For best results:

One box contains a complete 10-day course.
Can I take DIVIRNAM® every day?
No.
DIVIRNAM® is not intended as a daily supplement. It is designed to be used during periods of illness, exposure, or before anticipated exposure to support your immune system.
Should I continue taking my Vitamin D supplement?
No.
DIVIRNAM® already provides 4,000 IU of Vitamin D3 daily when taken as directed (1 tablet every 12 hours).
If you currently take a Vitamin D supplement, pause it while taking DIVIRNAM®. Once you complete the 10-day course, you may resume your normal Vitamin D supplementation unless otherwise directed by your healthcare provider.
Are there any known drug interactions with DIVIRNAM®?
DIVIRNAM® contains ammonium chloride, which may interact with certain medications because it can change the acidity (pH) of the urine. This may affect how some medications are processed and eliminated by the body.
If you take prescription medications, especially those affecting kidney function, electrolyte balance, or urine pH, consult your healthcare provider or pharmacist before taking DIVIRNAM®.
