Flu season places increased demand on the immune system—particularly for individuals under chronic stress, managing inflammation, or recovering from nutrient depletion. While viral illnesses are common, recovery time and symptom severity vary widely depending on immune resilience, metabolic health, and physiologic reserve.

At hhc+, we take an evidence-informed functional medicine approach to flu season. Rather than over-stimulating the immune system or relying solely on symptom suppression, our focus is on supporting appropriate immune response, respiratory function, and recovery using clinically grounded interventions.

How hhc+ Supports You During Flu Season

At hhc+, we offer two levels of immune support, depending on your needs:

Walk-in care for rapid hydration, symptom support, and respiratory relief
This includes drips, injections, and nebulized treatments when clinically appropriate. Walk-in services are designed to support recovery during acute illness or early symptoms without requiring long-term enrollment.

Deeper membership-based care for patients who get sick frequently, recover slowly, or want a proactive immune-resilience plan
Membership allows for comprehensive evaluation, prescription support when indicated, and a personalized strategy focused on prevention, recovery, and long-term immune health.

A Functional Medicine Perspective on Immune Support

Immune function is not binary—it is a coordinated, regulated system. Effective recovery from viral illness depends on:

Adequate micronutrient availability for immune cell signaling
Balanced inflammatory response
Respiratory support when airway reactivity is present
Sufficient hydration, energy availability, and stress regulation

Functional medicine focuses on supporting these systems together, rather than targeting symptoms in isolation.

Walk-In Immune Support at hhc+

Patients may walk in for drips, injections, and nebulized therapies when clinically appropriate. No membership is required for these services.

IV Nutrient Therapy: Hydration and Recovery Support

IV therapy allows for rapid hydration and delivery of targeted nutrients used to support the body during acute illness and recovery.

The Antivirus — Our Signature Immune Drip

The Antivirus is our signature immune-support infusion designed for times of increased viral stress. It is commonly used early in illness or when symptoms are emerging.

This drip includes:

Vitamin C – supports immune cell function and antioxidant defense; evidence suggests modest reductions in symptom duration when used during illness
Zinc – plays a critical role in immune signaling and antiviral defense at the cellular level
L-Lysine – an essential amino acid involved in immune function and protein synthesis, often used during periods of viral stress
B-Complex Vitamins – support energy metabolism and recovery during increased physiologic demand

The Antivirus is intended as supportive immune care, not a stand-alone antiviral treatment, and may be layered with additional therapies based on individual needs.

Additional IV Support (Available as Add-Ons or Stand-Alone Infusions)

In addition to our signature drips, we offer targeted IV nutrients that can be used on their own or layered into your infusion to better match how you’re feeling and what your body needs at the moment.

Glutathione (IV)
Glutathione is the body’s primary intracellular antioxidant and plays a key role in managing oxidative stress during immune activation. IV glutathione is commonly used to support recovery, reduce inflammatory burden, and help patients feel clearer and more resilient during or after illness.

Vitamin C
Vitamin C supports immune cell function and antioxidant defenses during periods of increased physiologic demand. When used during illness, it is often included to support recovery and may help shorten the duration and intensity of symptoms.

B-Complex Vitamins
B vitamins are essential for cellular energy production and nervous system function. During viral illness, metabolic demand increases while appetite and intake often decrease. IV B vitamins are frequently used to support energy, stamina, and overall resilience during recovery.

Magnesium and Fluids
Hydration and electrolyte balance are foundational to recovery. Magnesium supports neuromuscular function and stress regulation and may help ease headaches, body aches, and tension that often accompany viral illness.

These nutrients are commonly combined or added to drips like The Antivirus to create a more personalized, restorative experience—supporting your body while it does the work of healing. Many patients notice they recover more quickly and feel more supported when IV therapy is used early rather than waiting until symptoms fully escalate.

Targeted Injections

Injections are often used as stand-alone support or as add-ons to IV therapy, depending on symptoms and goals.

Common options include:

Vitamin B12
Supports energy metabolism and neurologic function and may be helpful when fatigue is prominent or oral intake has been poor.

Vitamin D
Vitamin D plays a regulatory role in innate and adaptive immune function. High-quality meta-analyses demonstrate that vitamin D supplementation can reduce the risk of acute respiratory infections overall, with the strongest clinical rationale being the correction of deficiency or insufficiency. Optimizing vitamin D status is considered a foundational component of immune health.

Nebulized Therapy: Respiratory-Focused Support

Nebulized therapies deliver medication directly to the airways and are used selectively based on symptom profile.

Nebulized Albuterol (Prescription)
Albuterol is a short-acting bronchodilator with strong evidence and long-standing clinical use. It relaxes bronchial smooth muscle and improves airflow in patients with bronchospasm.

This can be particularly helpful for individuals experiencing:

Chest tightness or wheeze
Viral-triggered airway reactivity
Asthma or reactive airway disease
Cough driven by airway constriction rather than post-nasal drip

Albuterol provides symptom-directed respiratory support and is used when airway reactivity contributes to breathing discomfort. It is not an antiviral therapy.

Nebulized Glutathione
Glutathione is a primary endogenous antioxidant involved in managing oxidative stress within the respiratory tract. In integrative and functional medicine settings, nebulized glutathione is sometimes used to support airway inflammation and oxidative burden during or after viral respiratory illness.

This therapy is used selectively and based on individual tolerance, respiratory history, and clinical presentation. It may be considered in patients with persistent respiratory irritation or prolonged recovery rather than as a routine first-line intervention.

What We Are Intentional About

At hhc+, we are careful not to overstate immune interventions. Nutrients and IV therapy are not cures for viral illness. They are tools used to:

Support hydration and physiologic recovery
Reduce metabolic and oxidative stress during illness
Address common deficiencies that can impair immune response

When symptoms suggest a more serious illness or complications, appropriate medical evaluation and prescription treatment are essential.

Walk-In Support vs Membership-Based Care

Walk-in support may be appropriate if you:

Are early in a viral illness
Feel depleted or run down
Want hydration or recovery support
Have mild to moderate respiratory symptoms

Membership-based care may be a better fit if you:

Get sick frequently
Take longer than expected to recover
Experience post-viral fatigue or lingering symptoms
Have autoimmune, inflammatory, or metabolic conditions
Want a proactive immune strategy rather than reactive care

Membership allows providers to evaluate immune patterns more deeply, prescribe targeted therapies when appropriate, and create a personalized plan for long-term immune resilience.

Our Approach

Immune health is not about doing more—it is about doing what is appropriate, evidence-informed, and individualized.

Flu season does not have to derail your health, but it does require the right level of support.

Ready to Get Support?

Walk in for drips, injections, or nebulized therapy when symptoms arise, or schedule a consult to explore membership-based care if you’re ready to build long-term immune resilience.
