What is the best medication to treat a cold?

Time: There's no known cure for the common cold. Paracetamol may help pain. Vitamin C is controversial. Antibiotics don't help as I'd viral. With time the body fights back.

Cold : Cold is caused by virus and there is no treatment for it . Rest , drinking hot fluids like soup and rest help with symptoms.

Symptom relief: There is no cure for the common cold, but there are meds that may make the symptoms a little more bearable. These include over-the-counter pain and fever relievers, nasal sprays, and cough medications. If you have several medical conditions, take prescription medications, or treating a young child, check with your doctor before taking OTC medications. http://www.healthline.com/health/cold-flu

Flu: I would start with rest fluids and treat your symptoms. If you have a fever take paracetamol and cooling measures. If you have muscle aches take ibuprofen. If you have a runny nose take a decongestant and consider an anti-histamine. Take an anti-nausea medication if you feel sick. High dose vitamin C and garlic are thought to have some immune boosting properties.
