Seroquel (Quetiapine) is a prescription drug used to treat schizophrenia and bipolar disorder
One of the most commonly reported side effects of Seroquel is weight gain. This can have harmful consequences for overall health, impacting the heart, lungs, liver, pancreas, and other organs. Additionally, Seroquel is associated with an increased risk of metabolic problems, including high blood sugar or hyperglycemia, which can lead to diabetes. Other metabolic changes that may occur include dyslipidemia.
Seroquel may also cause muscle weakness and uncontrolled movements, including muscle twitching, jerking, spasms, tremors, and stiffness. These side effects can affect an individual's balance, coordination, and risk of falling. In some cases, muscle stiffness may be a symptom of a more serious condition called neuroleptic malignant syndrome (NMS).
The drug can also impact the thyroid gland, leading to low thyroid levels or hypothyroidism. This, in turn, can cause various symptoms, including feeling weak, tired, or confused, and experiencing dizziness, vomiting, or an upset stomach. It is crucial to monitor thyroid function and consult a healthcare provider if any of these symptoms occur.
While less common, Seroquel may also cause serious allergic reactions and increase the risk of suicidal thoughts and behaviours, especially in children, adolescents, and young adults. It is important to monitor for any emergence or worsening of suicidal thoughts and behaviours and to seek medical attention if they occur.

Common side effects include drowsiness, weight gain, muscle twitching, and stiffness
Seroquel (Quetiapine) is a prescription drug used to treat schizophrenia and certain types of bipolar disorder. It is associated with a range of side effects, some of which are mild and temporary, while others are more serious and long-lasting.
Some of the most commonly reported side effects of Seroquel include drowsiness, weight gain, muscle twitching, and stiffness. Drowsiness or sleepiness is a common side effect, which may cause decreased alertness or coordination and an increased risk of falls. It is important to refrain from driving or operating machinery until you know how Seroquel affects you. This side effect usually improves as your body adjusts to the medication, but if it persists, consult your doctor.
Weight gain is another frequent occurrence, which can have harmful effects on the heart, lungs, and other organs. It is also linked to metabolic problems like increased blood sugar or hyperglycemia, which can lead to diabetes. It is important to follow your doctor's advice regarding diet and exercise to manage weight gain and reduce these associated risks.
Muscle twitching, spasms, and uncontrolled movements are also common side effects of Seroquel. These movements can occur in the face, tongue, or other parts of the body and may be accompanied by stiffness or jerking. In some cases, these symptoms can indicate a more serious condition, such as neuroleptic malignant syndrome (NMS), which requires immediate medical attention.
While these side effects are relatively common, not everyone taking Seroquel will experience them. It is important to consult your healthcare provider if you have any concerns or experience any adverse effects, as they can guide you on managing these symptoms and determining your individual risks.

Serious side effects are rare but may include neuroleptic malignant syndrome, blood clots, and stroke
Seroquel (Quetiapine) is an antipsychotic medication that can cause a range of side effects, most of which are typically mild. However, in rare cases, more serious adverse reactions may occur, including neuroleptic malignant syndrome (NMS), blood clots, and stroke.
Neuroleptic malignant syndrome is a rare and potentially life-threatening condition that can occur as a reaction to neuroleptic or antipsychotic medications. NMS is characterised by a high fever, muscle stiffness, and significant changes in blood pressure. It typically develops over one to three days, and other symptoms may include an irregular heartbeat, a fast heart rate, and increased muscle stiffness. NMS can be caused by a single dose, an increasing dose, or the same dose of neuroleptic medication, and it is primarily associated with first-generation antipsychotics. While NMS is rare, affecting approximately 0.01% to 3.2% of people taking neuroleptic medications, it can be life-threatening and requires immediate medical attention.
Blood clots are another rare but serious potential side effect of Seroquel. Signs of blood clots may include swelling, pain, or redness in the leg, chest pain, and difficulty breathing. If any of these symptoms occur, it is important to seek medical advice as soon as possible, as blood clots can be life-threatening if left untreated.
Additionally, Seroquel may slightly increase the risk of stroke, particularly in older adults with memory loss or psychosis related to dementia. This increased risk is also observed with other antipsychotic medications. Other risk factors, such as high blood pressure, diabetes, and smoking, can also contribute to the likelihood of experiencing a stroke. Therefore, it is crucial to discuss any concerns with a healthcare professional and carefully consider the potential benefits and risks of taking Seroquel or any other medication.

