Market Analysis



For patients dealing with low testosterone levels or hypogonadism, certain treatments that help in restoring the normal testosterone levels can be beneficial. Testosterone patches and gels are two such treatment options that are prescribed to replenish testosterone. These therapies both aim to restore normal hormone balance but offer different modes of application and absorption rates.

The testosterone patch is a transdermal system designed to slowly release the hormone into your bloodstream through your skin over 24 hours. It's typically applied once daily on specific areas of the body like back, thighs, or upper arms.

On the other hand, Testosterone gel also offers a similar method of delivery but tends to absorb more quickly than patches. It's often applied once daily on clean dry skin usually over shoulders or upper arms.

Both treatments are capable of effectively managing symptoms associated with low testosterone levels such as fatigue, loss of muscle mass and decreased libido; however patient preference regarding ease of use and individual response may determine which option is most suitable for each person.

What is Testosterone Patch?

Testosterone replacement therapy can come in different forms, two of which are the testosterone patch and gel. The testosterone patch was a significant development over previous methods of hormone replacement therapy when it first came to market. It is applied daily to the skin, allowing for a steady release of testosterone into the bloodstream through transdermal absorption. This method bypasses the liver and is less likely to cause liver-related side effects compared to oral therapies. The patches may occasionally cause skin irritation at the application site.

The introduction of testosterone gels offered an alternative form of treatment that some find more convenient than patches. They also provide a continuous supply of hormones throughout the day once they're absorbed through your skin after topical application, similar to patches but with lower instances of skin irritation. However, there's potential for transfer if direct physical contact occurs before it dries or if clothing isn't worn over it immediately after application.

Both treatments serve as effective options depending on individual preferences, lifestyle considerations and how one's body reacts towards each method.

What conditions is Testosterone Patch approved to treat?

Testosterone patches and gel are both approved for the treatment of conditions related to low testosterone levels:

  • Hypogonadism, a condition in which the body doesn't produce enough testosterone
  • Conditions associated with chronic or acute health problems that cause hypogonadism
  • Age-related decline in testosterone production

How does Testosterone Patch help with these illnesses?

A testosterone patch works to manage low testosterone levels by delivering a steady supply of the hormone through the skin and into the bloodstream. It does this via transdermal absorption, allowing it to be gradually released over time. Testosterone is an essential hormone that plays a vital role in maintaining muscle mass, bone density, red blood cell production, sex drive, mood stability amongst other things. Low levels of testosterone can result in symptoms such as fatigue, depression, decreased libido and physical weakness. By providing a consistent amount of testosterone directly into the bloodstream, patches can effectively help patients manage these symptoms and stabilize their hormonal balance.

Similarly yet differently administered is testosterone gel which also serves to replenish low or imbalanced levels of this key hormone in men who are experiencing hypogonadism (underactive testes). The gel is applied daily on clean dry skin often on upper arms or shoulders for optimal absorption. This easy application process makes it convenient for many users while still addressing similar issues caused by lowered testosterone as those addressed by use of patches.

What is Gel?

Testosterone gel, sold under brand names like AndroGel and Testim, is a topical hormone replacement therapy that helps to restore normal testosterone levels in men. It works by being absorbed through the skin directly into the bloodstream to increase the level of testosterone. This method has been approved by the FDA since 2000.

Unlike patches, which can cause skin irritation at the application site or fall off during exercise or sweating, gels are applied and quickly dried onto areas such as upper arms/shoulders which reduces these risks. Gels also enable easier dosage adjustments compared to patches.

Side effects can include potential transfer of medication if direct contact occurs before it dries completely and increased red blood cell counts leading potentially to thickened blood; but on balance they offer an alternative for those who struggle with other forms of treatment such as injections or implants.

What conditions is Gel approved to treat?

Testosterone gel has been approved for the treatment of:

  • Hypogonadism, a condition where the body doesn't produce enough testosterone
  • Certain types of breast cancer in women

It's important to note that despite being applied topically, testosterone gel can have systemic effects and should always be used under medical supervision.

How does Gel help with these illnesses?

Testosterone is a hormone that plays key roles in the body, affecting muscle mass, bone density, red blood cell production and also heavily involved in male sexual development. Low levels of testosterone can lead to symptoms like fatigue, depression, irritability and loss of libido. Testosterone gel works by supplementing or replacing the testosterone naturally produced in the body. It is applied daily on clean dry skin usually on upper arms or abdomen allowing for steady absorption through the skin into your bloodstream over 24 hours providing a constant level of hormone which mimics natural rhythms. This method avoids first-pass metabolism (processing by liver before reaching systemic circulation) as seen with oral medications but still carries some risks such as accidental exposure to others through skin contact and variability in absorption depending on individual factors such as skin condition and application site. In contrast with patches which may cause local irritation and are visually noticeable; gels are less likely to cause discomfort at the application site and once dried are invisible making them more discreet option.

