Proper use of Fortical nasal spray is important for its effectiveness. Always follow the specific instructions provided by your doctor and the medication packaging.

• Storage Before Opening: Unopened bottles of Fortical should be stored in the refrigerator (between 2° to 8°C or 36° to 46°F) and protected from freezing.
• Room Temperature: Before using a new bottle for the first time, allow it to reach room temperature.
• Priming the Pump: Before the first use of a new bottle, you need to “prime” the pump. Hold the bottle upright and press down on the two white side arms at least 5 times until a full spray is produced. Once primed, you do not need to prime it again before each daily use.
• Daily Dose: The recommended dose is one spray (200 International Units) into one nostril per day.
• Alternating Nostrils: It is best to alternate between using the right nostril one day and the left nostril the next day.
• No Inhaling while Spraying: Do not inhale deeply while spraying to avoid losing the dose.
• After Use: Wipe the nozzle with a clean tissue and replace the cap. After opening, store the bottle at room temperature (20° to 25°C or 68° to 77°F) in an upright position for up to 30 days. Discard the bottle after 30 doses, even if it’s not completely empty, to ensure you receive the correct dose.
• Missed Dose: If you miss a dose, use it as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not use extra medicine to make up for a missed dose.

Fortical (calcitonin-salmon) works by affecting bone metabolism. Calcitonin is a hormone that plays a role in regulating calcium levels in the body and bone remodeling.

• Inhibits Bone Resorption: Fortical’s primary action is to inhibit the activity of osteoclasts, which are the cells responsible for breaking down old bone tissue. By reducing bone breakdown, it helps to preserve existing bone density.
• Affects Calcium Levels: Calcitonin also influences calcium levels in the blood, leading to a small, temporary decrease in serum calcium after administration.
• Pain Relief: In some cases, calcitonin has also been observed to have a pain-relieving effect, particularly in patients experiencing acute pain from vertebral compression fractures, although Fortical is not specifically indicated for pain management.

By slowing down the rate at which bone is removed, Fortical helps to maintain the strength and density of bones, reducing the progression of osteoporosis.

Like all medications, Fortical can cause side effects, although not everyone experiences them. Most common side effects are typically related to nasal irritation.

• Common Side Effects (Nasal):
  • Rhinitis (runny or stuffy nose)
  • Nasal irritation, dryness, crusting, or sores inside the nose
  • Nosebleeds (epistaxis)
  • Sneezing
• Other Common Side Effects:
  • Headache
  • Back pain
  • Joint pain (arthralgia)
  • Nausea or vomiting (especially at the beginning of treatment)
  • Flushing of the face or hands
• Less Common/Serious Side Effects:
  • Allergic Reactions: Serious allergic reactions (including anaphylaxis, which can be life-threatening) are rare but possible. Symptoms include difficulty breathing, swelling of the face/tongue/throat, rash, severe dizziness. Seek immediate medical attention if these occur.
  • Hypocalcemia (Low Calcium Levels): Although rare, severe hypocalcemia with symptoms like muscle cramps, twitching, or seizures can occur. Pre-existing low calcium levels must be corrected before starting Fortical.
  • Malignancy Risk: Recent data suggest a potential, small increased risk of malignancy (cancer) with calcitonin-salmon use, which is why it’s reserved for specific patients. Your doctor will discuss this risk.

Report any persistent or severe side effects to your doctor.

Before using Fortical, and throughout treatment, several important warnings and precautions should be discussed with your healthcare provider.

