Question: My 3.5 yr old son is having severe dry cough (no fever or cold) from almost a month.
All the doctors say it is allergic cough mainly due to cold. and have been prescribing the same meds with different names.
Ambrolite Levo; Ascoril LS+; levocytrizine/ montelucast; Budecort/ Levolin nebulizers; Azithromycin; Clarithromycin; Lupituss; zerotuss; Prednisolone/ Decazor

But all these meds have failed to stop the cough over this one month. The cough usually gets bad at morning; evening and makes him vomit (please note that i live at a cold place, but we keep him indoors in a very warm room and keep a steamer running as well).

Please suggest me some cough suppressent which can cure or ATLEAST relieve his cough. How much zerotuss/ lupituss and steroid (omnacotril/ decazor) can i give (currently 5 ml thrice a day, which does not help at all).
His X ray was also done which is also normal.

The patient profile got mixed up somehow. Please ignore the additional info section for medical history; known allergies and current meds. Instead consider the below please:

Medical History
occasional allergic cough throughout this year, mainly dry cough

Current Medications
clarithromycin; Zerotuss; Montelucast; Decazor; Budecort.

Known Allergies
cold air suspected to aggravate cough

Brief Answer:
Give him foracort /formonide /budamate Nebulization.

Detailed Answer:
Thanks for your question on Healthcare Magic.
I can understand your concern.
Best treatment of allergy is identification of allergen and if possible complete avoidance of it.
So get done allergy testing and avoid things allergic to him.
Instead of levolin, he should be given foracort nebulization because foracort /budamate /formonide is having combination of formoterol and budesonide.
Formoterol is better than levolin (levosalbutamol).
Also give CPM (chlorpheniramime maleat) and dextromethorphan syrup. Commonly available trade names are cheston CS, arodil D, Corex DX etc. These syrups are good cough suppressants and it has not been given earlier in his case.
Dose of zerotuss is enough for him. Don't give more than 5ml thrice a day.
Don't give omnacortil more.
Hope I have solved your query. I will be happy to help you further. Wishing good health to your son. Thanks.

I have been giving decazor bd 5 ml since 3 days and clarithromycin 5ml bd since 3 days.
Should I continue or stop both Meds and give only cough suppressants, nebulization and anti allergic.
I feel he has started coughing up mucus and has blocked nose as well. And he sweats profusely while coughing.
Please sugggest

Brief Answer:
Better to give mucolytic and expectorant drug.

Detailed Answer:
Thanks for your follow up question on Healthcare Magic.
I can understand your concern.
Since he is producing mucus, better to give mucolytic and expectorant drug.
So give ambrolite syrup. Don't give lupituss or zerotuss or other cough suppressants.
Continue Clarithomycin for 2 more days.
Taper down decazor syrup (don't stop all of a sudden).
Continue anti allergic and Nebulization (foracort).
Also start paracetamol (anti inflammatory) for sweating.
Hope I have solved your query. I will be happy to help you further. Wishing good health to your son. Thanks.

Yes, I have asthma, allergies, and lung issues/bronchitis and I'm trying to find a reasonable inhaler that doesn't cost an arm and a leg. My doctor has prescribed Proair and Avar, both are usually about 100.00 to 200.00 each. I can't afford this, even with insurance. I have been taking albuterol and formoterol fumarate, and wanted to find out if these were comparable to what the doctor has prescribed.

Hi I have developed allergic asthma at the age of 25. I never had a history of asthma in the past 24 years & no one from my family ever had this disease. My chest XRay is normal & the Ige count is 380 IU, I have been prescribed a combination of Fluticasone 200mcg & Formoterol 6mcg as I had some problem with Budesonide 200mcg & Formoterol 6mcg(Had Nose blockage & eye irritation after taking budesonide). This steriod + LABA combination is prescribed in powder format ie (Rotocaps). I developed this disease while I was posted at Mysore & than Bangalore for on an assignment & since than this disease dosen't seem to go away. I feel taking Montek LC 1/4 tablet gives me the best relief as compared to the above steriods but do feel quite drowsy after this medication though it is just 1/4 of the tablet. One of the doctors suggested me to go for an allergy test as I was a victim of Late Onset Asthma. I wanted to know if an allergy test will help me get rid of this disease. I have been doing breathing exercise & have recently started taking Lemon with hotwater as lemon acts as natural antihistamine.

Unfortunately I have an HMO which forced me to get a preferred provider in an urgent care center. I have only been seen by a young 25 year old PA. She prescribed to me Dulera as a daily preventive inhalant for once a day usage medicine for my recently diagnosed COPD condition

First of all is she qualified to digonose such a serious condition and secondly is Dulera the right medicine

I was prescribed Augmentin 3 times daily for 10 days for acute bronchitis. I am also using an steroid inhaler. I have been taking it for three and a half days now. I am still coughing up a lot of mucus and am having a lot of wheezing/rattling going on in my chest. I feel I am better than I was a day or two ago, but how long should it take get rid of this sickness? What are some signs that I am getting better??
