Side Effects of Hormone Pellets in Men and Women by Dr. Brandon Richland, MD

Hormone pellets are a popular choice for people looking for long-term relief from symptoms related to hormone imbalance. These tiny implants slowly release bioidentical hormones into the body, making them a convenient option for both men and women. Some people may experience side effects from hormone pellets, such as changes in mood, skin issues, or unusual bleeding, so it’s important to know what to expect before starting treatment.

Understanding how hormone pellets work and what side effects may occur can help individuals make informed choices about their health. While most people find the therapy helpful, both men and women can react differently to hormone replacement therapy, and some may need extra monitoring.

Key Takeaways of Side Effects of Hormone Pellets in Men and Women

  • Hormone pellets deliver steady hormone levels over time, helping manage symptoms of menopause, low testosterone, and other hormonal imbalances.
  • Common hormone therapy side effects include mood swings, acne, weight gain, and skin irritation, with more serious risks like blood clots or heart disease possible in certain individuals.
  • Women may experience menstrual changes and breast tenderness, while men may notice increased body hair, oily skin, or changes in libido.
  • Regular blood tests and provider check-ins are crucial for adjusting hormone levels and preventing complications.
  • Hormone pellet therapy is not suitable for everyone, those with hormone-sensitive cancers, or cardiovascular risks, should avoid this treatment.

What Are Hormone Pellets?

Hormone pellets are tiny implants that release hormones into the body over time. These pellets can help people manage symptoms caused by hormone imbalances by giving a steady amount of hormones.

Types of Hormones Used in Pellets

Hormone pellets are most often made from bioidentical hormones, which are designed to mimic the body’s natural hormones. The most common hormones used include testosterone, estradiol, and sometimes progesterone or dehydroepiandrosterone (DHEA). Some pellets are made for women, others for men, and some may use a combined hormone therapy approach for specific needs.

  • Testosterone pellets are usually placed under the skin for men who have low levels and symptoms like low energy or low sex drive.
  • Estradiol pellets are most often used for women experiencing menopause symptoms.
  • Some doctors may use other hormones if a person has special needs, but testosterone and estradiol are the most common.

These pellets are placed under the skin, often near the hip, where they slowly dissolve and deliver hormones directly into the bloodstream. This process allows for better hormone balance with fewer “ups and downs” compared to pills.

Common Side Effects of Hormone Pellets in Men and Women

Hormone pellets can cause a range of side effects in both men and women. These effects may include changes in mood, weight, and skin, and often stem from hormone fluctuations or an imbalance in levels.

Irritability and Mood Swings

Many people using hormone pellets notice mood changes early in treatment. They may feel more irritable, anxious, or have mood swings. This is often due to the body adjusting to new hormone levels, which can cause temporary feelings of restlessness or frustration.

Mood swings might feel like unpredictable shifts between happiness and anger. Some report increased sensitivity or sadness. Hormone fluctuations, especially with high doses from pellets, are a major reason for these emotional shifts.

Sometimes these feelings go away as the body adapts. Other times, they may continue, especially if hormone levels are not well monitored. For some, these changes can be hard to manage and may affect their relationships or work.

Weight Gain and Fluid Retention

Weight gain is another common complaint with hormone pellet therapy. Both men and women can experience increases in body weight, usually from a mix of fat storage and water retention.

Common reasons include:

  • Changes in metabolism
  • Increased appetite
  • Hormone imbalance

Some people notice swelling in their ankles, fingers, or face. This happens because hormone pellets can change how the body holds onto salt and water, leading to bloating.

Weight gain and fluid retention may be mild for some, but others find it uncomfortable and frustrating. If left unchecked, these side effects can impact confidence and daily life. Monitoring hormone levels and making small changes to diet and exercise may help reduce these symptoms. High hormone doses in pellets are often linked with more noticeable weight changes.

Skin Reactions and Acne

Skin side effects are also reported by many people after starting hormone pellets. Acne is one of the most frequent issues, especially in those who never had it before.

Hormonal imbalance or high levels of certain hormones, like testosterone or estrogen, can make acne and other skin problems worse. Most breakouts appear on the face, chest, or back. Sometimes, skin reactions are mild and go away with regular cleaning. For others, breakouts can be severe and require medical attention.

Poor hormone treatment monitoring or an incorrect dose is often the cause. Skin irritation, though less common, can happen near the pellet site and might include pain, redness, or swelling. Regular check-ups can help prevent or treat these skin side effects early.

Side Effects of Hormone Pellet Therapy in Men

Hormone pellets containing testosterone are often used to treat low testosterone and hormone imbalances in men. Many men notice changes in their bodies and how they feel, especially as testosterone levels rise after treatment.

Increased Hair Growth and Scalp Changes

Men using testosterone pellets can experience increased hair growth. This hair growth often appears on the face, chest, arms, and back.

Some men notice that their facial hair becomes thicker and grows faster after their pellet therapy begins. At the same time, changes to the scalp can happen. Hair thinning or male pattern baldness can appear or get worse for men who already have a family history of hair loss.

While not every man will see these changes, it is common enough that doctors may ask about hair pattern shifts during checkups. A few men may see only mild changes, while others get more noticeable effects.

Testosterone-Related Effects

Testosterone pellets boost testosterone levels in the body, sometimes causing mood swings, increased energy, or changes in sex drive. Many men see an improved libido and higher energy, which can help with symptoms of andropause.

Acne or oily skin may develop as a result of higher testosterone. Some men may also notice a rise in red blood cell count, which their health provider may want to monitor.

Sleep problems can also appear, such as trouble staying asleep. A small number of men experience breast tenderness or breast tissue growth.

