You need to take one nitrofurantoin 100mg dose in the morning and one in the evening. You should aim to take the tablets at the same time every day. The course will last for three days. The tablets need to be swallowed whole with a drink of water.
You may feel better before you have completed the course of antibiotics. However, it is important that you finish your course as advised, even if you feel better. If you stop taking your antibiotic early, the bacteria which cause cystitis can become resistant to the medication. If this happens, your infection will return and it can be very difficult to treat. Taking your tablets twice daily for three days will prevent this from happening.
Nitrofurantoin and Alcohol
Nitrofurantoin and alcohol do not interact. Moderate alcohol consumption will not reduce the effect of nitrofurantoin. However, it is not advisable to drink alcohol while suffering from a bladder infection. Herbal teas and water are more suitable and drinking plenty of nonalcoholic fluids will help you get rid of the infection.
