What to expect during your first NAD+ IV session: Duration, comfort, and aftercare

You Booked NAD+ and Now You Have Questions

You read about NAD+ IV therapy, liked what the science showed, and scheduled your first session. Then the questions started. How long does this take? Will it hurt? Can I work during the infusion? Should I eat beforehand? The internet provides contradictory answers because NAD+ sessions vary based on dosage, drip rate, and individual tolerance.

This guide covers every phase of the experience based on what nurses observe during hundreds of NAD+ infusions across Los Angeles, from the booking call to the 48 hours after your session ends.

Before Your Session: Preparation That Makes a Difference

Eat a real meal 60 to 90 minutes before

NAD+ on an empty stomach increases the likelihood and intensity of side effects, particularly nausea and chest tightness. A balanced meal with protein, fat, and complex carbohydrates gives your body fuel to process the infusion. A bowl of oatmeal with almond butter and banana. A chicken wrap from your favorite spot in Studio City. Something substantial, not a granola bar.

Hydrate the morning of

Drink 16 to 24 ounces of water in the two hours before your session. Dehydrated veins are harder to access and more prone to irritation. If you ran a morning workout in Runyon Canyon or spent the morning in dry Santa Monica heat, add electrolytes to that water.

Block your calendar

An NAD+ session (500mg or 1000mg) takes 2 to 4 hours depending on your tolerance and drip rate. Do not schedule the session between meetings or before a dinner reservation. You want the freedom to slow the drip rate if side effects arise without feeling rushed.

Set up your space

The nurse comes to you, so choose where you’ll be comfortable for 2 to 4 hours. A couch with good lighting. A recliner. Your bed propped up with pillows. Have your phone charger, a book, or a laptop within reach. Many clients in Beverly Hills and Brentwood set up in their living room and work through part of the session.

The First 15 Minutes: IV Start and Initial Drip

Your nurse arrives, reviews your health history and current medications, checks your vital signs (blood pressure, heart rate, oxygen saturation), and selects a vein. Most NAD+ IVs go into the forearm or the back of the hand. The needle insertion feels like a quick pinch, nothing worse than a standard blood draw.

The nurse starts the drip at a slow rate. During the first 15 minutes, the NAD+ enters your bloodstream gradually. Most people feel nothing during this phase. Some report a mild warmth spreading through the chest and abdomen. This warmth is normal. It means the NAD+ is reaching your cells and your body is beginning to process it.

The nurse monitors you during this phase and adjusts the drip rate based on how you respond. If you feel comfortable, the rate stays steady. If you notice nausea, chest pressure, or abdominal cramping, the nurse slows the drip. These side effects are dose-dependent and rate-dependent, meaning they respond to adjustments within minutes.

Minutes 15 to 60: The Adjustment Phase

This is when your body negotiates with the NAD+ molecule. As the concentration builds in your bloodstream, you may experience one or more of these sensations:

Chest tightness or pressure. Not pain, more like someone placed a warm hand on your sternum. This is the most commonly reported sensation. It’s caused by the NAD+ activating cellular pathways and is not a cardiac event. If it becomes uncomfortable, the nurse slows the drip and it resolves within 2 to 3 minutes.

Abdominal warmth or mild cramping. The GI tract has high metabolic activity and responds to NAD+ early. Some clients describe it as a gentle warming sensation in the stomach area. Eating beforehand reduces this effect.

Nausea. Usually mild, usually in clients who didn’t eat before the session or who are receiving NAD+ for the first time. The nurse can add anti-nausea medication to the IV line if needed, and slowing the drip rate resolves mild nausea within minutes.

Head pressure or foggy feeling. Some clients report a sense of mental cloudiness during the infusion that clears 30 to 60 minutes after the session. This is more common at the higher dose (1000mg).

None of these side effects are dangerous. They’re all managed by adjusting the drip rate. In the hundreds of NAD+ sessions administered by Instadrip nurses across West Hollywood, Santa Monica, and the broader Los Angeles area, the pattern is consistent: initial side effects during the adjustment phase, gradual tolerance as the session progresses, and no lingering effects after the IV is removed.

