reduce stomach acid -- Because yarrow may increase the production of stomach acid, it can interfere with both over-the-counter and prescription drugs including:

  • Cimetidine (Tagamet)
  • Famotidine (Pepcid)
  • Ranitidine (Zantac)
  • Esomeprazole (Nexium)
  • Omeprazole (Prilosec)
  • Lansoprazole (Prevacid)

Medications for high blood pressure -- Yarrow may lower blood pressure slightly, and could make the effects of any prescription drugs you take to lower blood pressure stronger.

Drugs that cause sleepiness -- Because yarrow is a mild sedative, it can increase the effects of other drugs you take for anxiety or sleepiness. These include:

  • Anticonvulsants such as phenytoin (Dilantin)
  • Barbiturates
  • Benzodiazepines such as alprazolam (Xanax) and diazepam (Valium)
  • Drugs for insomnia, such as zolpidem (Ambien), zaleplon (Sonata), eszopiclone (Lunesta), ramelteon (Rozerem)
