I am a firm believer in the Sudafed Brand. They make just about the best cold, allergy, sinus and congestion medicine there is to be had. They are always effective and long lasting and the price is reasonable. I take these for a variety of ailments. I suffer from asthma and these are great for an "all day" pill when I don't want to be bothered with multipile doses and they are a strong sinus medication. Congestion Relief They work wonderfully for a variety of ailments, they work well with my asthma, and also great with allergy relief and for cold symptoms they are outstanding for comfort. Chest Congestion Relief You will be able to tell a big difference in your chest congestion almost immediately and they last for a long time. Sometimes I break them in half because they do last so long, and sometimes they keep me awake. Relief of Aches & Pains They don't work so well for aches and pains if that is your problem you will have to take some aspirin or tylenol along with the Sudafed. They do nothing for your pain. Cough Suppression Will stop your cough for about 12 hours and clear up your congestion also.
