Effects on Newborns:
In some cases, babies born to a mother taking LATUDA during pregnancy have experienced symptoms that are severe and require the newborn to be hospitalized. Sometimes, the symptoms may resolve on their own. Be prepared to seek immediate emergency medical attention for your newborn if they have difficulty breathing, are overly sleepy, have muscle stiffness, or floppy muscles (like a rag doll), are shaking, or are having difficulty feeding.
Because some people experience drowsiness, you should not drive or operate machinery until you are reasonably certain that LATUDA does not affect your ability to carry out these activities.
Some people may faint, or experience symptoms such as lightheadedness and dizziness, especially when getting up from a lying or sitting position. This is more likely to happen if you are elderly and also in the early stages of treatment or following dose increases. This will usually pass on its own but if it does not, tell your doctor.
Since medications of this type may interfere with the ability of the body to adjust to heat, it is best to avoid becoming overheated or dehydrated (for example, with vigorous exercise or exposure to extreme heat) while taking LATUDA.
The most common side effects of LATUDA in patients with schizophrenia are:
- feeling of restlessness (akathisia)
- abnormal movements, tremor, muscle stiffness, slowing of movement
The most common side effects of LATUDA in patients with depression associated with bipolar disorder are:
- feeling of restlessness (akathisia)
- abnormal movements, tremor, muscle stiffness, slowing of movement.
The following other side effects may also happen in some people who take LATUDA:
- Symptoms of an allergic reaction including rash, itching, flushing, and/or inflammation of the mouth and/or skin (see also Serious Side Effects, How Often They Happen and What to Do About Them).
- Increase in the amount of sugar (glucose) in the blood (hyperglycemia). Symptoms of high blood sugar can include feeling very thirsty and/or hungry, needing to urinate more than usual, feeling weak or tired, feeling sick to your stomach, feeling confused, fruity smelling breath.
- Decreased blood pressure. Symptoms of decreased blood pressure can include lightheadedness or fainting when rising too quickly from a sitting or lying position.
The following may also occur with LATUDA, and may be seen in routine blood testing:
- decrease in the amount of white blood cells
- increase in the amount of hormone prolactin in the blood which:
- in women, may lead to swelling of breasts and unexpected production of breast milk and changes in the regularity of monthly periods; and
- in men, may lead to diminished sexual function and breast enlargement
If you have high levels of prolactin (measured with a blood test) and a condition called hypogonadism you may be at an increased risk of breaking a bone due to osteoporosis. This occurs in both men and women.
Your doctor should check your body weight before starting LATUDA and continue to monitor it for as long as you are being treated.
Your doctor should take blood tests before starting LATUDA. They will monitor blood sugar and the number of infection fighting white blood cells. Your doctor should continue to monitor your blood for as long as you are being treated.
