How It Works

Frequently Asked Questions

Is IV therapy safe?

IV therapy is generally safe when administered by licensed medical professionals in proper clinical settings. Common minor risks include bruising at the injection site, mild discomfort during infusion, and rarely, allergic reactions to specific ingredients. Serious complications are rare but can include infection, air embolism, and fluid overload in susceptible patients. Always disclose your complete medical history and current medications before treatment.

How long does an IV therapy session take?

Basic hydration drips take 30-45 minutes. Standard vitamin drips (Myers' Cocktail) take 45-60 minutes. High-dose vitamin C takes 60-90 minutes. NAD+ infusions take 2-4 hours due to the need for slow administration. Plan for additional time for intake paperwork and post-infusion monitoring.

Can I get IV therapy if I'm on medications?

Most medications are compatible with IV therapy, but disclosure is essential. Some medications may interact with IV ingredients — for example, blood thinners and high-dose vitamin C, or certain heart medications and IV magnesium. A qualified provider will review your medication list before recommending a drip formulation.

Do I need a doctor's prescription for IV therapy?

Requirements vary by state. Many IV therapy clinics operate under a medical director's standing orders, which means you do not need a personal prescription. However, a medical intake and screening process should be conducted before treatment. Some states require physician orders for specific ingredients or high-dose protocols.

How soon will I feel effects from IV therapy?

Many patients report feeling effects within hours of an infusion — improved energy, mental clarity, and reduced fatigue are commonly noted. Hydration benefits are nearly immediate. Some benefits (immune support, nutrient repletion) develop over multiple sessions. NAD+ infusions may produce noticeable cognitive effects within the session itself.
