How Forteo Is Administered

Forteo (teriparatide) is given as a daily subcutaneous injection using a prefilled, disposable pen device. Patients self-administer one 20-microgram dose each day, typically into the thigh or abdomen, rotating sites to avoid irritation. The pen delivers a fixed dose with a simple push-button mechanism—no needles are handled separately.[1]

Step-by-Step Injection Process

1. Wash hands and clean the injection site with an alcohol swab.
   
2. Remove the pen cap and attach a new disposable needle (included with each pen).
   
3. Turn the dial to select the 20 mcg dose.
   
4. Insert the needle subcutaneously at a 45- to 90-degree angle.
   
5. Press the injection button fully until the dose counter shows zero, hold for 5-10 seconds to ensure delivery, then withdraw.
   Treatment lasts up to 2 years maximum, after which it's discontinued to avoid risks like osteosarcoma.[1][2]
   
   

Who Can Administer It and Training

Patients or caregivers administer at home after healthcare provider training. No refrigeration needed after first use; store at room temperature for up to 28 days. Each pen holds 28 doses (one month).[1]

Common Patient Questions on Use

Does it hurt? Most report mild stinging, like a pinch; numbing the site helps.

What if I miss a dose? Skip it and resume the next day—do not double up.

Storage mishaps? Discard if exposed to heat over 86°F (30°C) or light.[1][2]

Travel tips? Pens are portable; declare at security if needed; no special airline rules beyond liquids limit.

Why This Delivery Method

Subcutaneous injection ensures steady absorption of the parathyroid hormone fragment, mimicking natural bone-building pulses better than pills, which degrade in the gut.[1]
