Uses for diphenidol
Diphenidol is used to relieve or prevent nausea, vomiting, and dizziness caused by certain medical problems.
Before using 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 diphenidol, the following should be considered:
Allergies
Tell your doctor if you have ever had any unusual or allergic reaction to diphenidol 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.
Pediatric
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.
Breastfeeding
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.
Other medical problems
The presence of other medical problems may affect the use of diphenidol. Make sure you tell your doctor if you have any other medical problems, especially:
- Enlarged prostate or
- Glaucoma or
- Intestinal blockage or
- Low blood pressure or
- Stomach ulcer—Diphenidol may make these conditions worse.
- Kidney disease or
- Urinary tract blockage—Higher blood levels of diphenidol may occur, increasing the chance of side effects.
Proper use of 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 diphenidol should be taken only with a small amount of water.
