Symptomatic

Treatments that may help with symptoms include pain medication and medications for fevers such as ibuprofen and acetaminophen (paracetamol). However, it is not clear whether acetaminophen helps with symptoms. It is not known if over-the-counter cough medications are effective for treating an acute cough. Cough medicines are not recommended for use in children due to a lack of evidence supporting effectiveness and the potential for harm. In 2009, Canada restricted the use of over-the-counter cough and cold medication in children six years and under due to concerns regarding risks and unproven benefits. The misuse of dextromethorphan (an over-the-counter cough medicine) has led to its ban in a number of countries. Intranasal corticosteroids have not been found to be useful.

In adults, short term use of nasal decongestants may have a small benefit. Antihistamines may improve symptoms in the first day or two; however, there is no longer-term benefit and they have adverse effects such as drowsiness. Other decongestants such as pseudoephedrine appear effective in adults. Combined oral analgesics, antihistaminics, and decongestants are generally effective for older children and adults. Ipratropium nasal spray may reduce the symptoms of a runny nose but has little effect on stuffiness. Ipratropium may also help with coughs in adults. The safety and effectiveness of nasal decongestant use in children is unclear.

Due to lack of studies, it is not known whether increased fluid intake improves symptoms or shortens respiratory illness. As of 2017, heated and humidified air, such as via RhinoTherm, is of unclear benefit. One study has found chest vapor rub to provide some relief of nocturnal cough, congestion, and sleep difficulty.

Some experts advise against physical exercise if there are symptoms such as fever, widespread muscle aches or fatigue. It is regarded as safe to perform moderate exercise if the symptoms are confined to the head, including runny nose, nasal congestion, sneezing, or a minor sore throat. There is a popular belief that having a hot drink can help with cold symptoms, but evidence to support this is very limited.
