Allfen CD is a commonly prescribed medication used to treat symptoms of allergies, colds, and respiratory conditions. This medication contains a combination of an antihistamine and a decongestant, providing relief from nasal congestion, runny nose, sneezing, and itching.

The antihistamine component in Allfen CD works by blocking the effects of histamine, a substance in the body that causes allergy symptoms. This helps to reduce symptoms such as itching, sneezing, and watery eyes. The decongestant component works by narrowing the blood vessels in the nasal passages, which helps to reduce swelling and congestion.

It is important to follow the dosage instructions provided by your healthcare provider or pharmacist when taking Allfen CD. Taking more than the recommended dose can lead to serious side effects, including increased heart rate, high blood pressure, and difficulty sleeping.

Common side effects of Allfen CD may include drowsiness, dizziness, dry mouth, and blurred vision. If you experience any severe side effects such as chest pain, difficulty breathing, or a rapid heartbeat, seek medical attention immediately.

Before taking Allfen CD, be sure to inform your healthcare provider of any other medications you are taking, as well as any medical conditions you may have. This will help to ensure that Allfen CD is safe and appropriate for you to use.

Overall, Allfen CD can be an effective medication for providing relief from allergy and cold symptoms. However, it is important to use this medication as directed and to consult with your healthcare provider if you have any concerns or questions.
