How to Inject Forteo Correctly
Forteo (teriparatide) comes as a prefilled pen for daily subcutaneous injections into the thigh or abdomen. Use it once a day at about the same time. Clean the injection site with an alcohol swab, insert the needle at a 45-90 degree angle, and inject slowly. Rotate sites to avoid irritation. Do not shake or freeze the pen.[1]
Step-by-Step Daily Use Instructions
- Wash hands thoroughly.
- Check pen: Ensure it's clear and colorless; discard if cloudy or expired.
- Prime the pen: Dial 2 units, hold button down until 0 shows, repeat until a drop appears (do this at first use and weekly).
- Dial 80 mcg (full dose), insert needle, press button fully, hold 5-10 seconds before removing.
- Dispose of needle in sharps container; pen lasts 28 days refrigerated (2-8°C).[1][2]
Treatment Duration and Schedule
Prescribed for maximum 2 years due to osteosarcoma risk. Inject within 8 hours of refrigeration removal; no meals needed, but consistent timing helps adherence.[1]
Storage and Handling Tips
Keep refrigerated until first use. After activation, store at room temperature (up to 25°C) for 28 days max, away from heat/light. Track start date on pen label.[2]
Common Mistakes to Avoid
- Skipping priming: Leads to underdosing.
- Injecting into arm, hip, or neck: Stick to thigh/abdomen.
- Using beyond 28 days or 2 years total: Increases risks without benefit.
- Reusing needles: Always new sterile one.[1][3]
What If I Miss a Dose?
Skip it and resume next day—do not double up. Contact doctor if multiple misses occur.[1]
Who Should Not Use Forteo
Avoid if history of bone cancer, radiation to skeleton, Paget's disease, hypercalcemia, or kids under 18 (black box warning for osteosarcoma risk). Not for osteoporosis prevention.[1][2]
Side Effects Patients Report Most
Dizziness, leg cramps, nausea (common). Rare: High calcium, allergic reactions. Report rapid heartbeat or swelling immediately. Monitor bone density via DEXA scans.[1][3]
