Hormone injections are common treatments for conditions like diabetes, low testosterone, infertility and growth disorders. They can work fast and help when oral pills won't do the job. But injections also carry risks if used wrong. This page helps you understand the most common types, how injections are given, simple safety tips, and when to talk to your doctor.
Insulin is the best known. People with diabetes use subcutaneous insulin to control blood sugar. Testosterone injections treat low testosterone in men and sometimes women; they are usually intramuscular and given every week to month depending on the product. Human chorionic gonadotropin, or hCG, and follicle stimulating hormone are used in fertility treatment. Growth hormone injections help children and adults with certain deficiencies, but they need careful monitoring.
Most home injections are subcutaneous (under the skin) or intramuscular (into a muscle). Nurses or doctors usually teach the first shots. Follow instructions on dose, needle size, injection site and schedule exactly. Don't mix or change doses without medical advice. Store vials and pens as directed — many need refrigeration but some must stay at room temperature. Check expiry dates and never use cloudy or discolored solutions. Dispose of needles in a proper sharps container; don't toss them in regular trash.
Side effects vary by hormone. Common reactions include local pain, redness, mild swelling, and sometimes mood changes or fluid retention. Serious signs like high fever, hard swelling, breathing trouble, severe pain, or signs of infection need urgent care. If your doctor orders blood tests or hormone level checks, keep those appointments. Monitoring keeps doses safe and effective.
Buying hormone medicines online can save money, but be careful. Only use licensed pharmacies, check reviews, and avoid sites that offer prescriptions without a doctor. Keep a list of your medications, doses and injection dates. Share it with any provider who treats you.
Questions to ask your clinician: what side effects to expect, how long you will need injections, and how to handle missed doses. If something feels off, call your healthcare team right away.
Rotate injection sites to prevent lumps and skin damage — use thighs, abdomen, buttocks or upper arms as instructed. Mark your calendar or app so you don't repeat the same spot. Pens are easier for many people and have prefilled doses. Vials and syringes give flexibility but need drawing up. Learn both methods if you might switch products.
Travel tips: keep medicine cool in an insulated bag with a cold pack, carry a doctor's letter for airport security, and store spare needles and a sharps box at your destination.
Pregnancy, breastfeeding and certain heart, liver or cancer histories change whether hormone injections are safe. Always review your full health history before starting.
