Short description

Cytomel, used alone or with other medicines, should not be used to treat obesity or for weight loss. Large doses may cause serious or life-threatening situations, particularly when used with other medicines that reduce the appetite.


Cytomel is used in medical practice to treat various conditions associated with insufficient levels of thyroid hormones, such as hypothyroidism.

Today, Cytomel has found widespread use not only in medical practice but also in bodybuilding, where it is used to improve overall fitness and weight loss. Due to its ability to speed up metabolism and stimulate fat burning.


Everybody is unique, and the needs for liothyronine can vary significantly. Before starting a course of Cytomel, it is recommended to consult with a doctor or endocrinology specialist to determine an individualized dosage. The doctor takes into account the level of thyroid hormones in the body and the characteristics of thyroid disease.

Initial dosage: The initial dose of Cytomel is 25 mcg per day. It can be increased gradually, depending on the body's response. This approach avoids abrupt changes and minimizes possible side effects.

Weight Loss: For those using Cytomel for weight loss and metabolic acceleration, it is recommended to start with a lower dose, such as 12.5 mcg per day. Gradually increasing the dose allows the body to adapt, reducing the risk of possible side effects.

Splitting the daily dose: To ensure stable levels of liothyronine in the body, the daily dose is often divided into two or three doses. This may also reduce the chance of side effects associated with sudden changes in hormone levels.

Monitoring: It is important to closely monitor your body's response to Cytomel use. Regular testing of thyroid hormone levels will help maintain optimal dosages and prevent potential problems.

Completing the course and post-course therapy: When completing a course of Cytomel, it is important to gradually reduce the dosage, preventing a sudden drop in hormone levels. Post-course therapy may also be prescribed to restore the body's natural balance.


The drug Cytomel, is a powerful tool for regulating the thyroid gland. However, as with any medication, there are contraindications that are important to consider before beginning a course of treatment.

Allergic Reaction: Patients with a known allergy to liothyronine sodium or any other component of Cytomel should refrain from using the drug. Allergy manifestations may range from skin rashes to more serious systemic reactions.

Heart disease: People with serious heart conditions such as angina, heart failure, or arrhythmias should use Cytomel with caution. The drug may increase the strain on the heart, which increases the risk of complications.

Hyperthyroidism: The use of the drug is contraindicated in patients with hyperthyroidism, a condition in which the thyroid gland produces excessive amounts of hormones. The drug may aggravate this condition, leading to serious consequences.

Coronary heart disease: People with coronary heart disease, especially after a myocardial infarction, should also use Cytomel with caution. The drug may worsen ischemia and increase the risk of new heart problems.

Kidney diseases: Patients with severe kidney diseases are recommended to avoid the use of the drug or use it with extreme caution. The drug may affect kidney function and electrolyte levels in the body.

Pregnancy and breastfeeding: The drug Cytomel is contraindicated in pregnancy and during breastfeeding. Liothyronine sodium may penetrate the placenta and enter the mother's milk, which may affect the health of the baby.

Diabetes Mellitus: Patients with diabetes should also use Cytomel with caution, as the drug may affect blood glucose levels.

Other endocrine disorders: People with other endocrine disorders, such as thyroid hypofunction require special attention when using Cytomel. Using the drug without medical supervision may cause hormonal imbalances.

Individual sensitivity: Individual sensitivity to the drug may also be a contraindication. If the patient has had a negative reaction to similar drugs, one should refrain from using Cytomel. 

Side Effects

Increased heartbeat and arrhythmias: One of the most common side effects of Cytomel is an increased heartbeat. The drug stimulates metabolism, which can affect heart activity. People with a predisposition to arrhythmias or heart problems should use Cytomel with caution.


  • Nervousness and Anxiety: Increased thyroid hormone levels may cause nervousness and anxiety. Patients with existing stress problems or anxiety disorders are advised to discuss the possible risks with their doctor. 

  • Insomnia: Changes in hormone levels can also affect the sleep cycle. Many patients report insomnia while using Cytomel. Regular sleep is important for overall health, so you should pay attention to this side effect if you have trouble sleeping. 

  • Increased blood pressure: Cytomel may cause an increase in blood pressure. This is especially important for people with hypertension or other cardiovascular problems. It is important to measure your blood pressure and consult your doctor before using the drug. 

  • Weight loss and muscle fatigue: Because Cytomel is often used to lose weight and boost metabolism, weight loss may occur. However, if overused or improperly dosed, it can lead to muscle fatigue and weakness. 

  • Changes in emotional state: Thyroid hormones affect your overall emotional state. Some patients may experience mood changes, irritability and depression while using Cytomel. 