How effective are both Testosterone Patch and Gel?

Both the testosterone patch and gel are approved methods for treating low testosterone levels, a condition which can contribute to decreased energy, mood changes, reduced muscle mass and bone density. They both provide a controlled release of testosterone through the skin into the bloodstream. The effectiveness of these two treatments has been compared in various studies; similar efficacy in managing symptoms associated with low testosterone were noted along with comparable safety profiles.

The choice between a patch or gel may depend on individual patient circumstances and preferences. A 2003 clinical trial conducted by Meikle et al., found that patients using the patch tended to experience more skin irritation than those using the gel. However, some patients prefer patches as they only need to be applied once daily while gels often require twice-daily applications.

A comprehensive review performed in 2015 suggests that both forms have proven effective at increasing serum testosterone levels within normal range starting from first week of treatment. It also stated that side effect profile is generally favorable over other treatments such as injections and oral tablets due to their steady release of hormone throughout the day avoiding peaks and troughs associated with other delivery methods.

Further investigation shows an increase in use of gel formulations owing to their easy application process without causing much disruption on skin unlike patches which might lead to visible marks post removal. Nonetheless, due its unique formulation benefitting those who have problem tolerating adhesives used in transdermal patches or who prefers less frequent dosing schedule, patches continue being widely prescribed second-line option after gels.

At what dose is Testosterone Patch typically prescribed?

For testosterone replacement therapies, the dosage can vary based on individual needs and responses to the treatment. Testosterone patches typically deliver 2-4 mg of hormone per day and are applied once daily. On the other hand, testosterone gels provide a more flexible dosing regimen with initial doses often starting at 5g/day (delivering approximately 5mg of testosterone), but can be adjusted by your healthcare provider according to response. The maximum recommended dose for gel is generally not more than 10g/day. It should be noted that children should never come into contact with areas of skin where these products have been applied in order to prevent accidental exposure.

At what dose is Gel typically prescribed?

Testosterone gel treatment is usually initiated at a dosage of 50 mg/day, applied topically to clean, dry skin on the shoulders or upper arms. Depending on individual patient response and serum testosterone levels, this dose can be adjusted up or down as necessary with most men requiring between 20-100 mg/day. The application site should not be washed for at least two hours after applying the gel and direct contact with others should be avoided until the area has been washed. If there's no satisfactory response in symptoms or blood testosterone levels after several weeks of daily usage at maximum dose (100mg), an alternative form of testosterone therapy may need to be considered.

What are the most common side effects for Testosterone Patch?

Potential side effects of both the testosterone patch and gel can include:

  • Skin irritation at the application site
  • Hair growth or hair loss
  • Acne
  • Dry skin, oiliness
  • Headache, dizziness
  • Increased/decreased sexual desire (libido)
  • Nervousness, anxiety
  • Emotional changes such as depression or aggression
  • Insomnia (trouble sleeping) or increased sleepiness/drowsiness
  • Changes in blood lipid profile (cholesterol levels) -Nausea
    -Bloating due to water retention
    -Sweating more than usual
    -Increased red blood cell count.

Each individual may respond differently to these forms of treatment and it is important to have regular follow-ups with a healthcare provider to monitor for any potential adverse reactions.

Are there any potential serious side effects for Testosterone Patch?

Testosterone patches and gels are both used to treat low testosterone levels in men, but they can have different potential side effects:

  • Increased aggression or changes in mood
  • Signs of an allergic reaction: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
  • Changes in skin color or appearance at the site where applied (redness, blistering)
  • Symptoms of high blood pressure such as headaches, shortness of breath
  • Swollen ankles/feet due to water retention
  • Unusual weight gain
  • Enlarged/prolonged erections If you experience any signs of a heart attack - chest/jaw/left arm pain; confusion; fainting; sudden vision changes or weakness on one side of your body.

These lists are not exhaustive. If you experience other symptoms that may be related to your testosterone treatment and which cause concern, consult with your healthcare provider immediately.

What are the most common side effects for Gel?

Testosterone gel, much like the patch, can come with a variety of potential side effects. Here are some you may experience:

  • Skin irritation where the gel is applied
  • Mood changes or anxiety
  • Increase in acne and hair growth
  • Headache or dizziness
  • Nausea, vomiting and stomach pain
  • Changes in sexual desire
  • Trouble sleeping or insomnia
  • Swelling in ankles or feet due to fluid retention. It's important to monitor your body's reactions when starting this medication as rarely it can cause more serious issues such as chest pain, difficulty breathing or signs of a blood clot. Always consult with your healthcare professional if any adverse effects occur.

