Armotraz is a prescription-only medicine containing Anastrozole 1mg. It belongs to a medicine class called aromatase inhibitors Hormone receptor-positive breast cancer in postmenopausal women is the primary condition for which this medicine is prescribed. By reducing oestrogen levels in the body, it deprives cancer cells of the stimulus they rely on to grow and multiply.
If you have been prescribed Armotraz in the UK, you may have questions about what it does. Anastrozole is the active ingredient in Armotraz. It is a medicine used in breast cancer treatment. Your doctor may refer to it by different brand names, including Arimidex.
Armotraz is prescribed as part of a planned cancer treatment programme. It is a prescription-only medicine (POM) available through regulated UK pharmacies. A clearer understanding of the treatment journey is gained when patients are informed about how Armotraz works.
Many postmenopausal women in the UK are prescribed Anastrozole after surgery or other cancer treatments. What Armotraz is, how it functions, and what the treatment involves are all covered in this guide.
What Is Armotraz?
Used in the management of breast cancer, Armotraz is classified as an anticancer medicine. Anastrozole 1mg serves as its active pharmaceutical ingredient. Aromatase inhibitors are the class of medicines to which Armotraz belongs.
Armotraz is prescribed exclusively for women who are postmenopausal, meaning those whose menstrual periods have stopped. Medicine uses to treat hormone receptor-positive breast cancer. This type of cancer uses oestrogen to grow and spread.

Armotraz is not available over-the-counter. A qualified UK healthcare professional is required to prescribe this medicine. Dosage instructions given by your doctor must be followed with care at all times.
How Anastrozole Works in the Body
The enzyme aromatase is blocked by Anastrozole. This inhibition is central to how the medicine works. In the body’s fatty tissue, androgens are converted into oestrogen by this enzyme. By blocking aromatase, Armotraz significantly reduces oestrogen levels.
Oestrogen acts as a growth signal for certain types of breast cancer. When a cancer’s growth is driven by oestrogen in this manner, it is classified as a hormone receptor-positive cancer. A fall in oestrogen levels removes the essential growth stimulus that these cancer cells depend upon.
Armotraz is selective in how it works. It targets the aromatase enzyme specifically, without disrupting other hormonal processes. This selectivity helps reduce unnecessary side effects compared to broader hormone therapies.
When Doctors Prescribe Armotraz
Doctors prescribe Armotraz in several clinical situations related to breast cancer treatment. It is most commonly used after surgery or other primary treatments. It helps prevent cancer from returning in the early stages.
Where breast cancer has advanced or spread to other parts of the body, Armotraz may be included as part of the overall treatment plan. Because oestrogen is suppressed, disease progression is slowed in this clinical context. It is only suitable for postmenopausal women whose periods have stopped naturally or through treatment.
- After surgery, Armotraz is commonly prescribed for early-stage hormone receptor-positive breast cancer
- Reducing the risk of breast cancer returning is another key reason Armotraz is used in postmenopausal women
- Advanced or metastatic breast cancer that responds to oestrogen
- Adjuvant therapy following chemotherapy or radiotherapy
Your doctor will assess your hormone receptor status before prescribing. Aromatase inhibitor therapy is not effective for every type of breast cancer. A specialist oncologist will determine whether Armotraz is appropriate for your case.
Benefits of Armotraz
Armotraz offers significant clinical benefits for eligible patients. After initial treatment is completed, the likelihood of cancer recurrence is lowered by consistent use of Armotraz. Long-term use under medical supervision has demonstrated strong clinical outcomes in trials.
Clinical evidence suggests that Anastrozole may offer greater efficacy than older treatments such as tamoxifen in certain patients. It is particularly effective at preventing cancer recurrence in postmenopausal women. This makes it an important option in long-term breast cancer management.
For women with advanced breast cancer, Armotraz can slow tumour growth. It may help manage symptoms and improve quality of life over time. To achieve the best possible outcome, Armotraz must be taken regularly and exactly as your doctor instructs.
