Simply Sleep

Simply Sleep is an antihistamine that helps with sneezing, a runny nose, watery eyes, hives, skin rash, itching, and other cold or allergy symptoms.

Simply Sleep is also used to help with motion sickness, to help you sleep, and to treat some symptoms of Parkinson's disease. This sleep aid is not for children younger than 12 years old.

There are many brands and forms of diphenhydramine available. Not all brands are mentioned in this guide.

Simply Sleep may also be used for reasons not listed in this medication guide.

Use exactly as directed on the label, or as prescribed by your doctor. Simply Sleep is only for short-term use until your symptoms improve.

Taking too much Simply Sleep can lead to serious heart problems, seizures, coma, or death.

Always follow directions on the medicine label about giving Simply Sleep to a child. Do not use the medicine only to make a child sleepy. Death can occur from the misuse of antihistamines in very young children.

For motion sickness, take Simply Sleep 30 minutes before you will be in a situation that causes you motion sickness (such as a long car ride, airplane or boat travel, amusement park rides, etc). Continue taking this medicine with meals and at bedtime for the rest of the time you will be in a motion-sickness situation.

As a sleep aid, take Simply Sleep within 30 minutes before bedtime.

You must chew the chewable tablet before you swallow it.

Measure liquid medicine carefully. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).

Remove an orally disintegrating tablet from the package only when you are ready to take the medicine. Place the tablet in your mouth and allow it to dissolve, without chewing. Swallow several times as the tablet dissolves.

Call your doctor if the condition you are treating with Simply Sleep does not improve, or if you have a fever with a headache, cough, or skin rash.

Do not use Simply Sleep for longer than 2 weeks to treat sleep problems, or longer than 7 days to treat cold or allergy symptoms.

Simply Sleep can affect the results of allergy skin tests. Tell any doctor who treats you that you are using Simply Sleep.
