How to use Sons Duo
Finasteride
Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.
- The usual dose is one tablet each day.
- The tablets can be taken with or without food.
- Finasteride will not work faster or better if you take it more than once a day
Your doctor will help you to determine if Finasteride is working for you. It is important to take Finasteride for as long as your doctor prescribes it. Finasteride can only work over the long term if you continue taking it.
Full instructions can be found in the Sons Full Works product literature.
Minoxidil
Always use this medicine exactly as described in this leaflet or as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.
Your doctor will determine the suitable dose and length of treatment with Minoxidil 5% cutaneous solution.
Minoxidil 5% cutaneous solution is for cutaneous use only. Do not ingest. It should only be applied directly to the scalp area.
Do not apply to areas of the body other than the normal healthy scalp. It should not be used on inflamed, infected, irritated or painful scalp skin.
Daily dose for adult men aged 18-65 years
The recommended daily dose is 1 ml of solution twice daily (10 sprays from the dosage pump is equivalent to 1 ml of solution).
You must respect the recommended daily dose regardless of the extent of your hair loss.
- Wash hands thoroughly with water before application.
- The hair and scalp must be completely dry when applying the solution.
- Apply a 1 ml dose of solution (10 sprays from the dosage pump) to the total affected area of the scalp starting in the centre of the area being treated.
- The solution should be massaged lightly into the scalp using your fingertips.
- After using Minoxidil 5% cutaneous solution, wash hands thoroughly with plenty of water.
If the solution is accidentally applied to an area of the body other than the scalp, rinse thoroughly with plenty of water to avoid any unwanted hair growth
Continued use of Minoxidil 5% cutaneous solution
You may need to use this medicine twice daily for at least 2 months before you see new hair growth, this is because hair growth is a slow process.
Hair growth may be soft and downy at the start but should eventually become the same as normal hair.
When you stop using this medicine, the hair that has regrown may disappear after 3-4 months and the balding/hair loss process will continue. Continued use is necessary to increase and maintain hair re-growth, or hair loss will begin again
If you have no improvement in your hair growth after one year of use, you should discontinue treatment.
If at any time during your treatment you are concerned you should talk to your doctor or pharmacist.
Full instructions can be found in the Sons Full Works product literature.
