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 nylidrin, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to nylidrin 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.

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 nylidrin in the elderly with use in other age groups. However, nylidrin may reduce tolerance to cold temperatures in elderly patients.

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.

Other Medical Problems

The presence of other medical problems may affect the use of nylidrin. Make sure you tell your doctor if you have any other medical problems, especially:

• Angina (chest pain) or
• Fast heartbeat or
• Heart attack (recent) or other heart disease or
• Overactive thyroid gland or
• Stomach ulcer—May make these conditions worse.

Nylidrin may cause you to have a fast or pounding heartbeat. To keep this from affecting your sleep, do not take the last dose of the day at bedtime. Instead, it is best to plan your dose or doses according to a schedule that will least affect your sleep. Ask your health care professional to help you plan the best time to take nylidrin.

Dosing

The dose of nylidrin will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of nylidrin. If your dose is different, do not change it unless your doctor tells you to do so.

The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.

• For oral dosage form (tablets):
  • Adults: 3 to 12 milligrams (mg) three or four times a day.

Missed Dose

If you miss a dose of nylidrin, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double doses.

Storage

Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Keep from freezing.

Keep out of the reach of children.

Do not keep outdated medicine or medicine no longer needed.

It may take some time for nylidrin to work. If you feel that the medicine is not working, do not stop taking it on your own. Instead, check with your doctor.

The helpful effects of nylidrin may be decreased if you smoke. If you have any questions about this, check with your doctor.
