A decongestant, or nasal decongestant, is a type of pharmaceutical drug that is used to relieve nasal congestion in the upper respiratory tract. The active ingredient in most decongestants is either pseudoephedrine or phenylephrine (the latter of which has disputed effectiveness). Intranasal corticosteroids can also be used as decongestants and antihistamines can be used to alleviate runny nose, nasal itch, and sneezing. Topical decongestants on topical application as dilute solution (0.05–0.1%) produce local vasoconstriction. Regular use of decongestants for long periods should be avoided because mucosal ciliary function is impaired: atrophic rhinitis and anosmia (loss of the sense of smell) can occur due to persistent vasoconstriction. Decongestants can be absorbed from the nose via an inhaler and produce systemic effects, mainly central nervous system stimulation and rise in blood pressure. These drugs should be used cautiously in hypertensives and in those receiving monoamine oxidase inhibitors (MAOIs), as they can cause hypertensive crisis. Migraines are severe, debilitating headaches that are usually characterized by an intense throbbing or pulsing in one area of your head. They can include sensitivity to light, sound, and smell, create visual disturbances such as auras, and can even cause nausea or vomiting. Migraines are more than a headache and can affect your everyday life. There are two categories of drugs used to treat migraines: These drugs are taken at the onset of migraine symptoms or auras to relieve a headache or reduce its severity. Taking any of these drugs too often can lead to a rebound headache, headaches that arise from the overuse of medication, which then necessitates additional medication. If you need to use acute migraine drugs more than 9 times per month, talk to your doctor about possible preventive treatments. Some over-the-counter (OTC) painkillers are commonly used for migraines, but many are only available in prescription strength. Aside from acetaminophen, an analgesic that only relieves pain, these drugs are nonsteroidal anti-inflammatory drugs (NSAIDs), which relieve pain and reduce inflammation: Many OTC drugs marketed specifically for migraine or headaches in general combine one or more of the drugs above with a small amount of caffeine, which can make them work more quickly and effectively, especially for mild migraine headaches.
