Calcitonin nasal spray is easy to apply and usually given once a day. Listed below are the general instructions for administration of this medication:

Preparation: Prior to using for the first time, prime the nasal spray bottle. The bottle should be shaken well. Spray the bottle into the air until a fine mist appears. This ensures the device is working properly.

Administration:

Step 1: Gently blow your nose to clear the nasal passages.

Step 2: Shake the nasal spray bottle well before use.

Step 3: Insert the nozzle into one nostril while keeping the other nostril closed. Spray the prescribed dose of medication into the nostril.

Step 4: After administering the spray, breathe in gently through your nose to help absorb the medication.

Step 5: Repeat the process for the other nostril, if required by your healthcare provider.

Storage: The nasal spray should be stored at room temperature and away from heat or direct sunlight. Do not freeze the spray, and ensure the bottle is tightly closed when not in use.

The primary mechanism of action of calcitonin nasal spray revolves around its ability to reduce bone resorption and help maintain bone density:

It works by binding calcitonin to specific receptors present on the surface of the osteoclasts, responsible for the destruction of the bone tissue. This further results in inhibition of activity of the osteoclasts and slows down bone resorption.

Reduction of Calcium Release: Osteoclasts are inhibited by calcitonin to reduce the release of calcium from bones into the blood. This is very effective in conditions with increased breakdown of bones or where the risk of calcium elevation in the blood is concerned.

The reduction in the breakdown of bones is yet another mode through which calcitonin contributes to the regulation of calcium balance. It ensures calcium excretion through the kidneys, which further lowers the levels of blood calcium in the case of hypercalcemia.

Calcitonin nasal spray is generally well-tolerated; however, it may produce side effects, especially if the medication is taken for an extended period of time. Common and less common side effects are listed below:

Nasal Irritation: The common side effect is irritation in the nose, such as nasal congestion, runny nose, or a dry nose.

Headache: Users may develop headaches, particularly when beginning treatment.

Back Pain: Some people develop mild back pain or muscle aches due to treatment.

Allergic Reactions: Rarely, some individuals may develop allergic reactions to calcitonin, such as rash, swelling, or more severe symptoms like trouble breathing. In case an allergic reaction is developed, one should seek medical care.

Hypocalcemia: In rare cases, the levels of calcium can drop significantly from the use of calcitonin, causing symptoms that resemble hypocalcemia. The symptoms include muscle cramps, tingling or numbness in the fingers or toes.

Nausea: Some people may develop nausea or discomfort in the gastrointestinal area.

Important warnings and precautions in the use of calcitonin nasal spray include the following:

Allergic Reactions. The patient who is allergic to salmon calcitonin or fish proteins should not take this drug.

Pregnancy and Breastfeeding: The safety of calcitonin during pregnancy and breastfeeding has not been fully established. It is classified as a Category C drug. Therefore, it should only be used if the potential benefit justifies the risk to the fetus or infant. Pregnant and breastfeeding women should consult their healthcare provider before starting this treatment.

Renal Impairment: Patients with renal diseases or impaired renal functions may need caution because calcitonin will affect calcium metabolism as well as the functions of kidneys.

Long-term therapy with calcitonin could pose risks of losing the drugs efficacy, and patients should be carefully watched for changes in bone densities as well as other health issues.

Lithium: Lithium, used in the treatment of bipolar disorder, may increase the risk of thyroid toxicity when used with calcitonin. The two medications may interact by affecting calcium levels, so monitoring calcium and thyroid function is recommended.

Bisphosphonates: Calcitonin nasal spray and bisphosphonates (e.g., alendronate) are both used to treat osteoporosis. While they work through different mechanisms, combining them could increase the risk of side effects like hypocalcemia (low calcium levels). Monitoring calcium levels and kidney function is advised.

Vitamin D and Calcium Supplements: Since calcitonin affects calcium regulation, using it with calcium and Vitamin D supplements (e.g., Calcium 500 + D) may influence calcium balance. Monitoring blood calcium levels is recommended to avoid hypocalcemia or hypercalcemia.

Estrogen: Estrogen therapy (e.g., hormone replacement therapy) can have a synergistic effect with calcitonin in promoting bone health. However, the combination may increase the risk of side effects, including potential calcium imbalance. Regular monitoring of calcium levels is important.

The standard osteoporosis dosage is:

1 spray (200 IU) once daily, in one nostril. The patient should alternate between nostrils for each spray, unless advised otherwise by a healthcare provider.

The dosage can be adjusted depending on the severity of the condition, the response of the patient to the treatment, and side effects.

Calcitonin nasal spray is prescription only. The patient should be evaluated by a health care provider who would assess his condition, estimate the fracture risk, and determine whether calcitonin would be appropriate for the treatment. Continuous monitoring of the patient’s bone health and calcium level should also be done during treatment.

1. What is Calcitonin nasal spray?

   • Calcitonin nasal spray is a medication that delivers a synthetic version of the hormone calcitonin directly to the nasal mucosa, used primarily to treat osteoporosis and other bone-related conditions.

2. How does Calcitonin nasal spray work?

   • It helps lower blood calcium levels and inhibits bone resorption by osteoclasts, thereby supporting bone density and reducing the risk of fractures.

3. What conditions are treated with Calcitonin nasal spray?

   • It is mainly used for treating postmenopausal osteoporosis and may also be used for conditions such as Paget’s disease and hypercalcemia.

4. How is Calcitonin nasal spray administered?
