Conditions We Cover

Pain Pain is the body's signal that something needs attention, ranging from a brief, sharp sensation after an injury to a persistent ache lasting weeks or months. Mild to moderate pain is often managed with NSAIDs such as etodolac. 1 medicine View → Pain Panic Disorder Panic disorder causes repeated, unexpected panic attacks along with weeks of dreading the next one. Antidepressants, especially SSRIs, are the mainstay of long-term treatment, usually paired with talking therapy. 3 medicines View → Panic Disorder Parasitic Worm Infection Parasitic worm infections happen when helminths such as roundworms, hookworms, and tapeworms take hold in the gut. A short course of an antiparasitic medicine, most often albendazole, clears most cases. 1 medicine View → Parasitic Worm Infection Parkinson's Disease Parkinson's disease is a progressive condition in which the brain gradually loses the cells that produce dopamine, making movement harder to initiate and control. Levodopa remains the most effective treatment. 9 medicines View → Parkinson's Disease Parkinson's Disease Dementia Parkinson's disease dementia is a decline in memory, attention, and daily function that develops in people already living with Parkinson's disease. Rivastigmine is the treatment with the strongest evidence base. 1 medicine View → Parkinson's Disease Dementia Parkinsonism Parkinsonism is a group of conditions that cause tremor, stiffness, and slowed movement by disrupting the brain's motor control circuits. Parkinson's disease is the most common cause, but medicines and other factors can trigger it too. 1 medicine View → Parkinsonism Paroxysmal Supraventricular Tachycardia Paroxysmal supraventricular tachycardia (PSVT) is a sudden-onset rapid heart rhythm originating above the ventricles, typically racing at 150 to 250 beats per minute. Vagal manoeuvres and antiarrhythmic medicines like flecainide manage it. 1 medicine View → Paroxysmal Supraventricular Tachycardia Peptic Ulcer Disease Peptic ulcer disease causes open sores in the stomach or small intestine lining, producing burning abdominal pain, bloating, and nausea. Acid-suppressing medicines let the lining heal. 2 medicines View → Peptic Ulcer Disease Peptic Ulcer Prophylaxis Peptic ulcer prophylaxis means protecting the stomach lining before an ulcer forms, especially in people taking medicines that raise the risk of damage. Misoprostol is one option used to shore up the stomach's defences. 1 medicine View → Peptic Ulcer Prophylaxis Peripheral Arterial Disease Peripheral arterial disease narrows the arteries that supply the legs and feet, causing cramping pain on walking. It is managed with antiplatelet medicines such as clopidogrel alongside lifestyle changes. 1 medicine View → Peripheral Arterial Disease Persistent Aggression in Dementia Persistent aggression in dementia is repeated hitting, shouting, or threatening behaviour that goes beyond ordinary agitation. It is managed first with non-drug strategies, then with low-dose antipsychotics such as risperidone when needed. 1 medicine View → Persistent Aggression in Dementia Pharyngitis Pharyngitis is inflammation of the throat that causes soreness and pain on swallowing. Most cases are viral, but bacterial pharyngitis is treated with antibiotics. 3 medicines View → Pharyngitis Phobic States A phobic state is a lasting, disproportionate fear of a specific object or situation that triggers avoidance. Treatment centres on exposure-based therapy, with medicines like clomipramine used for severe or resistant cases. 1 medicine View → Phobic States Photoageing Photoageing is skin damage from years of UV exposure, causing wrinkles, uneven pigmentation, and loss of firmness. Topical retinoids like tretinoin are the best-evidenced treatment. 2 medicines View → Photoageing Pityriasis Versicolor Pityriasis versicolor is a common fungal skin infection that causes patchy discolouration, driven by an overgrowth of yeast that normally lives on the skin. It's treated with antifungal medicines. 1 medicine View → Pityriasis Versicolor Plaque Psoriasis Plaque psoriasis is a chronic autoimmune condition causing raised, scaly red patches, most often on the elbows, knees, scalp, and lower back. It's managed with topical treatments such as calcipotriol and betamethasone. 3 medicines View → Plaque Psoriasis Pneumonia Pneumonia is a lung infection that inflames the air sacs, causing cough, fever, and breathlessness. Bacterial pneumonia is treated with antibiotics. 2 medicines View → Pneumonia Polycythaemia Vera Polycythaemia vera is a rare blood cancer that causes the bone marrow to overproduce red blood cells, raising the risk of clots, stroke, and heart attack. It is managed with regular venesection and, when needed, cytoreductive medicines like hydroxycarbamide. 1 medicine View → Polycythaemia Vera Post-Myocardial Infarction Post-myocardial infarction care protects the heart in the weeks and months after a heart attack, combining medicines like ACE inhibitors with lifestyle changes to lower the risk of a second event. 