Before Using This Medicine
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For thiethylperazine, the following should be considered:
Allergies- Tell your doctor if you have ever had any unusual or allergic reaction to thiethylperazine or other phenothiazine medicines. Also tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes.
Pregnancy- Thiethylperazine is not recommended during pregnancy. Other phenothiazine medicines have been reported to cause unwanted effects, such as jaundice and muscle tremors and other movement disorders, in newborn babies whose mothers took these medicines during pregnancy.
Breast-feeding- It is not known if thiethylperazine passes into breast milk. However, thiethylperazine is not recommended for use during breast-feeding because there is the chance that it may cause unwanted effects in nursing babies.
Children- Children are usually more sensitive than adults to the effects of phenothiazine medicines such as thiethylperazine. Certain side effects, such as muscle spasms of the face, neck, and back, tic-like or twitching movements, inability to move the eyes, twisting of the body, or weakness of the arms and legs, are more likely to occur in children, especially those with severe illness or dehydration.
Older adults- Elderly patients are usually more sensitive to the effects of phenothiazine medicines such as thiethylperazine. Confusion; difficult or painful urination; dizziness; drowsiness; feeling faint; or dryness of mouth, nose, or throat may be more likely to occur in elderly patients. Also, nightmares or unusual excitement, nervousness, restlessness, or irritability may be more likely to occur in elderly patients. In addition, uncontrolled movements may be more likely to occur in elderly patients taking thiethylperazine.
Other medicines- Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking thiethylperazine, it is especially important that your health care professional know if you are taking any of the following:

Thiethylperazine will add to the effects of alcohol and other CNS depressants (medicines that cause you to feel drowsy or less alert). Some examples of CNS depressants are antihistamines or medicine for hay fever, other allergies, or colds; sedatives, tranquilizers, or sleeping medicine; prescription pain medicine or narcotics; barbiturates; medicine for seizures; muscle relaxants; or anesthetics, including some dental anesthetics. Check with your doctor before taking any of the above while you are using this medicine .

Thiethylperazine may cause dryness of the mouth, nose, and throat. For temporary relief of mouth dryness, use sugarless candy or gum, melt bits of ice in your mouth, or use a saliva substitute.
