A myoma is a type of tumor that involves muscle cells. There are two main types of myoma: 

Leiomyomas which occur in smooth muscle. They most commonly occur as uterine fibroids, but may also form in other locations. Rhabdomyomas which occur in striated muscle. They are rare tumors, occur in childhood and often become malignant.Whether or not angiomyomas are a type of leiomyoma or a separate entity is disputed as of 2014.Myomas are benign tumors of the uterus that can affect the fertility of a woman depending mainly on three factors:

Size (cut off value 4-5 cm)
Number
Location (they can be intramural, subserous or submucous). Submucous ones are worst from a fertility point of view, while subserous are less dangerous.Some of the most common symptoms are: abundant menstrual bleeding, longer menstrual periods, pelvic pressure, constipation, a need to urinate continuously.

Other uses
Risperidone has shown promise in treating therapy-resistant obsessive-compulsive disorder, when serotonin reuptake inhibitors alone are not sufficient.Risperidone has proven to be effective in treatment with Attention deficit hyperactivity disorder especially in cases of aggression or with another mental condition.Risperidone has not demonstrated a benefit in the treatment of eating disorders or personality disorders, except for limited evidence in schizotypal personality disorder. Forms
Available forms of risperidone include tablet, oral dissolving tablet, oral solution, and powder and solvent for suspension for injection. Adverse effects
Common side effects include movement problems, sleepiness, dizziness, trouble seeing, constipation, and increased weight. About 9 to 20% of people gained more than 7% of the baseline weight depending on the dose. Serious side effects may include the potentially permanent movement disorder tardive dyskinesia, as well as neuroleptic malignant syndrome, an increased risk of suicide, and high blood sugar levels. In older people with psychosis as a result of dementia, it may increase the risk of death.While atypical antipsychotics appear to have a lower rate of movement problems as compared to typical antipsychotics, risperidone has a high risk of movement problems among the atypicals. Atypical antipsychotics, however, are associated with a greater amount of weight gain and other metabolic side effects. Drug interactions
Carbamazepine and other enzyme inducers may reduce plasma levels of risperidone. If a person is taking both carbamazepine and risperidone, the dose of risperidone will likely need to be increased. The new dose should not be more than twice the patients original dose.
