Buy Minoxidil 2.5mg Tablets Online
You can buy oral minoxidil tablets online from our UK registered online pharmacy and Doctor service. Oral minoxidil tablets are an effective treatment for male pattern baldness in men.
After completing an online assessment form, our GPs can assess if the treatment is suitable for you. If approved, a prescription will be issued to our pharmacy team, who will dispense and dispatch your order.
Oral Minoxidil Overview
Oral Minoxidil is a medication licensed to treat high blood pressure, which can also be prescribed off-label for the treatment of hair loss. Recognized for its efficacy, oral Minoxidil has been a cornerstone in the fight against hair loss. Our UK registered online pharmacy provides access to oral Minoxidil after a thorough online assessment, ensuring the treatment is suitable for you.
We have both branded Loniten and generic minoxidil; these medications are almost identical, using the same active ingredient, and are just as effective as each other. The only differences are a few minor ingredients, and the price.
Our doctors prescribe oral minoxidil for hair loss as 'off-label' use. 'Off-label' means the medicine is being used in a way that is different to how it's described in the medical licence of the product. You can read more information here.

How Does Oral Minoxidil Work?
Oral minoxidil was originally developed as a medication for high blood pressure but was found to have the beneficial side effect of promoting hair growth. It works by dilating small blood vessels, improving blood flow to hair follicles, which can rejuvenate and stimulate hair growth, offering hope for those with hair loss. Androgenetic alopecia (hair loss) is often caused by a hormone called DHT. This hormone is derived from testosterone, and reduces blood flow to the hair follicles. While other hair loss treatments, such as finasteride, may help to lower your levels of DHT, minoxidil instead focuses on reverting some of the damage DHT causes.
When you start taking minoxidil, you may notice some extra hair shedding. This is a normal part of the hair growth cycle, and shows that the medication is working. The hair that grows in its place will be stronger and thicker than the lost hairs.
Oral Minoxidil vs Topical Minoxidil
While both oral and topical minoxidil treatments use the same active ingredient, there can be some differences between them.
The most obvious is how they are taken; topical minoxidil is applied directly to the scalp. While this may give slightly more control over which areas receive the treatment, it can be difficult to use, and to fit into your daily routine.
Oral Minoxidil users may find the systemic approach more convenient or effective compared to topical treatments, which require direct application to the scalp. While oral Minoxidil can offer widespread benefits for hair growth, it may also carry a greater risk of systemic side effects. It's essential to consult with a healthcare professional to determine the most appropriate form of Minoxidil for your situation.
We would recommend that a topical preparation is tried first before considering oral tablets.
Oral Minoxidil Alternatives
Some patients may find that oral minoxidil isn't as effective at treating their hair loss. While we do stock alternatives for male pattern baldness, please note these may not be suitable for female pattern baldness.
- Regaine For Men For Hair Loss (topical minoxidil)
- Propecia
- Finasteride
Oral Minoxidil Dosage
The minoxidil dose is typically lower to treat androgenetic alopecia compared to its licensed indication of hypertension - the starting dose is 1.25mg (half a tablet) for two weeks, increasing to 2.5mg after that.
This means that patients will need to halve the tablet themselves to start with. We would suggest a tablet cutter.
It is best practice to take your dose of minoxidil at the same time each day.
Minoxidil is a long-term medication; it may take a few weeks to months to see results. Should you stop taking minoxidil, hair regrowth will stop.

How does it work for hair loss?

Skip the missed dose and do not double up, as overdose risks include heart complications.
Effectiveness & Results
Is oral minoxidil better than topical?
