Warnings and precautions

Take it with or just after food, and for the shortest time that works. Stop and seek urgent care for black or tarry stools, vomiting blood, or severe stomach pain — this group can cause bleeding from the stomach. Long or high-dose use raises the risk of heart attack, stroke and kidney injury, particularly in older people and those already at risk. Avoid if you are dehydrated or have an illness with vomiting or loose motions — the kidneys are vulnerable then. Must be avoided in the last three months of pregnancy. Medicines that suppress the immune system need regular blood tests — do not miss them. Report fever, sore throat, mouth ulcers or unusual bruising promptly if you are on an immune-suppressing medicine. Tell your doctor about any infection, and before any vaccination. Methotrexate for arthritis is taken ONCE A WEEK. Taking it daily by mistake is dangerous — check the day on your pack. This is for short-term relief. See a doctor if you need it most days for more than a couple of weeks. Seek urgent care for chest pain that spreads to the arm or jaw, comes with sweating or breathlessness — do not assume it is acidity. Antacids interfere with the absorption of many other medicines. Take them at least two hours apart from anything else.

Do not take Fenlong-S if

Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Not for people with an active stomach ulcer, severe kidney or heart failure, or asthma triggered by aspirin or anti-inflammatory painkillers. Not in the third trimester of pregnancy. Not for people with an active serious infection, or with severe liver or bone-marrow disease. Several of these medicines must not be used in pregnancy. Magnesium-containing antacids are avoided in significant kidney disease.

Interactions with other medicines

Combining with a blood thinner or aspirin sharply raises the bleeding risk. Reduces the effect of blood pressure medicines and water tablets, and together with them can harm the kidneys. Never take two anti-inflammatory painkillers at the same time. Tell your doctor about all other medicines, especially anti-inflammatory painkillers and antibiotics. Live vaccines are generally avoided while on immune-suppressing treatment. Reduces the absorption of thyroid tablets, iron, and several antibiotics — separate them by at least two hours.

How to store Fenlong-S Tablet

Store below 30°C in the original pack, away from direct sunlight and moisture. Keep out of the reach of children.

Expert advice for Fenlong-S Tablet

Use the lowest dose for the shortest period. If you need a painkiller regularly, see your doctor rather than continuing on your own. Paracetamol is the safer choice for simple fever and headache. Keep every monitoring blood test appointment. Carry a note of the medicine and its schedule, especially for weekly dosing. Take it after meals and at bedtime when symptoms are worst. Avoid late heavy meals, and raise the head of your bed if symptoms wake you at night.
