Before Using
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 this medicine, the following should be considered:
Allergies
Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Pediatric
Appropriate studies have not been performed on the relationship of age to the effects of diazepam nasal spray in children younger than 2 years of age. Safety and efficacy have not been established. Diazepam nasal spray should not be used in infants and babies.
Geriatric
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of diazepam nasal spray in the elderly. However, elderly patients are more likely to have unwanted effects (eg, severe drowsiness, dizziness, clumsiness, or unsteadiness), which may require caution and an adjustment in the dose for patients receiving diazepam nasal spray.

Tell your doctor right away if your baby has an abnormal sleep pattern, diarrhea, feeding problems, a high-pitched cry, irritability, low muscle tone, restlessness, shakiness or tremors, sluggishness, trouble breathing, weight loss, vomiting, or fails to gain weight. If you think you have become pregnant while using the medicine, tell your doctor right away.

Check with your doctor right away if you have pale or blue lips, fingernails, or skin, difficult or trouble breathing, or irregular, fast or slow, or shallow breathing.
This medicine may make you drowsy, confused, or less alert than you are normally. Do not drive or do anything else that could be dangerous until you know how this medicine affects you.
This medicine may cause some people to be agitated, irritable, or display other abnormal behaviors. It may also cause some people to have suicidal thoughts and tendencies or to become more depressed.

Check with your doctor before using this medicine with alcohol or medicines that can affect the central nervous system (CNS). The use of alcohol or other medicines that affect the CNS with diazepam may worsen the side effects of this medicine, such as dizziness, poor concentration, drowsiness, unusual dreams, and trouble with sleeping. Some examples of medicines that affect the CNS are antihistamines or medicine for allergies or colds, sedatives, tranquilizers, or sleeping medicines, medicine for depression, medicine for anxiety, prescription pain medicine or narcotics, medicine for attention deficit and hyperactivity disorder, medicine for seizures or barbiturates, muscle relaxants, or anesthetics, including some dental anesthetics.

Call your doctor right away if you notice these symptoms.
Do not change your dose or suddenly stop using this medicine without first checking with your doctor. Your doctor may want you to gradually reduce the amount you are using before stopping it completely. This may help prevent a possible worsening of your seizures and reduce the possibility of withdrawal symptoms including burning, crawling, itching, numbness, prickling, "pins and needles", or tingling feelings, continuing ringing or buzzing or other unexplained noise in the ears, discouragement, false feeling of insects crawling on the skin, feeling sad or empty, hearing loss, irritability, lack of appetite, loss of interest or pleasure, trouble concentrating, or trouble sleeping.
