What is Loniten?

Loniten tablets contain minoxidil which is a powerful drug for lowering the blood pressure. It works by relaxing and enlarging certain small blood vessels so that blood flows through them more easily.

Who Should Take Loniten?

There are many people with high blood pressure, but most of them do not need Loniten. Loniten is used only when your doctor decides that:

  1. Your high blood pressure is severe;

  2. Your high blood pressure is causing symptoms or damage of vital organs and

  3. Other medicines did not work well enough or had very disturbing side effects.

Loniten should be taken only when a doctor prescribes it. Never give any of your Loniten tablets, or any other high blood pressure medicine, to a friend or a relative.


In some cases, doctors may prescribe Loniten for women who are pregnant or who are planning to have children. However, its safe use in pregnancy has not been established. If you are pregnant or are planning to become pregnant, be sure to tell your doctor.

How to Take Loniten?

Usually, your doctor will prescribe two other medicines along with Loniten. These will help lower blood pressure and will help prevent undesired effects of Loniten.

Often when a medicine like Loniten lowers blood pressure, your body tries to return the blood pressure to the original, higher level. It does this by holding on to water and salt (so there will be more fluid to pump) and by making your heart beat faster.

To prevent this, your doctor will usually prescribe a water tablet to remove the extra salt and water from your body and another medicine to slow your heartbeat.

You must follow your doctor's instructions exactly, taking all the prescribed medicines, in the right amounts, each day. These medicines will decrease the side effects you might otherwise have and will also help keep your blood pressure down.

You may take Loniten with water or with other liquids, either with or between meals. Loniten tablets come in two strengths (2½ mg and 10 mg) that are marked on each tablet. Pay close attention to the tablet markings to be sure you are taking the correct strength. Your doctor may prescribe half a tablet; the tablets are scored (partly cut on one side) so that you can easily break them.

When you first start taking Loniten, your doctor may need to see you often in order to adjust your dosage. Take all your medicine according to the schedule prescribed by your doctor. Do not skip any doses. If you should forget a dose of Loniten, wait until it is time for your next dose, then continue with your regular schedule. Remember, do not stop taking Loniten, or any of your other high blood pressure medicines, without checking with your doctor. Make sure that any doctor treating or examining you knows that you are taking high blood pressure medicines, including Loniten.

Warning Signals

Even if you take all your medicines correctly, you may have side effects. If any of the following warning signals occur, you must call your doctor immediately as your treatment may have to be adjusted.

  1. Increase in heart rate: You should measure your heart rate by counting your pulse rate while you are resting. If you have an increase of 20 beats or more per minute over your normal pulse, contact your doctor. Ask your doctor how often to check your pulse.

  2. Weight Gain: You should weigh yourself daily. If you quickly gain 5 or more pounds (2 or more kg), or if there is any swelling or puffiness in the face, hands, ankles, or stomach area, this could be a sign that you are retaining body fluids and you should call your doctor. A smaller weight gain (2 or 3 pounds or 1 to 1.5 kg) often occurs when treatment is started. You may lose this extra weight with continued treatment

  3. Also call your physician if you notice:

    1. increased difficulty in breathing, especially when lying down,

    2. new or worsening of pain in the chest, arm or shoulder or signs of severe indigestion and

    3. dizziness, lightheadedness or fainting.