• Risk of Malignancy: There is a potential increased risk of cancer with calcitonin-salmon nasal spray. Your doctor will weigh this risk against the benefits of treatment, particularly if alternative treatments are available and suitable.
• Hypersensitivity/Allergy: Do not use Fortical if you are allergic to calcitonin-salmon or any of its ingredients. Serious allergic reactions, including anaphylaxis, can occur. Skin testing may be considered for patients with suspected sensitivity.
• Hypocalcemia: Fortical should not be started in patients with low blood calcium levels (hypocalcemia). Any existing hypocalcemia or other disorders affecting mineral metabolism (like Vitamin D deficiency) must be corrected before starting treatment. Serum calcium levels may be monitored during therapy.
• Nasal Problems: Periodic nasal examinations are recommended before starting and during treatment, especially if you experience nasal discomfort, as nasal irritation, crusting, or ulceration can occur.
• Fracture Reduction Efficacy: Fortical’s ability to reduce the risk of non-vertebral fractures has not been demonstrated, and its fracture reduction efficacy is not as well-established as some other osteoporosis medications. It is often reserved for patients for whom other therapies are not appropriate.
• Pregnancy and Breastfeeding: Fortical is not indicated for use during pregnancy, and it is unknown if it passes into breast milk. Discuss with your doctor if you are pregnant, planning to become pregnant, or breastfeeding.
• Pediatric Use: The safety and effectiveness of Fortical have not been established in pediatric patients.

When using Fortical, it is important to inform your doctor about all other medications, supplements, and herbal products you are taking. While formal drug interaction studies with Fortical nasal spray are limited, some potential interactions have been noted.

• Lithium: Concomitant use of calcitonin (the active ingredient in Fortical) and lithium (used to treat certain mood disorders) may lead to a reduction in plasma lithium concentrations. Your doctor may need to monitor lithium levels and adjust its dose.
• Prior Bisphosphonate Use: In patients with Paget’s disease, prior use of diphosphonates (another class of osteoporosis drugs) appears to reduce the anti-resorptive response to calcitonin-salmon nasal spray. The effects of prior bisphosphonate use in postmenopausal osteoporosis patients have not been fully assessed, but it’s important to inform your doctor about all previous and current osteoporosis treatments.
• Calcium and Vitamin D: Fortical should be used in conjunction with adequate intake of calcium (at least 1000 mg elemental calcium per day) and Vitamin D (at least 400 International Units per day) as recommended by your doctor.

Always provide a complete and accurate list of all your medications to your healthcare provider.

The dosage of Fortical (calcitonin-salmon nasal spray) is specific and should be followed exactly as prescribed by your doctor.

• Recommended Dose: The standard recommended dose is one spray (200 International Units) per day intranasally.
• Alternating Nostrils: To help prevent nasal irritation, you should alternate nostrils daily. For example, spray into the left nostril on day one, and into the right nostril on day two, and so on.
• Timing: While the specific time of day is not critical, trying to use it around the same time each day can help with consistency.
• Supplemental Calcium and Vitamin D: It is crucial to take adequate calcium (at least 1000 mg elemental calcium per day) and Vitamin D (at least 400 International Units per day) as recommended by your doctor while using Fortical. These supplements are essential for bone health and to prevent hypocalcemia.
• Bottle Lifespan: Each bottle contains enough medication for at least 30 doses. Discard the bottle after 30 doses have been used, even if it appears to contain liquid, as subsequent sprays may not deliver the correct amount of medication.
• Missed Dose: If you miss a dose, take it as soon as you remember. If it’s almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not take a double dose.

Fortical is a prescription-only medication, meaning you cannot obtain it without a valid prescription from a licensed healthcare provider.

• Medical Diagnosis: A doctor’s evaluation is necessary to diagnose postmenopausal osteoporosis and to determine if Fortical is an appropriate treatment. This typically involves bone density tests (like DXA scans) and assessment of fracture risk.
• Patient Suitability: Fortical is generally reserved for women who are at least five years postmenopause and for whom other, often more potent, osteoporosis treatments are not suitable due to contraindications, intolerance, or unwillingness to use them. Your doctor will assess these factors.
• Exclusion of Hypocalcemia: Your doctor will need to ensure your blood calcium levels are normal before starting treatment, as hypocalcemia is a contraindication.
• Ongoing Monitoring: Due to the potential for nasal irritation and the slight, potential risk of malignancy, ongoing medical supervision and periodic check-ups with your doctor are required during treatment.
• Patient Education: Your doctor or pharmacist will provide detailed instructions on how to properly use the nasal spray and the importance of alternating nostrils, taking calcium and Vitamin D, and proper storage.
