General preparation

  • Bring your referral, Medicare card, and any previous imaging if available.
  • Arrive 10–15 minutes before your appointment to complete forms.
  • Wear loose, comfortable clothing without metal zips, belts, or buttons.
  • Leave jewellery, watches, and piercings at home when possible.
  • Continue taking your usual medications unless instructed otherwise.

Fasting and hydration

  • If your scan uses contrast, avoid eating for 2–4 hours before your appointment.
  • Drink water to stay hydrated; clear fluids are usually fine.
  • If your scan does not use contrast, you can generally eat and drink normally.

Patients with diabetes or kidney conditions

  • Tell us if you have diabetes or kidney problems. These conditions can affect how your body handles contrast dye.
  • If you take metformin, you may need to pause it temporarily after your scan. We will give specific instructions.
  • Bring a list of current medications with you.

Contrast injection preparation

  • For contrast scans, a small IV cannula will be placed in your arm.
  • Let staff know if you have had any reaction to iodine contrast before.
  • Inform us of asthma, allergies, thyroid disease, or if you are pregnant or breastfeeding.

Pregnancy and children

  • If you are or might be pregnant, inform us before your scan. We will assess whether CT is necessary or suggest an alternative such as ultrasound or MRI.
  • For children, we tailor scanning protocols to keep radiation dose as low as possible.

On the day of your scan

  1. Arrive a few minutes early to complete your questionnaire.
  2. Remove metal items and change into a gown if required.
  3. If contrast is used, you will have a brief consultation before the injection.
  4. Relax and follow the radiographer’s instructions during the scan.

  • You can eat, drink, and resume normal activities immediately unless told otherwise.
  • If you notice redness, swelling, or pain at the injection site, contact us or your GP.

Quick checklist

  • Referral and Medicare card ready
  • Loose, metal-free clothing

Betnovate in Australia: A Doctor’s Review for Adults Over 30 Who Want Real Relief from Eczema, Psoriasis and Dermatitis

Written from a clinical perspective by a doctor experienced in Australian dermatology.

Attention: Does Your Skin Make You Feel Older, Embarrassed or Constantly Uncomfortable?

If you are over 30, you may have spent years battling itchy, red, flaking skin. You have probably tried many things that promised relief but failed to deliver. Maybe you recognise these situations:

  • Over-the-counter moisturisers that feel greasy but stop working within an hour.
  • Natural remedies, oatmeal baths or essential oils that leave your skin feeling worse.
  • Hiding your scalp under hats because of visible flakes on your collar or shoulders.
  • Avoiding dark clothing, handshakes or the gym because of cracked, weeping patches on your hands or elbows.
  • Waking up at night scratching, then feeling exhausted and self-conscious the next day.

You are not alone. Eczema, dermatitis and psoriasis affect millions of Australian adults. The real problem is often not lack of effort—it is lack of the right medicine. Betnovate is one of Australia’s most trusted prescription corticosteroid treatments for exactly these conditions. Used correctly, it can break the itch-scratch cycle and give you your skin back.

Interest: What Is Betnovate and Why Do Australian Doctors Prescribe It?

Betnovate contains betamethasone valerate 0.1%, a potent topical corticosteroid that rapidly reduces inflammation, redness, swelling and itch. It works by calming the immune cells in the skin that drive eczema, dermatitis and psoriasis flares. In Australia, Betnovate is a Schedule 4 prescription-only medicine, which means your doctor must assess your skin and prescribe the right form and duration.

Betnovate manufacturer: GlaxoSmithKline Australia Pty Ltd (GSK), one of the world’s most respected pharmaceutical companies with decades of safety data and quality control. When you use Betnovate, you are using a medicine with a long clinical history and trusted manufacturing standards.

Betnovate comes in several forms, so your doctor can match the vehicle to your skin type and body area:

Betnovate Form Best For Key Advantage
Cream Weeping, moist eczema; body folds Light, easily absorbed, cooling
Ointment Dry, thickened psoriasis plaques; cracked heels or hands More hydrating, stronger barrier
Lotion Hairy areas; larger body areas Spreadable, less greasy
Scalp Application Scalp psoriasis, seborrhoeic dermatitis, itchy scalp Liquid base that reaches the scalp without matting hair

Understanding Your Dose: The Betnovate Finger Tip Unit

One of the biggest mistakes adults make is under-dosing or over-dosing topical steroids. The Betnovate finger tip unit (FTU) solves this. One FTU is the amount of cream or ointment squeezed from the tube along the adult index finger from the tip to the first crease. This equals about 0.5 g and covers roughly two adult palms.

Area Adult FTU Needed Notes
One hand (front and back) 1 FTU Apply thinly in direction of hair growth
One arm 3 FTU Use enough to cover the red area, not just a dot
One leg 6 FTU Ointment may need slightly more massage
Whole scalp About 3–4 drops of scalp application per section See scalp instructions below

Using the correct FTU helps you apply enough medicine to clear the rash quickly, but not so much that you increase the risk of side effects.

