Common use

Proscar (finasteride 5mg) is a prescription prostate medication used to treat benign prostatic hyperplasia (BPH), a condition commonly known as enlarged prostate. As a 5-alpha reductase inhibitor, finasteride works by blocking the conversion of testosterone into dihydrotestosterone (DHT) — the hormone primarily responsible for prostate growth. By lowering DHT levels, Proscar gradually reduces the size of the enlarged prostate, helping to restore normal urinary function. When you buy Proscar online, you receive a clinically proven BPH treatment that helps control urinary symptoms, diminishes urinary retention, improves urine flow, and significantly reduces the risk of needing surgical intervention. Finasteride has been extensively studied in large-scale clinical trials and remains one of the most widely prescribed medications for long-term prostate health management.



Dosage and direction

Take Proscar by mouth with a full glass of water, with or without food. The standard recommended dose for BPH treatment is one 5mg tablet taken once daily. Avoid cutting, crushing, or chewing this medicine, as the tablet has a protective coating that prevents contact with the active ingredient. Proscar should be taken at the same time each day to maintain consistent drug levels in your body. Improvement in symptoms may take six months or longer, so it is important to continue taking finasteride even if you do not notice immediate results. Consult your doctor concerning the proper dose and duration of therapy for your individual condition. Do not adjust your dose without medical guidance.



Precautions

Before taking Proscar, tell your doctor or pharmacist if you are allergic to finasteride or dutasteride, or if you have any other known allergies. Inform your healthcare provider about your complete medical history, especially if you have liver disease, urinary tract obstruction, or prostate cancer. Since finasteride can be absorbed through the skin, women who are pregnant or may become pregnant must not handle crushed or broken Proscar tablets, as exposure to the active ingredient may cause birth defects in a developing male fetus. Men taking this prostate medication should be aware that finasteride may affect prostate-specific antigen (PSA) test results, which are used for prostate cancer screening. Discuss this with your doctor before undergoing any PSA testing. If you buy finasteride for BPH treatment, ensure regular follow-up appointments with your physician to monitor your progress and prostate health.



Contraindications

Proscar is contraindicated in women and children. This medication should not be used by patients who have demonstrated a reaction of hypersensitivity to finasteride or any of its inactive ingredients. Women of childbearing age must avoid contact with crushed or broken tablets due to the risk of fetal harm. Proscar generic and brand-name versions carry the same contraindications. Patients with known liver dysfunction should use this 5-alpha reductase inhibitor with caution, as finasteride is metabolized primarily in the liver. Always inform your healthcare provider of all medical conditions before starting treatment for benign prostatic hyperplasia.



Possible side effect

The most common side effects associated with Proscar include decreased libido, reduced volume of ejaculate, erectile dysfunction, dizziness, unusual weakness, drowsiness, trouble sleeping, blurred vision, and runny nose. These side effects of finasteride are generally mild and may diminish over time as your body adjusts to the medication. Some men may experience breast tenderness or enlargement, skin rash, or swelling of the lips and face.

Stop using Proscar and seek immediate medical attention if you experience any of these serious side effects: a painful penile erection lasting 4 hours or longer, severe dizziness or fainting, signs of an allergic reaction such as difficulty breathing, hives, or swelling of the throat. Although serious allergic reactions to this enlarged prostate treatment are rare, they require urgent medical care.

If you notice any effects not listed here, contact your doctor or pharmacist promptly. Report any changes in breast tissue, including lumps, pain, or nipple discharge, to your healthcare provider without delay.



Drug interaction

No drug interactions of major clinical importance have been identified with Proscar. Finasteride is metabolized by the liver through the cytochrome P450 3A4 enzyme system, but it does not significantly affect the metabolism of other drugs processed through this pathway. However, to ensure safe use of this BPH treatment, tell your doctor or pharmacist about all prescription medications, over-the-counter drugs, and herbal products you are currently using before starting finasteride therapy. This includes vitamins, supplements, and any other prostate health products you may be taking.



Missed dose

If you have missed your dose of Proscar, take it as soon as you remember. If it is nearly time for your next scheduled dose, skip the missed dose and resume your usual dosing schedule. Do not take a double dose to make up for the one you missed. Maintaining a consistent daily routine will help you remember to take your finasteride tablet at the same time each day. Missing occasional doses is unlikely to significantly affect your BPH treatment, but regular daily use provides the best results for managing enlarged prostate symptoms.



Overdose

If you suspect you have taken too much Proscar, seek emergency medical attention right away. Contact your local poison control center or go to the nearest emergency room. The symptoms of finasteride overdose may include chest pain, nausea, irregular heartbeat, and feeling light-headed or fainting. In clinical studies, single doses of finasteride up to 400mg did not produce significant adverse effects, but medical evaluation is still recommended after any suspected overdose of this prostate medication.



Storage

Store Proscar at room temperature between 68-77 degrees F (20-25 degrees C) in a dry place away from direct light and moisture. Do not store this medication in the bathroom or near a kitchen sink where it may be exposed to humidity. Keep the tablets in their original container with the cap tightly closed. Keep all medications, including finasteride, out of reach of children and pets. Do not use Proscar past its expiration date. Dispose of expired or unused prostate medication properly — consult your pharmacist about safe disposal methods.
