Finding the Right Doctor for Saizen

If you or your child has been diagnosed with growth hormone deficiency — or you suspect it — one of the first challenges is finding a doctor who can prescribe Saizen (Somatropin). Growth hormone therapy isn't something every doctor handles, and the prescribing process involves testing, prior authorizations, and specialty pharmacies.

This guide walks you through exactly how to find the right provider, what to expect at your appointment, and how to move from diagnosis to prescription as smoothly as possible.

What Type of Doctor Prescribes Saizen?

Saizen is a recombinant human growth hormone used to treat both pediatric and adult growth hormone deficiency. Because of its specialized nature, only certain providers typically prescribe it:

• Endocrinologists — The most common prescribers. These specialists focus on hormone-related conditions and are the go-to for adult growth hormone deficiency (GHD).
• Pediatric Endocrinologists — For children with growth failure due to inadequate growth hormone secretion. They manage the entire treatment process from diagnosis through adolescence.
• Pediatricians — While they may initiate testing for short stature, most will refer to a pediatric endocrinologist for actual prescribing.
• Internal Medicine Physicians — Some internists with experience in hormonal disorders may prescribe growth hormone therapy for adults.

In most cases, you'll need to see an endocrinologist to get a Saizen prescription. Primary care doctors can start the conversation and order initial lab work, but the actual prescribing and monitoring almost always involves a specialist.

How to Find a Provider

1. Check Your Insurance Directory

Start with your insurance company's provider directory. Log into your plan's website or call the member services number on your insurance card. Search for "endocrinology" in your area and confirm the doctor is accepting new patients. This ensures you'll have in-network coverage, which matters a lot when Saizen can cost $800 to $3,000+ per month.

2. Use Online Search Tools

Several platforms make it easy to find endocrinologists near you:

• Zocdoc — Filter by specialty, insurance, and availability. Book appointments directly online.
• Healthgrades — Read patient reviews and check board certifications.
• Vitals.com — Compare doctors by ratings, wait times, and conditions treated.
• Your hospital system's website — Many academic medical centers list their endocrinology department and areas of expertise.

3. Ask for a Referral

Your primary care doctor is often the best starting point. They can:

• Order preliminary blood work (IGF-1 levels, thyroid function)
• Refer you to a trusted endocrinologist they've worked with
• Start the documentation trail that insurance companies will want to see

If your insurance plan is an HMO, you'll likely need a referral before seeing a specialist. Even with PPO plans, having your PCP's referral can speed things up.

4. Contact EMD Serono Patient Support

EMD Serono, the manufacturer of Saizen, offers patient support programs that can help connect you with prescribing physicians in your area. Visit emdserono.com or call their patient support line for assistance finding a provider experienced with Saizen specifically.

5. Consider Academic Medical Centers

University-affiliated hospitals often have endocrinology departments with extensive experience in growth hormone therapy. They may also participate in clinical trials and have access to the latest treatment protocols. If you're in a rural area, these centers may be worth the drive.

What to Expect at Your First Appointment

Getting a Saizen prescription isn't a one-visit process. Here's what typically happens:

Initial Evaluation

• Medical history review — The doctor will ask about symptoms, growth patterns (for children), previous hormone testing, and any history of pituitary conditions, surgery, or radiation.
• Physical exam — Height, weight, body composition measurements, and assessment of growth velocity in children.
• Blood work — IGF-1 and IGFBP-3 levels are typically checked first. Low levels suggest possible GHD but aren't diagnostic alone.

Diagnostic Testing

Insurance companies require provocative growth hormone stimulation testing before approving Saizen. This involves:

• Administering a stimulus (such as insulin, glucagon, or arginine) that should trigger GH release
• Drawing blood at intervals to measure your growth hormone response
• A peak GH level below a certain threshold confirms deficiency

For adults, an MRI of the pituitary gland is also commonly ordered to check for structural abnormalities.

Getting the Prescription

Once GHD is confirmed, your doctor will:

1. Determine the appropriate Saizen dose (adults typically start at 0.2 mg/day)
2. Submit a prior authorization request to your insurance
3. Coordinate with a specialty pharmacy for dispensing (Saizen is rarely available at retail pharmacies)
4. Schedule injection training so you can self-administer at home

After You Get Your Prescription

Once you have your Saizen prescription, there are a few more steps:

• Learn to reconstitute and inject — Saizen comes as a lyophilized powder that must be mixed with bacteriostatic water before injection. Your doctor's office or specialty pharmacy will train you.
• Know your costs — Even with insurance, co-pays for specialty medications can be significant. Check out our guide to saving money on Saizen for coupon cards and patient assistance programs.
• Find a pharmacy with stock — Saizen is distributed through specialty pharmacies, so availability can vary. Use Medfinder to check which pharmacies have it in stock.
• Schedule follow-ups — You'll typically see your endocrinologist every 1-3 months initially to monitor IGF-1 levels, adjust dosing, and check for side effects.

Final Thoughts

Finding a doctor who prescribes Saizen takes a bit more effort than getting a typical prescription, but the process is straightforward once you know the steps. Start with your primary care doctor or insurance directory, get to an endocrinologist, and be prepared for diagnostic testing before treatment begins.

The most important thing is working with a specialist who has experience with growth hormone therapy and can guide you through the prior authorization process. If you're ready to start your search, Medfinder can help you find pharmacies and resources to make the journey easier.
