The factors why these nerves are activated are not clearly understood. Most headaches go away on their own or are quickly treated with more than the counter (OTC) drugs.
Headache varieties
There are two most important categories of headache: main and secondary.
The significant types of primary headaches contain:
- Tension headache
- Cluster headache
- Migraine
Main headaches are not triggered by other underlying medical circumstances. Even more than 90% of headaches are primary.
Secondary
Secondary headaches result from other medical circumstances, such as cerebrovascular illness, head trauma, infection, tumor, and metabolic disorder. These account for fewer than 10% of all headaches. Head discomfort also can result from syndromes involving the eyes, ears, neck, teeth, or sinuses. In these situations, the underlying condition need to be diagnosed and treated.

The occasional tension headache can be alleviated by a hot shower, massage, sleep, and by means of patient recognition and avoidance of tension aspects.
For episodic tension headaches that occur less than three times per week, OTC pain relievers such as aspirin, acetaminophen (Tylenol) or ibuprofen (Advil, Motrin) are handy and reliable. Combination items of pain medication with caffeine may perhaps assist some consumers, but also may possibly be habit forming. Use of any OTC discomfort reliever ought to be restricted to no much more than two or three days per week. If pain medicines are overused, rebound headaches might possibly occur on the days that medications are not taken.
Chronic tension headaches are much more tough to treat, given that rebound headaches are prevalent when discomfort relievers are stopped. The most effective medicines for therapy of chronic tension headaches are tricyclic antidepressants (amitriptyline HCl, doxepin HCl, nortriptyline HCl). On the other hand, it is sometimes extra powerful to avoid these headaches than to treat them.
Some individuals are able to treat their tension headaches with out medications. An ice compress, a heating pad or a massage to any tight places in the neck and shoulders can be very helpful.

Lithium (Carbolith, Duralith, Lithane, Lithobid, Lithonate and other people) and verapamil (Isoptin, Calan, Chronovera, Verelan, Novo-Veramil) are the two drugs that are most helpful at accomplishing this. Other drugs utilised for this objective comprise of prednisone (Deltasone, Meticorten, Orasone 1, Winpred and others), cyproheptadine (Periactin) and methysergide (Sansert). Prophylactic medications frequently are begun early throughout a cycle of cluster headaches and continued for two weeks longer than the usual cycle.
Abortive remedies incorporate inhalation of 100% oxygen. Inhaling 100% oxygen for about 15 minutes by means of a facemask has proven to be useful when it is performed at the initial signs of an attack.

- abortive medications - drugs that are taken when a headache begins
- preventive medications - drugs that are taken every day to stop migraines
Abortive Medicines
Migraine-precise abortive medicines commonly are necessary for moderate to severe migraine headaches. When feasible, an abortive medication should certainly be taken instantly following an aura or migraine headache begins. Nevertheless overusing abortive medications can lead to chronic headaches, that occur day just after day with no a certain cause or diagnosis. Quite a few prescription and nonprescription drugs are utilised as abortive medications: aspirin, ibuprofen (Advil, Apsifen, Motrin, Nuprin and other brand names) or naproxen (Aleve, Anaprox, Naprosyn)
Efficient agents on the market by prescription contain:
- Triptans - sumatriptan (Imitrex), naratriptan (Amerge), zolmitriptan (Zomig) and rizatriptan (Maxalt). Triptan drugs are valuable in 60% to 65% of patients, completely or drastically relieving migraine pain and linked symptoms within two hours of administration. Triptans cut down inflammation and constrict the blood vessels. The triptan with the longest history of use is sumatriptan (Imitrex).
- Ergots - sublingual ergotamine (Ergomar) and dihydroergotamine (Migranal). Ergots trigger constriction of blood vessels, but ergots tend to cause even more constriction of vessels in the heart and other parts of the body than the triptans, and their effects on the heart are extra prolonged than the triptans. Ergots are not as safe as the triptans.
- Midrin. It is a combination of isometheptene (a blood vessel constrictor), acetaminophen (a discomfort reliever), and dichloralphenazone (a mild sedative)
Preventive Medicines
Preventive medication are prescribed when migraine attacks that do not respond nicely to abortive medicines or adverse reactions to abortive medications occur, migraine attacks occur too regularly, difficult migraines. Several drugs are listed as potentially useful to avoid recurrent migraine attacks. The drugs in the following classes are useful to avoid recurrent migraine attacks:
- Beta-blockers. Propranolol (Inderal) and nadolol (Corgard) have a beneficial track record of getting safe and valuable. Metoprolol (Lopressor) and atenolol (Tenormin) are reasonable alternatives. Beta-blockers have been utilised for many years to stop migraine headaches. It is not known how beta-blockers avoid migraine headaches.
- Tricyclic antidepressants. These medications are very helpful, but quite often have troublesome side effects such as sedation, blurred vision, dry mouth and constipation. The 1st choice is generally amitriptyline (Elavil). Nortriptyline (Pamelor, Aventyl), doxepin (Sinequan), imipramine (Tofranil) also can be tried.
- Anticonvulsants. Of the drugs in this class, valproate (Depakote, Epival) has the very best evidence to support making use of it for prevention. Gabapentin (Neurontin) and topiramate (Topamax) also are successful. It is not known how anticonvulsants perform to stop migraine headaches.
- Serotonin antagonists. Methysergide (Sansert) has been accessible for a number of years and is especially valuable. Methysergide prevents migraine headaches by constricting blood vessels and lowering inflammation of the blood vessels. Nonetheless, this medication has side effects that are potentially extremely severe and for that reason is not widely employed.
