Dosage and Directions
VOLMAX tablets must be swallowed whole with a glass of water
and not chewed or crushed.
One 8 mg tablet twice daily or two 4 mg tablets twice daily.
As there may be adverse effects associated with excessive
dosing, the dosage or frequency of administration should only be
increased on medical advice.
VOLMAX tablets may cause a fine tremor of skeletal muscle,
usually the hands are most obviously affected.
Feelings of tension may occur also due to the effects on
skeletal muscle and not to direct CNS stimulation.
Peripheral vasodilatation and an increase in heart rate may
occur. Headaches may occur.
Hypersensitivity reactions including angioedema, urticaria,
bronchospasm, hypotension and collapse have been reported.
VOLMAX tablets and non-selective beta-blocking drugs, such as
propranolol, should not usually be prescribed together.
VOLMAX tablets should be administered cautiously to patients
suffering from thyrotoxicosis.
The effects of VOLMAX may be enhanced by concommitant
administration of aminophylline.
Potentially serious hypokalaemia may result from
beta2-agonist therapy mainly from parenteral and nebulised
administration. Particular caution is advised in acute severe
asthma as this effect may be potentiated by concomitant
treatment with xanthine derivatives, steroids, diuretics and by
hypoxia. It is recommended that serum potassium levels are
monitored in such situations.
In asthmatic patients whose condition deteriorates despite
VOLMAX therapy, the dosage should not merely be increased, but
alternative or additional therapy should be considered. Safety
during pregnancy and lactation has not been established. Known
