What is Imdur and why is it prescribed? Imdur is prescribed to prevent angina pectoris. Imdur does not relieve angina attacks already underway. Imdur may cause severe low blood pressure, especially when you are standing or if you sit up quickly. People taking blood pressure medication or those who have low blood pressure should use Imdur with caution. How should you take Imdur? Follow your doctors directions for taking Imdur. To maintain this drug's protective effect, it is important that you take it exactly as prescribed. Take Imdur once a day, when you get up in the morning. It may be taken with or without food. Imdur tablets should not be crushed or chewed. Swallow them with half a glass of liquid. Do not switch to another brand of isosorbide mononitrate without consulting your doctor or pharmacist. If you miss a dose take it as soon as you remember. If it is almost time for your next dose, skip the one you missed and go back to your regular schedule. Do not take two doses at the same time. Store Imdur at room temperature. Are there any Imdur side effects? Imdur side effects cannot be anticipated. If any develop or change in intensity, inform your doctor as soon as possible. Headache is the most common side effect; usually, aspirin or acetaminophen will relieve the pain. The headaches associated with Imdur usually subside within a short time after treatment with the drug begins. Check with your doctor if your headaches persist or become more intense. Another common Imdur side effect is dizziness. Less common or rare Imdur side effects may include abdominal pain, abnormal hair texture, abnormal heart sounds, abnormal or terrifying dreams, abnormal vision, acne, anemia, anxiety, back pain, bacterial infection, black stools, breast pain, bronchitis, chest pain, confusion, constipation, coughing, decreased sex drive, depression, diarrhea, difficult or labored breathing, difficulty concentrating, diminished sense of touch, drooping eyelid, dry mouth, earache, excessive amount of urine, fatigue, fever, fluid retention and swelling, flu-like symptoms, flushing, frozen shoulder, gas, general feeling of illness, heart attack, heart failure, heart murmur, hemorrhoids, high blood pressure, hot flashes, impotence, inability to sleep, increased mucus from the lungs, increased sweating, indigestion, inflamed eyes, inflammation of the stomach, inflammation of the tongue, inflammation of the vagina, intolerance of light, irregular heartbeat, itching, joint pain, kidney stones, leg ulcer, loose stools, low blood pressure, migraine, muscle and/or bone pain, muscle weakness, nasal or sinus inflammation, nausea, nervousness, palpitations, paralysis, perforated eardrum, pneumonia, purple or red spots on the skin, rapid heartbeat, rash, ringing in the ears, severe pain in calf muscles during walking, sleepiness, slow heartbeat, sore throat, stomach ulcer with or without bleeding, stuffy nose, tingling or pins and needles, tremor, twisted neck, urinary tract infection, varicose veins, vertigo, viral infection, vomiting, weakness, wheezing, worsening of angina pectoris, and yeast infection. What are the possible food and drug interactions when taking Imdur? If Imdur is taken with certain other drugs, the effects of either could be increased, decreased, or altered. Be sure to inform your doctor of all the prescription and over the counter medications you are taking. Extreme low blood pressure with dizziness and fainting upon standing up may occur if Imdur is taken with the impotence drug Viagra or calcium-blocking blood pressure medications such as Calan, Cardizem, and Procardia. Alcohol may interact with Imdur and cause a swift decrease in blood pressure, possibly resulting in light-headedness. Are there any special warnings about Imdur? Do not abruptly stop taking Imdur. Follow your doctor's plan for a gradual withdrawal. Since Imdur can cause dizziness, you should be careful while driving, operating machinery, or performing other tasks that demand concentration. Nitrate-type medications such as Imdur may aggravate angina caused by certain heart conditions. Do not try to avoid a headache by changing your dose. If your headache stops, it may mean the drug has lost its effectiveness. Be sure to tell your doctor about any medical conditions you have before starting Imdur therapy. |
