diphenhydramine HCl Uses (Generic)
Diphenhydramine Uses
Diphenhydramine is an over-the-counter antihistamine that is used to treat symptoms like red, irritated, itchy, watery eyes, sneezing, and runny nose related to the common cold, hay fever, and other respiratory allergies. Diphenhydramine may also be used to relieve cough caused by minor throat irritation. It is also used to prevent and treat motion sickness, and insomnia. Sometimes, diphenhydramine is prescribed to treat abnormal movements in people with early stages of Parkinson’s disease.
There may be other uses of diphenhydramine —your doctor or pharmacist can give you further drug information.
Diphenhydramine Mechanism of Action
Diphenhydramine works by blocking the action of a certain natural substance in the body called histamine that causes allergy symptoms.
Diphenhydramine Doses
Diphenhydramine is available as 25 mg and 50 mg tablets, and 12.5 mg/5 mL liquid. The usual dose of diphenhydramine in adults and children 12 years of age and older is 25 mg to 50 mg every 4-6 hours as needed. The diphenhydramine dose in children between 6 and 11 years of age is 12.5 mg to 25 mg every 4-6 hours as needed. Children younger than 6 years of age should not receive diphenhydramine without a doctor’s approval.
diphenhydramine HCl Directions (Generic)
How To Use Diphenhydramine
Diphenhydramine comes in the form of a tablet, liquid, and other dosage forms to be taken by mouth. The tablets are usually taken every 4-6 hours as needed.
Read the package label and follow the dosing instructions carefully. Do not take more diphenhydramine or take it more frequently than indicated on the package.
Measure liquid forms of the medicine using a dose-measuring cup or spoon to ensure the correct dose. Do not use a household spoon. Do not freeze liquid forms of diphenhydramine.
Remember that diphenhydramine is present in many combination products used to relieve symptoms of allergies, cough and cold. Check the labels of your over-the-counter medicines before using two or more products together. Make sure you do not exceed the maximum recommended dose of diphenhydramine.
Diphenhydramine can cause serious side effects, including death, in young children. Exercise caution when giving this medicine to children between 6 and 12 years of age. Do not give it to children under 6 years of age unless specifically directed by your child’s doctor. Never give over-the-counter cough and cold remedies meant for adults to children.
Diphenhydramine will provide symptomatic relief but will not cure your condition. If you do not get relief from allergy or cold symptoms after taking diphenhydramine for 7 days, contact your health care professional.
Missed dose: Diphenhydramine is usually taken when needed. If you miss a dose, take it as soon as you remember. However, if it is almost time for the next dose, skip the missed dose and take the next dose according to your regular dosing schedule. Do not take two doses together to make up for a missed one.
Storage: Store at room temperature (between 15-30° C or 59-86° F) away from moisture, heat, and direct light in a tightly closed container. Do not store medications in the bathroom where they can be exposed to moisture and heat. Keep all medications safely out of reach of children and pets.
Unused medicine: Unused diphenhydramine should be disposed of in a way that children, other people, and pets cannot consume them. Do not flush medications down the toilet. The best way to properly discard expired or unneeded medications is through a drug take-back program or through your local waste disposal company. Learn more about proper medication disposal.
NOTE: This medication guide is a summary and may not contain all possible diphenhydramine drug information. The information contained here may not be up-to-date. This sheet is for information purposes only. If you have further questions, talk to your health professional or pharmacist to ensure you receive proper medical advice, diagnosis, and treatment.

Diphenhydramine Risks, Warnings, and Complications
Pharbedryl (diphenhydramine) can cause serious symptoms in certain groups of people. Ask a doctor or pharmacist about other treatment options for allergy symptoms if you are at high risk of complications from diphenhydramine use.
|
Precautions Before Starting Diphenhydramine
Tell your healthcare professional if you have ever had an allergic reaction to diphenhydramine, any of the active or inactive ingredients in diphenhydramine products, or any other drugs.
Give your healthcare professional a complete medical history. Diphenhydramine may not be right for people with certain medical conditions such as asthma, emphysema, chronic bronchitis, glaucoma (high pressure in the eye), ulcers, low sodium, prostate enlargement, difficulty urinating, heart disease, high blood pressure, overactive thyroid, or seizures.
Give your health care professional a complete list of all your medicines, including prescription drugs, nonprescription drugs, vitamins, supplements, and herbal products. This can help avoid possible drug interactions.
If you are an older adult (age 65 years and above), talk to your doctor about other safer treatment options. Diphenhydramine is only given to older adults for serious allergic reactions.
Tell your doctor if you are pregnant, could be pregnant, are planning a pregnancy or are breastfeeding. The drug passes into breast milk and can potentially affect the infant.
Precautions During Use of Diphenhydramine
Tell all your doctors you are on Pharbedryl (diphenhydramine) before any surgery, including dental procedures. Keep your regular medical and laboratory appointments. Tell laboratory personnel that you are on diphenhydramine, as this medicine can lead to false test results on certain laboratory tests.
Contact your doctor if you become pregnant while taking diphenhydramine.
Diphenhydramine can make you drowsy and dizzy and affect your ability to focus. Do not drive, operate machinery or do anything else that requires your full attention until you know how this medicine affects you. Remember that drinking alcohol can make such symptoms worse.
Keep in mind that diphenhydramine will help relieve your symptoms but will not cure your condition. If you continue having symptoms after 7 days of taking diphenhydramine, contact your healthcare provider.
Diphenhydramine Drug Interactions
Diphenhydramine can have possible interactions with other drugs. This can affect how well the medications work. Interactions between diphenhydramine and other medicines can also increase the risk of severe adverse effects.
Give your doctor or pharmacist a complete list of your medications, including prescription drugs, nonprescription (over-the-counter) drugs, dietary supplements, and herbal products. Also, tell your healthcare provider if you smoke, drink alcohol, or use recreational drugs because some of these substances can cause serious health complications when used with prescription medicines.
