Thiothixene is used to treat certain mental/mood disorders (such as schizophrenia). This medicine helps you to think more clearly, feel less nervous, and take part in everyday life. It can reduce aggression and the desire to hurt yourself/others. It may also help to decrease hallucinations (such as hearing/seeing things that are not there). Thiothixene is a psychiatric medication (antipsychotic-type) that works by helping to restore the balance of certain natural substances (such as dopamine) in the brain.
If you miss a dose, take it as soon as you remember. If it is near the time of the next dose, skip the missed dose and resume your usual dosing schedule. Do not double the dose to catch up.
How To Use
Take this medication by mouth with or without food, usually 1-3 times daily or as directed by your doctor. Dosage is based on your medical condition and response to treatment. To reduce your risk of side effects such as drowsiness and shaking (tremor), your doctor may direct you to start this medication at a low dose and gradually increase your dose. Follow your doctor's directions carefully. Take this medication regularly in order to get the most benefit from it. To help you remember, take it at the same time(s) each day. Although you may notice some medication effects soon after starting, for some conditions it may take 2 to 3 weeks before you get the full benefit of this drug. Do not stop taking this medication without consulting your doctor. Some conditions may become worse when this drug is suddenly stopped. Also, you may experience symptoms such as severe confusion and hallucinations. To prevent these symptoms while you are stopping treatment with this drug, your doctor may reduce your dose gradually. Consult your doctor or pharmacist for more details. Report any new or worsening symptoms immediately. Tell your doctor if your condition does not improve or if it worsens.
The effects of some drugs can change if you take other drugs or herbal products at the same time. This can increase your risk for serious side effects or may cause your medications not to work correctly. These drug interactions are possible, but do not always occur. Your doctor or pharmacist can often prevent or manage interactions by changing how you use your medications or by close monitoring. To help your doctor and pharmacist give you the best care, be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products) before starting treatment with this product. While using this product, do not start, stop, or change the dosage of any other medicines you are using without your doctor's approval.

Other medications can affect the removal of thiothixene from your body, which may affect how thiothixene works. One example is carbamazepine. Other drugs not listed may also affect the removal. Tell your doctor or pharmacist if you are taking other products that cause drowsiness including alcohol, antihistamines (such as cetirizine, diphenhydramine), drugs for sleep or anxiety (such as alprazolam, diazepam, zolpidem), muscle relaxants, and narcotic pain relievers (such as codeine). Check the labels on all your medicines (such as allergy or cough-and-cold products) because they may contain ingredients that cause drowsiness. Ask your pharmacist about using those products safely. Also tell your doctor if you take any drugs that might increase your risk of a seizure when combined with thiothixene, such as bupropion, isoniazid (INH), phenothiazines (like thioridazine, chlorpromazine), theophylline, tramadol, and tricyclic antidepressants (like amitriptyline), among others.
