Cranberry supplements, such as the Solgar Cranberry Extract, are often used to support urinary tract health. Cranberries contain bioflavonoids and vitamin C, which can contribute to overall health.

However, it is important to know that if you suspect you have a bladder infection, we recommend contacting your GP. These supplements are intended as support and do not replace medical treatment.

It sounds like you're going through a tough time, and we understand how frustrating recurrent urinary tract infections can be. We can offer you some advice and suggest certain products you might consider. 
We recommend starting with a good probiotic specifically for women, such as:

You can take this probiotic in the final phase of your antibiotic course, use it as a course, and after a while, you might switch to a lighter version of probiotics.

Additionally, we suggest D-Mannose

For long-term use: take 2 capsules twice daily. 
For extra support: take 3 capsules 2 to 3 times daily.

Due to the Claims Regulation Act, unfortunately, we're unable to delve deeper into the advice here. 
And of course, to prevent a urinary tract infection; go to the toilet as soon as you feel the urge to urinate and completely empty your bladder. 
Good hygiene is important, and as a woman, remember to urinate immediately after intercourse.
Drink at least one and a half litres of water every day. 

Of course, we also recommend contacting your GP or a healthcare professional for advice on your specific situation. Please note that these suggestions are not a substitute for medical advice. Take good care of yourself, and we hope you recover quickly.

It seems possible, but always consult your GP or pharmacist first. There have never been any reported interactions, but that does not mean you should not be cautious.

We advise against the use of Cranberry extract during pregnancy and lactation as it has not been researched and no safety data is available. Cranberry juice can be taken in moderation, but an extract is too concentrated and potent.
