Why is this medication prescribed?

Unisom is not typically prescribed in the formal sense as a prescription medication. It is an over-the-counter (OTC) sleep aid that contains an antihistamine, usually diphenhydramine or doxylamine. While these antihistamines are primarily used to treat allergies, they also have sedative effects, which can help with sleep.

People may use Unisom or similar OTC sleep aids for short-term relief from insomnia or difficulty falling asleep. The sedative properties of the antihistamines in Unisom can induce drowsiness and promote sleep. However, it’s important to note that the use of Unisom or any sleep aid should be temporary, and if sleep problems persist, consulting with a healthcare professional is advisable.

How should this medicine be used?

Unisom is an over-the-counter sleep aid that typically contains the active ingredient diphenhydramine or doxylamine. The specific instructions for use may vary depending on the formulation and brand, so it’s crucial to read and follow the label instructions provided by the manufacturer. However, here are general guidelines for using Unisom:

• Dosage: The recommended dosage may vary, but for many formulations, the standard adult dose is one tablet (25 mg) taken about 30 minutes before bedtime. Do not exceed the recommended dosage unless directed by a healthcare professional.
• Administration: Take Unisom with a full glass of water. It is usually taken orally.
• Timing: Take Unisom about 30 minutes before you plan to go to sleep.
• Precautions: Avoid taking Unisom with alcohol or other medications that can cause drowsiness, as this may increase the risk of excessive sedation. Do not drive or engage in activities that require alertness immediately after taking Unisom, as it may cause drowsiness.
• Duration of Use: Unisom is generally recommended for short-term use. If sleep problems persist, consult with a healthcare professional.
• Special Populations: Pregnant and breastfeeding women should consult with a healthcare provider before using Unisom. Individuals with certain medical conditions (e.g., respiratory issues, glaucoma, urinary retention) should inform their healthcare provider before using Unisom.

Always follow the specific instructions provided on the packaging and consult with a healthcare professional if you have any concerns or questions about the appropriate use of Unisom. If sleep difficulties persist or worsen, seek medical advice rather than continuing to rely solely on over-the-counter sleep aids.
