It can also be used to treat tension, agitation, and irritability in older patients. Oxazepam is a benzodiazepine.

Precautions while using Serax

It is very important that your doctor check your progress at regular visits to ensure this medicine is working properly. Blood tests may be needed to check for unwanted effects.

This medicine is for short-term use only, which is usually considered less than 4 months. If your condition does not improve or if it gets worse, check with your doctor.

Using this medicine while you are pregnant can harm your unborn baby. Use an effective form of birth control to prevent getting pregnant. If you think you have become pregnant while using this medicine, tell your doctor right away.

This medicine may cause some people, especially older individuals, to feel drowsy, dizzy, lightheaded, clumsy, unsteady, or less alert than usual. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are not alert or able to think or see well.

This medicine will increase the effects of alcohol and other central nervous system (CNS) depressants. CNS depressants are medicines that slow down the nervous system, possibly causing drowsiness or making you less alert. Some examples of CNS depressants include antihistamines or medicines for hay fever, allergies, or colds, sedatives, tranquilizers, or sleeping medicines, prescription pain medicines or narcotics, barbiturates or medicines for seizures, muscle relaxants, or anesthetics (numbing medicines), including some dental anesthetics. This effect may last for a few days after you stop taking this medicine. Check with your doctor before taking any of the above while using this medicine.

Do not stop taking this medicine without checking with your doctor first. Your doctor may want you to gradually reduce the amount you are using before stopping it completely. This may help prevent your condition from worsening and reduce the possibility of withdrawal symptoms, including hallucinations, nausea or vomiting, seizures, stomach or muscle cramps, tremors, sweating, or unusual behavior.

This medicine may be habit-forming. If you feel that the medicine is not working as well, do not take more than your prescribed dose. Call your doctor for instructions.

Symptoms of an overdose include: blurred vision, change in consciousness, dizziness, faintness, or lightheadedness when getting up suddenly from a lying or sitting position, loss of consciousness, loss of strength or energy, confusion, muscle pain or weakness, shakiness and unsteady walk, sleepiness or unusual drowsiness, dullness, tiredness, weakness or feeling of sluggishness, sweating, or unsteadiness, trembling, or other problems with muscle control or coordination. Call your doctor right away if you notice these symptoms.

Before using Serax

In deciding to use a medicine, the risks of taking the medicine must be weighed against the benefits it will provide. This is a decision you and your doctor will make together. 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 inform your healthcare professional if you have any other 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 effects of oxazepam in children younger than 6 years. Safety and effectiveness have not been established for this age group.

Geriatric

Appropriate studies done so far have not shown specific problems in older adults that would limit the usefulness of oxazepam. However, older patients are more likely to experience side effects (such as severe drowsiness, dizziness, lightheadedness, fainting, unusual behavior) and age-related kidney or liver issues, which may require caution and a dose adjustment for those taking oxazepam.

Breast Feeding

There are no adequate studies in women to determine the risk to infants when using this medication while breastfeeding. Weigh the potential benefits against the risks before taking this medication while breastfeeding.
