Doral (quazepam) is a benzodiazepine used to treat insomnia symptoms, such as trouble falling or staying asleep. Common side effects of Doral include dizziness, spinning sensation (vertigo), loss of balance or coordination, blurred vision or other vision problems, daytime drowsiness (or during hours when you are not normally sleeping), amnesia or forgetfulness, confusion, muscle weakness, insomnia or nightmares, headache, depression, nervousness, excitement, irritability, impotence, loss of interest in sex, itching or skin rash, nausea, diarrhea, stomach pain, loss of appetite, dry mouth, or increased thirst.
The initial adult dose of Doral is 15 mg. In some patients, the dose may be reduced to 7.5 mg. Doral may interact with other medications that cause drowsiness (such as cold or allergy medicine, sedatives, narcotics, muscle relaxers, and medicine for seizures, depression or anxiety), bupropion, cyclophosphamide, efavirenz, irinotecan, promethazine, or selegiline. Tell your doctor all medications and supplements you use. Doral must not be used during pregnancy. Other medications in this class have caused birth defects when used in the first three months of pregnancy, and have also caused unusual drowsiness, feeding problems, and liver problems in newborns when used at or near the time of delivery, or withdrawal symptoms in newborns when used for a long time during pregnancy. Women should use birth control while taking this drug. If you become pregnant or think you may be pregnant, inform your doctor. This medication passes into breast milk and may have undesirable effects on a nursing infant. Breastfeeding while using this drug is not recommended. Withdrawal symptoms may occur if you suddenly stop taking this medication.

Doral Overview - Patient Information: Side Effects
This medication may make you sleepy during the day. Tell your doctor if you have daytime drowsiness. Your dose may need to be adjusted.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Tell your doctor immediately if any of these unlikely but serious side effects occur: confusion, unusual feelings of well-being (euphoria), uncontrolled movements (tremor), restlessness, memory loss, sweating, mental/mood changes (e.g., hallucinations, agitation, anxiety, unusual/disturbing thoughts, depression, rare thoughts of suicide), increased or vivid dreams, vision changes, fainting.
Tell your doctor immediately if any of these rare but very serious side effects occur: signs of infection (e.g., fever, persistent sore throat), unusual paleness, unusual tiredness, fast/pounding/irregular heartbeat, yellowing of the eyes/skin, dark urine.
Some people who take sleep medications have reported getting out of bed and sleepwalking, driving, eating, talking on the phone, or having sex while not fully awake. Often they do not remember these activities. This problem can be dangerous to you or to others. If you find out that you have done any of these activities after taking this medication, tell your doctor immediately. Your risk is increased if you use alcohol or other medications that can make you drowsy while taking quazepam.
A very serious allergic reaction to this drug is unlikely, but seek immediate medical attention if it occurs. Symptoms of a serious allergic reaction may include: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
The table shows adverse reactions occurring at an incidence of 1% or greater in relatively short-duration, placebo-controlled clinical trials of Doral. Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in actual practice.

A double-blind, controlled sleep laboratory study (N=30) in elderly patients compared the effects of quazepam 7.5 mg and 15 mg to that of placebo over a period of 7 days. Both the 7.5 mg and 15 mg doses appeared to be well tolerated. Caution must be used in interpreting this data due to the small size of the study.
