The critical difference in Unisom formulations
Before addressing the safety of taking two 50 mg tablets, it is essential to clarify that Unisom is not a single product. The brand offers several different over-the-counter sleep aids, each containing a different active ingredient and different dosage instructions. The active ingredient determines the proper dosage and the risks associated with an overdose.
- Unisom SleepTabs (Doxylamine Succinate): Each tablet contains doxylamine succinate. The recommended dosage for this product is typically one tablet at bedtime. Taking two of these tablets would exceed the labeled recommendation.
- Unisom SleepGels or Extra Strength (Diphenhydramine HCl): These products contain diphenhydramine hydrochloride per dose. For these formulations, the recommended dosage is one capsule or tablet, taken a certain time before bedtime. In this case, taking two would mean ingesting an amount that far exceeds the maximum recommended single dose.
The significant risk of exceeding the dosage
Regardless of the formulation, doubling the labeled maximum dosage for any Unisom product is unsafe and significantly increases the risk of side effects and overdose. The body's ability to process and eliminate medication is not linear; exceeding the recommended dose can lead to toxic levels of the active ingredient in the body, which can be dangerous or even fatal.
Overdose symptoms can include:
- Excessive drowsiness and dizziness
- Confusion, disorientation, and hallucinations
- Agitation and restlessness
- Dry mouth and nose
- Enlarged pupils and blurred vision
- Rapid or irregular heartbeat
- Difficulty urinating
- Seizures
These severe anticholinergic effects demonstrate why strict adherence to packaging instructions is critical. For individuals, particularly the elderly, who are more sensitive to these side effects, even a small increase in dosage can lead to significant harm.
Understanding the correct dosage
To ensure safe use, always read the product label carefully and understand the active ingredient. The following guidelines apply to Unisom's common oral products for adults and children 12 and over:
- Unisom SleepTabs (Doxylamine): The typical dosage is 1 tablet before bedtime.
- Unisom SleepGels (Diphenhydramine): The typical dosage is 1 capsule before bedtime.
- Unisom Extra Strength (Diphenhydramine): The typical dosage is 1 tablet before bedtime.
Comparison of Unisom Formulations
To help clarify the differences between Unisom products, the following table compares key details:
| Feature | Unisom SleepTabs | Unisom SleepGels / Extra Strength |
|---|---|---|
| Active Ingredient | Doxylamine Succinate | Diphenhydramine HCl |
| Typical Tablet/Capsule Strength | Varies by product | Varies by product |
| Recommended Single Dose | Typically 1 tablet | Typically 1 capsule/tablet |
| Maximum Daily Dose | Varies by product | Varies by product |
| Primary Pharmacological Class | Antihistamine / Hypnotic | Antihistamine / Hypnotic |
| Overdose Potential | High when exceeding recommended dose | High when exceeding recommended dose |
What to do in case of accidental overdose
If you or someone you know has accidentally taken more than the recommended dose of Unisom, immediate action is crucial. Even if the individual is not showing any noticeable symptoms, it is important to contact a healthcare professional immediately.
Steps to take:
- Call a poison control center immediately by dialing 1-800-222-1222 (in the U.S.). They are available 24/7 and can provide expert guidance based on the dosage and individual circumstances.
- If the individual exhibits severe or life-threatening symptoms, such as seizures, extreme confusion, or difficulty breathing, call 911 or go to the nearest emergency room immediately.
Safely managing your sleeplessness
For individuals with chronic insomnia lasting more than two weeks, relying on over-the-counter sleep aids is not a safe long-term solution. Prolonged sleep issues can be a symptom of a more serious underlying medical condition and should be evaluated by a healthcare provider.
Alternative strategies to improve sleep hygiene include:
- Maintaining a consistent sleep schedule, even on weekends.
- Creating a relaxing bedtime routine to signal to your body that it's time to sleep.
- Ensuring your bedroom is dark, quiet, and cool.
- Avoiding caffeine, alcohol, and heavy meals close to bedtime.
- Incorporating regular exercise into your daily routine, but not too close to sleep.
- Consider cognitive behavioral therapy for insomnia (CBT-I), a proven therapeutic approach.

Conclusion
It is unsafe to take two Unisom 50 mg sleep tabs. The labeling for Unisom products provides clear guidance about the maximum dosage, which is typically one tablet or capsule per night for standard formulations. Exceeding the recommended dose, regardless of the product's strength, increases the risk of severe side effects, including excessive sedation, confusion, and serious heart complications. For persistent sleeplessness, always prioritize a consultation with a healthcare professional to identify and treat the root cause safely.
