Diazepam Injection Side Effects Center
Medical Editor: John P. Cunha, DO, FACOEP
Diazepam Injection (brand name: Valium) is used to treat anxiety and muscle spasms. The injection form is used when the medication cannot be taken by mouth. It is also used in patients with alcohol withdrawal to prevent seizures and treat other symptoms (e.g., agitation, anxiety, hallucinations), for short-term treatment of serious seizures that do not stop (status epilepticus), or before surgeries or procedures to cause drowsiness, decrease anxiety, and cause forgetfulness about the procedure or surgery. This medication belongs to a class of drugs called benzodiazepines. It is available in generic form. Common side effects include drowsiness, dizziness, nausea, unsteadiness, or pain/burning/redness at the injection site.
Dosage of Diazepam Injection depends on the condition being treated and its severity. The usual recommended dose in older children and adults ranges from 2 mg to 20 mg I.M. or I.V. Diazepam Injection may interact with fluvoxamine, kava, phenytoin, cimetidine, ketoconazole, omeprazole, antihistamines, anti-seizure drugs, medicine for sleep or anxiety, muscle relaxants, narcotics, or psychiatric medicines. This medication contains a small amount of alcohol. Tell your doctor if you are taking drugs such as disulfiram or metronidazole that can adversely interact with alcohol. Diazepam Injection is not recommended for use during pregnancy. It may harm a fetus. This drug may pass into breast milk and have undesirable effects on a nursing infant. Breast-feeding while using this medication is not recommended. Diazepam Injection may cause withdrawal symptoms (shakiness, trouble sleeping, muscle cramps, vomiting, sweating, seizures, mental/mood changes such as anxiety/agitation) if you suddenly stop using this medication.

Diazepam Injection FDA Prescribing Information: Side Effects
CNS: confusion, depression, dysarthria, headache, hypoactivity, slurred speech, syncope, tremor, vertigo. G.I.: constipation, nausea. G.U.: incontinence, changes in libido, urinary retention. Cardiovascular : bradycardia, cardiovascular collapse, hypotension. EENT: blurred vision, diplopia, nystagmus. Skin: urticaria, skin rash. Other: hiccups, changes in salivation, neutropenia, jaundice. Paradoxical reactions such as acute hyperexcited states, anxiety, hallucinations, increased muscle spasticity, insomnia, rage, sleep disturbances and stimulation have been reported; should these occur, use of the drug should be discontinued. Minor changes in EEG patterns, usually low-voltage fast activity, have been observed in patients during and after diazepam therapy and are of no known significance.
Because of isolated reports of neutropenia and jaundice, periodic blood counts and liver function tests are advisable during long-term therapy.
Drug Abuse And Dependence
Withdrawal symptoms, similar in character to those noted with barbiturates and alcohol (convulsions, tremor, abdominal and muscle cramps, vomiting and sweating), have occurred following abrupt discontinuance of diazepam. The more severe withdrawal symptoms have usually been limited to those patients who had received excessive doses over an extended period of time. Generally milder withdrawal symptoms (e.g., dysphoria and insomnia) have been reported following abrupt discontinuance of benzodiazepines taken continuously at therapeutic levels for several months. Consequently, after extended therapy, abrupt discontinuation should generally be avoided and a gradual dosage tapering schedule followed. Addiction-prone individuals (such as drug addicts or alcoholics) should be under careful surveillance when receiving diazepam or other psychotropic agents because of the predisposition of such patients to habituation and dependence.