Desire: How Betnovate Can Give You Your Confidence Back

Betnovate for Psoriasis

Psoriasis is not just dry skin. It is an overactive immune response that causes thick, silver-scaled plaques that can crack, bleed and ache. Betnovate is a first-line short-term treatment for mild to moderate plaque psoriasis, especially on the elbows, knees and scalp. It calms the inflammatory cells, lifts scaling and stops the itch. Many patients notice a visible difference within a few days of starting. Imagine wearing dark clothing again without worrying about flakes, or going to the gym without hiding your elbows.

Betnovate Scalp Application: How to Use It Correctly

If you have an itchy, flaking scalp, Betnovate Scalp Application is one of the most effective options. The alcohol-based liquid penetrates the hair and reaches the skin without leaving your hair greasy. Here is the correct method:

Step Instruction
1 Part the hair into small sections to expose the red, scaly areas.
2 Apply a few drops of Betnovate Scalp Application directly onto the affected area.
3 Massage gently with your fingertips—do not scratch with nails.
4 Wash your hands afterwards.
5 Use once or twice daily as prescribed, usually for 2–4 weeks only.

Because the liquid is light and non-greasy, it won’t ruin your hairstyle or leave you looking like you dipped your head in oil. You can use it in the morning and still go to work with confidence.

Betnovate vs Elocon: Which One Should You Choose?

Many Australian patients ask about Elocon (mometasone furoate). Both are potent topical corticosteroids, but there are important differences your doctor may consider.

Feature Betnovate Elocon
Active ingredient Betamethasone valerate 0.1% Mometasone furoate 0.1%
Availability in Australia PBS listed for certain indications; widely available PBS listed; widely available
Frequency Usually 1–2 times daily Usually once daily
Vehicle options Cream, ointment, lotion, scalp application Cream, ointment, lotion
Cost Often more affordable Can be more expensive depending on pack
Best for scalp Excellent—dedicated scalp application Lotion can be used but less tailored

Elocon has the advantage of once-daily dosing and may have a slightly better safety profile for skin thinning in some areas. However, Betnovate remains a go-to for many Australian doctors because of its range of vehicles, rapid action, trusted manufacturer and affordability. If your main problem is the scalp, Betnovate Scalp Application is often the more practical choice.

Betnovate Side Effects and Adrenal Suppression: The Facts You Need

No doctor should pretend Betnovate is risk-free. But when used correctly, the risks are low and manageable. Most side effects occur with prolonged use on sensitive areas, under plastic wrap, or on large body areas for many weeks.

Side Effect Who Is Most at Risk How to Reduce Risk
Skin thinning (atrophy) Long-term use on face, armpits, groin Avoid face/folds unless directed; use short courses
Stretch marks (striae) Younger skin, high-dose areas Do not exceed prescribed amount
Perioral dermatitis / acne Use on face Usually avoid Betnovate on face; use a milder steroid
Burning or irritation Sensitive or broken skin Apply to intact skin; stop and see your doctor if severe
Temporary lightening of skin Darker skin tones, prolonged use Use a thin layer; stop after the flare clears

Betnovate adrenal suppression is a rare but serious risk if large amounts are used on large body areas, under occlusion (plastic wrap), or for many weeks continuously. Your adrenal glands can slow their own cortisol production. Symptoms may include unexplained tiredness, dizziness, nausea, weight loss and low blood pressure. That is why Betnovate is prescription-only and why your doctor will advise a maximum duration—often 2–4 weeks for a flare, then a break or taper. For most adults treating a localised patch of eczema or scalp psoriasis, adrenal suppression is extremely unlikely.

Betnovate Environmental Impact

As a doctor, I also think about what happens after you use a medicine. Topical corticosteroids like Betnovate can enter waterways if washed down the drain in large amounts. You can reduce the environmental impact by:

  • Applying only the fingertip unit amount needed—no excess.
  • Wiping any leftover cream into a tissue and placing it in the bin, not rinsing it down the sink.
  • Disposing of empty tubes and packaging responsibly through council recycling programmes where possible.
  • Never flushing leftover medicine down the toilet.

This small step protects Australian waterways while you protect your skin.

Action: Take Control of Your Skin Today

You have spent enough years scratching, hiding and apologising for your skin. Betnovate is not a cosmetic; it is an effective, prescription-strength medicine that can clear a flare and let you get back to work, sleep and social life—without the constant itch.

Here is what to do now:

  • Book a telehealth or in-person appointment with your Australian GP. Mention your exact symptoms: itch, scaling, location, how long it has lasted.
  • Ask your doctor if Betnovate cream, ointment or scalp application is right for you. Discuss the fingertip unit and duration.
  • Get your prescription filled at a local pharmacy. You can buy Betnovate from any Australian pharmacy once you have a valid prescription.
  • Use it exactly as directed. Clear the flare, then follow your doctor’s advice on tapering or stopping.

Your skin is the largest organ you have—and you deserve to feel comfortable in it. With Betnovate, used responsibly under medical supervision, you can finally get the relief you have been searching for.
