Before Using This Medicine

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

Allergies - Tell your doctor if you have ever had any unusual or allergic reaction to minoxidil or propylene glycol (nonactive product in medicine). Also tell your health care professional if you are allergic to any other substances, such as preservatives or dyes.

Pregnancy - Topical minoxidil has not been studied in pregnant women. However, some studies in animals have shown that minoxidil, when given by mouth, causes problems during pregnancy, although the studies have not shown that the medicine causes birth defects. Before using this medicine, make sure your doctor knows if you are pregnant or if you may become pregnant.

Breast-feeding - It is not known whether topical minoxidil passes into breast milk. However, minoxidil, taken by mouth, does pass into breast milk. Minoxidil is not recommended during breast-feeding, because it may cause problems in nursing babies.

Children - Studies of this medicine have been done only in adult patients, and there is no specific information comparing use of topical minoxidil in children up to 18 years of age with use in other age groups. Use in infants and children is not recommended. If you think your child has hair loss, discuss it with the doctor.

Older adults - This medicine has been tested in a limited number of older patients up to 65 years of age and has not been shown to cause different side effects or problems in this age group than it does in younger adults. However, studies have shown that the medicine works best in younger patients who have a short history of hair loss. Minoxidil has not been studied in patients older than 65 years of age.

Other 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. When you are using topical minoxidil, it is especially important that your health care professional know if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine or if you are using any of the following on your scalp:

• Corticosteroids (cortisone-like medicines) or
• Petrolatum (e.g., Vaseline) or
• Tretinoin (e.g., Retin-A) - Use of these products on your scalp may cause too much topical minoxidil to be absorbed into the body and may increase the chance of side effects

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

• Any other skin problems or an irritation or a sunburn on the scalp - The condition may cause too much topical minoxidil to be absorbed into the body and may increase the chance of side effects

• Heart disease or
• Hypertension (high blood pressure) - Topical minoxidil has not been studied in patients who have these conditions, but more serious problems may develop for these patients if they use more medicine than is recommended over a large area and too much minoxidil is absorbed into the body
