Gonal F 900 IU Pen (Follitropin Alfa) – Buy Online
Gonal F 900 IU Pen is the largest pre-filled follitropin alfa injection available, designed for patients requiring high-dose or extended IVF stimulation protocols.
What is Gonal F 900 IU Pen?
Gonal F 900 IU contains follitropin alfa, a synthetic FSH hormone that stimulates your ovaries to produce multiple eggs during IVF treatment. The 900 IU pen is the highest-dose option available, perfect for patients who need extended stimulation or higher daily doses throughout their cycle.
Why Choose the 900 IU Pen?
- Best value for high-dose protocols (saves money vs. multiple smaller pens)
- Fewer pen changes during treatment
- Precise dosing from 12.5 IU to 900 IU
- Convenient subcutaneous self-injection
- European-manufactured quality standards
Many fertility clinics prescribe the 900 IU pen for patients over 35, those with diminished ovarian reserve, or anyone requiring doses above 225 IU daily.
Gonal F 900 vs 450 vs 300: Which Size Do You Need?
Fast IVF offers three Gonal F pen strengths:
| Pen Size | Total Medication | Best For |
|---|---|---|
| Gonal F 300 IU | 300 IU total | Low-dose protocols, younger patients |
| Gonal F 450 IU | 450 IU total | Standard protocols, moderate doses |
| Gonal F 900 IU | 900 IU total | High-dose protocols, longer cycles, best value |
Example: If your doctor prescribes 225 IU daily for 10 days, you’d need 2,250 IU total. The 900 IU pen gives you the most medication in one device, reducing waste and saving money.
How Does Gonal F 900 Work?
The follitropin alfa in Gonal F 900 IU Pen mimics your natural FSH hormone. It stimulates multiple follicles in your ovaries to develop simultaneously. This gives your fertility team more mature eggs to retrieve, improving your chances of IVF success.
Your doctor monitors your response through:
- Blood tests (estradiol levels)
- Ultrasounds (follicle count and size)
- Dosage adjustments as needed
Most patients start seeing follicles develop within 5-7 days of beginning treatment.

Is the 900 IU pen better value than smaller sizes?
Yes, typically. The 900 IU pen offers the most medication per device, making it more cost-effective for high-dose protocols. For example, if you need 300 IU daily for 10 days (3,000 IU total), buying one 900 IU pen plus other sizes costs less than buying multiple smaller pens. Your doctor determines which size works best for your protocol.
Can I use Gonal F 900 for multiple IVF cycles?
Possibly, if you have medication left over. Once opened, Gonal F pens stay good for 28 days when refrigerated. If your first cycle gets canceled or you use less than prescribed, you may be able to use remaining medication for your next cycle. Always check with your doctor first and verify the medication hasnt expired.
How long does the 900 IU pen last?
It depends on your daily dose. Common examples:
- 150 IU daily = 6 days of medication
- 225 IU daily = 4 days of medication
- 300 IU daily = 3 days of medication
Most patients need multiple pens for a complete IVF cycle. Your doctor calculates your total medication needs based on your protocol.
Is Gonal F 900 the same as Follistim?
Both contain follitropin alfa and work identically. Gonal F and Follistim are simply different brand names for the same medication. The 900 IU pen format is specific to Gonal F. Many doctors prescribe one over the other based on availability, cost, or personal preference.
What if I experience side effects?
Common side effects include mild bloating, headaches, injection site reactions, and mood changes. These are similar across all IVF medications. Contact your doctor immediately if you experience severe abdominal pain, rapid weight gain, difficulty breathing, or decreased urination – these may indicate ovarian hyperstimulation syndrome (OHSS).