  • Heat Flashes and Excessive Sweating: Increased metabolic activity may also be accompanied by heat flashes and excessive sweating. These symptoms may be particularly pronounced at the beginning of taking the drug. 

  • Stomach and digestive problems: Some patients report stomach problems, nausea, or changes in appetite while using Cytomel. This may affect the absorption of the drug and overall comfort. 

  • Allergic Peakactions: Although rare, some people may develop allergic reactions to the drug, manifesting as skin rashes, itching, or swelling. 

  • Risk of overdose: Improper dosage or increasing the dose without consulting a doctor can lead to an overabundance of hormones, which can cause serious complications, including a thyrotoxic crisis.

Interaction with other medicinal products: Safety and caution in combination

To maximize the efficacy and safety of therapy, it is important to consider the interactions of this drug with other medications.

·       Beta-blockers or antiarrhythmic agents

·       Iron-containing drugs

·       Drugs containing calcium or aluminum, such as antacids

·       Drugs that affect the gastrointestinal tract

·       Insulin and other drugs that affect blood glucose levels

·       Antidepressants or sedatives

·       Anticoagulants

·       Drugs that affect the kidneys 

It is important to emphasize that any changes in treatment regimen, including starting or stopping other medications, should be supervised by a physician. Only a qualified medical professional will be able to assess the risks and benefits of Cytomel interactions with other drugs in the context of individual patient characteristics.

Duration of Action

Cytomel begins to exert its effects relatively quickly, usually within a few hours of ingestion. Peak effect is usually achieved within 2–3 hours. This allows for a fairly rapid effect on the level of hormones in the blood. The drug is taken one or more times a day. The distribution of the dose may affect the stability of hormone levels in the blood.

The main effect of Cytomel lasts for approximately 24–48 hours after administration. This is due to the relatively short elimination half-life of liothyronine in the body.

The duration of action of Cytomel may vary depending on individual body characteristics, general health, and individual sensitivity to the drug. The rate of metabolism and excretion of the drug from the body may vary from patient to patient. It also depends on the dosage and distribution of intake.

In bodybuilding and sports, Cytomel is often used to activate metabolism and accelerate fat burning. In such cases, it may be taken cyclically, followed by a break, to avoid the development of tolerance to the drug.

In some cases, Cytomel may be used short-term to quickly affect hormone levels. It may also be used prophylactically to maintain optimal thyroid hormone levels.

Foods, especially those rich in calcium, iron or fiber, may affect the absorption of Cytomel and therefore its duration of action. Your doctor can recommend the optimal time to take the drug in relation to food intake.

An important consideration when using Cytomel is post-course therapy and gradual dose reduction. This helps to avoid a sharp drop in hormone levels after the end of the course.

Use of Cytomel in bodybuilding

Cytomel has found widespread use in bodybuilding due to its effects on thyroid hormone levels. Here's how the use of Cytomel can affect bodybuilding results:

Metabolic Acceleration: One of the key effects of Cytomel in bodybuilding is its ability to speed up metabolism. The drug stimulates the production of thyroxine and triiodothyronine, increasing energy metabolism in cells. This helps athletes reduce their fat percentage and improve their overall muscle definition.

Fat Burning: Cytomel is often used for fat burning and muscle maintenance during periods of weight loss. Increased thyroid hormone levels stimulate the breakdown of fat into energy, which promotes more efficient calorie burning.

Maintaining energy during calorie deficits: During competition preparation or weight loss, bodybuilders often subject themselves to calorie deficits. Cytomel can help maintain high energy levels while reducing calories, which is important to support intense workouts.

Improved muscle definition: Through its effects on metabolism, Cytomel promotes muscle expression, making muscles more defined and contrasting. This is especially important in bodybuilding, where muscle detailing is a key aspect of aesthetics.

Preventing loss of muscle mass: With calorie reduction and intense exercise, there is a risk of losing muscle mass. Cytomel helps minimize this risk by encouraging the efficient use of fat as an energy source, leaving protein to maintain muscle.

Improved overall workout performance: Bodybuilders who use Cytomel often report improved overall workout performance. Increased energy levels and an accelerated metabolism can contribute to more productive and intense workouts.

Cyclic Use and Post-Course Perapia: In bodybuilding, Cytomel is often used cyclically, followed by a rest period. This helps avoid tolerance to the drug and reduces the risk of side effects.

Size Control: Due to its effects on metabolism, Cytomel can also help bodybuilders control body size by maintaining optimal proportions.

It is important to emphasize that the use of Cytomel in bodybuilding requires caution and should be taken under the supervision of a physician. The dosage and regimen should be tailored to the individual needs and characteristics of each athlete.
