Before taking Diphenidol

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

There is no specific information comparing use of diphenidol for dizziness in children with use in other age groups. Also, there is no specific information about the use of diphenidol for nausea and vomiting in children who weigh less than 22.8 kilograms (50 pounds).

Geriatric

Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults or if they cause different side effects or problems in older people. There is no specific information comparing use of diphenidol in the elderly with use in other age groups.

Breast Feeding

There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Interactions with Medicines

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.

Interactions with Food/Tobacco/Alcohol

Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.

How to use Diphenidol

If you are taking diphenidol to prevent nausea and vomiting, it may be taken with food or a glass of water or milk to lessen stomach irritation, unless otherwise directed by your doctor. However, if you are already suffering from nausea and vomiting, it is best to keep the stomach empty, and this medicine should be taken only with a small amount of water.

Take this medicine only as directed. Do not take more of it and do not take it more often than directed by your doctor. To do so may increase the chance of side effects.
