Exinef Tablets: Uses, Dosage, and Side Effects

Exinef tablets are a medication that is commonly prescribed for the treatment of various health conditions. This article provides an in-depth overview of Exinef tablets, including their uses, recommended dosage, and potential side effects.

Introduction to Exinef Tablets

Exinef tablets contain the active ingredient fludrocortisone acetate, which belongs to a class of drugs known as corticosteroids. Corticosteroids are synthetic hormones that closely resemble the natural hormone cortisol produced by the adrenal glands. Fludrocortisone acetate possesses potent mineralocorticoid properties.

Uses of Exinef Tablets

Exinef tablets are primarily used for conditions associated with salt and water retention in the body. Here are some of the common medical conditions where Exinef tablets may be prescribed:

  1. Primary Adrenal Insufficiency: Also known as Addison’s disease, this condition occurs when the adrenal glands do not produce enough cortisol and aldosterone. Exinef tablets help restore the balance of these hormones and manage the symptoms associated with adrenal insufficiency.
  2. Orthostatic Hypotension: This condition is characterized by a sudden drop in blood pressure upon standing, leading to dizziness, lightheadedness, and potentially fainting. Exinef tablets help increase blood pressure by promoting the retention of salt and water.
  3. Postural Tachycardia Syndrome (POTS): POTS is a disorder where an individual’s heart rate increases significantly upon standing up, causing symptoms like lightheadedness, rapid heartbeat, and fatigue. Exinef tablets may be prescribed to manage the symptoms of POTS by improving blood flow and regulating heart rate.
  4. Autonomic Dysfunction: Exinef tablets can be used in the treatment of various conditions associated with autonomic dysfunction, such as multiple system atrophy and pure autonomic failure. These conditions involve the dysfunction of the autonomic nervous system, which controls involuntary bodily functions.

Dosage and Administration

The dosage of Exinef tablets may vary depending on the specific medical condition being treated and individual patient factors. It is crucial to follow the directions provided by your healthcare provider or the instructions on the prescription label. Do not alter the dosage without consulting your doctor.

Exinef tablets are usually taken orally, with or without food. The tablets should be swallowed whole and not crushed or chewed. It is typically recommended to take Exinef tablets early in the morning to mimic the natural cortisol production cycle.

The usual starting dosage for adults is 0.1 to 0.2 mg per day, divided into two or three smaller doses. The dosage may be adjusted by your doctor based on your response to the treatment.

It is essential to monitor your blood pressure and electrolyte levels regularly while taking Exinef tablets to ensure the medication is working effectively and not causing any adverse effects.

Possible Side Effects

Like any medication, Exinef tablets may cause certain side effects in some individuals. Common side effects may include:

  • Headache
  • Dizziness
  • Insomnia
  • Fluid retention
  • Increased blood pressure

If any of these side effects persist or worsen, it is advised to seek medical attention. Additionally, inform your doctor if you experience any unusual or severe side effects while taking Exinef tablets.

It is important to note that Exinef tablets should only be used under the supervision of a healthcare professional, as prolonged use or abrupt discontinuation of the medication can lead to adrenal insufficiency.


Exinef tablets are a commonly prescribed medication for the management of various conditions related to salt and water retention. They can effectively alleviate symptoms associated with adrenal insufficiency, orthostatic hypotension, POTS, and autonomic dysfunction. However, it is crucial to follow the recommended dosage and consult your doctor regarding any potential side effects or concerns. By understanding the uses, dosage, and possible side effects of Exinef tablets, you can make informed decisions about your healthcare.
