usually in the morning. Each capsule contains 408mg of lymecycline.
When you take it for other infections, follow your doctor or pharmacist’s instructions.

Swallow the capsule whole, along with a glassful of water.
Like all medicines, lymecycline can cause side effects, although not everyone gets them.
Common side effects
These common side effects happen in more than 1 in 100 people. Keep
taking the medicine, but tell your doctor if the side effects bother you
or don’t go away:
- feeling sick
- stomach pain
Serious side effects
Serious side effects are rare.
Stop taking lymecycline and tell a doctor straight away if you get:
- yellow skin or eyes (this can be a warning sign of liver problems)
- your skin becomes very sensitive to the sun
Serious allergic reaction
It’s possible to have a serious allergic reaction (anaphylaxis) to lymecycline.
What to do about:
- feeling sick – try taking lymecycline with or after
food to see if that helps ease feelings of sickness. It may also help
if you avoid rich or spicy food while you’re taking this medicine.
- stomach pain – try to rest and relax. Putting a hot
water bottle on your tummy may help. If you are in a lot of pain, speak
to your pharmacist or doctor.
- diarrhoea – drink plenty of water or other fluids if you have diarrhoea. It may also help to take an oral rehydration drink to prevent dehydration. You can buy sachets of powder from a pharmacy which you mix with water. Don’t take any other medicines to treat diarrhoea without speaking to a pharmacist or doctor.
- headaches – make sure you rest and drink plenty of fluids. Don’t drink too much alcohol. Everyday painkillers, such as paracetamol and ibuprofen, are safe to take with lymecycline.
Lymecycline is not normally recommended for women who are pregnant or
breastfeeding. Ask your doctor if there’s another safer antibiotic that
you can take.
