As Scotland braces for a mini-heatwave with temperatures expected to reach 31°C in parts of the country, a dermatologist has issued a warning that everyday medications could be making people more vulnerable to UV-related skin damage. Skin cancer is now the most common and fastest-rising cancer in the UK, with over 17,500 new melanoma cases and around 250,000 non-melanoma skin cancer cases confirmed annually.
Medication-Induced Photosensitivity: An Overlooked Risk
According to Dr Conal Perrett, consultant dermatologist at The Devonshire Clinic, dozens of commonly prescribed medications can increase the skin's sensitivity to ultraviolet radiation. This condition, known as photosensitivity, causes the skin to burn more easily and heightens susceptibility to UV-related damage.
Dr Perrett explains: "It's important people understand that skin cancer prevention isn't only about avoiding sunburn on holiday. UV exposure builds up gradually over time through daily habits and routines people often don't think about. We're also seeing increased awareness around photosensitive medications. Certain antibiotics, acne treatments, anti-inflammatory drugs, antidepressants and even some herbal supplements can make the skin significantly more vulnerable to UV damage."
15 Common Medications Linked to Increased UV Sensitivity
The following medications are associated with heightened UV sensitivity and their common uses:
- Ibuprofen – Pain relief and inflammation
- Naproxen – Arthritis and chronic pain
- Doxycycline – Acne, chest infections and STIs
- Lymecycline – Acne treatment
- Ciprofloxacin – Urinary tract and bacterial infections
- Amitriptyline – Chronic pain, migraines and depression
- Sertraline – Depression and anxiety
- Citalopram – Depression and anxiety
- Hydrochlorothiazide – High blood pressure
- Furosemide – High blood pressure and fluid retention
- Isotretinoin – Severe acne treatment
- Azathioprine – Autoimmune conditions and organ transplant patients
- Amiodarone – Heart rhythm disorders
- Diclofenac – Pain and inflammation
- St John's Wort – Herbal supplement for low mood
Precautions and Advice for Sun Exposure
Dermatologists advise that patients should never stop taking prescribed medication without consulting a healthcare professional. However, those taking photosensitive medications should take additional precautions when spending time in the sun.
Dr Perrett adds that early action can make a significant difference. While most skin changes are harmless, skin cancer is far more treatable when detected early. He recommends the following steps:
- Check your skin regularly – Watch for new moles, sores that do not heal, or changes in existing moles, including asymmetry, irregular borders, colour changes, growth in size, or evolving appearance.
- Book a GP appointment promptly – Seek medical advice if you notice anything unusual or suspicious.
- Take photos of changes – Tracking changes over time can help doctors assess suspicious areas.
- Avoid self-treatment – Do not pick at or attempt to remove suspicious lesions yourself.
- Protect your skin – Use SPF 30+, avoid sunbeds, and limit unnecessary UV exposure, including from nail lamps and prolonged time near windows.
- Seek urgent advice if symptoms worsen – Bleeding, pain, rapid growth, or sudden colour changes should be assessed quickly.