2 medicines View → Post-Myocardial Infarction Post-Operative Nausea and Vomiting Post-operative nausea and vomiting (PONV) is a common complication of surgery and anaesthesia, prevented and treated with antiemetic medicines such as ondansetron. 1 medicine View → Post-Operative Nausea and Vomiting Post-Operative Otitis Post-operative otitis is inflammation of the ear canal or middle ear following ear or nearby surgery, treated with a topical antibiotic and an anti-inflammatory drop. 1 medicine View → Post-Operative Otitis Post-Traumatic Stress Disorder Post-traumatic stress disorder (PTSD) is a mental health condition that develops after a traumatic event, causing intrusive memories, avoidance, and heightened alertness. It's treated with trauma-focused therapy and, when needed, SSRIs such as sertraline. 1 medicine View → Post-Traumatic Stress Disorder Postural Hypotension Postural hypotension (orthostatic hypotension) is a drop in blood pressure on standing that causes dizziness or fainting. It's managed with lifestyle changes and, when needed, medicines such as midodrine. 1 medicine View → Postural Hypotension Pre-Exposure Prophylaxis Pre-exposure prophylaxis (PrEP) is a daily antiretroviral regimen that HIV-negative people at substantial risk take to prevent HIV infection, cutting the risk of sexual transmission by around 99% when taken consistently. 1 medicine View → Pre-Exposure Prophylaxis Premature Ejaculation Premature ejaculation is the most common male sexual concern worldwide, and it responds well to a range of effective treatments, from oral medicines like dapoxetine to topical numbing agents. 24 medicines View → Premature Ejaculation Primary Biliary Cholangitis Primary biliary cholangitis is a chronic autoimmune liver disease that slowly damages the bile ducts, causing bile to build up and injure the liver. It has no cure but responds well to ursodeoxycholic acid, which protects liver function for years. 1 medicine View → Primary Biliary Cholangitis Primary Hypercholesterolaemia Primary hypercholesterolaemia is an inherited condition that keeps LDL cholesterol persistently high regardless of diet, raising the risk of early heart disease. It's treated with statins, often combined with newer agents like bempedoic acid. 1 medicine View → Primary Hypercholesterolaemia Prolactinoma A prolactinoma is a benign pituitary tumour that produces too much prolactin, disrupting reproductive hormones in both men and women. It is usually treated with cabergoline, a medicine that suppresses prolactin and shrinks the tumour. 1 medicine View → Prolactinoma Prostate Cancer Prostate cancer is one of the most common cancers in men, usually growing slowly and caught early through PSA blood tests. Advanced disease is managed by lowering androgen activity with medicines such as flutamide and abiraterone. 2 medicines View → Prostate Cancer Prostatitis Prostatitis is inflammation of the prostate gland, ranging from a sudden bacterial infection to persistent pelvic discomfort with no clear cause. Bacterial prostatitis is treated with antibiotics such as levofloxacin. 1 medicine View → Prostatitis Protozoal Infection Protozoal infections are caused by single-celled parasites that spread through contaminated food, water, or insect bites and can affect the gut, blood, liver, or skin. Intestinal infections are usually treated with metronidazole. 1 medicine View → Protozoal Infection Pruritus Pruritus is persistent or widespread itching that can stem from skin conditions, allergies, liver or kidney disease, or nerve problems. Treatment targets the underlying cause, using antihistamines or bile-acid binders depending on the trigger. 2 medicines View → Pruritus Psoriasis Psoriasis is a long-term skin condition in which the immune system speeds up skin cell turnover, causing thick, scaly plaques. Treatment ranges from topical steroid creams to systemic medicines like methotrexate for more severe cases. 11 medicines View → Psoriasis Psoriatic Arthritis Psoriatic arthritis is an autoimmune joint condition that develops in some people with psoriasis, causing swollen, painful joints alongside skin symptoms. 1 medicine View → Psoriatic Arthritis Psychotic Disorders Psychotic disorders disrupt a person's grip on reality with hallucinations, delusions and disorganised thinking. Antipsychotic medicines are the cornerstone of long-term treatment. 1 medicine View → Psychotic Disorders Pulmonary Arterial Hypertension Pulmonary arterial hypertension is raised blood pressure in the lung arteries, treated with targeted medicines that widen the vessels and reduce strain on the heart. 3 medicines View → Pulmonary Arterial Hypertension Pulmonary Embolism Pulmonary embolism is a blood clot in the lungs and a medical emergency, treated urgently with anticoagulants to stop the clot growing and prevent new ones. 1 medicine View → Pulmonary Embolism
