How Long Does IV Therapy Last?

Have you ever wondered, “How long does IV therapy last?” A lot of people ask us this question. The quick answer is that IV fluids usually stay in your body for a few hours. But it’s a bit more complicated than that. IV solutions often have vitamins, minerals, and medicines that can stick around in your body for a while. It’s important to know that the effects of an IV treatment might last longer than the IV fluids themselves. Let’s take a closer look at how long IV fluid lasts.

What Are IV Fluids Exactly?

So, what’s inside an IV fluid bag? The main thing is saline fluid. It’s a mix of water and salt. Saline is like the delivery person for getting vitamins, minerals, and medicines into your bloodstream. But here’s the cool part: saline does more than just deliver stuff.

Saline works wonders at quickly hydrating your body. It’s like a superhero for balancing things out. Electrolytes in the salt can help restore balance in your body. Electrolytes do a bunch of important jobs, like keeping your body’s pH in check, helping nutrients get into your cells, and getting rid of waste from your cells. Plus, these electrolytes keep your heart, brain, nerves, and muscles healthy.

How Long Does IV Therapy Last

Why Hydration Matters

How long will IV saline remain in your body? Your hydration is the main factor. Your body will hold onto the saline solution for longer if you are dehydrated. If you’re already hydrated at the time of your IV treatment, you may start to eliminate the saline over the following hours, mainly through urination.

It’s crucial to examine the different ways that people can dehydrate. This is primarily caused by:

  • Drinking too little water
  • Perspiration
  • Illness
  • Diuretics

Take a closer look at these factors.

Not Drinking Enough Water

Dehydration is not a result of being in a hot desert with emptied canteens. Many Americans are in a constant state of mild dehydration. In one study, 17% to 28 % of older adults were found to be regularly dehydrated. Dehydration is the leading cause of hospitalization in the United States. Dehydration may worsen other medical conditions, or increase the risk of death.

Dehydration symptoms include

  • Thirst
  • Dizziness
  • Confusion
  • Headaches
  • Dark-colored urine
  • Little need to urinate


People in St. Petersburg, Florida love staying active, whether it’s hiking, biking, climbing, running, or other fun stuff. But all that action can make you sweat a lot. Even simple things like walking your dog in the heat or doing a bit of yard work can make you sweat more than you realize.

Studies say the average person can sweat up to 3 liters a day – that’s more than 12.5 cups! When you’re exercising, you might lose anywhere from 0.5 to 2 liters per hour. So, it’s super important to stay hydrated all day long. Make sure to carry water with you, even during winter sports like skiing, snowboarding, or ice skating. You might not feel it, but you can still sweat in the cold!


You can get sick at any time, even if you are drinking enough water each day to stay hydrated. Dehydration can be caused by vomiting and diarrhea.

Dehydration can be caused by:

  • The flu
  • Food poisoning
  • Drinking too much alcohol
  • Hangovers

When you can’t keep enough water in your body, IV therapy is a great way to quickly rehydrate you.


Some foods, drinks, and medications act as diuretics. This increases the amount of fluid your body excretes. Caffeine is one of the main diuretics. Fruits and vegetables are also natural diuretics. Some medications may cause you to urinate frequently.

You may need to consume more water than recommended if you are a heavy drinker of caffeine or if you take diuretic medication.

Your Basal Metabolic Rate

So, how long do IV fluids stick around in your body? The final big thing to think about is your basal metabolic rate (BMR). This is how many calories your body uses up when it’s just chilling. People with higher BMRs burn more calories at rest, and they also process and get rid of liquids faster. If you’re an athlete, your BMR is higher than someone who isn’t active, so IV fluids won’t hang around in your body for as long. It’s like athletes have a quicker exit for liquids compared to those who aren’t as active.

BMR is affected by several other factors.

  • Age
  • Gender
  • Genetic factors
  • Certain medications

What Factors Affect Fluid Retention?

Any fluids you get from an IV drip typically stick around in your system for about two hours. If you’re well-hydrated and haven’t peed in a while, you can clear them out faster.

IV fluids usually don’t hang out in your body for more than a few hours.

Now, when it comes to the good stuff like vitamins and minerals from an IV2ME IV infusion, those stick with you for several days, weeks, or even months. It depends on what your body needs and the type of infusion you go for.

Fluids are like messengers that carry nutrients to all the cells in your body. Your cells won’t work right if you don’t drink enough water. You might feel queasy, have trouble concentrating, or get tired. So, keeping those fluids flowing is key to feeling good!

Difference Between Absorbing Fluids From IV vs. Drinking

You may not be able to retain or pass IV liquids the same way you would if you drank a glass or other beverage.

  • Water and other nutrients can be delivered directly into your bloodstream. The nutrients will be more readily available to your cells.
  • Do not force water through your digestive system to your bladder. This will cause you to lose vitamins and minerals.

Drinking a glass or supplementary drink of water, on the other hand, means that water must pass through your intestines at a relatively constant rate. You cannot “slow down”, how quickly your body moves water after swallowing.

Your digestive system may also compromise or eliminate supplemental beverages or nutrients from drinks that you swallow. This is another reason why IV drip infusions ensure maximum bioavailability and wellness.

The acid in your stomach cannot destroy the nutrients in IV drip infusions. You’ll also see results from an IV drip infusion faster than from a supplement.

How Often Do You Need IV Fluids?

Experts suggest that adults of average weight and size should drink between four and six cups of water each day. Some medical experts argue that this recommendation is too low, as many people still struggle with ongoing dehydration.

At IV2ME, you can schedule a quick mobile appointment for IVs to enhance your vitamin and hydration levels. Most clients typically don’t need IV drips more frequently than once a week because each infusion is a unique mix of vitamins and nutrients. The IV fluids you receive can give your natural hydration a good boost, and you might not need to drink additional water for several hours after your appointment.

Depending on what you choose to infuse, you might not need a second appointment for a few days or even weeks. It all depends on what works best for you!

Final Thoughts – How Long Does IV Therapy Last?

You’ve learned that IV fluids stay in your body for just a few hours, but the good stuff they do doesn’t end there.

Even though IV fluids don’t stick around forever, getting IV drip infusions is still really beneficial. They give your body nutrients and vitamins that can be useful for weeks, months, and even years.

At IV2ME, you can try IV drip therapy for different things like recovering from a hangover or improving your gut health. Check out IV2ME in St Petersburg and Tampa, Florida!
