The dosage should be adjusted individually. If possible small doses are given first because it has often been shown that anti-allergic drugs are effective in comparatively small dosage. PHENVIT may be administered intramuscularly or intravenously. The onset of action depends on the mode of administration. Mostly there is an immediate effect on intravenous administration; on intramuscular administration, it takes about 10-20 minutes for the effect to set on. Injection may be repeated after 8-12 hours, if necessary.