The risk of these testosterone side effects depends on the individual and the dosing. Regular lab tests are helpful for tracking possible changes and making pellet therapy safer.

Side Effects of Hormone Pellet Therapy in Women

Hormone pellets can affect women in unique ways, especially when it comes to breast and menstrual health. Changes may occur due to shifts in hormones like estrogen and testosterone, and can be more noticeable during menopause or perimenopause.

Breast Tenderness and Changes

Women receiving hormone pellet therapy can experience breast tenderness, swelling, or discomfort. This often happens when hormonal levels, especially estrogen and estradiol, increase or shift more than the body is used to.

Some may notice that their breasts become more sensitive to touch, fuller, or even slightly painful. These symptoms can resemble what some women feel before a menstrual period. In rare cases, there may be a small increase in breast size. These changes are usually mild and can fade as the body adjusts.

Menstrual Changes and Vaginal Symptoms

Hormone therapy can lead to changes in the menstrual cycle. Some women may have irregular periods, spotting, or even a complete stop of menstruation. These effects are more common in women near menopause or those already going through perimenopause.

Other possible symptoms include vaginal dryness, irritation, or itching. These are linked to changes in both testosterone and estrogen levels. Hormonal imbalances can also cause or worsen hot flashes and night sweats.

Some women notice improvements in menopausal symptoms such as mood swings or decreased libido, but side effects like vaginal issues may still happen.

Serious Risks and Rare Adverse Reactions

Hormone pellets can sometimes cause problems that are uncommon but can be very serious. These risks may affect major organs or cause life-threatening issues for both men and women.

Infection and Allergic Reactions

After pellet insertion, infections can develop at the site under the skin. Signs include pain, redness, swelling, drainage, or fever. Good skin care and clean procedures help lower this risk but do not remove it completely. Some people react badly to the pellet materials or preservatives. Symptoms of allergic reactions include rash, itching, swelling, or even trouble breathing, which need fast medical help.

Serious infection or allergic reactions can need antibiotics or removing the pellets. Anyone with a past history of allergies should tell their doctor before starting treatment. These side effects are not common, but they can be dangerous and need close attention.

Blood Clots, Stroke, and Heart Disease

Hormone pellets can increase the risk of blood clots in some patients. Blood clots can cause pain, swelling, or redness in the leg, and can move to the lungs, which is a medical emergency.

Testosterone and estrogen from pellets may also raise the risk of major problems like stroke, heart attack, and other types of heart disease, especially in people with other risk factors like high blood pressure or diabetes. Risk is higher in those who are older or already have heart disease.

People who use hormone therapy and have a history of blood clots, stroke, or heart disease should talk with their doctor and watch for warning signs. In rare cases, hormone pellets may also affect the liver or increase the risk for cancers like prostate, breast, or uterine cancer, so regular check-ups are important for early detection.

Long-Term Safety and Monitoring

Hormone pellet therapy is used to help manage symptoms from hormonal changes, but monitoring and regular testing are needed. Hormone levels can change over time, and working with a healthcare provider is key to keeping hormone balance and avoiding unwanted effects.

Hormone Imbalance and Overdose Risk

Incorrect hormone levels can cause problems like headaches, weight gain, or fatigue. The risk of imbalance or overdose is higher if the pellets are not tailored to each person’s needs. Because the pellets are long-lasting, it takes time to adjust the hormone dose if symptoms occur. This makes it important to follow a personalized treatment plan and pay attention to symptoms between visits. Hormone pellet therapy is not yet FDA-approved, so careful monitoring is important to catch problems early.

Common Signs of Imbalance:

  • Irregular periods (in women)
  • Mood changes
  • Unusual hair growth
  • Unexplained weight gain
  • Oily skin or acne

Regular Hormone Testing and Evaluation

Regular hormone testing helps track how the body is reacting to the pellets. Stable hormone levels can lower the chance of side effects. Blood tests check if hormone levels are in a safe range. Most healthcare providers recommend testing before and after pellet insertion, as well as during treatment.

Doctors use these test results to change the dose if needed. Patients who skip follow-up visits or testing are more likely to have problems. Some side effects may take several months to develop, so ongoing monitoring is important to keep hormone levels stable and ensure the treatment is working well.

Who Should Avoid Hormone Replacement Therapy?

Certain people should not use hormone pellet therapy due to medical risks or drug interactions that may cause harm. It is important to check your medical history and talk with a health professional before choosing this treatment.

Pre-Existing Conditions and Contraindications

People with hormone-sensitive cancers, such as breast, uterine, or prostate cancer, should avoid hormone pellet therapy. Pellets release hormones like estrogen or testosterone, which can make these cancers worse. Anyone with a history of blood clots, stroke, or heart disease also faces higher risks of complications from hormone therapy.

Hormone pellet therapy is not always safe for women who are pregnant or breastfeeding. Certain liver problems, like active liver disease or liver tumors, can be made worse by these treatments, especially in those using compounded hormones or bioidentical hormone replacement therapy. People with untreated endometrial hyperplasia or undiagnosed vaginal bleeding should avoid this therapy, as more hormones may increase health risks.

Potential Drug Interactions

Some medications can change how the body breaks down hormones, leading to problems with hormone pellet therapy. For example, medicines for seizures (like phenytoin or carbamazepine), some antibiotics, and certain antifungals can lower or raise hormone levels in the blood. As a result, symptoms may get worse, or side effects may become more likely.

Common drugs that might interact include blood thinners like warfarin, medicines for diabetes, and treatments for depression. If someone is using other forms of hormone therapy, such as compounded hormones or BHRT, a doctor should always review all medications. This helps prevent unwanted side effects, hormone imbalances, or changes in how either drug works.