Long-term use may cause metabolic changes, increasing the risk of diabetes and cardiovascular issues
Seroquel (Quetiapine) is a prescription drug used to treat schizophrenia and certain types of bipolar disorder. It can be taken short-term or long-term, depending on the condition. While Seroquel can be beneficial for managing these conditions, long-term use may cause metabolic changes that increase the risk of diabetes and cardiovascular issues.
One of the most commonly reported side effects of Seroquel is weight gain. Excess weight can have detrimental effects on the heart, lungs, stomach, liver, pancreas, and other organs. Additionally, Seroquel has been linked to an increased risk of metabolic problems, including high blood sugar or hyperglycemia. This can lead to a sudden drop in blood pH levels (ketoacidosis), coma, or even death. Signs of persistent hyperglycemia include increased thirst, frequent urination, heightened hunger, and feelings of weakness or fatigue.
The link between Seroquel and diabetes is well-established. Clinical trials have shown that a notable percentage of patients with initially normal fasting plasma glucose (FPG) levels experienced elevated readings during treatment with Seroquel. For those with already elevated baseline FPG levels, the risk of hyperglycemia was even higher. These metabolic changes can have significant implications for cardiovascular health.
Furthermore, Seroquel can cause changes in heart rhythm, such as QT prolongation, which affects the way the heart beats and can lead to fainting or other serious side effects. Elderly patients taking Seroquel are particularly susceptible to cardiovascular issues. They may experience an increased risk of death due to underlying conditions such as dementia or age-related heart, liver, or kidney problems.
It is important to note that while these metabolic and cardiovascular risks are associated with long-term Seroquel use, individual experiences may vary. Consulting a healthcare professional is essential to understanding the potential benefits and risks of taking Seroquel. They can provide guidance on managing these risks through lifestyle modifications, such as maintaining a healthy weight through diet and exercise, and closely monitoring metabolic and cardiovascular health indicators.

Seroquel may also cause hormonal changes, impacting fertility and sexual function in both men and women
Seroquel (Quetiapine) is a prescription medication used to treat serious mental illnesses like bipolar disorder and schizophrenia. It is classified as an atypical, second-generation antipsychotic drug. While Seroquel has many benefits, it also carries the risk of side effects and potential long-lasting health consequences.
One of the known side effects of Seroquel is its potential impact on hormonal changes, which can affect fertility and sexual function in both men and women. In men, Seroquel use has been associated with increased breast tissue (gynecomastia). For women, the drug can cause irregular or absent menstrual periods (dysmenorrhea or amenorrhea). These hormonal changes can also lead to a lowered interest in sex or decreased ability to perform sexually for both genders.
The impact of Seroquel on fertility is a concern and has been studied in the context of antipsychotic medications. Antipsychotic drugs, including Seroquel, can block dopamine D2 receptors, leading to increased prolactin levels (hyperprolactinemia). This hormonal imbalance can cause irregular menstrual cycles and anovulation in women by altering estrogen and FSH levels. Women with elevated prolactin levels may also experience a decrease in libido, galactorrhea (milk leakage from breasts), and a possible increased risk of osteoporosis.
It is important to note that the impact of antipsychotic medications on fertility is reversible upon discontinuation of the drug. However, individuals should consult their doctors before making any changes to their medication. Additionally, the full extent of Seroquel's effects on fertility and sexual function may not be fully understood, and further research is needed.
Other side effects of Seroquel include weight gain, metabolic problems such as increased blood sugar, thyroid issues, swallowing difficulties, increased body temperature, seizures, and cardiac issues when combined with other medications. Serious side effects, such as uncontrollable movements, heart rate changes, vision changes, and trouble breathing, may occur but are uncommon.
