When This Medicine Should Not Be Used:

You should not use this medicine if you have had an allergic reaction to minoxidil, or if you have pheochromocytoma (a tumor that produces adrenalin) or a sudden or patchy hair loss. Do not use this medicine if you have no family history of hair loss, if you do not know the reason for your hair loss, or if you are currently using other medicines on your scalp. Do not use the foam if you have frontal baldness or receding hairline.

How to Use This Medicine:

Foam, Liquid

  • Your doctor will tell you how much medicine to use. Do not use more than directed.
  • Using more medicine than your doctor has prescribed will not speed up hair growth and may increase your risk of side effects.
  • Follow the instructions on the medicine label if you are using this medicine without a prescription.
  • Use only the brand of medicine your doctor prescribed. Other brands may not work the same way.
  • It is important to carefully follow the instructions for applying this medicine. This medicine is for use on the scalp only. Do not use this medicine on other parts of your body.
  • Hair growth usually occurs after this medicine has been used for several months. However, you will need to continue using this medicine to have hair growth. Hair loss will begin again within a few months after minoxidil treatment is stopped.
  • Wash your hair and make sure your hair and scalp are completely dry before putting on minoxidil.
  • When you are using the minoxidil foam, hold the can upside down and press the nozzle to release the foam into your fingers. The total amount of the foam you use each time should not be more than half a capful.
  • Apply minoxidil to the center of the bald area and spread it in a thin layer. Use only the applicator that came with your medicine.
  • Wash your hands with soap and water after putting minoxidil on your scalp.
  • If you accidentally get the medicine in your eyes, nose, or mouth, wash the area thoroughly with water. If using the pump spray, be careful not to breathe in the mist.
  • Do not use a hair dryer to dry your scalp after putting on minoxidil.
  • If you use minoxidil at bedtime, do not lie down for at least 30 minutes after putting on the medicine.
  • Do not use the foam near heat or open flame, or while smoking. Do not puncture, break, or burn the aerosol can.

If a dose is missed:

  • Apply a dose as soon as you can. If it is almost time for your next dose, wait until then and apply a regular dose. Do not apply extra medicine to make up for a missed dose.
