Common side effects of metoprolol

These common side effects of metoprolol happen in more than 1 in 100 people. There are things you can do to help cope with them:

Headaches

Make sure you rest and drink plenty of fluids. It's best not to drink too much alcohol. Take paracetamol or ask your pharmacist to recommend a painkiller.

Talk to your doctor if the headaches are severe or do not go away.

Feeling tired, dizzy or weak

If metoprolol makes you feel dizzy or weak, stop what you're doing, and sit or lie down until you feel better. Do not drive, ride a bike or use tools or machinery if you're feeling tired or dizzy. Do not drink alcohol, as it may make your symptoms worse.

Cold hands or feet

Put your hands or feet under warm running water, massage them, and wiggle your fingers and toes. Try not to smoke or have drinks with caffeine in – these can make your blood vessels narrower and restrict your blood flow. Smoking also makes your skin colder. Try wearing mittens (they're warmer than gloves) and warm socks. Do not wear tight watches or bracelets.

Feeling sick (nausea)

Stick to simple meals and do not eat rich or spicy food. It might help to take your tablets after you've eaten.

Stomach pain

Try to rest and relax. It can help to eat and drink slowly and have smaller and more frequent meals. Putting a heat pad or covered hot water bottle on your stomach may also help.

If you're in a lot of pain, speak to your pharmacist or doctor.

Being sick (vomiting)

Take small, frequent sips of water to avoid dehydration. Signs of dehydration include peeing less than usual or having dark, strong-smelling pee.

If you take the  combined pill and you're being sick, your contraception may not protect you from pregnancy. Check the pill packet for advice.

Diarrhoea

Drink plenty of water or squash to prevent dehydration. Signs of dehydration include peeing less than usual or having dark, strong-smelling pee.

If you take the  combined pill and you have severe, watery diarrhoea, or diarrhoea that lasts for more than 24 hours, your contraception may not protect you from pregnancy. Check the pill packet for advice.

Talk to your doctor or pharmacist if the advice on how to cope does not help and a side effect is still bothering you or does not go away.
