Descriptions
Enalapril
Relaxes blood vessels to lower blood pressure and improve heart function. Side effects can include a persistent dry cough, dizziness, and headache. It is important to monitor kidney function and potassium levels.

Works by increasing levels of serotonin, a mood-regulating chemical in the brain. Common side effects include nausea, insomnia, and sexual dysfunction. It may take several weeks to feel the full effects.
Esomeprazole
Reduces the amount of acid your stomach produces, providing relief from acid-related conditions. Long-term use should be discussed with a doctor due to potential risks like bone fractures and nutrient deficiencies.
Eszopiclone
Helps you fall asleep faster and stay asleep longer. It can cause an unpleasant metallic taste, next-day drowsiness, and dizziness. This medication is intended for short-term use.
Ezetimibe
Lowers cholesterol by preventing its absorption from the food you eat. It is often prescribed along with a statin medication. Side effects may include diarrhea, joint pain, and fatigue.

Etodolac
A nonsteroidal anti-inflammatory drug that reduces pain, swelling, and stiffness from arthritis or injury. Long-term use can increase the risk of stomach ulcers and heart problems.
Exenatide
An injectable medication that helps control blood sugar by increasing insulin production and slowing digestion. Nausea is a common side effect, especially when starting the medication.
Efavirenz
Part of a combination therapy for treating HIV. It prevents the virus from making copies of itself. It is often taken at bedtime to minimize central nervous system side effects like dizziness and vivid dreams.
Eletriptan
Treats migraine attacks after they have started by narrowing blood vessels in the brain. It does not prevent migraines. Side effects can include dizziness, drowsiness, and a feeling of chest tightness.
Emtricitabine
A cornerstone medication used with other drugs to treat or prevent HIV. It’s a key component in many single-tablet regimens. Generally well-tolerated, with side effects like headache or nausea.
Eplerenone
A type of diuretic (water pill) that helps lower blood pressure and reduce strain on the heart, especially after a heart attack. It can raise potassium levels, so blood tests are necessary.
Epoetin alfa
A man-made protein that signals the body to produce more red blood cells. It is used to treat anemia caused by chronic kidney disease or chemotherapy. Given as an injection under the skin or into a vein.
Erlotinib
A targeted therapy drug that blocks signals that cause cancer cells to grow and divide. It is a daily pill. A skin rash is a very common side effect, often indicating the drug is working.
Estradiol
An estrogen hormone used to relieve symptoms of menopause, such as hot flashes and vaginal dryness. It is available in many forms, including pills, skin patches, gels, and creams.
Ethambutol
An antibiotic that is always used in combination with other drugs to treat active tuberculosis. It can cause vision problems, so regular eye exams are crucial during treatment.
Ethosuximide
A medication used specifically to control absence (or “petit mal”) seizures, a form of epilepsy. Common side effects include nausea, stomach pain, drowsiness, and hiccups.
Etoposide
A chemotherapy drug that interferes with cancer cell growth and division. It is given by IV or as an oral capsule. It commonly causes hair loss, low blood counts, and nausea.
Everolimus
Used to treat certain types of cancer (like kidney and breast) or to prevent the body from rejecting a transplanted organ. It can cause mouth sores, rash, and an increased risk of infection.
Exemestane
An oral medication used to treat hormone-receptor-positive breast cancer in women after menopause. It works by significantly lowering estrogen levels. Common side effects include hot flashes and joint pain.
Evolocumab
A powerful, injectable medication for lowering LDL (“bad”) cholesterol. It is used when statins are not enough or not tolerated. Injections are typically given every two to four weeks.
Empagliflozin
A daily pill that lowers blood sugar by forcing the kidneys to remove excess sugar through urine. It has proven benefits for protecting the heart and kidneys. Can increase the risk of yeast and urinary tract infections.
Edoxaban
An oral anticoagulant (blood thinner) used to prevent stroke in people with atrial fibrillation or to treat deep vein thrombosis (DVT). The main risk is an increased chance of bleeding.
Elagolix
An oral medication that manages moderate to severe pain from endometriosis by lowering estrogen levels. Side effects can include hot flashes, headaches, and nausea. Long-term use may affect bone density.
Elexacaftor
A key part of a breakthrough combination therapy that helps the defective protein in cystic fibrosis work more effectively for people with certain genetic mutations. It has significantly improved quality of life.
Eltrombopag
A medication that stimulates the bone marrow to produce more platelets, helping to prevent bleeding. It is used for conditions like chronic ITP and aplastic anemia. Requires regular blood monitoring.
Enzalutamide
An oral medication for advanced prostate cancer that works by blocking testosterone from fueling cancer cell growth. Common side effects include extreme tiredness, hot flashes, and back pain.
Estrogens, conjugated
A mixture of estrogen hormones, typically derived from natural sources, used to treat hot flashes and other symptoms of menopause. It is available as a pill, cream, or injection.
Ethinyl estradiol
A synthetic form of estrogen that is a primary component in nearly all combination birth control pills, patches, and rings. It works with a progestin to prevent ovulation.
Eculizumab
A highly specialized intravenous drug used to treat rare and life-threatening blood and kidney disorders. It increases the risk of serious meningococcal infections, so vaccination is required before starting.
Edaravone
An intravenous medication that may help slow the decline in physical function for people with ALS. Its mechanism is thought to involve reducing oxidative stress in the nervous system.
Efinaconazole
A topical liquid applied directly to the affected toenail once daily for up to 48 weeks. It is one of the more effective topical treatments for fungal nail infections, but requires consistent use.
Eptifibatide
A potent antiplatelet drug given intravenously in a hospital to prevent blood clots during a heart attack or a cardiac procedure like stenting. Its main side effect is bleeding.
Esketamine
A prescription nasal spray used for adults with depression that has not responded to other treatments. It must be administered in a certified healthcare setting due to potential side effects like dissociation and sedation.

A once-daily medication used to control partial-onset seizures in adults and children. It is chemically related to carbamazepine and oxcarbazepine but may have fewer side effects for some people.
Evinacumab
An intravenous medication for a rare, severe genetic form of high cholesterol. It is used in addition to other cholesterol-lowering treatments to dramatically reduce LDL levels.
