Denavir


Pronunciation: pen-SEYE-kloe-veer
Generic Name: Penciclovir
Brand Name: Denavir


Denavir is used for:

Treating recurring cold sores associated with the herpes simplex virus. It may also be used for other conditions as determined by your doctor.


Denavir is an antiviral. It works by preventing the herpes simplex virus from growing.


Do NOT use Denavir if:


  • you are allergic to any ingredient in Denavir

Contact your doctor or health care provider right away if any of these apply to you.



Before using Denavir:


Some medical conditions may interact with Denavir. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:


  • if you are pregnant, planning to become pregnant, or are breast-feeding

  • if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement

  • if you have allergies to medicines, foods, or other substances

  • if you have a weakened immune system

Some MEDICINES MAY INTERACT with Denavir. Because little, if any, of Denavir is absorbed into the blood, the risk of it interacting with another medicine is low.


Ask your health care provider if Denavir may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.


How to use Denavir:


Use Denavir as directed by your doctor. Check the label on the medicine for exact dosing instructions.


  • Start treatment as soon as lesions or signs of cold sores (tingling, redness, itching, or a bump) appear.

  • Before using Denavir, wash your hands, clean your face, and pat dry.

  • Apply enough of Denavir to cover only the cold sore area of tingling (or other symptoms) before the cold sores appear. Rub the cream in until it disappears.

  • Wash your hands with soap and water immediately after using Denavir.

  • To clear up your infection completely, use Denavir for the full course of treatment. Keep using it even if your symptoms improve in a few days.

  • If you miss a dose of Denavir, use it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not use 2 doses at once.

Ask your health care provider any questions you may have about how to use Denavir.



Important safety information:


  • Use Denavir only on cold sores on the lips or face. Avoid applying in or near the eyes as irritation may occur.

  • Denavir is not a cure for cold sores and all patients may not respond to it, especially patients with weakened immune systems.

  • Denavir should not be used in CHILDREN younger than 12 years old; safety and effectiveness in these children have not been confirmed.

  • PREGNANCY and BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using Denavir while you are pregnant. It is not known if Denavir is found in breast milk. Do not breast-feed while taking Denavir.


Possible side effects of Denavir:


All medicines may cause side effects, but many people have no, or minor, side effects. Check with your doctor if any of these most COMMON side effects persist or become bothersome:



Bad taste in mouth; burning, pain, flushing, or itching at the application site; headache.



Seek medical attention right away if any of these SEVERE side effects occur:

Severe allergic reactions (rash; hives; itching; difficulty breathing; tightness in the chest; swelling of the mouth, face, lips, or tongue).



This is not a complete list of all side effects that may occur. If you have questions about side effects, contact your health care provider. Call your doctor for medical advice about side effects. To report side effects to the appropriate agency, please read the Guide to Reporting Problems to FDA.

If OVERDOSE is suspected:


Contact 1-800-222-1222 (the American Association of Poison Control Centers), your local poison control center, or emergency room immediately. Denavir may be harmful if swallowed.


Proper storage of Denavir:

Store Denavir at room temperature, between 68 and 77 degrees F (20 and 25 degrees C). Store away from heat, light, and moisture. Keep Denavir out of the reach of children and away from pets.


General information:


  • If you have any questions about Denavir, please talk with your doctor, pharmacist, or other health care provider.

  • Denavir is to be used only by the patient for whom it is prescribed. Do not share it with other people.

Robitussin Flu


Generic Name: acetaminophen, chlorpheniramine, dextromethorphan, and pseudoephedrine (a SEET a MIN oh fen, KLOR fen EER a meen, DEX troe meth OR fan, SOO doe ee FED rin)

Brand Names: Alka-Seltzer Plus Cough and Cold Liquigel, Children's Tylenol Flu, Comtrex Cold and Flu Maximum Strength Liquid, Comtrex Cold and Flu Maximum Strength Tablet, Robitussin Flu, Robitussin Honey Flu Nighttime, Theraflu (pseudoephedrine) Cold & Cough, Theraflu Flu & Cough, Theraflu Night Cough and Cold and Flu, Theraflu Nightime Maximum Strength, Theraflu Severe Cold & Congestion, Triaminic Cold and Fever, Triaminic Flu, Cough & Fever, Vicks 44 Cold, Flu and Cough, Vicks Formula 44M


What is Robitussin Flu (acetaminophen, chlorpheniramine, dextromethorphan, and pseudoephedrine)?

Acetaminophen is a pain reliever and fever reducer.


Chlorpheniramine is an antihistamine that reduces the natural chemical histamine in the body. Histamine can produce symptoms of sneezing, itching, watery eyes, and runny nose.


Dextromethorphan is a cough suppressant. It affects the signals in the brain that trigger cough reflex.


Pseudoephedrine is a decongestant that shrinks blood vessels in the nasal passages. Dilated blood vessels can cause nasal congestion (stuffy nose).


The combination of acetaminophen, chlorpheniramine, dextromethorphan, and pseudoephedrine is used to treat headache, fever, body aches, runny or stuffy nose, sneezing, itching, watery eyes, and sinus congestion caused by allergies, the common cold, or the flu.


