When you’re sick, you just want fast relief. Your head hurts, your nose is stuffy, you’re coughing, and you can’t sleep. Standing in the pharmacy aisle, it’s tempting to grab a box that says “cold and flu multi-symptom relief” and be done with it.
But here’s what most people don’t realize: multi-symptom OTC products often contain unnecessary medications you don’t need—and sometimes those extras can cause more problems than they solve.
1. Hidden Overlap of Ingredients
Many products contain the same drugs in different combinations—acetaminophen for pain and fever, dextromethorphan for cough, pseudoephedrine or phenylephrine for congestion. If you take two products, you may double your dose without realizing it, which can be unsafe.
2.Treating Symptoms You Don’t Even Have
For example, if you only have nasal congestion but grab a “multi-symptom” box, you might be taking unnecessary cough suppressants, antihistamines, or fever reducers. These extra ingredients won’t help you, and they increase the chance of side effects like drowsiness, dry mouth, or elevated blood pressure.
3. Increased Side Effects
More ingredients mean more risk. Some multi-symptom meds contain stimulants that can keep you up at night or raise your heart rate, while others can cause grogginess when you need to be alert.
For example, if your only problem is a stuffy nose, a single decongestant is usually enough. If you’re just dealing with a cough, a cough suppressant can be used on its own. This way, you’re not adding extra medications that have no benefit for your situation.
Next time you’re sick, try this method:
Reassess often. If your symptoms change, you can adjust which medication you take—without layering drugs you don’t need.

National Diabetes Awareness Week
Diabetes affects the body’s ability to get energy from glucose. People with this condition are either not able to produce sufficient insulin (Type 1) or are unable to use the insulin their body makes to its full potential (Type 2).
When either of these things occurs, an excess of sugar remains in the blood. Left unchecked, too much sugar in the bloodstream can lead to the development of serious problems like kidney and heart disease, as well as vision loss. Unfortunately, 20% of people with diabetes may never know they have it.

Feedback from our amazing patients!
"I can’t believe I did not know about this kind of service! This was absolutely perfect for my health concern and they were able to provide me with the necessary medication and with such cinch. Completely recommended this service. For minor health concerns, this can save you an unnecessary and costly trip to an urgent care center."
"Amazing!! Easy and fast! I didn’t have to take my 4 year old into an urgent care where only god knows what germs are there. The doctor sent the script right to my pharmacy within minutes!!!"
"I would give 10 stars if I could! CallonDoc is literally the reason I am recovering instead of suffering as I write this. I was skeptical at first, but I’m not kidding when I tell you I got prescribed my antibiotics and picked it up at the pharmacy within 2 hours. So instead of waiting & paying around 300$...I paid 40$!! I’m very pleased."
