Headaches drive patients to the pharmacist's counter every day for help finding appropriate treatment.


Nonprescription analgesics for the management of headaches are widely utilized by many patients; however, the selection of these products may be overwhelming. It is estimated that 33% of OTC analgesics are used for the treatment and management of headaches.1 According to the American Headache Society, many patients choose these products because they are easy to obtain and use, and cost less than prescription medications.2 The Handbook of Nonprescription Drugs states that the types of headaches most often amendable to self-treatment with nonprescription analgesics include tension-type headaches, migraines, and sinus headaches.1

Pharmacists are in a pivotal position to assist patients in the selection and proper use of these products and to screen for possible contraindications, drug–drug interactions, and potential therapeutic duplications. By reviewing a patient’s medication profile, pharmacists can identify pharmacologic agents that may trigger headaches, provide clinical recommendations, and encourage patients to discuss the issue with their primary health care provider.

Headache Triggers

Headaches may be caused by a number of factors, which can include stress, anxiety, environmental factors such as noise, poor lighting conditions when reading or using a computer, significant changes in sleeping and eating patterns (eg, skipping meals or not getting enough sleep), use of certain pharmacologic agents, fluctuations of hormone levels, and food sensitivities. 1,3

Types of Headaches

In general, headaches are categorized as  OTC focus  A Pharmacist’s Guide to OTC Therapy Yvette C. Terrie, BSPharm, RPh Pharmacists Play a Critical Role in Helping Patients Select the Right Product to Manage Headaches Safely and Appropriately primary or secondary.1,4 Primary headaches account for an estimated 90% of headaches and are not linked to an underlying illness.4 According to the American Headache Society, examples of primary headaches include tension headache, cluster headache, migraine, and medication overuse headaches (also known as rebound headaches).1,4-6

A headache is classified as secondary when it is the result of an underlying medical condition.1,4-6 Some of the conditions that may cause secondary headaches include sinusitis, severe hypertension, head trauma, hematomas, temporomandibular joint dysfunction, metabolic disorders, cerebral hemorrhage, and meningitis. 1,7-9 Patients experiencing secondary headaches should always be referred to their primary health care provider for further medical evaluation and treatment.

Tension Headaches

Tension headaches—commonly referred to as stress headaches—are considered the most prevalent type of headache, affecting an estimated 75% of individuals in the United States.4 They occur most commonly in women.1,4 Tension headaches may be classified as episodic or chronic,1 and are characterized by mild pain that gradually initiates at the back of the head and upper neck. The pain is usually bilateral and is often described as tight, pressing, and constricting.1,4-6 The duration of tension headaches ranges from minutes to days.1-3 Stress, anxiety, fatigue, eyestrain from reading and computer use, and muscular tension are common causes of tension headaches.1,6 Patients who experience frequent and/ or chronic tension headaches should be referred to a physician for further evaluation. 5

Migraine Headaches

Migraines affect approximately 12% of the US population and occur most often in individuals aged 15 to 55 years.9 Most individuals experience their first migraine before age 30.1,8,9 Migraines occur in an estimated 18% of women and 6% of men.1,7 In addition, an estimated 4% to 10% of the pediatric population experience migraines.8,10 About 70% to 80% of migraine sufferers have a family member with a history of migraines.1,8,9

Migraine headaches are characterized by pain that is typically unilateral and is often described as intense and throbbing. 1-3 The pain associated with migraine headaches may be preceded by aura and onset may be abrupt; however, some patients do not experience aura. Patients may report sensitivity to light, noise, or odors and may experience nausea and vomiting.1-4 The duration of migraines usually ranges from a few hours to about 72 hours.4 Many women experience migraine attacks during the premenstrual cycle. Migraines, however, may also occur during and after the menstrual cycle.1 Women may also experience migraines during perimenopause and menopause.

OTC Headache Treatment

Nonprescription analgesics available for the treatment and management of headaches include acetaminophen, nonsteroidal anti-inflammatory drugs including ibuprofen and naproxen, and salicylates (aspirin, magnesium salicylate, and sodium salicylate). 1 These products are available in a variety of formulations as single entity or combination products, such as tablets, capsules, gel capsules, liquigels, enteric coated, extended or sustained release forms, liquids, suspensions, effervescent tablets, rapid release gel capsules, powders, and chewable tablets. Combination products include decongestants, antihistamines, and analgesics for treating sinus headaches. Patients should be advised to read labels carefully, especially when using multi-ingredient products, to avoid unnecessary drug use or therapeutic duplications.

In addition, several alternative medications are available for the relief and management of headache symptoms, including Hylands Headache Tablets, and topical products such as WellPatch Migraine Cooling Therapy Pads. New products on the market include Sinol All-Natural Nasal Spray with MucoAd for Fast Headache Relief, and Headache Buster Nasal Spray, which includes 3 active ingredients: capsaicin, feverfew, and peppermint oil.11,12

The Role of the Pharmacist

Prior to recommending any nonprescription analgesics, pharmacists should always screen for potential allergies, contraindications, and drug–drug interactions. Identifying possible triggers and avoiding and modifying them can help decrease the frequency of headaches in patients who experience frequent tension or migraine headaches.1 Nonpharmacologic measures that may be beneficial in alleviating or preventing headaches include relaxation techniques, avoiding stress, eating a balanced diet, and getting an adequate amount of sleep.

During counseling, patients should be reminded about the proper use of analgesics, including recommended duration, and should be advised to take these products with food or milk if they experience an upset stomach. Patients should also be counseled on the potential adverse effects associated with the use of these products.

Although the majority of headaches can be easily managed and only last a few hours, patients should be encouraged to seek further medical care if they do not obtain any relief after using these products, if they experience chronic headaches, or if headaches increase in intensity or frequency. Patients should also be reminded that excessive use of these products could lead to rebound headaches or medication overuse headaches.1
