What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.


Vitamin B12 shots (cyanocobalamin) are injections designed to supply important vitamin supplements and vitamin absorption for people that struggle to absorb enough B12 through their daily diet. It’s important because vitamin B12 is integral for many functions, including optimized cell reproduction, blood formation, protein, and tissue synthesis. It is a key supplement for people suffering from pernicious anemia, and for vegetarians and vegans that have vitamin B12 deficiencies related to dietary choices. Some benefits can include red blood cell formation and nerve cell health. You can buy vitamin B12 injections online from a pharmacy and administer the injection for yourself if you know how to do it safely.


Most vitamin B12 injection are injected into the fatty tissue just beneath the skin. When you buy Vitamin B12 injections online (with prescription) the pharmacy will provide you with printed instructions laying out how to administer the injection for yourself. However, you should never give yourself a B12 injection unless you are completely confident in how to do it. If you aren’t completely confident in your ability or feel worried, a safe choice may be to schedule an appointment to have it administered by a physician in their clinic, or to have your B12 shot administered at a pharmacy. 

The standard vitamin B12 injection dosage for adults is 6 mcg (micrograms) per day.

B12 shots are administered either intramuscularly (into the muscle) or subcutaneously (just under the skin). The 3 body regions where a person can receive a vitamin B12 injection intramuscularly are the thigh, buttocks, or arms. The thigh is best and most advisable for anyone who is self-administering a B12 shot. Subcutaneous B12 injections are a better choice when possible, and the front of the thigh is also best for this method. Lower abdomen or side or back of upper arm are locations it can be administered into too.

Ensure the area is clean and sanitized before injecting. Once your skin sterile and dried, you must then use your index finger and thumb pull the skin taut (tight) over the region to then administer the B12 shot. The skin of the injection site should be smooth, and if you are injecting intramuscularly then it’s important that the muscle is relaxed.


The active ingredient in Vitamin B12 injections is cyanocobalamin.


It is inadvisable to give yourself an injection of any sort unless you are fully confident in your ability to inject the drug or supplement safely, and this applies to a B12 injection too. Vitamin B12 injections are considered very safe, but this precaution must still be followed and without exception. Individuals who are prone to fainting or otherwise feeling discomfort around a needle should seek help from a medical professional to administer the vitamin B12 dosages safely.

Any persons experiencing adverse vitamin B12 injection side effect reactions - most notably pain or any visible skin reaction at the injection spot - discontinue use and speak to your doctor.


Vitamin B12 injections are known to be safe, and there being no documented risks of drug or supplement interaction them is a part of that. If you wish further clarification on this, you should speak with the pharmacist at the pharmacy where you buy your vitamin B12 injections online. Alternately, you can speak to a pharmacist at your local pharmacy before ordering a B12 shot online.

Side Effects

It is uncommon to experience vitamin B12 injection side effects, but some people may have an allergic skin reaction. If this occurs to you then discontinue use and speak to your doctor or pharmacist. B12 can also be taken as a sublingual tablet, and that may be a better choice for anyone who would rather not inject themself or purchase vitamin B12 without a prescription.
