What to Do If You Miss a Farxiga Dose

Take the missed dose as soon as you remember on the same day. Skip it if it's almost time for your next dose or it's already past that day's dosing time—do not double up to make up for it. Farxiga (dapagliflozin) is taken once daily, so staying on schedule prevents blood sugar spikes or other risks in type 2 diabetes management.[1]

Why Skipping Matters for Diabetes Control

Missing doses can raise blood glucose levels quickly, as Farxiga works by blocking kidney glucose reabsorption to excrete excess sugar in urine. Consistent use lowers A1C by about 0.5-1% over time; one missed dose might not derail long-term control but repeated skips increase complication risks like hyperglycemia.[1][2]

Does It Affect Heart or Kidney Benefits?

Farxiga also reduces heart failure hospitalization risk and slows kidney disease progression in approved uses. A single miss likely has minimal impact, but irregular dosing weakens these protections—studies show adherence above 80% is key for cardiovascular outcomes.[2][3]

Common Patient Questions on Missed Doses

• Can I take two doses the next day? No, doubling risks dehydration, low blood pressure, or genital infections from excess glucose excretion.
  
• What if I miss multiple days? Contact your doctor; they may adjust your regimen or check blood sugar.
  
• Does it interact with food or travel? No food effect, but pack extras for trips and set reminders.[1]
  
  

When to Call Your Doctor

Seek immediate care for symptoms like severe thirst, frequent urination, nausea, or confusion after missing doses, as these signal high blood sugar. Report any urinary tract infections or volume depletion signs promptly.[1][3]