Armotraz also has a selective mechanism that reduces oestrogen without broadly disrupting other hormones. Because Armotraz targets a specific enzyme, it may be associated with fewer hormonal side effects than certain other treatments. How well your body responds to treatment will be assessed regularly by your medical team.
Alternative Medicine Doctors May Consider
Doctors may consider other aromatase inhibitors depending on your circumstances. Letrozole and Exemestane are two alternatives that act through a similar mechanism. Your oncologist will choose the most appropriate medicine for your individual case.
Tamoxifen is another hormone therapy sometimes used in breast cancer treatment. It works differently from aromatase inhibitors and may suit certain patients better. Some women may switch between treatments during their care pathway.
Your oncology team is best placed to discuss the full range of treatment options available for hormone receptor-positive breast cancer.
Possible Side Effects
Like any medicine, Armotraz may cause side effects. Because every patient’s body responds differently, both the nature and intensity of side effects can vary considerably. Always report troublesome or unexpected symptoms to your doctor.
| Frequency | Side Effect |
|---|---|
| Common | Hot flushes |
| Joint or muscle pain (arthralgia, myalgia) | |
| Nausea | |
| Loss of appetite | |
| Fatigue | |

| Headaches | |
| Mood changes | |
| Less Common | Osteoporosis or reduced bone density |
| Vaginal dryness or bleeding | |
| Raised cholesterol levels | |
| Skin reactions or itching | |
| Liver changes (detected through blood tests) | |
| Rare but Serious | Severe allergic reactions (hypersensitivity responses) — require urgent medical attention |
| Fragility fractures related to reduced bone density | |
| Severe joint swelling or inflammation |
Contact your GP if you notice signs of a severe allergic reaction. Signs include rash, swelling, breathing difficulties, or chest tightness. Symptoms that gradually worsen over time should never be left unreported.
Important Safety Advice
Before Armotraz is started, a full account of all existing medical conditions must be shared with your doctor. This is essential for your safety. Your doctor needs a full medical history to prescribe safely.
Tell your doctor if you have or have had any of the following:
- Osteoporosis or low bone density.
- Liver or kidney disease
- High cholesterol or cardiovascular conditions
- Lactose intolerance (Armotraz tablets contain lactose)
- Any known allergies to Anastrozole or its ingredients
Armotraz must not be taken by premenopausal women. Because Armotraz is designed for postmenopausal women, those who have not yet reached the menopause are unable to use this medicine safely. Your doctor will confirm your menopausal status before prescribing.
Pregnancy and breastfeeding
During pregnancy and breastfeeding, Armotraz must not be used under any circumstances. Serious harm to an unborn baby can result from taking this medicine during pregnancy, which is why its use is strictly contraindicated. Breastfeeding must be stopped before this medicine is started.
Bone health
Bone density may be reduced as a result of taking Anastrozole over a prolonged period. Your doctor may arrange a DEXA bone scan. This allows bone health to be monitored throughout the course of treatment. Alongside Armotraz, your doctor may advise taking calcium and vitamin D supplements to support bone strength.
Cholesterol monitoring
Armotraz may raise cholesterol levels in some women. Your doctor will likely arrange regular blood tests during treatment. Report any new chest pain or cardiovascular symptoms to your GP or NHS 111 promptly.
Drug interactions
All medicines currently being taken, including any started recently, should be disclosed to your doctor. All products being taken, whether prescription medicines, over-the-counter items, or herbal supplements, must be disclosed to your doctor. Oestrogen-containing medicines, including some HRT products, can reduce the effectiveness of Armotraz.
When Should You Speak to a Doctor?
Any symptoms that are new or that gradually worsen must be brought to your doctor’s attention promptly. Do not wait for your next scheduled appointment if you are concerned. Early communication with your medical team is always the right approach.
Speak to your GP or specialist if you notice:
- Severe joint or bone pain
- Signs of an allergic reaction
- Unexpected vaginal bleeding
- Chest pain or breathlessness
- Symptoms that significantly affect daily life
If your symptoms worsen during treatment, do not stop taking Armotraz without medical advice. Stopping suddenly may affect your treatment outcome. Always discuss any concerns with your oncologist or GP first.
