I have heard that desensitising injections can be very effective in treating hay fever. However, they are used in specialist hospital clinics with patients who have severe allergic reactions to things like bee and wasp stings. They are sometimes used in patients with hay fever who are unresponsive to more conventional treatments. Talk to your doctor for more information about this treatment. Research shows that people's hay fever symptoms tend to be at their worst during their mid-twenties.
Many people find that by the time they reach their mid-forties, hay fever is no longer a problem.
I seem to have hay fever symptoms all year round, but it gets worse in summer along with my asthma. Pollen is also a common trigger for asthma symptoms, which is why your asthma seems to get worse in the summer. There are many effective treatments for hay fever and allergic perennial rhinitis which can be used in addition to your usual asthma treatment. When allergic rhinitis is treated properly, it can help improve your asthma symptoms. It may also help to adjust your asthma treatment 2-4 weeks before the hay fever season to stop your asthma symptoms getting worse.
