When Oral Iron Is Not Enough
Iron deficiency is one of the most common nutritional deficiencies in the United States, affecting energy, breathing, cognitive function, and overall quality of life. For many patients, oral iron supplements cause significant gastrointestinal side effects — nausea, constipation, cramping — and absorb poorly, particularly in patients with inflammatory bowel disease, celiac disease, post-bariatric surgery anatomy, or chronic blood loss.
IV iron bypasses the digestive tract entirely. The full therapeutic dose enters your bloodstream directly, replenishing iron stores faster and more completely than oral supplementation can achieve in patients who cannot tolerate or absorb it adequately.
At Evergreen Factor in Lake Oswego, Dr. Tomas Gigena, M.D. administers physician-supervised IV iron infusions with trace minerals — a clinical-grade protocol ordered based on individual patient need, with mandatory physician evaluation before every course of treatment.
What Is IV Iron Infusion Therapy?
Iron is essential for the production of hemoglobin, the protein in red blood cells that carries oxygen from your lungs to every tissue in your body. When iron stores are depleted, hemoglobin production falls, red blood cells become smaller and less effective, and oxygen delivery to muscles, organs, and the brain becomes compromised.
The result is iron deficiency anemia — characterized by persistent fatigue, shortness of breath with minimal exertion, brain fog, pale skin, cold hands and feet, brittle nails, and reduced exercise tolerance.
IV iron infusion delivers iron directly into the bloodstream, where it is immediately available for red blood cell production and iron store replenishment. Unlike oral iron, which must be absorbed through the gastrointestinal tract and is subject to significant first-pass losses, intravenous delivery achieves complete bioavailability with a single session.
At Evergreen Factor, each iron infusion also includes trace minerals — supporting the enzymatic cofactors involved in iron metabolism and overall cellular function. We use, a pharmaceutical-grade administered under strict medical supervision to ensure safety, precision, and optimal iron repletion.
Who Needs IV Iron Infusion?
Dr. Gigena evaluates every patient individually before ordering IV iron. Patients who may benefit from IV iron infusion therapy at Evergreen Factor include those experiencing the following.
Iron deficiency anemia unresponsive to oral supplementation. Patients who have tried oral iron and cannot tolerate the side effects, or whose iron levels have not improved adequately despite consistent supplementation, are often candidates for IV iron therapy.
Malabsorption conditions. Patients with celiac disease, Crohn's disease, ulcerative colitis, or post-bariatric surgery anatomy frequently cannot absorb adequate iron through the gastrointestinal tract regardless of oral dose.
Chronic blood loss. Heavy menstrual bleeding, gastrointestinal bleeding, or other sources of ongoing blood loss can deplete iron stores faster than oral supplementation can replenish them.
Pregnancy-related iron deficiency. Iron requirements increase significantly during pregnancy. When oral iron is insufficient or poorly tolerated, IV iron provides a safe and effective alternative under physician supervision.
Pre-surgical iron optimization. Patients scheduled for elective surgery who present with iron deficiency anemia may benefit from IV iron to optimize hemoglobin levels before the procedure.
Chronic kidney disease. Patients on dialysis or with chronic kidney disease frequently develop iron deficiency due to reduced erythropoietin production and blood loss during dialysis.
Persistent fatigue and reduced exercise tolerance. Athletes and high-performing individuals with suboptimal iron stores — even without frank anemia — may experience meaningful improvements in energy, endurance, and recovery with IV iron repletion.
Evergreen Factor serves patients from Lake Oswego, Portland, West Linn, Tualatin, Tigard, Beaverton, Oregon City, and throughout Clackamas and Multnomah counties.
Why IV Iron Outperforms Oral Supplementation
Oral iron has two fundamental limitations that IV iron eliminates entirely.
Bioavailability. The gastrointestinal tract absorbs only a fraction of oral iron — typically 10 to 20 percent under ideal conditions, and far less in patients with inflammatory bowel disease, reduced stomach acid, or post-surgical anatomy. IV iron delivers the complete dose directly to circulation with no digestive loss.
Tolerability. Oral iron is notorious for causing nausea, constipation, abdominal cramping, and dark stools. Many patients reduce their dose or discontinue supplementation entirely due to these side effects, undermining treatment. IV iron produces none of these gastrointestinal effects.
The addition of trace minerals in Evergreen Factor's protocol supports the enzymatic pathways involved in iron utilization — including copper-dependent ceruloplasmin, which is essential for iron mobilization from storage sites — providing a more comprehensive approach to iron repletion than iron alone.
