Medication Overview

Avodart (generic name: dutasteride) is a prescription medication primarily used to treat benign prostatic hyperplasia (BPH), commonly known as an enlarged prostate. It belongs to a class of drugs known as 5-alpha-reductase inhibitors.

Dosage Forms

Avodart is available in capsule form. Each capsule contains 0.5 mg of dutasteride. The capsules are soft gelatin and are designed for oral administration.

Mechanism of Action

Avodart works by inhibiting the conversion of testosterone to dihydrotestosterone (DHT), a hormone involved in prostate growth. This reduction in DHT levels helps to shrink the enlarged prostate gland, thereby alleviating associated symptoms.

Intended Use

Avodart is indicated for the treatment of symptomatic benign prostatic hyperplasia (BPH) in men with an enlarged prostate. It is often prescribed to improve urinary flow and to reduce the risk of acute urinary retention and the need for BPH-related surgery.

Administration Guidelines

Take Avodart exactly as prescribed by your healthcare provider. Swallow the capsule whole; do not chew, crush, or split it. It can be taken with or without food. Consistent daily intake at the same time each day is recommended.

Contraindications

Avodart is contraindicated in patients with a known hypersensitivity to dutasteride, other 5-alpha-reductase inhibitors, or any component of the medication. It should not be used by women, particularly during pregnancy, due to potential teratogenic effects.

Potential Side Effects

Common side effects include impotence, decreased libido, ejaculation disorders, and breast tenderness or enlargement. Less common effects may include allergic reactions such as rash, itching, swelling, and difficulty breathing.

Drug Interactions

Avodart may interact with other medications such as alpha-blockers, anticholinergics, and PDE5 inhibitors. Caution is advised when combining it with other drugs metabolized by the CYP3A4 enzyme system.

Monitoring Parameters

Regularly monitor prostate-specific antigen (PSA) levels during treatment with Avodart. A decrease in PSA levels is expected and can be used to assess adherence and treatment response. Continual assessment of liver function tests is also recommended.

Overdose Management

There is no specific antidote for Avodart overdose. In the event of an overdose, provide symptomatic and supportive treatment. Contact a healthcare provider immediately if an overdose is suspected.

Storage Conditions

Store Avodart capsules at room temperature, away from moisture and heat. Keep the medication in its original container and out of reach of children. Avoid storing in the bathroom or any area prone to moisture.

Special Populations

Use caution when prescribing Avodart to patients with hepatic impairment. There is limited data on the use of Avodart in older adults with severely impaired liver function, necessitating close monitoring for adverse effects.

Pregnancy and Lactation

Avodart is contraindicated in women who are pregnant or may become pregnant. Exposure to dutasteride during pregnancy can lead to adverse developmental effects on a male fetus. It is not intended for use by women or children.

Patient Counseling Information

Inform patients about the potential side effects and the importance of adherence to the prescribed regimen. Emphasize that symptom relief may take several months and the necessity of regular follow-up appointments. Remind patients to read the accompanying medication guide thoroughly.

Handling Instructions

If a capsule is broken or leaking, avoid contact with the skin. Wash the affected area immediately with soap and water if accidental contact occurs. Women who are pregnant or who may become pregnant should avoid handling the medication.

Laboratory Test Interferences

Alert patients that Avodart may interfere with the results of a PSA test. Prior to having lab tests, patients should inform the laboratory personnel and healthcare provider about taking Avodart.

Summary of Benefits

Avodart offers significant improvement in urinary flow and reduction in symptoms of BPH. It also decreases the risk of acute urinary retention and the necessity for surgical intervention.
