COLONIAL HEIGHTS, VA (WWBT) - Dr. John Clay is warning people about what to look out for when it comes to over the counter cold medications.
Cold and allergy products can be helpful, but like any medication, there are some risks.
Many over the counter products have a combination of several active medications included. Combining multiple products can result in double dosing of certain medications that could reach toxic levels.
Check the back of the box for the active ingredients. If two products contain the same ingredient, in most cases, they should not be taken simultaneously unless you've discussed it with your doctor.
