Does minoxidil affect blood pressure?

Minoxidil works by opening up the blood vessels (vasodilation) which increases blood flow and thus, the amount of nutrients that get provided to the hair follicles.

Since it does cause dilation, it’s only logical to ask ourselves whether minoxidil affects blood pressure or not.

To answer briefly already, yes it can. Although it doesn’t always happen. Let me explain why minoxidil can potentially lower systolic pressure.




Does minoxidil affect your blood pressure?

Minoxidil can affect your blood pressure. But that’s not always a guarantee.

Minoxidil’s main mechanism of action is opening up the blood vessels (vasodilation) which increases blood flow and nutrients being delivered to the scalp, or other topical area where it’s used. This dilation in turn causes a lower blood pressure due to the blood flowing more freely.

Does topical minoxidil affect blood pressure?

Topical minoxidil can potentially cause lower blood pressure just the same as any kind of minoxidil can.

However, topical minoxidil typically doesn’t impact the blood pressure, or at most ever so slightly since there’s less systematic absorption of the product since it’s applied topically.

Systematic absorption means that the drug gets absorbed and circulated throughout the whole body.

Does minoxidil foam affect blood pressure?

Since minoxidil foam is a form of topical minoxidil, it will most likely not affect blood pressure. Nevertheless, it’s possible that the topical foam will slightly lower your systolic pressure.

Again, this is because there’s little systematic absorption involved when applying the foam topically.


What does minoxidil do to blood pressure?

Minoxidil typically lowers blood pressure due to the widening of the blood vessels.

How much the pressure level is lowered depends on:

  1. The dosage
  2. Applied topically or orally
  3. The physical response of the individual

Does minoxidil raise or lower blood pressure?

Minoxidil is more likely to lower blood pressure rather than raising it. That’s because minoxidil can cause vasodilation, which means opening up the blood vessels.

Does minoxidil lower blood pressure?

Minoxidil does have the potential to lower blood pressure, although most certainly not always.

Topical products such as minoxidil foam and solution are less likely to alter your blood pressure because there’s less systematic absorption involved.

Oral minoxidil in turn is more probable to cause a lower blood pressure since the product circulates throughout your entire body, causing more systematic absorption in the process.


Can minoxidil cause high blood pressure?

Can topical minoxidil cause high blood pressure?

No, minoxidil can not cause high blood pressure (hypertension).

As a matter of fact, using too much minoxidil, especially of the oral kind can cause hypotension.

Can I use minoxidil if I have high blood pressure?

I wouldn’t recommend using minoxidil if you have high blood pressure since it can interact with the medication you’re already taking to keep your hypertension in check.

This can cause hypotension which can make you experience dizziness, headaches, and in extreme cases, even fainting.

Can I use Rogaine if I have high blood pressure?

Since Rogaine is a brand of minoxidil, the same rules and guidelines apply to them as well.

You should not use Rogaine if you have high blood pressure since the product can correspond with the medication you’re using to combat your high blood pressure.

If this happens, then hypotension can be a potential consequence. Side effects of low blood pressure include, but are not limited to experiencing dizziness and headaches. Yet, those two are the most common issues.

Minoxidil does affect blood pressure by opening up the blood vessels, which lowers our systolic pressure. In some extremely rare instances, it can cause gynecomastia in men too.

This is more prevalent and likely when using oral minoxidil rather than topical minoxidil since there’s more systematic absorption involved with the oral kind.

I would not advise you to use minoxidil if you’re taking medication to combat your high blood pressure. Reason being that the minoxidil might interact with your blood pressure medication which can cause hypotension.
