Erythromycin Dosage and Directions
How to take Erythromycin
Always take Erythromycin exactly as instructed by your doctor. Read the patient information leaflet thoroughly and ask your doctor or pharmacist for advice if you are still not sure.
Swallow Erythromycin tablets whole with a drink of water. Do not crush or chew them.
Try to take the tablets with food.
The recommended daily dose is 250mg - 1,000mg, to be taken four times a day. In some cases you may be instructed to take it twice a day. The dose might be lower for children.
Try to space your doses evenly throughout the day, such as taking it first thing in the morning, at lunchtime, in the late afternoon, then at bedtime. It is best to leave about 4 hours between each dose.
What if I take too much?
If you take more Erythromycin than you were supposed to, you are unlikely to come to any harm. However, you may be at risk of temporary side effects, such as hearing loss, vomiting, an upset stomach or diarrhoea.
Speak to your doctor or pharmacist if you become worried or if you or your child has taken more than one extra dose.
What if I forget to take it?
If you forget to take a dose, take it as soon as you remember. If it is almost time for your next dose, just skip the tablets you missed and continue to take the medication as normal.
Never take a double dose to try and make up for missing a previous one.
To ensure you do not forget to take Erythromycin, try to take it at the same times every day. Some people find it helps to set an alarm as a reminder.
Keep this medicine out of the sight and reach of children.
Do not store in conditions above 25C. Store the tablets in the original packet and keep it closed.
Do not keep using this medicine after the expiry date, which can be found on the packaging. The expiry date refers to the last day of the stated month.
