Cold and Cough Medicine for Infants and Children
The safety of giving infants and children over-the-counter (OTC) cold and cough medicine is important for caregivers to understand. While there is no "gold standard" recommendation for giving infants and children OTC cold and cough medicine for fever, aches, cough, and runny nose, a few standards have been recommended. The American Academy of Pediatrics recommends that OTC cold and cough medicine only be used in children age four years and older. The American College of Chest Physicians recommend that these medicines only be used in children age 15 years and older. The FDA recommends that OTC cold and cough medicine be used in children 2 years of age and older. However, there is agreement in regard to which OTC medications should not be used in children under the age of four (or the age of two, depending upon which guidelines are used), and they are 1) certain antihistamines like brompheniramine, chlorpheniramine maleate, and diphenhydramine (Benadryl); 2) cough expectorants (guaifenesin); 3) cough suppressants (dextromethorphan, DM); and 4) decongestants (pseudoephedrine and phenylephrine). Aspirin should never be given to infants, children, and adolescents due to the possibility of a rare, but often severe and even fatal illness called Reye's syndrome. REFERENCES:FDA.

Home remedies and over-the-counter (OTC) drugs used for the treatment of the signs and symptoms of colds and the flu may affect blood sugar levels in people with diabetes.Some medications are OK to take if you have diabetes get a cold or the flu include nonsteroidal anti-inflammatory drugs or NSAIDs, like acetaminophen (Tylenol) and ibuprofen (Motrin) to control symptoms of fever and pain. Most cough syrups are safe to take; however, check with your pediatrician to see what medications are safe to give your child if he or she has type 1 or 2 diabetes. If you have diabetes and are sick with a cold or flu, you need to check your blood sugar levels more frequently. Continue taking your regular medications. Eat a diabetic low-glycemic index diet rich in antioxidants. To prevent colds and the flu drink at least eight 8 ounce glasses of water a day. To replenish fluids, drink sports drinks like Gatorade and Pedialyte to replenish electrolytes. Avoid people who are sick, sneezing, coughing, or have other symptoms of a cold or flu.
Cold Agglutinin Disease
Cold agglutinin hemolytic anemia or cold agglutinin hemolytic disease, is rare disorder of the autoimmune system. There are two types of cold agglutinin disease, primary and secondary. Characteristics, symptoms, and signs of in cold agglutinin disease are premature destruction of red blood cells in the body’s natural defense antibodies. The lifespan of red blood cells is approximately 120 before the spleen destroys the antibodies. In cold agglutinin disease, the severity of the condition is determined by how long it takes for the red blood cells to survive, and at the rate that the bone marrow continues to produce more red cells. Immune hemolytic anemias are classified by the optimal temperature when the antibodies try to destroy red blood cells. Cold agglutinin anemia occurs at temperatures between 10 C (50 F) and 37 C (F 98.6) or above while the body warms antibody hemolytic anemia. Usually, cold agglutinin anemia becomes apparent between the ages of 50 to 60. Other symptoms of the disease include fatigue, jaundice (yellowing of the skin and eyes), fingers and/or toes are cold and sweat, an uneven bluish or reddish discoloration of the toes, ankles, and wrists (Raynaud's syndrome), and fingers. Usually, cold agglutinin anemia affects people that are older. The disease is diagnosed by a physical exam, and the Coomb's test. If the red blood cells destruction seem to be slowing on its own, treatment therapies, usually, isn’t needed. Other treatments for cold agglutinin anemia are corticosteroids, and splenectomy (removal of the spleen). There is no cure for cold agglutinin disease.

COVID-19 vs. Flu vs. Cold
When you're feeling sick, it can be difficult to distinguish the symptoms of a COVID-19 infection from the symptoms of the common cold or the flu (influenza). While fever is common with the flu and COVID-19, sneezing is typically only associated with colds. Though sore throats are typical with colds, they are uncommon with COVID-19 infections and the flu.
Cold vs. Flu
Though the common cold and flu share many signs and symptoms, they are caused by different viruses. Signs and symptoms include sneezing, sore throat, runny nose, fatigue, and cough. Treatment options for the cold and flu are similar and focus on reducing symptoms. Doctors may prescribe antivirals/neuraminidase inhibitors for the flu.
Sinus Infection vs. Cold
Viruses cause the common cold and most sinus infections. Bacterial and fungal infections may also cause a sinus infection. Signs and symptoms of colds and sinus infections include nasal irritation or dryness, sore throat, stuffy nose, nasal discharge/congestion, sneezing, and cough. Additional symptoms of sinus infections include sinus pressure behind the cheeks or eyes, facial pain when pressure is applied, bad breath, and thick yellow or green mucus. Treatment focuses on symptom relief.
What Can Trigger a Cold Sore?
After you get infected with HSV, it lies inactively in the nerve cells inside your skin and may appear as another cold sore at the same place as before.
How Can Teens Cope With A Cold?
Usually, teens have a healthy immune system to cope with common cold. Getting plenty of rest and drinking lots of fluids can ease the symptoms.
Emphysema, Chronic Bronchitis, and Colds
If you have a COPD such as emphysema, avoiding chronic bronchitis and colds is important to avoid a more severe respiratory infection such as pneumonia. Avoiding cigarette smoking, practice good hygeine, stay away from crowds, and alerting your healthcare provider if you have a sinus infection or cold or cough that becomes worse. Treatment options depend upon the severity of the emphysema, bronchitis, or cold combination.
