Your copay and deductible costs for any prescription drug can vary depending on what coverage stage you’re in and the Medicare drug plan you have.
|Deductible stage||Typical copay stage|
|Your deductible is the amount of money you must spend on covered drugs before your Medicare drug coverage starts paying its share of costs.
In the deductible stage, you’re responsible for the full cost of your prescription drugs.
Some Medicare prescription drug plans have a $0 deductible. Medicare drug plans cannot have a deductible more than $415 in 2019.
|After you meet your Part D deductible, you enter the initial coverage period.
During this phase (the typical copay stage), you pay a copayment (flat fee) or coinsurance (percentage) for your covered medications.
Metolazone will make you urinate more frequently to get rid of the extra fluid that is causing swelling. Metolazone should be taken a few hours before you go to bed, to avoid night time bathroom trips that disrupt sleep.
If you are taking Metolazone, you may be at a higher risk of electrolyte problems due to fluid loss. Signs of electrolyte problems can include confusion, muscle problems, abnormal heartbeat, extreme thirst, fatigue, dry mouth and upset stomach.
Kidney problems may also arise from an excess loss of fluid. Kidney problems can include the inability to pass urine, blood in the urine or a noticeable weight gain.
If you are diabetic, Metolazone may increase your blood sugar. Liver and pancreas problems have also rarely been reported by people taking Metolazone.
