    Herwicard information

    Herwicard is a medicinal product used for the treatment and prevention of angina pectoris (a medical condition which occurs as the patients' coronary arteries become constricted, no longer allowing sufficient oxygen to reach the heart muscle). It is currently considered that Nitroglycerin allows the blood vessel walls to relax and dilate, thus increasing the oxygen flow to the cardiac muscles.

    Herwicard indications

    Herwicard may be employed as a prophylactic means only against angina pectoris. Due to its slow action, this medicine is not suitable for use in the case of an acute attack. As such, your prescriber may recommend the usage of this medical product even if you are feeling well and do not have any symptoms. Also, your prescriber may advise you to use Herwicard for the treatment or prevention of other medical conditions that are not listed here. If you would like to obtain more information regarding the mechanism of action or possible uses of transdermal Nitroglycerine, it is best to ask your personal health care professional or a pharmacist.

    Herwicard warnings

    Herwicard should not be used for the treatment of patients that are allergic to Nitroglycerine or to any other ingredient of this medical product. Also, allergic reactions to the adhesives used for attaching the patches to the patient's skin have been reported - Herwicard should not be administered to patients that present a hypersensitivity to these adhesives.
    This medicine may cause or worsen already present hypotension, especially in elderly patients. As such, special consideration should be paid to such patients that are susceptible to developing low blood pressure. Herwicard should be safe to use during pregnancy and lactation; however it is best that you consult your personal health care provider to determine the risks and benefits of the therapy if you are or plan to become pregnant or if you are breast-feeding a baby.

    Herwicard intake guidelines

    Your prescriber will provide you with a set of Herwicard application guidelines, which you should closely follow in order to attain the best therapeutic effects. In some cases, the heath care professional's directions will not coincide with the following information; in such situations it is best that you follow the intake guidelines that your physician has provided.
    In order to ensure proper administration of the medicine, you will need to correctly apply the Herwicard patches to a clean, shaved area of skin - typically on the upper arm. Wash the area thoroughly with clean water and soap and rinse well before applying the patch. Remove any hair on the application site as it may hinder the medication delivery through the skin. Gently pat the skin dry with a soft towel (to prevent irritation caused by rubbing the skin) and apply the Herwicard patch, after removing the protective cover from the adhesive areas of the patch.
    If you have any questions or if you would like further details on how to properly apply the transdermal Nitroglycerine patches, it is best to consult with your personal physician.

    Herwicard dosage

    In most cases, the prescriber will direct a Herwicard starting dose of 0.2 to 0.4 mg per hour, increasing to maintenance doses of 0.4 to 0.8 mg per hour. The applications need to be kept on the skin for 12 to 14 hours daily allowing a 10 to 12 hour patch-off period. The duration of the therapy as well as the exact dosage will depend on a number of factors specific to each patient; it is best that you closely follow your prescriber's directions. Do not stop using the Herwicard patches without your physician's consent and do not employ a different dosage than you have been prescribed.



    Herwicard overdose

    Although an overdose with Nitroglycerine is a severe condition requiring immediate medical attention, it requires large doses of the substance. The Herwicard patches only contain a small concentration of Nitroglycerine and it is slowly released into the patient's organism; as such, an overdose with this medicine is highly unlikely as a result of your Herwicard therapy. However, if you have any reason to believe that you may be affected by an overdose you should immediately contact the nearest poisons center or the local hospital or clinic as you may need prompt medical assistance.

    Herwicard missed dose

    It is strongly suggested that you apply the Herwicard patches at around the same time every day, according to the schedule indicated by your prescriber. This will allow you to obtain the best therapeutic effects from the treatment and will reduce the chances of forgetting about any applications. However, if you forget to use one of the patches when appropriate, it is best to apply it as soon as you remember. If it is almost time for another application, you should completely skip the missed Herwicard dose and continue using the product as usual. Do not use larger doses of the medicine in order to compensate for a missed application.

    Herwicard side effects

    In rare cases, Herwicard may cause a number of adverse effects in patients following a treatment with this medical product. These may include flushing, dizziness, headaches, lightheadedness or a worsening of the angina. The side effects may be mild to severe, and should be brought to the attention of your health care specialist immediately when you begin experiencing them.
    Very rarely, you may experience swelling of the face, throat, lips or tongue, breathing troubles or skin affections such as rashes or hives - these are signs of an allergic reaction to the product and you should stop using the patches immediately if you notice any of these. Contact your physician as soon as possible.

    Herwicard drug reactions

    Herwicard may interact with other type of vasodilator medication and alcohol. You should inform your prescriber of any other drug you are currently taking prior to starting your Herwicard therapy.
