People with allergies suffer from multiple symptoms including sneezing, congestion, sinus headaches and itchy, watery eyes. Triggers of these symptoms include dust mites, pollen, cigarette smoke and animal dander. One popular drug for the treatment of allergies is Tylenol Severe Allergy. This medication contains a pain reliever and an antihistamine. In response to allergies, your body naturally produces histamine, which causes the symptoms of the allergy. An antihistamine counters the effects of histamine, and thus reduces the allergy symptoms. The antihistamine in Tylenol Severe Allergy is very effective at reducing the symptoms of allergies; however, there are side effects that should be considered when deciding on the treatment of allergies.
Ingredients
The active ingredients in Tylenol Severe Allergy are acetaminophen and diphenhydramine. Acetaminophen is the active ingredient in regular Tylenol and functions as a pain reliever and fever reducer. Tylenol Severe Allergy also contains an antihistamine, diphenhydramine, which is a popular drug for the treatment of allergy symptoms. Tylenol Severe Allergy contains 12.5 mg of diphenhydramine.
Side Effects
There are multiple side effects that are caused by the active ingredients in Tylenol Severe Allergy. The side effects of diphenhydramine include agitation, drowsiness and fatigue, dry mouth, dizziness, blurred vision and depression. In cases where more of the medication is taken than is recommended, other side effects may occur, which include shaking, fever, seizures, coma and possibly death.
Acetaminophen, the pain reliever of Tylenol, does not have any significant side effects. However, acetaminophen can cause liver damage if taken in excess. If you have taken an overdose of acetaminophen, you should seek treatment immediately and be aware that detrimental affects of the drug can occur even if you do not feel any signs or symptoms of overdose.
Diphenhydramine and Driving
Because drowsiness, fatigue and dizziness are side effects of Tylenol Severe Allergy, taking this medication and operating heavy machinery, such as driving a car, is not advised. In fact, results from a study headed by John M. Weiler, MD, indicate that diphenhydramine impairs a person's driving more than alcohol. Therefore, people should be very careful when taking Tylenol Severe Allergy and avoid driving whenever possible.
