Clarithromycin Tablets for Sinusitis

Yes. Clarithromycin is one of the antibiotics recommended by NICE for acute sinusitis if you’re allergic to penicillin. It works against the bacteria that most commonly cause sinus infections.

Doxycycline is another option for people with a penicillin allergy. Learn more about doxycycline for sinusitis.

Most people with sinusitis do not need antibiotics. It is usually caused by a cold virus and clears up within 2 to 3 weeks. Painkillers, saline nasal rinses and decongestant sprays can help in the meantime.

Antibiotics may be recommended if your symptoms have lasted 10 days or more without improving, or if they got better and then worse again. Our prescribers use these clinical criteria during your consultation.

Always follow your prescriber’s instructions and complete the full course of treatment even if you start feeling better. If you finish your course and still feel unwell, speak to your doctor or pharmacist.

• Take one tablet twice a day, about 12 hours apart. For instance, one in the morning and one in the evening.
• Swallow the tablet whole with water. You can take it with or without food.

If you forget to take a dose, take it as soon as you remember, unless it’s nearly time for your next dose. In that case, skip the missed dose. Do not take two tablets at the same time to make up for a forgotten dose.

For adults with sinusitis, the usual dose is 500mg twice a day for 5 days – 10 tablets in total. It’s very important you follow your prescriber’s advice and finish the full course.

Many people start to feel better within a few days of starting treatment. If your symptoms get worse, or do not start to improve after a few days, seek medical advice.

Clarithromycin interacts with a number of medicines, so tell your prescriber about everything you take. In particular, mention:

• Statins, such as simvastatin or atorvastatin
• Warfarin or other blood thinners
• Colchicine, used for gout
• Digoxin or medicines for an irregular heartbeat
• Carbamazepine, used for epilepsy
• Any medicine that can affect your heart rhythm

Your prescriber may ask you to pause some medicines, such as simvastatin, while you take clarithromycin.

Clarithromycin is not usually recommended during pregnancy unless there’s no suitable alternative. If you’re pregnant or could be pregnant, tell your prescriber so they can recommend the safest option for you.

If you’re breastfeeding, small amounts of clarithromycin can pass into breast milk. Let your prescriber know so they can give you the right guidance.

Alcohol does not interact with clarithromycin. But, it’s a good idea to avoid drinking alcohol while you’re unwell, as it can make side effects such as nausea worse.

Clarithromycin should not usually affect your ability to drive. But, some people feel dizzy or confused. If this happens, do not drive or operate machinery until you feel better.

Clarithromycin does not affect the contraceptive pill directly. It also does not affect the emergency contraceptive pill. But, clarithromycin can cause vomiting or diarrhoea in some people.

If you’re vomiting or have diarrhoea for more than 24 hours, this may prevent your contraceptive pill from working. To find out what to do, read the patient information leaflet that comes with your contraceptive medication, speak to your doctor, or visit the NHS website for guidance.

Rest, drink plenty of fluids and take paracetamol or ibuprofen if they’re suitable for you. Salt water nasal rinses, steam inhalation and sleeping with your head raised can also help ease a blocked nose and pressure.

Get urgent medical help from a GP or NHS 111, or go to A&E, if you have:

• Swelling or redness around your eyes
• Changes to your vision, such as double vision
• A severe headache that does not go away, or pain in your forehead with swelling
• Confusion, drowsiness or a stiff neck
• A very high temperature or you feel very unwell

These can be signs of a more serious infection that needs prompt assessment rather than waiting for a delivery.
