About Zithromax
Zithromax vs azithromycin - What is the difference?
Zithromax is a branded medication manufactured by Pfizer. It contains azithromycin, an antibiotic which kills chlamydia bacteria. Zithromax tablets therefore work in the same way as generic azithromycin but comes in branded packaging. Branded medicines can be slightly more expensive than generic medication. Please note, product packaging may differ from the image above.
Both medicines are equally effective in treating chlamydia. Which medication you get can vary depending on where you buy your medication. While some pharmacies may stock Zithromax, others may only supply the generic version.
How to take Zithromax
You should take Zithromax without food, at least one hour before or two hours after you eat. When you take it for chlamydia, you are prescribed a dose of 1g to be taken as one single dose. It is very important that you take the full dose as advised.
If you accidentally take more Zithromax than you have been prescribed, seek medical help immediately.
Zithromax Dosage
The standard dose for treating chlamydia infections is 1g Zithromax. Depending on the dosage of your tablets, you may need to take more than one tablet at the same time.
Can I drink alcohol with Zithromax?
There is no known interaction between Zithromax and alcohol.
How long does Zithromax take to cure chlamydia?
It can take up to one week for the medication to kill all chlamydia bacteria. During this time, you should avoid sex to prevent passing the infection to your partner. If you decide to have sex during this time, make sure you use a condom to reduce the risk of spreading the infection.
Can I take Zithromax when pregnant or breastfeeding?
If you need to take Zithromax during pregnancy or while breastfeeding, speak to your local GP. Your GP will assess whether the tablets are suitable for you. It may be possible for you to take Zithromax if your GP approves.
Who can take it
You mustn’t take Zithromax if you are allergic to any of the ingredients. The same applies, if you are allergic to any antibiotics which are very similar to azithromycin, such as erythromycin or any other macrolide or ketolide antibiotic.
ZIthromax is a prescription-only medication and your prescribing doctor will assess whether it is suitable for you before issuing a prescription.
Make sure you let your doctor know if you are currently trying for a baby, pregnant or breastfeeding. Please note, that Superdrug Online Doctor won’t be able to supply chlamydia treatment to women who are pregnant or breastfeeding. You will need to speak to your local GP if this applies to you.
