Dyrenium (Triamterene) Medicare Coverage

Dyrenium is a medication that contains the active ingredient Triamterene. Dyrenium is used to treat edema (swelling) associated with congestive heart failure (CHF), cirrhosis of the liver, steroid use or unidentified causes.

Dyrenium works by preventing your body from reabsorbing sodium. This helps your body get rid of fluid. It is typically taken twice daily.

Common side effects of Dyrenium include dizziness, diarrhea, headache, upset stomach, fatigue and dry mouth.

Does Medicare cover Dyrenium or Triamterene?

While some Medicare plans may not cover Dyrenium, some Medicare Advantage plans and Medicare Part D plans may cover other diuretics.

• Medicare Advantage plans that offer prescription drug coverage are called Medicare Advantage Prescription Drug Plans (MA-PD). Most Medicare Advantage beneficiaries (88 percent) are enrolled in MA-PDs.¹
  
  
• Medicare prescription drugs plans each have their own formulary, or drug list, that details what prescription drugs are covered by the plan and how they are covered.

Drug coverage may vary based on plan availability.

Additional information

Unless your doctor instructs you otherwise, take your doses of Dyrenium after meals.

If you take it once daily, take it in the morning. Dyrenium will likely cause you to pass urine more often. Try to take it several hours before bedtime in order to avoid problems sleeping.

Dyrenium can increase the level of potassium that is in your blood. This can cause serious problems if it is not treated. The risk of elevated potassium levels is highest in people with diabetes, kidney problems, severe illnesses and those who are older.

Dyrenium can lead to kidney and liver problems when used for long periods of time. Symptoms of these problems can include problems or changes in urination, fatigue, upset stomach or yellow skin and eyes.

Because your body is getting rid of more water while taking Dyrenium, you could experience problems with your electrolytes.

Watch for signs of mood changes, confusion, abnormal heartbeat, dizziness, seizures, fatigue or the inability to pass urine. Talk to the doctor right away if you experience any of these side effects.
