Precautions

As with most antipsychotic medications, Navane carries with it significant risk and hazards. Your doctor, pharmacist, and/or health care provider should discuss the following information with you prior to prescribing you this drug:

• This drug is not recommended for older adults with dementia. An examination of 17 controlled trials over a 10-week period revealed that elderly people experiencing dementia-related psychosis, who were treated with antipsychotic medication, were almost two times as likely to die from cardiovascular conditions, infections, or other related issues than people who received a placebo.
• If you have ever been diagnosed with glaucoma, enlarged prostate, seizures, breast cancer, low white blood cell count, low platelets, anemia, or heart disease, you should talk to your doctor before you start taking this drug. You should also mention current or past alcohol dependency, alcohol withdrawal issues, and any serious reactions you may have had to other similar medications.
• This drug may interact with other medications, so check with your doctor or pharmacist if you are taking other prescription drugs or supplements. Vitamins, minerals and herbal products—particularly the herb St. John’s wort—may affect the effectiveness of this drug.
• Thiothixene, the active ingredient in Navane, may interfere with the results of home pregnancy tests.
• Long-term treatment with this drug may lead to a serious and potentially irreversible movement condition called tardive dyskinesia.
• Using antipsychotic medication may increase the chances of developing neuroleptic malignant syndrome (NMS). This condition may be fatal.

Safety Considerations

As you begin your treatment with Navane, you should be aware of the following warnings:

• If you are pregnant or become pregnant while taking Navane, you should talk to your doctor about alternative treatments for your condition. Navane can cause problems in newborns, particularly if taken during the third trimester of pregnancy. Newborns may experience issues such as tremors, stiff muscles, limp muscles, feeding issues, difficulty breathing, fussiness, and withdrawal symptoms. However, you should not stop taking this drug—even if you become pregnant—unless directed to do so by your doctor.
• If this medication causes an upset stomach, you may take it with food or just after a meal to reduce this effect.
• If you are having any type of surgery, including oral surgery, your surgeon or anesthesiologist needs to know that you are taking Navane.

This medication may make your skin more sensitive to sunlight. Be sure to wear protective clothing and use sun block (at least SPF 30) if you plan to spend a lot of time outside. Do not use tanning beds while taking this drug. Try not to become overheated or dehydrated when exercising, especially in very hot weather. This medication may lead to a decrease in perspiration and increase the risk of a heat injury such as heatstroke.

Avoid drinking alcoholic beverages during treatment. Alcohol may cause an increase in the number and severity of side effects experienced from taking this drug. Thiothixene may also increase the effects of alcohol. Be extremely cautious if you operate heavy machinery or drive while taking this medication. This drug may reduce your alertness, thinking ability and reaction time.
