(minoxidil topical solution)

DIN (Drug Identification Number)

00708925 ROGAINE 20MG/ML TOPICAL SOLUTION

How does Rogaine work? What will it do for me?

Minoxidil belongs to a group of medications known as hair regrowth treatments. It is used to treat male pattern baldness. It is not meant for baldness due to nonhereditary factors (e.g., baldness caused by illnesses such as iron deficiency or medications such as cancer chemotherapy).

When applied to the scalp of a man with male pattern baldness, it often stimulates hair growth. The exact way it works is not known, but it is thought to improve the blood flow around the hair follicle and stimulate the hair follicle to grow hair. Minoxidil topical solution is not approved for use by women.

It usually takes 4 or more months of use for the medication to work. Hair may fall out when minoxidil is first used. This is a temporary effect of the medication. Once hair starts to grow, it will stay for as long as the medication is used. The hair will begin to fall out again a few months after the applications are stopped.

Your doctor may have suggested this medication for conditions other than the ones listed in these drug information articles. As well, some forms of this medication may not be used for all of the conditions discussed here. If you have not discussed this with your doctor or are not sure why you are using this medication, speak to your doctor. Do not stop using this medication without consulting your doctor.

Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to use this medication if their doctor has not prescribed it.

How should I use Rogaine?

The recommended dose is 1 mL applied twice daily to the scalp, starting in the center of the affected area. This dose should be used no matter how large the area to which it is being applied. The maximum daily dose is 2 mL.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way you are using the medication without consulting your doctor.

The solution comes with a pump-spray applicator, a rub-on applicator, an extended spray tip applicator, and a child-resistant dropper. The spray is more convenient for applying to large areas of the scalp, while the other applicators make it easier to use on small areas of the scalp or under hair. Refer to package directions for details on the best way to apply the solution with each dosage form.

It is important that the solution stay in contact with the scalp for at least 4 hours after application. During this time, avoid activities such as swimming, showering, or physical activity that may cause excessive perspiration.

If you are washing your hair before applying the medication, use a mild shampoo. To avoid eye irritation, wash your hands well after applying this medication to the scalp. Avoid inhaling the spray mist. Do not apply this medication to any area of the body other than the scalp.

It is important to use this medication exactly as prescribed by your doctor. If you miss a dose use it as soon as possible and continue with your regular schedule. If it is almost time for the next dose, skip the missed dose and continue with your regular dosing schedule. Do not use a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Store this medication at room temperature and keep it out of the reach of children.

Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.
