Less Common Side Effects: Increased heart rate, shortness of breath, or swelling in the hands and feet. These symptoms may require medical attention.
Serious Side Effects: Hypercalcemia (high calcium levels), which can cause confusion, muscle weakness, or kidney problems. Seek medical help if you experience these symptoms.
Contraindications for Teriparatide Use
A contraindication is a specific condition where a medication should not be used due to potential harm. For Teriparatide, several contraindications should be discussed with your healthcare provider to ensure your safety.
Paget’s Disease of Bone: Teriparatide is contraindicated in patients with Paget’s disease, as it may increase the risk of bone cancer (osteosarcoma).
Unexplained High Levels of Alkaline Phosphatase: Elevated alkaline phosphatase levels may indicate an underlying bone condition, such as Paget’s disease, which could increase the risk of bone cancer when using Teriparatide.
History of Bone Cancer or Radiation Therapy to Bones: Teriparatide may raise the risk of osteosarcoma, particularly in patients with a history of bone cancer or radiation therapy involving the bones.
Hypercalcemia (High Calcium Levels): Teriparatide raises calcium levels, so it is contraindicated in patients with pre-existing high calcium levels, as this could lead to complications like kidney stones or cardiovascular issues.
Children and Adolescents: Teriparatide is not recommended for children or adolescents, as their bones are still growing, and the long-term effects in this group are not well understood.
Drug Interactions with Teriparatide
It’s important to inform your healthcare provider about all medications you are taking, as some may interact with Teriparatide, potentially causing harmful effects or reducing the effectiveness of your treatment. Below are some medications that may interact with Teriparatide:
Digoxin (Lanoxin): Teriparatide can increase calcium levels, which may enhance the effects of digoxin and raise the risk of digoxin toxicity.
Thiazide Diuretics (Hydrochlorothiazide, Microzide): These medications can also raise calcium levels, further increasing the risk of hypercalcemia when used with Teriparatide.
Calcium Supplements: Taking calcium supplements while on Teriparatide can lead to excessively high calcium levels, causing side effects like nausea, vomiting, and confusion.
Teriparatide in Pregnancy
Is it safe to take Teriparatide when pregnant?
Teriparatide is generally not recommended during pregnancy due to limited data on its safety in pregnant women. Animal studies have indicated potential risks to the fetus, including skeletal abnormalities. If you are pregnant or planning to become pregnant, it is important to discuss alternative treatments for osteoporosis with your healthcare provider. If you are currently taking Teriparatide and discover you are pregnant, contact your healthcare provider immediately to determine the most appropriate course of action.
Teriparatide While Breastfeeding
Is it safe to take Teriparatide while breastfeeding?
There is currently insufficient data on whether Teriparatide passes into breast milk or its potential effects on a nursing infant. Due to this lack of information, it is generally advised to avoid using Teriparatide while breastfeeding. If you are nursing, consult your healthcare provider to carefully weigh the risks and benefits of continuing Teriparatide or to explore alternative treatments for osteoporosis or other bone health conditions.
Estimated Cost of Teriparatide
The cost of Teriparatide can vary depending on your location and pharmacy. Without insurance, a 30-day supply of Teriparatide (brand name Forteo) using a GoodRx coupon is estimated to cost between $3,500 and $4,000. For the most accurate pricing, check with your pharmacy, and consider discussing financial assistance options with your healthcare provider if needed. Understanding the cost of Teriparatide is an important factor when planning your osteoporosis treatment.
Possible Alternatives to Teriparatide
If Teriparatide is not suitable for you, several alternative treatments and lifestyle changes may help manage your condition. Always consult your healthcare provider before making any changes to your treatment plan. You can also schedule a telemedicine appointment with one of our providers to discuss these alternatives.
Osteoporosis
Alternatives include bisphosphonates (such as Alendronate or Fosamax), denosumab (Prolia), or hormone replacement therapy (HRT). In addition, weight-bearing exercises, adequate calcium and vitamin D intake, and smoking cessation are essential lifestyle changes to support bone health.
Osteopenia
Lifestyle changes such as increasing physical activity, improving diet, and ensuring adequate calcium and vitamin D intake can help manage osteopenia. Bisphosphonates may also be considered as part of the treatment plan.
Hypoparathyroidism
Calcium and active vitamin D supplements are typically used to manage hypoparathyroidism. In some cases, recombinant parathyroid hormone (Natpara) may be prescribed as an alternative to Teriparatide.
Paget’s Disease
Bisphosphonates (such as Alendronate or Fosamax) or calcitonin (Miacalcin) are commonly used to manage Paget’s disease. Physical therapy and pain management strategies may also be beneficial.
Bone Fractures
In addition to Teriparatide, bisphosphonates or denosumab may be used to promote bone healing. Adequate calcium and vitamin D intake, along with physical therapy, can also aid recovery from bone fractures.
Osteogenesis Imperfecta
Bisphosphonates are often used to strengthen bones in patients with osteogenesis imperfecta. Physical therapy and mobility aids may also be recommended to improve quality of life.
Chronic Kidney Disease
Managing bone health in chronic kidney disease may involve phosphate binders, vitamin D analogs, and medications to control parathyroid hormone levels. It is important to consult a nephrologist to find the best treatment plan for your specific condition.
Glucocorticoid-Induced Osteoporosis
Bisphosphonates (such as Alendronate or Fosamax) or denosumab (Prolia) are often used to prevent bone loss in patients taking long-term glucocorticoids. Weight-bearing exercises and adequate calcium and vitamin D intake are also crucial for maintaining bone density.
Male Osteoporosis
Bisphosphonates (such as Alendronate or Fosamax), denosumab (Prolia), or testosterone replacement therapy (if low testosterone is a factor) may be considered. Lifestyle changes, including regular exercise and a balanced diet, are also beneficial for managing male osteoporosis.
Postmenopausal Osteoporosis
Bisphosphonates (such as Alendronate or Fosamax), denosumab (Prolia), or hormone replacement therapy (HRT) are common alternatives for postmenopausal osteoporosis. Weight-bearing exercises, along with calcium and vitamin D supplementation, are also recommended to support bone health.
Recent Updates on Teriparatide Research
Recent studies have focused on the long-term safety and effectiveness of Teriparatide, particularly in reducing fracture risk in osteoporosis patients. A 2022 study published in the Journal of Bone and Mineral Research found that Teriparatide significantly reduced the risk of both vertebral and non-vertebral fractures in postmenopausal women with severe osteoporosis. Additionally, ongoing research is exploring the use of Teriparatide in combination with other osteoporosis treatments, such as denosumab, to further enhance bone density and reduce fracture risk.
Another area of interest is the use of Teriparatide in patients with glucocorticoid-induced osteoporosis. A 2021 study showed that Teriparatide was more effective than bisphosphonates in increasing bone mineral density in this population. However, more research is needed to determine the long-term outcomes of this treatment approach.
Staying informed about the latest research is essential. Discuss any new developments with your healthcare provider. If you have questions about Teriparatide or want to explore other osteoporosis treatment options, schedule a telemedicine appointment with one of our providers today.
