1. What Minoxidil Tablets are and what they are used for

This medicine contains minoxidil, which is one of a group of medicines called 'vasodilators'. It can be used to treat very high blood pressure (hypertension) and works by relaxing blood vessels so that blood passes through them more easily. This helps to lower blood pressure.

You must talk to your doctor or pharmacist if you do not feel better or if you feel worse.

2. What you need to know before you take Minoxidil Tablets
Do not take Minoxidil Tablets
  • If you are allergic to minoxidil or any of the other ingredients of this medicine (listed in section 6).
  • If your high blood pressure is caused by hormones from a tumour (phaeochromocytoma), usually near the kidneys.

Warnings and Precautions

Talk to your doctor or pharmacist before using Minoxidil Tablets:

  • If you are pregnant or trying to become pregnant.
  • If you have heart failure (you may feel breathless, wheezy or tired and your ankles may swell up);
  • If you have ever had a heart attack.

Minoxidil Tablets encourage salt and water to remain in your body. Too much salt and water in the body can make you feel breathless, wheezy, sick and tired, and can stop Minoxidil Tablets working properly. Minoxidil Tablets also makes your heartbeat faster.

To avoid these problems, your doctor will prescribe two other medicines for you to take with Minoxidil Tablets. One will be a water tablet (diuretic) to help your body get rid of excess water, and the other a beta-blocker or similar medicine to stop your heart beating too fast or angina pain in the chest.

If your doctor gives you a low salt diet, follow it carefully. You should weigh yourself daily and keep an accurate record of your weight while you are taking this medicine. Tell your doctor if you put on more than 1 to 1.5kg. The cause could be extra fluid in your body. Tell your doctor if you think you have gained weight - even though it may not be due to the medicine. Your doctor will want to monitor fluid and salt (electrolyte) levels in your body.

You may recognise increased hair growth (hypertrichosis) after starting treatment, this usually emerges in the face but may subside with continued treatment. This side effect is reversible upon stopping treatment but may take one to six months.

Your doctor will want to make regular checks on your blood pressure and general health. You should also have occasional checks on your heart.

If you have an ECG test (to check the electrical activity of your heart) or any blood tests, remind your doctor that you are taking Minoxidil Tablets, as it can change the results.

Your doctor may monitor your blood for the very rare possibility of decreased white blood cells and platelets cells.

In some patients, inflammation of membrane around heart, fluid accumulation under the membrane around heart (cardiac tamponade) can occur. Your doctor should monitor these carefully and may try to drain the fluid or may consider stopping treatment with Minoxidil Tablets.

Patients with kidney failure and undergoing haemodialysis may need smaller doses of Minoxidil Tablets, which should be used with special care in these patients to maintain electrolyte balance in body.

Other medicines and Minoxidil Tablets

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines obtained without a prescription.

It is particularly important you tell your doctor about any other medicine you are taking to reduce your high blood pressure. These medicines may interact with Minoxidil Tablets by causing blood pressure to drop too low. In particular, tell your doctor if you are taking guanethidine or betanidine so you can be monitored whilst on treatment with Minoxidil Tablets or your doctor may consider stopping these therapies before starting treatment with Minoxidil Tablets.

Your doctor will tell you when and how to stop taking this medicine.

The dose can be increased to 20 mg and then 40 mg as single or divided doses if required for optimum blood pressure control. It is unusual to need more than 50 mg a day in adults and children aged over 12 years. In very rare instances your doctor can decide to use up to a maximum of 100 mg.


For adults over 65, the usual starting dose is 2.5 mg each day.

Use in children 12 years and under

For children of 12 and under, the dose depends on their weight but they should not be given more than 1 mg per kilogram of body weight each day. The starting dose is normally 0.2 mg each day for each kilogram of their weight.

During treatment with minoxidil the child should be under specialist supervision. The daily dose of minoxidil will be determined by the specialist and it may be adjusted according to the child's needs.

During treatment the child will be additionally treated with other medicines as decided by the specialist to prevent rapid heartbeat and accumulation of fluid in the body. You should contact the doctor if the child has any of the following: a very rapid heartbeat, rapid breathing, swelling of the legs, rapid weight gain, and reduced urine. While on treatment with minoxidil the child will need to be regularly seen by the doctor.
