Volmax tablets

How does it work?

Volmax tablets contain the active ingredient salbutamol, which is a type of medicine known as a short-acting beta 2 agonist. (NB. Salbutamol is also available without a brand name, ie as the generic medicine.)

Salbutamol works by acting on receptors in the lungs called beta 2 receptors. When salbutamol stimulates these receptors it causes the muscles in the airways to relax. This allows the airways to open.

In conditions where there is narrowing of the airways, such as asthma or chronic obstructive pulmonary disease (COPD, eg emphysema and chronic bronchitis), it is difficult for air to get in and out of the lungs. By opening the airways, salbutamol makes it easier to breathe.

Salbutamol is most commonly taken using an inhaler device. Inhaling the medicine allows it to act directly in the lungs where it is needed most. It also reduces the potential for side effects occurring in other parts of the body, as the amount absorbed into the blood through the lungs is lower than if it is taken by mouth.

Salbutamol when used as an inhaler is known as a reliever. This is because it works very quickly to relieve asthma attacks, wheezing, chest tightness or shortness of breath. Salbutamol inhalers can also be used to open the airways shortly before exercising to prevent wheezing.

Salbutamol is sometimes prescribed to be taken by mouth for people who cannot use inhalers very well. Volmax tablets are "controlled release tablets". This means they release the salbutamol slowly over 12 hours. The tablets are taken regularly twice a day, which helps keep the airways open all the time.

What is it used for?

Asthma

Chronic obstructive pulmonary disease

Warning!

Do not exceed the dose of salbutamol that your doctor has prescribed you to use.

If your salbutamol tablets don't seem to work as well as usual, or for as long as usual to relieve wheezing or chest tightness, you should consult your doctor as soon as possible. It may be that your asthma or COPD is getting worse and your doctor might need to give you another medicine.

People with severe asthma should have regular blood tests to monitor the amount of potassium in their blood. This is because low oxygen levels in the blood (hypoxia) and various asthma medicines, including this one, can lower blood potassium levels.

Not to be used in

Known sensitivity or allergy to any ingredient.

Volmax tablets are not recommended for children under three years of age.

This medicine should not be used if you are allergic to one or any of its ingredients. Please inform your doctor or pharmacist if you have previously experienced such an allergy. If you feel you have experienced an allergic reaction, stop using this medicine and inform your doctor or pharmacist immediately.

Pregnancy and Breastfeeding

Certain medicines should not be used during pregnancy or breastfeeding. However, other medicines may be safely used in pregnancy or breastfeeding providing the benefits to the mother outweigh the risks to the unborn baby. Always inform your doctor if you are pregnant or planning a pregnancy, before using any medicine.

It is important that asthma is well controlled in pregnant women. Wherever possible, asthma medications should be taken by inhaler, as this minimises the amount of medicine that enters the bloodstream and crosses the placenta. Seek medical advice from your doctor.

Salbutamol passes into breast milk in small amounts. The effect of this on the breastfed baby is unknown, therefore this medicine should be used with caution in breastfeeding mothers. In general, salbutamol inhalers can be used as normal during breastfeeding, because the amount of medicine that passes into the breast milk after using an inhaler is negligable and unlikely to harm the baby. Seek medical advice from your doctor.