Hours 1 to 4: The Steady State

Once your body acclimates, the remaining infusion time feels uneventful. The drip runs. You read, work on your laptop, watch something on your phone, or nap. Some clients take calls. Others meditate. The nurse checks in every 20 to 30 minutes to monitor vitals and assess the drip rate.

By the halfway point of the session, most first-time clients report that the initial chest pressure and warmth have faded. The drip rate may increase slightly if you’re tolerating the infusion well, which shortens the remaining time.

The length of your session depends on two factors:

• Dosage: Instadrip offers 500mg and 1000mg sessions, and both take two to four hours. First-time clients start at 500mg.
• Your tolerance: If the nurse needs to slow the drip rate for comfort, the session extends. Your first session may take longer than subsequent sessions because your body hasn’t encountered this NAD+ concentration before.

The NAD+ add-on at Instadrip comes in 100mg, 250mg and 500mg doses. A standalone NAD+ IV session costs $699 for 500mg, or $1,200 for 1000mg. Your nurse helps determine the right starting dose based on your goals and health history.

Immediately After: The First 2 Hours Post-Session

The nurse removes the IV catheter, applies a bandage, and does a final vitals check. How people feel afterward varies, and we don’t promise a particular effect. For one client’s account, see this West Hollywood story.

Appetite return. If nausea suppressed your appetite during the session, it typically returns within an hour of completion. Eat a balanced meal.

Drink at least 32 ounces of water in the 4 hours after your session. Avoid alcohol for 24 hours. Light exercise is fine. Avoid intense workouts for 12 hours.

After Your First Session

Some clients book a single session, during a demanding week or after travel. Others book a series: a loading phase of 3 to 4 sessions over 2 weeks, followed by monthly sessions. Athletes and active clients often book around training blocks. Our guide to the research covers what has and hasn’t been studied.

Who Books NAD+ IV Sessions in Los Angeles

These clients book NAD+ sessions most often:

Professionals over 40, often after noticing afternoon energy crashes or slower recovery. NAD+ levels decline with age.

Executives and creatives in Beverly Hills and Century City, often ahead of high-stakes presentations, negotiations, or creative deadlines.

Athletes and fitness enthusiasts in Santa Monica and the Westside who train 5 or more days per week.

People coming off a period of poor sleep or heavy drinking. Alcohol and sleep deprivation both accelerate NAD+ depletion.

Frequently Asked Questions About NAD+ IV Sessions

How long does a NAD+ IV session take?

NAD+ sessions (500mg or 1000mg) take two to four hours. First sessions tend to run toward the longer end because the nurse starts with a conservative drip rate.

Does NAD+ IV therapy hurt?

The needle insertion feels like a standard blood draw. During the infusion, some clients experience warmth, mild chest pressure, or abdominal sensations. These are managed by adjusting the drip rate and resolve within minutes.

How much does NAD+ IV therapy cost in Los Angeles?

Instadrip’s standalone NAD+ IV session costs $699 for 500mg or $1,200 for 1000mg, and includes the infusion and a licensed RN. NAD+ can also be added to other IV treatments at 100mg, 250mg or 500mg doses.

Can I work during a NAD+ IV session?

Many clients work on their laptops or take calls during the steady-state phase (after the first 30 to 60 minutes). During the initial adjustment phase, focus on relaxing and communicating with your nurse about how you feel.

How often should I get NAD+ IV therapy?

Some clients book a loading phase of 3 to 4 weekly sessions followed by monthly sessions. Others book a single session.

What should I eat before a NAD+ IV session?

A balanced meal with protein, healthy fat, and complex carbohydrates 60 to 90 minutes before the session. Avoid fasting, as an empty stomach increases the likelihood and intensity of side effects.

Are there side effects from NAD+ IV therapy?

Chest warmth, mild nausea, and abdominal pressure are common during the infusion and managed by adjusting the drip rate. These effects stop when the drip slows and do not persist after the session. No long-term side effects have been documented in clinical use.

Is NAD+ IV therapy safe?

NAD+ is a naturally occurring molecule in every cell of your body. IV supplementation delivers it in concentrations above what oral supplements can achieve. All Instadrip sessions are administered by licensed registered nurses who monitor your vitals throughout the infusion.
