B12 Shots in Potranco (Hunt Lane), San Antonio

At Fast Aid Urgent Care, we often evaluate patients who may be experiencing symptoms related to vitamin B12 deficiency, such as fatigue, weakness, numbness, or memory problems. A good candidate for B12 shots is typically someone who is diagnosed with a vitamin B12 deficiency, which our medical team can identify through blood tests and a thorough clinical evaluation.

Certain medical conditions can affect your body’s ability to absorb B12, including pernicious anaemia, atrophic gastritis, celiac disease, and Crohn’s disease. If you have had gastrointestinal surgery, such as a gastric bypass, you may also be at risk. Individuals who follow strict vegetarian or vegan diets may need B12 supplementation, as this essential vitamin is mainly found in animal products. Older adults may also develop B12 deficiency since the ability to absorb B12 often decreases with age. Additionally, people taking specific medications, such as metformin for diabetes or proton pump inhibitors for acid reflux, can also be more susceptible.

At Fast Aid Urgent Care, we recommend B12 shots in these situations because the injections bypass the digestive system, allowing for fast and effective absorption directly into the bloodstream. If you suspect you might be at risk for B12 deficiency, or if you are experiencing related symptoms, our experienced healthcare providers can assess your needs and determine if B12 injections are right for you. It’s important to be evaluated before starting B12 therapy, as unnecessary supplementation is not recommended for individuals with normal B12 levels.

At Fast Aid Urgent Care’s Potranco (Hunt Lane) location in San Antonio, Dr. Curtis Grote, MD, offers vitamin B12 injections following standard, evidence-based medical protocols. Dr. Curtis begins by carefully reviewing your medical history and current symptoms to determine if you may be experiencing a vitamin B12 deficiency or if you could benefit from B12 supplementation.

If a B12 injection is recommended, Dr. Curtis will prepare the appropriate dosage of vitamin B12, typically in the form of cyanocobalamin or hydroxocobalamin. The injection is usually administered intramuscularly—most commonly in the upper arm (deltoid muscle), though the thigh or hip may also be used depending on your individual needs.

The procedure is straightforward and quick. The skin at the injection site is thoroughly cleaned with an antiseptic, and a small needle is used to deliver the vitamin directly into the muscle. Most patients experience only a brief pinch or mild stinging sensation during the injection.

After your B12 shot, our staff will monitor you for a short time to watch for any signs of an allergic reaction or side effects, which are rare. We will also provide you with information on what to expect post-injection and guidance on any potential side effects to watch for once you leave the clinic. Depending on your health needs and how you respond to treatment, follow-up appointments or a series of injections may be scheduled.

At Fast Aid Urgent Care, we understand that when you come to us for a B12 injection, you want to know when you’ll start feeling better. The timeline for experiencing the benefits of a B12 shot can vary from person to person and depends on the reason you’re receiving the injection. Many of our patients report feeling increased energy and reduced fatigue within 24 to 72 hours after their B12 shot.

For patients with more significant B12 deficiencies or underlying health issues, it may take several days or even a few weeks to notice significant improvements. If you’re receiving B12 injections to help with neurological symptoms—such as numbness, tingling, or memory concerns—improvements may take longer and often require ongoing treatments.

Our medical providers will tailor your treatment plan and monitor your progress to ensure the best results. It’s important to follow our recommendations and let us know how you’re feeling after your injection. If you don’t notice an improvement or if your symptoms worsen, please contact Fast Aid Urgent Care for further evaluation. Your health and well-being are our top priorities.

At Fast Aid Urgent Care, we frequently see patients with questions about vitamin B12 shots—whether they need them, and if so, how they can help. Vitamin B12 injections are most commonly recommended for individuals with a diagnosed deficiency. This deficiency can result from dietary restrictions (such as vegetarian or vegan diets), certain medical conditions, or problems with nutrient absorption.

For most people without a diagnosed B12 deficiency, getting a B12 shot is not typically necessary. The body usually stores enough vitamin B12, and any excess is naturally eliminated in urine since B12 is water-soluble. While some people pursue B12 injections hoping for increased energy, improved mood, or better cognitive function, research shows these benefits are generally limited to those who are actually deficient.

Medical guidelines support B12 supplementation for individuals at risk for deficiency—including older adults, people with specific gastrointestinal conditions, strict vegetarians or vegans, and those taking certain medications. At Fast Aid Urgent Care, our healthcare providers can help determine whether you fall into one of these categories and if a B12 shot could benefit your health.

Although B12 injections are considered safe for most people, receiving unnecessary injections can lead to avoidable medical costs and, in rare cases, allergic reactions or injection site discomfort. That’s why, before starting any supplementation, it’s important to consult with a medical professional.
