Generic Name: sotalol hydrochloride
Product Name: Solavert

Indication: What Solavert is used for

This medicine is used to treat arrhythmias, which is a problem when the heart beats too quickly or with the wrong rhythm.

Your doctor will have explained why you are being treated with this medicine and told you what dose to take.

Solavert is only available with a doctor’s prescription.

There is no evidence that this medicine is addictive.

Action: How Solavert works

Solavert contains sotalol hydrochloride, which belongs to the family of drugs known as beta-blockers. It slows down and steadies the heartbeat, reducing the effort the heart has to put into pumping blood.

Sotalol is a non-selective beta-adrenergic receptor blocker without sympathomimetic activity or membrane stabilising activity. It causes a decrease in heart rate and a limited reduction in the force of contraction of the heart. There is a reduction in cardiac work and in myocardial oxygen demand. Sotalol does not decrease blood pressure in normotensive subjects.  Its major effects are prolongation of the atrial, ventricular and accessory pathway effective refractory periods. The effect on the ventricular myocardium may be reflected by a lengthening of the QTc interval on electrocardiographic recordings. Like most other beta-blockers, sotalol inhibits renin release. This suppressive effect is significant both at rest and during exercise.

Solavert 80 mg tablets contain 80mg sotalol hydrochloride per tablet. Solavert 160 mg tablets contain 160mg sotalol hydrochloride per tablet.

The tablets also contain microcrystalline cellulose, magnesium stearate, maize starch, lactose (anhydrous), stearic acid, colloidal anhydrous silica, indigo carmine (CI 73015).

  • Make sure your doctor knows what other medicines you are already taking including ones you have bought yourself at the chemist or supermarket;
  • In particular, remind your doctor if you have asthma, bronchitis or any allergies such as hay fever, food allergies or are allergic to bee or wasp stings;
  • Make sure your doctor is aware of any kind of heart disease, diabetes, phaeochromocytoma, kidney disease or thyroid disease that you have or have had, or if you have been told that your pulse is slow or irregular;

Be careful driving or operating machinery until you know how Solavert affects you. As with other medicines, it may cause dizziness, light-headedness or drowsiness in some people. If this occurs do not drive or operate machinery or undertake any other activity that could be dangerous if you are dizzy, lightheaded or drowsy.

Taking other medicines

Some medicines can affect the way Solavert works. You should always tell your doctor about any other medicines you take, even those bought without a doctor’s prescription.

It is especially important that you tell your doctor if you are taking any of the following:

  • Medicines which lower blood pressure (including other beta-blockers);
  • Any other medicine used to treat an irregular heart rhythm or beat;
  • Digoxin, a medicine used for heart failure;
  • Medicines used to treat angina or other heart conditions;
  • Antidepressants (medicines used to treat depression);
  • Insulin or other drugs used to control diabetes;
  • Medicines used to control or prevent asthma (inhalers or tablets) or to control allergies or which are used for other lung problems;
  • Antihistamine medicines including terfenadine and astemizole that may be used to treat hayfever, allergies or to relieve symptoms of colds and flu;
  • Quinolone antibiotics (medicines used to treat infections);
  • Diuretics (water tablets);
  • Some medicines used during surgery or emergency situations, such as anaesthetics.

If you are not sure whether you are taking any of these medicines, check with your doctor or pharmacist.

How to take it

Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained here.

If you do not understand the instructions on the box, ask your doctor or pharmacist for help.

How much to take

Your doctor will decide on the dose for you, and they may need to change the dose a few times to get the best level for you.

The usual dose is 80mg to 160mg twice a day. Your doctor may need to increase this as very few patients may need up to three to four 160mg tablets spread over a day. The dosage may need to be different if you have a kidney problem.

How to take it

You should take your tablets with water one to two hours before meals. Do not take them with milk or meals.

How long to take it for

If you have been prescribed Solavert tablets, you must be sure to follow your doctor’s instructions very carefully.

Do not stop taking Solavert tablets suddenly, the dose needs to be reduced gradually over 7 to 14 days.

If you forget to take it

It is important not to miss a dose but if you do, take your next dose at the normal time and with the normal amount.

If you take too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much Solavert. Do this even if there are no signs of discomfort or poisoning. You may need medical attention.

Too much of this medicine will cause your blood pressure and heart rate to drop to dangerous levels. Serious heart problems may develop and this could be fatal.

While you are taking it

Things you must do

If you become pregnant while taking Solavert, tell your doctor. Your doctor can discuss with you the risks of taking it while you are pregnant.

If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking Solavert.

Tell any other doctor, dentist or pharmacist, who treats you that you are taking this medicine.

Things you must not do

Do not give your medicine to anyone else, even if they have the same condition as you.

Do not take this medicine to treat any other complaints unless your doctor tells you to.

Do not let yourself run out of tablets over weekends or on holidays.

After taking it


Store your tablets safely in a cool dry place. Protect from light and moisture. Do not store them or any other medicine in the bathroom or near a sink. Do not leave it in the car on hot days or on window sills. Heat and dampness can destroy some medicines.

Keep your tablets in the original blister pack they are provided in until it is time to take them. If you take the tablets out of the blister pack they will not keep well.

Keep all medicines out of the reach of children. A locked cupboard at least one-and-a-half meters above the ground is a good place to store medicines.

Schedule of Solavert

Solavert is a Schedule 4 (prescription only) medicine.

Side effects of Solavert

Rarely, serious heart problems can develop while you are taking normal doses but you must remember that you are taking this medicine because your heart already has a serious problem. It is very important that your doctor keeps a check on your progress.
