When to Call the Doctor About Flu
If you just came down with miserable flu symptoms, you may wonder when to call the doctor. Sooner is better than later in case your doctor thinks you would benefit from flu medications that can help shorten the duration of the flu.
What Are Common Flu Symptoms?
The first challenge is determining if you have flu symptoms. If you have these symptoms, give your doctor a call. Common symptoms of the flu include:
In addition, if you've had the flu for a few days and then get worse, call your doctor immediately. These symptoms may indicate a secondary or bacterial infection with flu. Call your doctor if:
If you have a chronic medical condition such as heart disease, asthma, COPD, diabetes, or HIV/AIDS, it's important to call your doctor when the first flu symptoms appear as flu might increase the risk of serious problems associated with your chronic condition. For instance, if you have asthma and flu, you may need to boost your asthma medications and asthma inhalers to prevent an asthma attack. Your doctor can instruct you.
Also, seek emergency medical help if you or a loved one is extremely short of breath or has a severe headache or stiff neck.
What Flu Tests Will My Doctor Use?
Most of the time, a flu diagnosis is made by the person's symptoms. In some cases, your doctor may also run flu tests to make an accurate flu diagnosis. These tests usually involve taking a swab from your mouth and culturing this to identify the flu virus. Rapid flu tests may give your doctor results in about five to 30 minutes. Your doctor may prefer to use a rapid flu test before prescribing flu drugs, which must be taken within 48 hours of the first flu symptoms.
What Antiviral Drugs Will My Doctor Prescribe for the Flu?
Tamiflu and Relenza must be given within 48 hours of the onset of flu symptoms. These flu drugs can decrease the duration of the flu by one day if used within this early time period. They are usually given for about five days.
Your doctor will determine if you can take antiviral drugs with a flu diagnosis, but you need to call your doctor as soon as you have flu symptoms for these drugs to provide a benefit.