Are there any potential serious side effects for Gel?

Testosterone gel, while generally safe for use under medical supervision, may cause some serious side effects in rare cases. These include:

  • Signs of a severe allergic reaction such as hives; difficulty breathing; swelling of your face, lips, tongue or throat
  • Unusual changes in mood or behavior such as agitation, hostility, anxiety or depression
  • Increased urination (especially at night), increased thirst and appetite with weight loss
  • Sudden chest pain or discomfort, wheezing and dry coughing
  • Swelling in ankles and legs along with rapid weight gain
  • Skin reactions including redness, rash itching peeling blisters on the skin where the gel was applied

If you experience any of these symptoms after using testosterone gel it is crucial to seek immediate medical attention. As always consult your healthcare provider before starting any new medication regimen.

Contraindications for Testosterone Patch and Gel?

Both testosterone patches and gels, like all hormone replacement therapies, may cause side effects in some individuals. If you notice any adverse reactions such as breathing difficulties; swelling of your face, lips, tongue or throat; chest pain; changes in mood or behavior (including increased aggression); difficulty urinating; or ankle swelling while using either form of treatment, seek immediate medical attention.

Neither the testosterone patch nor gel should be used if you are diagnosed with prostate cancer or breast cancer. Always tell your physician which medications you are taking before starting a new one to avoid harmful interactions.

There is no set clearance period for the switch from a testosterone patch to gel or vice versa but it is essential to consult with your healthcare provider prior to making any changes. They will provide specific instructions based on your individual health profile and ensure that the transition occurs safely and effectively.

How much do Testosterone Patch and Gel cost?

For the brand name versions of these drugs:

  • The price for 30 patches of Androderm (a testosterone patch of 4 mg) averages around $670, which works out to approximately $22 per day.
  • The price for a single container (88 g or roughly one month's supply) of Testim gel (1%) is about $600, working out to approximately $20 per day.

Thus, if you are in the higher dosage range for Androderm (i.e., using two patches or more per day), then brand-name Testim gel may be less expensive on a per-day treatment basis. Please note that cost should not be a primary consideration in determining which form of testosterone replacement therapy is right for you.

For the generic versions of Androderm and Testim:

  • Generic testosterone patches are available with approximate costs starting from around $3.50 to about $10.00 per patch depending on dosage and quantity purchased. This translates into an average daily cost ranging from about $7-$20 assuming usage rate at one or two patches daily.
  • Generic testosterone gel can start as low as around $160 for a single container (up to 90 grams), translating into an average daily cost ranging between about $5-$6.

As always, prices may vary based on your pharmacy and any insurance coverage you might have.

Popularity of Testosterone Patch and Gel

Testosterone replacement therapy is frequently used to manage symptoms of testosterone deficiency, such as fatigue, depression and reduced libido. The two major forms of this treatment are testosterone patches and gels.

Testosterone gel was prescribed to approximately 1.5 million men in the USA in 2020. This accounts for just over half of all testosterone replacement prescriptions. Testosterone gels have been rising steadily in use since their introduction due to ease-of-use features like simple application and quick absorption.

On the other hand, about 500,000 prescriptions were written for testosterone patches in the same year. Although they account for a smaller percentage of total testosterone replacement prescriptions compared to gels (about 16%), their usage has remained relatively steady over the past decade. While some patients prefer patches because they provide a slow-release form of medication with less risk of transfer to others through skin contact, others find them more irritating or harder to adhere than gel.


Both the testosterone patch and gel are well-established treatment options for men with clinically low levels of testosterone, a condition known as hypogonadism. They both function by delivering testosterone transdermally (through the skin) to help restore normal hormone levels. The choice between these two treatment modalities often depends on patient preference and lifestyle.

The testosterone patch is typically applied once daily, usually in the evening, while the gel is also generally used once daily but can be applied at any time. Both forms of medication require an adjustment period during which dosages may be tweaked based on response and side effects.

Each has its own set of potential side effects: patches may cause skin irritation or rashes where they're applied, whereas gels carry a risk of unintentional transfer to others through close contact if not fully absorbed or covered appropriately. Both forms can potentially lead to increased red blood cell count, acne, enlarged breasts in males (gynecomastia), mood swings, or changes in sexual desire; thus patients need to monitor their health closely when initiating therapy.

Testosterone replacement should always be initiated under medical supervision due to its potential impact on prostate health among other considerations.
