Important Information about Invega
Invega should not be used in patients whose psychosis is related to dementia. Use of Invega in these patients can lead to heart failure, sudden death or pneumonia. Dementia is not a specific disease in and of itself. Rather it refers to a group of symptoms that affect intellectual and social abilities so much that it interferes with the ability to function normally in everyday situations.
Schizophrenia, as opposed to dementia, is a disease. It is chronic, severe and disabling. It affects about 2 percent of the U.S. population at any one time. Seeing or hearing noises that are not there are some symptoms of schizophrenia that lead to other problems.
When patients take Invega:
- They may be more sensitive to temperature extremes and should avoid becoming overheated, dehydrated or too cold
- They should drink extra fluids, particularly when it is hot or when they exercise
- Thinking and reaction time may be impaired (care should be taken when driving or operating machinery)
- They may become sleepy and be especially susceptible to medication that makes them tired, including medication to treat colds and allergies, sedatives, narcotics for pain, sleeping pills, muscle relaxants, anti-seizure, depression or anxiety medicines and alcohol
Invega users should discontinue the medication immediately and call their doctor if they experience the following serious symptoms:
- Rigid muscles
- High fever
- Fast or uneven heartbeats
- Restless movements of the muscles in the face or neck
- Problems swallowing
- Feeling faint
Invega and the Risk for Gynecomastia
Gynecomastia, a condition in which males develop enlarged breasts, can be a side effect of Invega, particularly for younger males and adolescents. The condition was noticed as early as during the days of Tutankhamun.
Other drugs can lead to gynecomastia, although these usually cause the condition in adult men. These medications include:
- Anti-androgen treatment for prostate cancer
- Antiretroviral drugs for HIV
- Calcium antagonists for hypertension
- Some antibiotics
- Certain drugs to treat ulcers
- Some chemotherapy drugs for children
- Anabolic steroids
- Alcohol, marijuana, heroin, and amphetamine abuse
Consult your doctor to find out if Invega is right for you. If your son is prescribed Invega, it is important to be aware that he may develop gynecomastia, a condition that can cause serious psychological and emotional problems. If your son or you have already been diagnosed with gynecomastia and have a history of taking Invega, you may qualify for financial compensation. To learn more, contact our Invega lawyers today.