The Evergreen Factor Iron Infusion Protocol
Mandatory physician evaluation. Every patient must complete a medical pre-screen with Dr. Tomas Gigena, M.D. before any iron infusion is ordered. Dr. Gigena reviews your complete health history, current medications, recent laboratory values, and clinical presentation to determine whether IV iron is appropriate for your situation and which dose tier fits your needs. Iron infusions at Evergreen Factor are ordered based on availability and individual clinical need — not on request alone.
Laboratory review. Iron infusion therapy requires confirmation of iron deficiency through laboratory testing. Dr. Gigena reviews ferritin, serum iron, total iron binding capacity, transferrin saturation, and complete blood count to establish your baseline and determine the appropriate dose.
IV infusion session. The infusion is administered over approximately 45 to 60 minutes in a comfortable clinical setting at our Lake Oswego facility. A licensed nurse places the IV and monitors you throughout the session. Dr. Gigena is on-site or immediately on-call during all treatment hours.
Post-infusion monitoring. You are observed for a brief period following the infusion before discharge. Most patients return to normal activities immediately. Temporary darkening of urine or stool may occur and is expected.
Follow-up laboratory assessment. Dr. Gigena recommends follow-up iron studies at approximately four to six weeks post-infusion to assess response and determine whether additional sessions are indicated.

Safety, Contraindications, and Physician Oversight
IV iron has a well-established safety profile when administered under physician supervision with appropriate patient screening. Dr. Gigena evaluates every patient for the following before ordering treatment.
Absolute contraindications: Known hypersensitivity or previous anaphylactic reaction to IV iron compounds. Iron overload conditions including hemochromatosis or hemosiderosis. Active bacterial infection — IV iron may worsen outcomes in the setting of active infection by providing substrate for bacterial growth.
Relative contraindications requiring medical clearance: First trimester of pregnancy. Severe hepatic impairment. Asthma or multiple drug allergies — increased risk of hypersensitivity reactions. Rheumatoid arthritis with active inflammation.
Potential drug interactions: IV iron may reduce the absorption of oral medications including levothyroxine, quinolone antibiotics, and tetracyclines when taken in close proximity. Concurrent use of ACE inhibitors may increase the risk of systemic reactions. Dr. Gigena reviews all current medications at your pre-screen.
Monitoring during infusion: All patients are monitored by licensed nursing staff throughout the infusion. Dr. Gigena is on-site or immediately on-call. Emergency protocols, crash cart, and defibrillator are maintained on-site at all times. Direct referral relationships with Providence St. Vincent Medical Center and Legacy Meridian Park Medical Center for emergency transfer when needed.
Expected side effects: Mild and transient side effects may include temporary darkening of stool or urine, a metallic taste during infusion, mild headache, or temporary joint discomfort in the 24 to 48 hours following infusion. These are expected and resolve without intervention.
Frequently Asked Questions
Q: How do I know if I need an iron infusion?
A: The first step is a consultation with Dr. Gigena, who will review your symptoms and order or review laboratory values including ferritin, serum iron, transferrin saturation, and complete blood count. IV iron is ordered based on clinical need — not all patients presenting with fatigue will require it, and not all iron deficiency requires IV treatment.
Q: How quickly will I feel results?
A: Most patients begin noticing improvements in energy and exercise tolerance within one to three weeks of their infusion as hemoglobin production increases and iron stores are replenished. Full response is typically assessed at four to six weeks with follow-up laboratory testing.
Q: How many infusions will I need?
A: This depends entirely on your baseline iron studies, the cause of your deficiency, and your clinical response. Some patients achieve adequate repletion with a single session. Others with ongoing blood loss or malabsorption require periodic maintenance infusions. Dr. Gigena determines frequency based on your laboratory values and clinical response.
Q: Does insurance cover IV iron infusion?
A: Coverage varies by plan and clinical indication. IV iron infusion for documented iron deficiency anemia may be covered under some insurance plans when ordered by a physician with supporting laboratory values. Evergreen Factor can provide itemized receipts for submission to your insurer. HSA and FSA funds may also apply. Confirm coverage directly with your plan administrator before scheduling.
Q: Can I combine iron infusion with other therapies at Evergreen Factor?
A: In many cases yes, depending on your clinical presentation. IV glutathione pairs well with iron infusion to support antioxidant defense during the repletion process. Dr. Gigena will advise on appropriate combinations at your pre-screen based on your health history and treatment goals.
Q: Is the physician pre-screen required every time?
A: A comprehensive evaluation is required for all new patients. Established patients receive ongoing monitoring at the frequency Dr. Gigena determines appropriate, with laboratory review guiding repeat dosing decisions.
