Causes and symptoms
- "Worst headache of my life." This may indicate subarachnoid hemorrhage from a ruptured aneurysm (swollen blood vessel) in the head or other neurological emergency.
- Headache accompanied by one-sided weakness, numbness, visual loss, speech difficulty, or other signs. This may indicate a stroke. Migraines may include neurological symptoms.
- Headache that becomes worse over a period of 6 months, especially if most prominent in the morning or if accompanied by neurological symptoms. This may indicate a brain tumor.
- Sudden onset of headache. If accompanied by fever and stiff neck, this can indicate meningitis.
- acupuncture or acupressure
- herbal remedies using feverfew (Chrysanthemum parthenium), valerian (Valeriana officinalis), white willow (Salix alba), or skullcap (Scutellaria lateriflora), among others
- homeopathic remedies chosen specifically for the individual and his/her type of headache
- magnesium supplements
- regular physical exercise
- relaxation techniques, such as meditation and yoga
- transcutaneous electrical nerve stimulation (TENS) (A procedure that electrically stimulates nerves and blocks the signals of pain transmission.)
Immediate attention by a health care provider is indicated when (1) a severe headache comes on suddenly without apparent cause; (2) there are accompanying symptoms of neurological abnormality, for example, blurring of vision, mental confusion, loss of mental acuity or consciousness, motor dysfunction, or sensory loss; or (3) the headache is highly localized, as behind the eye or near the ear, or in one location in the head. Fever and stiffness of the neck accompanying the headache may indicate meningitis.
cyclosporine ophthalmic emulsion
Restasis, Sandimmun (UK)CNS: tremor, headache, confusion, paresthesia, insomnia, anxiety, depression, lethargy, weakness
Pharmacologic class: Polypeptide antibiotic

FDA Box Warning
• Drug should be prescribed only by physicians experienced in managing systemic immunosuppressive therapy for indicated disease. At doses used for solid-organ transplantation, it should be prescribed only by physicians experienced in immunosuppressive therapy and management of organ transplant recipients. Patient should be managed in facility with adequate laboratory and medical resources. Physician responsible for maintenance therapy should have complete information needed for patient follow-up.
• Neoral may increase susceptibility to infection and neoplasia. In kidney, liver, and heart transplant patients, drug may be given with other immunosuppressants.
• Sandimmune should be given with adrenal corticosteroids but not other immunosuppressants. In transplant patients, increased susceptibility to infection and development of lymphoma and other neoplasms may result from increased immunosuppression.
• Sandimmune and Neoral aren't bioequivalent. Don't use interchangeably without physician supervision.
• In patients receiving Sandimmune soft-gelatin capsules and oral solution, monitor at repeated intervals (due to erratic absorption).

• In postoperative patients, switch to P.O. dosage as tolerance allows.
• Be aware that Sandimmune and Neoral aren't bioequivalent. Don't use interchangeably.
• Before administering eyedrops, invert unit-dose vial a few times to obtain a uniform, white, opaque emulsion.
• Know that eyedrops can be used concomitantly with artificial tears, allowing a 15-minute interval between products.

• Observe patient for first 30 to 60 minutes of infusion. Monitor frequently thereafter.
• Monitor cyclosporine blood level, electrolyte levels, and liver and kidney function test results.
• Assess for signs and symptoms of hyperkalemia in patients receiving concurrent potassium-sparing diuretic.
• Advise patient to dilute Neoral oral solution with orange or apple juice (preferably at room temperature) to improve its flavor.
• Instruct patient to use glass container when taking oral solution. Tell him not to let solution stand before drinking, to stir solution well and then drink all at once, and to rinse glass with same liquid and then drink again to ensure that he takes entire dose.
• Tell patient taking Neoral to avoid high-fat meals, grapefruit, and grapefruit juice.
• Advise patient to dilute Sandimmune oral solution with milk, chocolate milk, or orange juice to improve its flavor.

Patient discussion about headache
Q. Are there different Kinds of Headaches? I noticed that my headaches don't always feel the same way. Are there different kinds of headaches?
1. Tension headaches: caused by stress, fatigue, poor posture, eye strain, tobacco and alcohol use or before and after a period (for women).
2. Migraine headache: Migraine is the cause of 20 per cent of all headaches. This type of headache occurs when blood vessels of the head and neck constrict, resulting in a decrease in blood flow to the vessels.
Q. What are some ways to treat headaches? I have been suffering from headaches for a long time now. How can I treat them?
• Avoid excessive use of alcohol and tobacco.
• Engage in correct posture while sitting and working. The type of chair you use is important. It should be one that maximizes comfort and good posture and may need to be adjusted to suit your needs.
• Perform relaxation techniques on a consistent basis.
• Get plenty of fresh air and exercise.
• Some people find that taking the natural herbal treatment Feverfew is very effective at reducing or preventing their headaches occurring. This needs to be taken daily – even if no headache is present – to have an effect. Consult your GP before starting this.
