For the average case of whooping cough there is no treatment likely to make a difference to the course of the illness or materially reduce the symptoms. It will generally take its course no matter what. Attempts to get benefit from bronchodilators, cough suppressants or antibiotics are generally futile.
There are a few exceptions however.
One exception is in those who get severe illness. This is most often infants, particularly those under 3 to 6 months, but it also applies to the frail or very elderly and those debilitated by other illness or malnutrition. In such cases treatment with steroids can reduce the severity and antibiotics might be used to prevent complicating infections. Supportive measures with hydration and oxygenation may be necessary. Such cases would obviously be in hospital. It should be noted that in the developed world one would not expect even 1% of cases to require hospitalization because most cases are mild.
Another exception is when serious complications occur. This is also rare and probably affects about 1 or 2% of cases in the developed world. The most frequent complication is pneumonia which requires standard antibiotic treatment. Some patients get a secondary infection of bacterial tracheo-bronchitis causing increased cough and sputum which may improve with antibiotics, but does not generally cause illness.
For very young babies whooping cough is a dangerous illness and they can die from pneumonia, respiratory failure and encephalopathy. It is to protect babies that we have an immunization program, and it is effective. Many people with whooping cough are given an antibiotic such as azithromycin. This is to kill any Bordetella pertussis they may still carry so as to make it more difficult to pass it on to others. It does not help the disease because the bugs have already done the damage by the time it is usually diagnosed. If however you have such an antibiotic while you are incubating the disease it is believed it may prevent it developing.
The UK authoritative body, the Institute for Health and Clinical Care Excellence (NICE), has published a Clinical Knowledge Summary on whooping cough. It is directed at health care professionals to provide them with the best evidence based information about managing this disease. Some may find this of interest. I have the utmost respect for this body and have no disagreement with their recommendations. http://cks.nice.org.uk/whooping-cough
When there is no effective treatment what remains to be done is management. For babies and children this will be mainly comforting during an attack and reassurance that it will soon pass and they will be fine. Back patting is not going to help but holding and stroking might. If vomiting occurs it is good to be leaning forward or face down if reclining so vomitus falls away from the lungs.
Babies who vomit may need refeeding and so might older children. It is common for children to lose weight with whooping cough and is more serious for babies.
Babies should not be left alone when they have whooping cough, even at night, so that problems do not go undetected. This also applies to older children until they can indicate they don't want that, by which point they should be out of any danger.
It should be standard practice for sufferers to be checked by a doctor at least once. Even if it is not diagnosed, a cough that bad need a doctor's examination. A competant doctor will arrange for some investigation of blood, or nasal, or oral fluid if the doctor suspects whooping cough. It is a notifiable disease and effort should be made by the doctor to confirm it. You cannot expect a doctor to test for it if it is not suspected to be the cause. Which test is done will depend on the service available to the doctor.
Note again my advice to capture a paroxysm on your smartphone to assist your doctor with diagnosis.
Sufferers should be removed from the presence of other people when they have an attack of coughing or they should remove themselves. Adults generally do that anyway. This is to reduce transmission. Going outside is even better.
Any general deterioration, particularly if it includes fever or breathlessness needs a medical check for complications such as pneumonia.
Women may well find they leak urine during an attack. This can only be managed by using pads but will clear up when the whoopng cough has cleared.
It is vital to keep away from pregnant women in the last half of pregnancy and from children until they have had their primary shots, usually finished at about 4 months, unless you have been told you are no longer infectious.