Dextromethorphan will not treat a cough that is caused by smoking.

Acetaminophen, chlorpheniramine, dextromethorphan, and pseudoephedrine may also be used for purposes not listed in this medication guide.


What is the most important information I should know about this medication?


Do not take more of this medication than is recommended. An overdose of acetaminophen can damage your liver or cause death. Do not take this medication without a doctor's advice if you have ever had alcoholic liver disease (cirrhosis) or if you drink more than 3 alcoholic beverages per day. Do not use cold medicine if you have untreated or uncontrolled diseases such as glaucoma, asthma, emphysema, chronic bronchitis, high blood pressure, heart disease, coronary artery disease, or overactive thyroid. Avoid drinking alcohol. It may increase your risk of liver damage while taking acetaminophen. Do not use this medication if you have used an MAO inhibitor such as furazolidone (Furoxone), isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam, Zelapar), or tranylcypromine (Parnate) in the last 14 days. A dangerous drug interaction could occur, leading to serious side effects. Ask a doctor or pharmacist before using any other cold, allergy, pain, or sleep medication. Acetaminophen (sometimes abbreviated as APAP) is contained in many combination medicines. Taking certain products together can cause you to get too much acetaminophen which can lead to a fatal overdose.

What should I discuss with my healthcare provider before taking this medication?


Do not take this medication without a doctor's advice if you have ever had alcoholic liver disease (cirrhosis) or if you drink more than 3 alcoholic beverages per day. You may not be able to take medicine that contains acetaminophen. Do not use cold medicine if you have untreated or uncontrolled diseases such as glaucoma, asthma, emphysema, chronic bronchitis, high blood pressure, heart disease, coronary artery disease, or overactive thyroid. You should not use this medication if you have severe constipation, a blockage in your stomach or intestines, or if you are unable to urinate. Do not use a cold medicine if you have used an MAO inhibitor such as furazolidone (Furoxone), isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam, Zelapar), or tranylcypromine (Parnate) in the last 14 days. A dangerous drug interaction could occur, leading to serious side effects.

Ask a doctor or pharmacist if it is safe for you to take this medicine if you have:



  • liver disease, cirrhosis, or a history of alcoholism;




  • a blockage in your digestive tract (stomach or intestines);




  • diabetes;




  • kidney disease;




  • epilepsy or other seizure disorder;




  • cough with mucus, or cough caused by emphysema or chronic bronchitis;




  • enlarged prostate or urination problems;




  • pheochromocytoma (an adrenal gland tumor); or




  • if you take potassium (Cytra, Epiklor, K-Lyte, K-Phos, Kaon, Klor-Con, Polycitra, Urocit-K).




It is not known whether acetaminophen, chlorpheniramine, dextromethorphan, and pseudoephedrine will harm an unborn baby. Do not use cold medicine without medical advice if you are pregnant. This medication may pass into breast milk and may harm a nursing baby. Do not use cold medicine without medical advice if you are breast-feeding a baby.

How should I take Robitussin Flu (acetaminophen, chlorpheniramine, dextromethorphan, and pseudoephedrine)?


Use exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended. Cold medicine is usually taken only for a short time until your symptoms clear up.


Do not take more of this medication than is recommended. An overdose of acetaminophen can damage your liver or cause death.

Measure liquid medicine with a special dose-measuring spoon or medicine cup, not with a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one.


The chewable tablet must be chewed thoroughly before you swallow it.


Dissolve one packet of the powder in at least 4 ounces of water. Stir this mixture and drink all of it right away.


Do not give this medication to a child younger than 4 years old. Always ask a doctor before giving a cough or cold medicine to a child. Death can occur from the misuse of cough and cold medicines in very young children.

Do not take for longer than 7 days in a row. Stop taking the medicine and call your doctor if you still have a fever after 3 days of use, you still have pain after 7 days (or 5 days if treating a child), if your symptoms get worse, or if you have a skin rash, ongoing headache, or any redness or swelling.


If you need surgery or medical tests, tell the surgeon or doctor ahead of time if you have taken a cold medicine within the past few days. Store at room temperature away from moisture and heat. Do not allow liquid medicine to freeze.

What happens if I miss a dose?


Since cold medicine is taken when needed, you may not be on a dosing schedule. If you are taking the medication regularly, take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.


What happens if I overdose?


Seek emergency medical attention or call the Poison Help line at 1 800 222 1222. An overdose of acetaminophen can be fatal.

The first signs of an acetaminophen overdose include loss of appetite, nausea, vomiting, stomach pain, sweating, and confusion or weakness. Later symptoms may include pain in your upper stomach, dark urine, and yellowing of your skin or the whites of your eyes.


What should I avoid while taking this medication?


Ask a doctor or pharmacist before using any other cold, allergy, pain, or sleep medication. Acetaminophen (sometimes abbreviated as APAP) is contained in many combination medicines. Taking certain products together can cause you to get too much acetaminophen which can lead to a fatal overdose. Check the label to see if a medicine contains acetaminophen or APAP. Avoid drinking alcohol. It may increase your risk of liver damage while taking acetaminophen. This medicine may cause blurred vision or impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert and able to see clearly.
