Dyrenium

Dyrenium treats fluid retention. Avoid salt substitutes containing potassium. Take Dyrenium after meals.

Dyrenium Overview

Updated: 

Dyrenium is a prescription medication used to treat fluid retention caused by congestive heart failure and other conditions. Dyrenium belongs to a group of drugs called diuretics ("water pills"). Specifically, it is a "potassium-sparing" diuretic which means that it works by helping the body get rid of excess fluid by increasing the amount of salt and water the kidneys remove from the blood, while still keeping potassium in the body.

Dyrenium comes in capsule form and is taken twice daily, after meals.

Common side effects of Dyrenium include vomiting and headache.

This medication can cause dizziness. Do not drive or operate heavy machinery until you know how it affects you.

Dyrenium and Pregnancy

Dyrenium falls into category C. This medication may be given to a pregnant woman if her healthcare provider believes that its benefits to the pregnant woman outweigh any possible risks to her unborn baby.

It is not known if Dyrenium will harm your unborn baby.

Dyrenium and Lactation

Dyrenium FDA Warning

Warnings

Abnormal elevation of serum potassium levels (greater than or equal to 5.5 mEq/liter) can occur with all potassium-sparing agents, including Dyrenium. Hyperkalemia is more likely to occur in patients with renal impairment and diabetes (even without evidence of renal impairment), and in the elderly or severely ill. Since uncorrected hyperkalemia may be fatal, serum potassium levels must be monitored at frequent intervals especially in patients receiving Dyrenium, when dosages are changed or with any illness that may influence renal function.
