What It Is and How It Works
Unisom
Unisom is an over-the-counter sleep aid that contains diphenhydramine, an antihistamine that blocks histamine receptors in the brain, which can induce a sedative effect. This makes it effective for helping individuals fall asleep.
Xanax
Xanax is a prescription medication under the class of benzodiazepines. It works by enhancing the effect of GABA, a neurotransmitter that inhibits activity in the brain, promoting relaxation and reducing anxiety. It is primarily used to treat anxiety disorders and panic attacks.
Indications / Uses
Unisom
Unisom is approved for short-term management of insomnia, particularly for those who have difficulty initiating sleep. It is not recommended for chronic insomnia or as an ongoing sleep aid.
Xanax
Xanax is indicated for the management of anxiety disorders, including generalized anxiety disorder (GAD) and panic disorder. It may be used off-label for other types of anxiety-related conditions under professional guidance.
Dosage Forms and Typical Dosing Considerations
Unisom
Unisom is commonly available in tablet form, with typical dosing being 25mg to 50mg taken at bedtime as needed. Individuals should follow the dosing guidance provided on the package or by a healthcare professional and not exceed recommended amounts.
Xanax
Xanax comes in immediate-release and extended-release tablets, with dosing tailored to the condition being treated, patient response, and tolerance. Dosing typically starts low to minimize side effects, and healthcare providers should adjust dosages based on patient needs.
Dosing considerations may include patient age, kidney function, presence of liver disease, or use of other CNS depressants. Professional advice is necessary for dosing decisions.
How to Take It Correctly Step-by-Step
When using Unisom:
- Take 30 minutes before you intend to sleep.
- Ensure you have a full night of sleep set aside to avoid daytime drowsiness.
- Avoid alcohol and other sedatives while using Unisom.
- Store in a cool, dry place away from children.
When using Xanax:
- Follow the prescription instructions carefully.
- Take it at the same time each day, with or without food.
- If you miss a dose, take it as soon as you remember but avoid doubling doses.
- Avoid alcohol and discuss the use of other medications with your provider.
- Store in a safe place due to the potential for abuse or misuse.
Side Effects Common to Serious
Common Side Effects
- Unisom: Drowsiness, dry mouth, headache

Contraindications & Precautions
Unisom: Should not be used in those with known allergies to diphenhydramine or similar drugs. Caution is advised in pregnant or breastfeeding women, and those with chronic respiratory issues or glaucoma.
Xanax: Should not be used in individuals with hypersensitivity to benzodiazepines. Use caution if there’s a history of substance misuse, depression, or respiratory issues. Avoid during pregnancy, especially the first trimester, due to teratogenic effects.
Both medications require cautious use in older adults due to increased sensitivity and risk of confusion or falls.
Drug, Food, and Supplement Interactions
Potential Interactions for Unisom: Alcohol and other sedatives can enhance drowsiness. Caution with medications like muscle relaxants.
Potential Interactions for Xanax: CNS depressants, including opioids and alcohol, can lead to severe sedation or respiratory impairment. Grapefruit can increase Xanax levels, leading to greater sedative effects.
Patients should inform their healthcare provider about all current medications, including prescription, over-the-counter medications, vitamins, and herbal supplements.
