Unisom - Diphenhydramine

What is it?

Composition

Unisom tablets contain the active substance diphenhydramine hydrochloride, which provides the main effect of the drug. Diphenhydramine is a first-generation antihistamine with sedative properties. Due to this, Unisom helps reduce nervous tension and facilitates the process of falling asleep.

The drug also includes auxiliary components that ensure the stability, shape and shelf life of the tablets:

• Microcrystalline cellulose
• Corn starch
• Magnesium stearate
• Dextrose

These ingredients do not have a direct effect on sleep, but they are important for maintaining the structure and quality of the drug.

How to use?

To achieve the best effect from using Unisom, it is important to follow the recommendations for its use. The tablets should be taken orally with a sufficient amount of water, approximately 30 minutes before the expected sleep time. This time is necessary for the active substance to begin to act, facilitating rapid sleep.

It is recommended to follow these steps:

1. Take one tablet before bedtime. Do not exceed the recommended dose.
2. Use the drug only when necessary. Unisom is intended for short-term use, do not use it for more than two weeks without consulting a doctor.
3. Do not combine Unisom with alcohol or other sedatives, as this may increase the sedative effect and lead to undesirable consequences.

If you forget to take a tablet or your sleep pattern changes, do not increase the dose next time. In case of prolonged sleep problems, it is recommended to consult a doctor.

How does it work?

Unisom works by containing diphenhydramine, a first-generation antihistamine. In the body, it blocks histamine receptors, which are usually involved in allergic reactions. However, diphenhydramine also has a strong sedative effect, making it an effective remedy for insomnia.

When you take Unisom, diphenhydramine crosses the blood-brain barrier into the brain and begins to affect the central nervous system, causing a feeling of drowsiness. This allows you to quickly relax and fall asleep. This mechanism of action makes Unisom useful for those who have difficulty falling asleep due to stress, anxiety, or other temporary factors that interfere with normal sleep.

It is important to note that diphenhydramine acts for a limited time, providing a soft and natural sleep, allowing you to wake up without feeling very sluggish in the morning.

Indications

Unisom is intended for the short-term treatment of sleep disorders. It is recommended in cases where sleep problems arise due to temporary factors or stressful situations. The drug may be useful for people who have difficulty falling asleep or suffer from frequent night awakenings.

The main indications for the use of Unisom include:

• Insomnia associated with nervous tension or stress
• Difficulty falling asleep
• Sleep disorders caused by temporary changes in the regime (for example, changing time zones)
• Frequent awakenings during the night

Unisom can also be used for temporary relief of these conditions in situations where it is necessary to quickly restore a normal sleep pattern.

Contraindications

Despite its effectiveness, Unisom is not suitable for everyone and has certain contraindications. The drug should be used with caution or completely avoided in some cases. Before starting to use, it is recommended to consult a doctor, especially if you have chronic diseases.

Unisom is contraindicated in the following cases:

• Allergy or hypersensitivity to diphenhydramine or any of the components of the drug
• Closed-angle glaucoma
• Prostate diseases accompanied by difficulty urinating
• Severe heart and vascular diseases
• Bronchial asthma or other chronic respiratory diseases

Also, Unisom is not recommended for use during pregnancy and breastfeeding without consulting a doctor. In case of any chronic diseases, especially those related to the respiratory or cardiovascular system, it is necessary to carefully evaluate the potential risks and benefits before starting to use the drug.

Side effects

Although Unisom is considered safe for short-term use, it can cause side effects, especially if you exceed the recommended dosage or use it for a long time. Most side effects are related to the active substance, diphenhydramine, which, in addition to sedation, can have other effects on the body.

The most common side effects include:

• Daytime sleepiness
• Dizziness
• Dry mouth, nose, or throat
• Blurred vision
• Difficulty urinating

In rare cases, more serious reactions may occur, such as allergic reactions (rash, itching, swelling), heart problems, or severe dizziness. If you experience any unusual symptoms, stop taking the drug and consult a doctor. The use of Unisom is not recommended in combination with other sedatives or alcohol, as this may enhance the sedative effect and increase the risk of adverse reactions.
