Contraindications of Serevent:
If you have a history of asthma, it is imperative to consult a doctor. The doctor will go through your medical history and even do some tests to understand the gravity of the situation. After the doctor has completed his tests, he would also like to know if you have liver disease, epilepsy, heart disease, diabetes, seizure disorder, thyroid disorder, food or drug allergy or high blood pressure. You should not use this medicine if you are allergic to the medicine or the milk proteins. The doctor will only prescribe this medicine if they judge that the benefit is greater than the risks involved. This medicine can cause QT prolongation, which can rarely have fatal consequences. This medicine can interact with other medicines, especially, diuretics, which can increase the risk of QT prolongation. If you are using any prescription, non-prescription, herbal or other supplements, do let the doctor know immediately. Older people are at a higher risk and more sensitive to this medicine. In rare instances, this medicine can induce paradoxical worsening of bronchospasm which can be life-threatening. If this happens, stop using the medicine and consult the doctor.

In case, you are using this medicine, make sure that you inform your doctor if you are pregnant or plan to become pregnant. It is not confirmed yet if the medicine passes into the breast milk, hence caution should be exercised in case of nursing mothers.
Weather and Asthma
Weather conditions be it heat, cold, thunderstorm or rain, can lead to asthma attack. Take a look at the ways to manage these weather- related asthma attacks.
Like allergens and pollutants, weather changes can also cause asthma attack. Stanley Fineman, MD, MBA who is an allergist with Atlanta Allergy and Asthma Clinic says that, in asthmatics, the airways get hyper- reactive to certain allergens like pollens and irritants like perfume. Temperature changes, humidity and many other weather conditions also tend to irritate the airways. Change in temperature can lead to irritation of the airways. This depends from person to person. Some people do not face any problem. Their nose controls humidity without any difficulty while, some people who have allergies or asthma, who breathe through mouth face problems as pollutants, irritants and pollens cause trouble. IN people who are suffering from asthma, the airways are already inflamed. The susceptibility to disturbance with weather change is more in patients with severe asthma.
Weather conditions that trigger asthma
Here are some common weather conditions that trigger asthma symptoms and exacerbate them:
Cold air: Cold air is a sure asthma trigger. Fineman says that it predisposes asthmatics to more symptoms. Todd Rambasek who is MD, an adult and paediatric allergist at ENT and Allergy Health Services, Cleveland, Ohio says cold air leads to constriction of the airways leading to serious problem.
Wind and rain: Rainfall increases mold spores and wind blows pollen as well as mold.
Heat: In summers, increased ozone due to exhaust fumes, pollutants and smog exacerbates asthma symptoms.
Lightning: Thunderstorm generates ozone and can lead to exaggerated asthma symptoms.
Air pressure fluctuations: Barometric pressure causes sinus episodes. Sinusitis triggers asthma symptoms, quoted Dr. Rambasek.
How to manage these weather- related triggers?
The symptoms of weather- related asthma can be managed the same way as general asthma is managed. The first thing that you need to do is to determine the trigger. You should know if the trigger is pollen, rainstorm or heat. After you find out the trigger, you need to avoid them and control the exposure, quoted Fineman.
The triggers vary from person to person. For different people the trigger is different. Rambasek says that if your trigger for asthma attack is lightning storm, stay inside. If the attack occurs due to cold air, cover your face with a face mask or with a scarf; you can also use albuterol. If summer gives your asthma a trouble time, stay in an air conditioned room.
Monitor weather forecast using email, text or other online services. Also keep a tab on the forecast for humidity, ozone, air pressure and rain. Also, take your weather- triggered asthma medications on time. Using controller meds regularly will help you to manage asthma by leaps and bounds, says Rambasek.
You cannot control weather but, surely you can limit the attacks. You can reduce the frequency or intensity of attacks. All you need to do is to identify the weather trigger and then avoid it and learn to manage it.
