Descriptions

Sacubitril
Sacubitril (given with valsartan) enhances natriuretic peptides to reduce heart-failure hospitalizations; watch for low blood pressure, hyperkalemia, and angioedema risk, avoid with recent ACE inhibitor.
Salbutamol
Rapid-acting inhaled bronchodilator used for acute wheeze; can cause tremor, tachycardia, headache; short-term relief only, monitor heart rate.
Salicylic acid
Topical acid that softens and removes warty or scaly skin; common local irritation and peeling; used in many OTC wart and acne products.
Salmeterol
Long-acting inhaled bronchodilator for control of asthma/COPD symptoms; not for acute attacks; may increase risk if used without inhaled steroids.
Salsalate
Oral anti-inflammatory related to salicylates used for pain and rheumatic conditions; can cause GI upset, bleeding risk, and should be used cautiously with other NSAIDs.
Saxagliptin
Oral diabetes medicine that increases incretin hormones to lower blood sugar; generally well tolerated but may increase risk of heart failure in some patients.
Scopolamine
Used as a transdermal patch for motion sickness and to reduce secretions; can cause dry mouth, drowsiness, blurred vision, confusion in older adults.
Secnidazole
Single-dose oral antibiotic for certain vaginal and protozoal infections; may cause GI upset and metallic taste; avoid alcohol with some nitroimidazoles.
Secukinumab
Biologic for moderate–severe plaque psoriasis and psoriatic arthritis; reduces inflammation but increases infection risk; require pre-treatment screening for TB.
Selegiline
Selective MAO-B inhibitor at low doses used for Parkinson’s and as a transdermal antidepressant; interactions with serotonergic drugs and tyramine precautions at higher doses.
Selinexor
Oral anticancer drug that blocks nuclear export proteins; can cause fatigue, nausea, low platelets and white cells; used in refractory cancers under specialist care.
Selpercatinib
Targeted therapy for cancers with RET alterations (lung, thyroid); can produce liver enzyme changes, hypertension; given under oncology supervision.
Selexipag
Oral drug to lower pulmonary vascular resistance in pulmonary arterial hypertension; common side effects include headache, jaw pain, nausea.
Sevoflurane
Volatile anesthetic with rapid onset and recovery used in operating rooms; may cause hypotension, respiratory depression, and rare malignant hyperthermia in susceptible individuals.
Semaglutide
Injectable (and oral form) GLP‑1 analog that lowers blood sugar and body weight; can cause nausea, may delay gastric emptying, monitor for pancreatitis.
Sertraline
Common antidepressant used for depression and anxiety disorders; side effects include nausea, sleep changes, sexual dysfunction, and rare serotonin syndrome with interacting drugs.
Sertaconazole
Topical antifungal cream used for ringworm and yeast skin infections; may cause local irritation or burning.

Oral agent increasing incretin levels to lower glucose; generally well tolerated, rare pancreatitis reports, low hypoglycemia risk unless combined with sulfonylureas/insulin.
Sodium nitroprusside
Rapid-acting IV vasodilator for very high blood pressure; very effective but risks cyanide toxicity with prolonged/high-dose use and causes reflex tachycardia.
