Ostospray 3.7 mL Nasal Solution

Ostospray 3.7 mL Nasal Solution is a prescription nasal spray that contains calcitonin (salmon), a synthetic hormone-like medicine used to help treat osteoporosis. Each dose of Ostospray 3.7 mL Nasal Solution delivers 3.7 mL of nasal solution as directed by your prescriber, and it belongs to the calcitonin class of medicines. It is used to help reduce bone loss and lower fracture risk in some people with osteoporosis, especially when other options are not suitable.

How it works: Calcitonin (salmon) helps slow the activity of cells that break down bone, which can help preserve bone density over time. As a nasal spray, Ostospray 3.7 mL Nasal Solution is absorbed through the lining of the nose after spraying, so it does not need to be swallowed.

Because Ostospray 3.7 mL Nasal Solution is supplied as a 3.7 mL nasal spray and there are no other strengths or forms listed for this brand here, it is used exactly as prescribed rather than being matched to a lower or higher sibling strength. A doctor may choose this nasal spray form when a patient needs calcitonin in a non-tablet option and can use a nose spray consistently.

• Treatment of osteoporosis
• Help reduce bone loss
• May lower risk of certain fractures
• Bone health support when prescribed by a doctor

• Use Ostospray 3.7 mL Nasal Solution exactly as prescribed; do not use extra sprays to make up for a missed dose unless your doctor tells you to.
• Prime the spray and follow the package instructions before first use or if it has not been used for several days.
• Spray into one nostril as directed, usually alternating nostrils from dose to dose if your prescriber instructs you to.
• Try to use it at the same time each day for consistent dosing.
• Avoid blowing your nose right after using the spray unless your doctor or pharmacist says otherwise.
• If you miss a dose, take it when you remember unless it is almost time for the next dose; do not double up.

Ostospray 3.7 mL Nasal Solution provides 3.7 mL per dose as supplied in the product pack, and the exact number of sprays or the dosing schedule is determined by your prescriber. Calcitonin nasal products are typically taken once daily, but your doctor may adjust how often you use this specific 3.7 mL spray based on your condition and response, up to the maximum recommended daily use on the label.

Do not change your dose or stop the medicine without speaking to your doctor.

Common side effects of Calcitonin (Salmon) may include:

• Runny or stuffy nose
• Nasal irritation or dryness
• Sneezing
• Headache
• Back pain

• Do not use if you have had an allergy to calcitonin (salmon) or any ingredient in the spray.
• Tell your doctor if you have frequent nosebleeds, nasal surgery, or chronic nasal problems before using this spray.
• Use caution if you have low calcium levels or are at risk for calcium imbalance.
• If you are pregnant or breastfeeding, ask your doctor whether this medicine is appropriate for you.
• This medicine is not for immediate pain relief; it works over time to help manage osteoporosis.
• Tell your clinician about kidney disease, because overall treatment planning for osteoporosis may need adjustment.
• Do not use more often than prescribed, since higher-than-directed use may increase nasal side effects.

• Other medicines that affect calcium levels, including calcium supplements or vitamin D products, may need monitoring.
• Lithium may interact with calcitonin and may require closer follow-up.
• Other osteoporosis medicines should be reviewed so your prescriber can choose the safest treatment plan.
• Nasal decongestants or medicated nasal sprays may affect how well the spray is used if taken at the same time.
