I have 2 questions, is the strength of asmanex 110 comparable to Flovent 110. Is Flovent diskus small enough to get into the small airways. Vs HFA?

I have 2 questions, is the strength of asmanex 110 comparable to Flovent 110. Is Flovent diskus small enough to get into the small airways. Vs HFA?

No and Yes: Though asmanex and flovent are both steroids (cortisone) they do differ in strength. . This does not necessarily make one better than the other. Both agents are designed to get into the lungs to reduce inflammation. Remember, this type of "controller" must be used regularly- not like your "rescue inhaler" which is used only when you are having an attack. ...Read more

Please help! what is the maximum recommended dose of adrenaline that can be used on a patient taking halothane anaesthesia?

Halothane/EPI: Halothane is rarely used anymore - perhaps in some under-developed countries. Halothane is known to sensitize the heart muscle to the arrhythmogenic effects of drugs such as epinephrine. I am not aware of any studies (human) stating specifically the maximum recommended dose. It is best to not expose a patient to halothane. ...Read more

Is busesonide .5 inhalation form the same as the formulation for a nasoneb?    What is the advantage of delivering steroid with nasoneb vs qnasal form

Delivery system: You may mean Nasonex (mometasone) and qnasal. These are steroid medicines designed to be sprayed nasally and work locally not systemically. The nebulized Budesonide is inhaled into the lungs, work there but can get delivered into the mouth and wherever it passes thru and should work via the receptors in the airways.The nose sprays are a choice of the pt, and use the ones they feel better with. ...Read more

Why anti cough medications are oral, when its action is in the airways?

Why anti cough medications are oral, when its action is in the airways?

Absorption.: Medications are absorbed from the mouth and gut. Most enter the blood stream and act. That's why you take antibiotics by mouth when you have a bladder infection instead of putting them in the bladder. Most cough suppressants are not appropriate for acute cough. An inhaler to relax the bronchioles, or fight inflammation in your lungs is, sometimes. OTC cough, and cold meds are worthless. ...Read more

What is the maximum dose of albuterol that can be taken ina day? Are 6 puffs too much?

Not necessarily: If albuterol is needed to control your shortness of breath / cough, then use it (not 6 puffs at a time though - use as instructed by your doctor). However, if you are using albuterol frequently (e.g. Almost every day or several times each week), then you may need a maintenance medication for your breathing. (albuterol is short-acting). Treat underlying allergy issue. Please see your doctor. ...Read more

In adult onset primary hypersomnia, is it reasonable to take beta blockers if effective in contolling the high pulse side effect of methylphenidate?

In adult onset primary hypersomnia, is it reasonable to take beta blockers if effective in contolling the  high pulse side effect of methylphenidate?

Not exactly.: Beta-blockers are helpful for a variety of medical disorders, but like many medications are not entirely benign. Side effects include daytime fatigue and sleep disruption. What you have described is not a clear indication for beta blocker therapy - risk may outweigh benefit. Please consult with a local sleep specialist for further information. ...Read more

Can I use one metered dose inhaler to administer fluticasone and albuterol, one at a time? Or should I get separate inhalers?

Separate: Since each MDI device is customized to the unique product, I don't know any study showing that they can be interchanged. If you have lost one of them and it is an emergency, by all means go ahead. However ideally, one should not use a part devised for one device on another unless otherwise specified ( for example - Aerochambers) ...Read more

Smoking related?: You may have asthma, and/or be affected by your smoking. First, try quitting smoking and see if that makes a difference. You can also see your primary care provider or a lung specialist and have a test called spirometry, which can measure your lung capacity and make a diagnosis of asthma, if that is what you have. ...Read more

Accidentally blew inside the symbicort inhaler. When I do my dose next will it affect it or increase it if some is left inside ?

No. You're okay!: I assume you mean you discharged it without meaning to. Or you exhaled instead of inhaled. The particles deposit within seconds and are no longer in the chamber unless you have a spacer attached. Even then, the particles only stay suspended in the chamber for a few minutes. ...Read more

My Proair albuterol inhaler just reached zero on the dose counter. There is medicine left, can I still use it?

Maybe: It might be that when you reach ZERO on the counter, there is a little bit left, but not a reliable amount per puff. Therefore, when an inhaler is needed, if one has a new one, use the new one. If one has no new one, using the old one would be better than using nothing. One can get a refill when the pharmacy opens. ...Read more

No matter how, many home nebulizer treatments I do or doses off my rescue inhaler i still have had breathing difficulty last week, ER or my internist?

ER: It sounds like the Er is the safest place for you. When your usual medications and rescue medications don't work, you need a close evaluation of your oxygen levels as well as a look at blood work and your lungs. You may need intravenous medicines as well. Most doctors offices are not equipped for this and if you are seriously ill the ER is the best place. ...Read more
