What Is Finasteride and How Does It Work?

To get an idea of what Finasteride dose you should be taking, you need to understand what this drug is and how it works. Finasteride is a drug used to help prevent male hair loss and benign prostate hyperplasia (BPH).

The supplement belongs to a class of drugs known as 5-alpha reductase inhibitors. These supplements prevent testosterone from turning into a different hormone called DHT. 

When you have too much DHT in the body, it causes the prostate to grow bigger and prevents hair growth. Since Finasteride limits the creation of DHT, it also limits these phenomena from occurring.

How to Take Finasteride

There are two major ways to take Finasteride: 

  1. Orally
  2. Topically

Let’s take a look at what you need to know about each of these methods for taking Finasteride. 


To take Finasteride, you can take it either with food or without food. However, you do need a glass of water as you’ll swallow your tablets with the liquid.

You don’t need to take it at any particular time of day. However, you should try to take your Finasteride at the same time each day.

When taking oral Finasteride, make sure not to crush the pills. Swallow them whole without chewing them. 


If you’re going to take Finasteride topically, you’ll need to start by getting your topical Finasteride dosage right. The proper dosage is just 1mL of the solution twice a day, with eight hours between doses. 

To apply the drug, use a medicine dropper to apply the solution to the affected part of your head. There is no need to rub the solution into your head. 

To apply Finasteride, apply the exact dosage your healthcare provider has instructed specifically for you.

What Finasteride Dose Should You Use?

Your Finasteride dosage will depend on whether you’re using it for hair loss or for an enlarged prostate. These two issues require different doses to ensure you don’t harm yourself. 

For BPH, you’ll want to take Finasteride 5mg. The stronger dose helps prevent your prostate from growing extremely quickly. 

On the other hand, if you’re taking Finasteride for hair loss, you’ll need a lower dose. In this situation, you can usually take Finasteride 1 mg tablets. 

What If You Missed a Dose of Finasteride?

If you miss a dose of Finasteride, don’t panic. If you miss one or even two doses of the drug, you won’t find any serious effect on your body, and the missed dose won’t do you any harm.

However, if you miss more Finasteride than that, you may notice that some sudden changes take place. This can also happen if you forget to take your dosage at the right time. 

In most cases, if you miss a dose of Finasteride, all you need to do is take the dose as soon as you remember. This is usually enough to get you back on track. 

Remember, you should always speak to a healthcare professional about missed doses. They’ll be able to give you advice about your unique situation.
