IV vitamin therapy and IV hydration in San Antonio
Short answer: IV therapy sends fluids, and sometimes vitamins and minerals, straight into a vein. At Yaso Wellness, on San Antonio's South Side, IV infusions are given in the clinic after a health screening. IV fluids can help with hydration. For people without a deficiency, most other claimed benefits of vitamin drips are not proven, and IVs carry real risks.
Key facts
- What it is: a small, thin tube (catheter) is placed in a vein, usually in the arm, and a bag of fluid drips in over a set time. Many sessions last about 30 to 60 minutes.
- What is proven: IV fluids treat dehydration. Single vitamins given by injection or IV treat specific, diagnosed deficiencies.
- What is not proven: Merck's MSD Manual reports that very few studies have tested high-dose IV vitamin mixes in people without a deficiency, and the claimed effects on energy, immunity and mood have not been confirmed.
- Risks: bruising, pain or swelling at the site, vein irritation, infection, fluid overload, and mineral imbalances that can affect heart rhythm.
- Texas law: since September 1, 2025, Texas law (Occupations Code chapter 172) limits who may give elective IV therapy outside a physician's office or licensed facility to a physician, PA, APRN or RN, under a physician's supervision.
What is IV vitamin therapy, and how is it different from IV hydration?
IV hydration is a bag of sterile fluid with salts (electrolytes), such as saline. It replaces water and salts the body has lost. It is the same basic fluid used in hospitals.
IV vitamin therapy adds nutrients to the fluid. A common mix, often called a Myers' cocktail, contains B vitamins, vitamin C, magnesium and calcium. IV delivery skips digestion, so the vitamins reach the blood directly. Whether that offers any health benefit for people whose vitamin levels are already normal is not well established. Most healthy people get the vitamins they need from food.
Can IV therapy help with dehydration or feeling run down?
Some people seek IV hydration for short-term relief when they are dehydrated, for example after a stomach bug or a long day in the Texas heat. IV fluids can help with hydration. Many people with mild dehydration do just as well drinking water or an oral rehydration drink, which is simpler and carries no needle risks.
If you feel tired all the time, an IV is not the answer to why. Ongoing fatigue can come from anemia, thyroid problems, poor sleep, depression, perimenopause and many other causes. A visit with Dr. Vargas can look for the reason and test for real deficiencies, such as low iron or low vitamin B12.
What are the risks of an IV infusion?
IV therapy is a medical procedure, not a spa treatment. Possible problems include:
- pain, bruising or swelling where the needle goes in;
- fluid leaking into the tissue around the vein;
- vein irritation or inflammation;
- infection, which has caused serious illness and deaths when equipment was not sterile;
- fluid overload in people with heart or kidney problems or high blood pressure;
- low blood pressure, lightheadedness or fainting if fluid runs in too fast;
- abnormal magnesium or potassium levels, which can affect heart rhythm;
- allergic reactions, including rare severe reactions to large doses of thiamine (vitamin B1);
- nerve damage from repeated high doses of vitamin B6.
Some vitamins and minerals can also interact with medicines, such as blood pressure pills and certain antibiotics. Bring a full list of what you take.
Who should not get an IV vitamin drip?
Not everyone is a candidate. Tell the clinic if you:
- are pregnant or breastfeeding;
- have kidney disease, heart disease, heart failure or high blood pressure;
- take water pills (diuretics) or drink alcohol heavily;
- have had a reaction to an IV or vitamin injection before.
What happens at an IV visit at Yaso?
- Screening first. Every IV is ordered by a licensed clinician after a health screening. You'll be asked about your health history, medicines and allergies, and your vital signs are checked.
- A licensed nurse places the IV. IVs are started by a registered nurse or higher, with clean, single-use supplies.
- You're watched during the drip. Staff check on you while the fluid runs. Speak up right away if you feel pain at the site, chest tightness, trouble breathing, a racing heart or dizziness.
- Aftercare. Keep the small bandage on for a short time. Call the clinic if the site gets red, hot, swollen or painful, or if you get a fever.
The clinic is at 1907 Goliad Rd on San Antonio's South Side, and care is led by Leticia Vargas, MD.
What to ask your clinician
- Do I have a real deficiency, and how would we know?
- What exactly is in this bag, and why each ingredient?
- Is anything in it a problem with my medicines or health conditions?
- Would drinking fluids or a pill work just as well for me?
- Who will place my IV, and what are their credentials?
- What symptoms during or after the drip mean I should get help?
FAQs
How long does an IV infusion take? Most sessions take about 30 to 60 minutes, plus time for the screening.
Are IV vitamins better than pills? IV vitamins skip digestion, but for people without a deficiency there is little proof they improve health. For most people, food and, if needed, an oral supplement are enough.
Does IV therapy boost the immune system or prevent colds? There is no good evidence that IV vitamins prevent colds, flu or other infections.
How often can I get IV therapy? That depends on the reason and your health. More is not better, since high doses of some vitamins and minerals can cause harm. Your clinician will advise you.
