What medicines treat osteoporosis?
In the UK, the goal of osteoporosis medication is to strengthen existing bone, increase bone mineral density, and, most importantly, reduce the risk of fractures. Because bone is a living tissue that is constantly being broken down and rebuilt, most treatments work by altering this “remodelling” cycle. Your doctor will choose a medicine based on the severity of your bone loss, your age, and your general health. According to NICE guidelines, treatment is typically offered to those with a confirmed diagnosis on a DEXA scan or those who have already experienced a “fragility fracture.”

Bisphosphonates are the most frequently prescribed medicines.
Bisphosphonates are a group of medicines that slow down the rate at which bone is broken down (resorption). By slowing this process, the bone-building cells have more time to strengthen the bone matrix.
Commonly used bisphosphonates in the UK include:
- Alendronic acid (Alendronate): Taken as a weekly tablet.
- Risedronate: Usually taken as a weekly or monthly tablet.
- Ibandronic acid: Taken as a monthly tablet or an injection every three months.
- Zoledronic acid (Zometa/Aclasta): Given as a once-yearly intravenous infusion in a hospital or clinic.
According to the NHS, oral bisphosphonates must be taken on an empty stomach with a full glass of water, and you must remain upright for at least 30 minutes to prevent irritation to the oesophagus.
Biological therapies offer targeted bone protection.
For individuals who cannot tolerate bisphosphonates or for whom they are not effective, “biological” medicines may be used. These are usually given by injection.
- Denosumab (Prolia): This is a monoclonal antibody that targets a specific protein involved in bone breakdown. It is given as an injection just under the skin once every six months. It is highly effective but must be taken consistently; stopping it without a follow-up treatment can lead to a rapid drop in bone density.
- Romosozumab (Evenity): This is a newer “dual-action” medicine that both increases bone formation and reduces bone breakdown. It is usually reserved for post-menopausal women at very high risk of fracture and is given as monthly injections for one year.
Bone-building (Anabolic) medications for severe cases.
While most osteoporosis drugs slow down bone loss, Teriparatide (a form of parathyroid hormone) actually stimulates the body to build new, high-quality bone.
In the UK, Teriparatide is generally reserved for people with very low bone density who have already suffered multiple fractures. It is self-administered as a daily injection for up to two years. Once the course is finished, another medicine (like a bisphosphonate) is usually started to “lock in” the new bone that has been built.
Hormonal treatments for post-menopausal bone health.
Because the drop in oestrogen after menopause is a leading cause of bone loss, hormonal treatments can be an effective preventative measure.
- Hormone Replacement Therapy (HRT): While primarily used for menopausal symptoms, HRT is very effective at maintaining bone density. In the UK, it is often recommended for younger post-menopausal women to prevent future osteoporosis.
- Raloxifene (Evista): This is a Selective Oestrogen Receptor Modulator (SERM). It mimics the protective effects of oestrogen on the bones without affecting the breast or uterus in the same way. It is typically taken as a daily tablet.
Calcium and Vitamin D are essential companions to medication.
Medicines for osteoporosis can only work effectively if the body has the necessary building blocks to make new bone. Most patients in the UK will be prescribed a combined Calcium and Vitamin D supplement (such as Adcal-D3 or Accrete D3) alongside their main treatment.
The Royal Osteoporosis Society notes that even if you have a good diet, these supplements ensure that your blood levels remain steady, allowing the osteoporosis medication to function at its full potential.
Conclusion
The treatment of osteoporosis in the UK involves a variety of medicines, ranging from weekly bisphosphonate tablets to yearly infusions and daily “bone-building” injections. The choice of treatment is personalised to your specific risk of fracture and medical history. While these medicines are highly effective, they work best when combined with a healthy diet and weight-bearing exercise. If you are concerned about side effects or how to take your medication correctly, seek a medical review. If you experience severe, sudden, or worsening symptoms, call 999 immediately.
How long do I need to stay on osteoporosis medicine?
Many people take bisphosphonates for 3 to 5 years. After this, your doctor may suggest a “treatment holiday” where you stop the medicine for a while, as its protective effects can last in the bone for several years.
Do these medicines have side effects?
Common side effects of tablets include indigestion or heartburn. Injections may cause short-term “flu-like” symptoms. Rare risks, such as issues with the jawbone, are discussed by your doctor but are statistically very uncommon compared to the risk of a hip fracture.
Can I stop taking Denosumab if I feel better?
No, you should never stop Denosumab without medical advice. Stopping it abruptly can cause a “rebound effect” where bone density drops quickly, increasing your fracture risk.
Will the medicine make my bones feel different?
You won’t “feel” the medicine working, as bone density changes happen slowly over months and years. Its success is measured by future DEXA scans.
Is HRT safe for long-term bone protection?
For most women, the benefits of HRT for bone health outweigh the risks, especially if started early in the menopause. Your GP will discuss your individual risk profile.
Can I take these medicines if I have kidney problems?
Some osteoporosis drugs are not suitable for people with significant kidney disease. Your doctor will check your blood tests before prescribing.
Does strontium ranelate still get used?
In the UK, strontium ranelate is now rarely used and is reserved for people with severe osteoporosis who cannot use any other treatments, due to concerns about cardiovascular risks.
