This is a summary and does NOT have all possible information about this product. This information does not assure that this product is safe, effective, or appropriate for you. This information is not individual medical advice and does not substitute for the advice of your health care professional.

Nonsteroidal anti-inflammatory drugs (including naproxen) may rarely increase the risk for a heart attack or stroke. This effect can happen at any time while taking this drug but is more likely if you take it for a long time. The risk may be greater if you have heart disease or increased risk for heart disease (for example, due to smoking, family history of heart disease, or conditions such as high blood pressure or diabetes). Do not take this drug right before or after heart bypass surgery (CABG).
This drug may rarely cause serious (rarely fatal) bleeding from the stomach or intestines. This effect can occur without warning at any time while taking this drug. Older adults may be at higher risk for this effect.
Stop taking this medication and get medical help right away if you notice any of these rare but serious side effects: black/tarry stools, persistent stomach/abdominal pain, vomit that looks like coffee grounds, chest/jaw/left arm pain, shortness of breath, unusual sweating, confusion, weakness on one side of the body, slurred speech, sudden vision changes.
Talk to your doctor or pharmacist about the benefits and risks of taking this drug.
This product is a combination of 2 drugs: naproxen and diphenhydramine. It is used by adults who have trouble sleeping (insomnia) due to minor aches and pain.
Naproxen belongs to a group of drugs known as nonsteroidal anti-inflammatory drugs (NSAIDs). It is used to relieve minor aches and pain from various conditions such as headache, muscle aches, dental pain, menstrual cramps, or arthritis. It works by blocking your body's production of certain natural substances that cause inflammation. This effect helps to decrease swelling, pain, or fever. Diphenhydramine is an antihistamine used in this combination product to help you relax and fall asleep.
If you are also treating a chronic condition such as arthritis, ask your doctor about non-drug treatments and/or using other medications to treat your pain. See also Warning section.

Kidney problems can sometimes occur with the use of NSAID medications, including naproxen.

Drink plenty of fluids as directed by your doctor to prevent dehydration and tell your doctor right away if you have a change in the amount of urine.
This drug may make you dizzy or drowsy or blur your vision. Alcohol or marijuana (cannabis) can make you more dizzy or drowsy. Do not drive, use machinery, or do anything that needs alertness or clear vision until you can do it safely. Talk to your doctor if you are using marijuana (cannabis).
This medicine may cause stomach bleeding. Daily use of alcohol and tobacco, especially when combined with this medicine, may increase your risk for stomach bleeding. Limit alcoholic beverages and stop smoking. Consult your doctor or pharmacist for more information.
This medication may make you more sensitive to the sun. Limit your time in the sun. Avoid tanning booths and sunlamps. Use sunscreen and wear protective clothing when outdoors. Tell your doctor right away if you get sunburned or have skin blisters/redness.
Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).
Older adults may be more sensitive to the side effects of this drug, especially drowsiness, dizziness, confusion, kidney problems, stomach/intestinal bleeding or trouble urinating. Drowsiness, dizziness, and confusion can increase the risk of falling.
Before using this medication, women of childbearing age should talk with their doctor(s) about the benefits and risks (such as miscarriage, trouble getting pregnant). Tell your doctor if you are pregnant or if you plan to become pregnant. During pregnancy, this medication should be used only when clearly needed. It is not recommended for use during the first and last trimesters of pregnancy due to possible harm to the unborn baby and interference with normal labor/delivery.
This drug passes into breast milk and may have undesirable effects on a nursing infant. Consult your doctor before breast-feeding.
Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.
Some products that may interact with this drug include:
- ACE inhibitors (such as captopril, lisinopril)
- angiotensin II receptor blockers (such as losartan, valsartan)
- antihistamines applied to the skin (such as diphenhydramine cream, ointment, spray)
- corticosteroids (such as prednisone)
- "water pills" (diuretics such as furosemide)
This medication may increase the risk of bleeding when taken with other drugs that also may cause bleeding. Examples include anti-platelet drugs such as clopidogrel, "blood thinners" such as dabigatran/enoxaparin/warfarin, among others.
Tell your doctor or pharmacist if you are taking other products that cause drowsiness such as opioid pain or cough relievers (such as codeine, hydrocodone), alcohol, marijuana (cannabis), drugs for sleep or anxiety (such as alprazolam, lorazepam, zolpidem), muscle relaxants (such as carisoprodol, cyclobenzaprine), or other antihistamines (such as cetirizine, chlorpheniramine).
Check the labels on all your medicines (such as allergy or cough-and-cold products) because they may contain ingredients that cause drowsiness. Ask your pharmacist about using those products safely.
Check all prescription and nonprescription medicine labels carefully since many medications contain pain relievers/fever reducers (aspirin, NSAIDs such as celecoxib, ibuprofen, or ketorolac). These drugs are similar to naproxen and may increase your risk of side effects if taken together. However, if your doctor has directed you to take low-dose aspirin to prevent heart attack or stroke (usually at dosages of 81-325 milligrams a day), you should continue taking the aspirin unless your doctor instructs you otherwise. Daily use of naproxen may decrease aspirin's ability to prevent heart attack/stroke. Talk with your doctor about the risks and benefits. Ask about other medications that can be used to treat pain/fever.
This medication may interfere with certain laboratory tests (including allergy skin test), possibly causing false test results. Make sure laboratory personnel and all your doctors know you use this drug.
If someone has overdosed and has serious symptoms such as passing out or trouble breathing, call 911. Otherwise, call a poison control center right away. US residents can call their local poison control center at 1-800-222-1222. Canada residents can call a provincial poison control center. Symptoms of overdose may include: severe stomach pain, extreme drowsiness, seizures.
Laboratory and/or medical tests (such as blood pressure, complete blood count, liver/kidney function) may be performed periodically to monitor your progress or check for side effects. Consult your doctor for more details.
Keep all regular medical and laboratory appointments.
If you have arthritis, lifestyle changes (such as weight loss if needed, strengthening/conditioning exercises) may help improve your flexibility and joint function. Consult your doctor for specific instructions.
Store at room temperature away from light and moisture. Do not store in the bathroom. Keep all medications away from children and pets.
