About Product

What Is Benadryl?

Benadryl is a non-drowsy antihistamine which is used to treat perennial and seasonal allergic rhinitis (including hay fever, dust mite allergies, and pet allergies).

It can also be used to treat allergic skin rashes (such as hives or urticaria).

Benadryl is available as a once-a-day tablet containing 10mg of cetirizine. It is suitable for adults and for children aged 12 or over.

You can buy Benadryl online from Prescription Doctor's trusted online pharmacy. We offer a next-day delivery on all orders approved before 3pm, Monday to Friday.


How Does Benadryl Work?

The active ingredient in Benadryl is cetirizine dihydrochloride, a non-drowsy (non-sedating) antihistamine. Benadryl prevents histamines from causing an allergic reaction within the body (the body produces histamines when it reacts to an allergen and the results include a runny nose, sneezing, itchy eyes, and rashes). The cetirizine within Benadryl blocks the histamine receptors and thus no allergic reaction can occur.


How Do I Take Benadryl?

For adults and children over 12, take one tablet once a day with a glass of water. Benadryl does not need to be taken on an empty stomach.

In order for Benadryl to be effective, it should be taken once your hay fever symptoms have begun, or if you anticipate them beginning in the near future.

If symptoms continue after taking Benadryl, seek advice from a pharmacist or doctor.


Side effects and cautions

Before taking any medication, whether bought over-the-counter or prescribed by a doctor, it's important to familiarise yourself with the information contained in the patient information leaflet enclosed with your medication.

Who Should Not Take Benadryl?

Most people can take Benadryl without any issues and it will work effectively. There are some groups of people who should avoid Benadryl and these include:

  • Children under 12
  • Patients on dialysis with severe kidney failure
  • People who are allergic to any of the ingredients within Benadryl

Who Should Get Medical Advice Before Using Benadryl?

It is always wise to speak to a medical professional before taking Benadryl if you are unsure. Those who should always seek medical advice before using Benadryl include:

  • Those with kidney problems – a lower dose may be recommended
  • Those with epilepsy
  • Pregnant and breastfeeding women

Benadryl And Other Medications

If you are prescribed histamine for any conditions such as leukaemia, taking Benadryl may have a negative effect since it reduces the effectiveness of histamines. Antihistamines such as Benadryl can also affect how well betahistine works, and should be avoided if possible.

Allergic reaction

If you are allergic to cetirizine dihydrochloride or any of the other ingredients listed on the packaging or patient information leaflet, do not take Benadryl.

If you experience an allergic reaction shortly after taking Benadryl one-a-day tablets, inform your doctor straight away or go directly to the nearest accident and emergency department.

Signs of allergic reaction include:

  • Chest tightening
  • Dry, red and cracked skin
  • Itchy, red watery eyes
  • Raised, itchy, red rash (hives)
  • Swelling of the lips, tongue, eyes or face
  • Tummy pain, nausea, vomiting or diarrhoea
  • Wheezing

Frequently asked questions

What should I do if I forget to take Benadryl when I should?

If you forget to take Benadryl, your allergic symptoms may persist. Take the correct dosage as soon as you remember. Do not take a double dose of Benadryl to make up for a missed dose – it should only be taken once every 24 hours.

If you accidentally take more Benadryl than you should, call 111 or contact your doctor immediately for advice.

Drinking alcohol while taking Benadryl can increase your risk of side effects such as dizziness, drowsiness and nausea.

For most people, Benadryl is unlikely to cause drowsiness. You should always ensure you know how this medication will affect you before carrying out any potentially hazardous activities including driving or operating machinery.
