My physician/practitioner has recommended bioidentical hormone therapy delivered by a pellet inserted under my skin for treatment of symptoms I am experiencing related to low hormone levels. The following information has been explained to me prior to receiving the recommended therapy.
OVERVIEW
Bioidentical hormones are hormones that are biologically identical to that made in my own body. The levels of active estradiol and/or testosterone made by my body have decreased, and therapy using these hormones may have the same or similar effect(s) on my body as my own naturally produced hormones. The pellets are a delivery mechanism for estradiol and/or testosterone, and bioidentical hormone replacement therapy using pellets has been used since the 1930’s. There are other formulations of estradiol and testosterone replacement available, and different methods can be used to deliver the therapy. There are no commercially available forms of testosterone, however, that are formulated specifically for use in women. The risks associated with pellet therapy are generally similar to other forms of replacement therapy using bioidentical hormones.
RISKS/COMPLICATIONS OF PELLET INSERTION:
Risks associated with pellet insertion may include: bleeding from incision site, bruising, fever, infection, pain, swelling, pellet extrusion which may occur several weeks or months after insertion, reaction to local anesthetic and/or preservatives, allergy to adhesives from bandage(s), steri strips or other adhesive agents.
RISKS/COMPLICATIONS OF TESTOSTERONE:
Some individuals may experience one or more of the following complications with testosterone: acne, abnormal bleeding or a change in menstrual cycle (if patient has a uterus), anxiety, breast or nipple tenderness or swelling, insomnia, depression, mood swings, fluid and electrolyte disturbances, headaches, increase in body hair, fluid retention or swelling, mood swings or irritability, rash, redness, itching, lack of effect (typically from lack of absorption), transient increase in cholesterol, nausea, retention of sodium, chloride and/or potassium, weight gain or weight loss, thinning hair or female pattern baldness, hypersexuality overactive libido) or decreased libido, overproduction of estrogen (called aromatization) or an increase in red blood cell formation or blood count erythrocytosis). The latter can be diagnosed with a blood test called a complete blood count (CBC). This test should be done at least annually. Erythrocytosis can be reversed simply by donating blood periodically, but further workup or referral may be required if a more worrisome condition is suspected.
FERTILITY AND TESTOSTERONE:
IMPORTANT: Testosterone may affect the ability to conceive. If you are planning to start or expand your family soon, please talk to your provider about other options.
RISKS/COMPLICATIONS OF ESTRADIOL (ONLY APPLICABLE IF RECEIVING ESTRADIOL IN THE PELLETS)
The side-effects of estradiol are similar to those listed above for testosterone. Additionally, there is some risk, even when using bioidentical hormones, that estrogens may cause existing cases of some breast cancers to grow more rapidly. This risk may also apply to some undiagnosed forms of breast cancer. Using estrogen-alone (without progesterone) may increase the chance of getting cancer of the uterus. Endometrial sampling (biopsy) or surgery may be required if abnormal bleeding occurs.
