High-priority interactions for Lunesta

Working with the pharmacist
A pharmacist review of all current medications is the practical safeguard against unintended interactions with Lunesta.

Frequently asked questions
What's the most important Lunesta interaction to know? ▾
For most Sleep Aids and Hypnotics medications, the highest-priority interaction is with nitrate medications used for chest pain — this combination is often a hard contraindication. After that, strong CYP3A4 inhibitors (some antifungals, macrolides) are the next concern at routine 1mg, 2mg, 3mg doses.
Do I need to tell the pharmacist about supplements? ▾
Yes. Supplements and herbal products can interact with Lunesta in ways that prescription drug-drug interaction databases miss. The pharmacist needs the complete picture — including supplements like St John's Wort, grapefruit-containing products and high-dose vitamins — to flag risks at 1mg, 2mg, 3mg.
