  • Overview

    What is Macrobid?

    Macrobid 100mg is an antibiotic drug used to treat bladder infections (also known as UTIs or acute cystitis). It is a course of medicine that is taken orally for a specified time period (usually three days to one week).

    Macrobid for UTI

    Macrobid is solely for the treatment of UTI infections. It hinders the growth of bacteria in the bladder, which causes the infection. When bacteria’s growth is stunted, it cannot continue infecting the bladder. Once the bacteria disappear, the infection is gone, and your symptoms should go.

    Don’t take Macrobid tablets for any other kind of infection, such as a kidney or liver infection. These types of illnesses require very different treatments. If you think that you have a kidney or liver infection, or any other kind of infection, consult with your doctor.

    How long does Macrobid take to work?

    Most people take Macrobid for seven days, although many people find that their symptoms are relieved in 1-3 days. However, it is essential to take the medication exactly as prescribed, even if your symptoms disappear.

    Macrobid and alcohol

    Many antibiotics cannot be taken with alcohol - it can cause some tablets to stop working or increase the risk of side effects.

    However, Macrobid isn’t one of these; some people can still enjoy limited alcohol while taking the tablets.

    There are some crucial things to consider when drinking and taking Macrobid. Even if it’s just one glass of wine, alcohol will dehydrate you, which could exacerbate your cystitis symptoms.

    Furthermore, alcohol and hangovers can mimic side effects, like nausea or headaches. It’s important to know whether your side effects are due to the tablets or not, so alcohol could confuse matters.

    If you have any other medical conditions or are taking other tablets while on your course of Macrobid, you should also avoid drinking alcohol.

    That being said, most doctors agree that alcohol doesn’t stop Macrobid from working, and the medical advice for Macrobid and alcohol is unclear.

    Macrobid pregnancy

    Macrobid should be avoided as much as possible during pregnancy, although some doctors may prescribe it to women in their early stages who have no other option for UTI treatment. Speak to your doctor if you are less than 36 weeks pregnant and are considering buying Macrobid.

    If you are close to the end of your pregnancy or in labour, Macrobid should be completely avoided. This medication can cause hemolytic anaemia, a rare blood condition, in your fetus, which can cause issues for them after they are born.

    You should also take care when taking this tablet whilst breastfeeding. This medication has been found in the breast milk of women taking it, and it can cause side effects in young infants or babies with a certain genetic condition. Consult with your doctor if you are considering taking Macrobid tablets and are breastfeeding.

    Macrobid reviews

    Many Macrobid reviews are very positive, commenting on how it clears up UTIs very quickly (some people report as soon as 5 hours after the first dose) and efficiently, and provided the full course is taken, it doesn’t return. Most reviewers recommend eating Macrobid with food - a meal, if possible.

    Some people report experiencing mild side effects, such as nausea and headaches while taking Macrobid 100mg, but they generally report that these side effects clear up fairly quickly.

  • Directions

    Macrobid dosage

    You should take Macrobid 100mg by mouth while eating. The exact dosage varies depending on you and your infection’s severity, but most people take Macrobid twice daily for three days to one week.

    It’s best if you evenly space your dosages - for example, if you take one tablet every 12 hours, you could take one at 8 am and one at 8 pm. Taking the tablet at the same time each day also helps you remember each dose.

    You should take the medication until you have finished the entire course, even if you start to feel better. This is essential because Macrobid works at both removing the bacteria and ensuring that it stays away. Stopping the course prematurely could encourage the bacteria to grow again, resulting in the infection recurring.

    If you miss a dose of your Macrobid course, take the tablet as soon as you can. However, if you are closer to the next dose, just skip the initial missed dose and resume the course with the next tablet. You shouldn’t ever take a double dose of Macrobid - this increases the possibility of side effects.

    Macrobid is a valuable cure for UTIs and their unpleasant symptoms. If you want to buy Macrobid, Cloud Pharmacy offers next-day delivery.

  • Side Effects

    Macrobid side effects

    As with all medicines, there are a few common and less common side effects when you take Macrobid. Ensure that you are fully aware of these potential side effects before you buy Macrobid, and speak to a doctor or pharmacist if anything worries you.

    Common side effects

    • Slight nausea and headache. If either of these conditions worsens or doesn’t go away, speak to a doctor or pharmacist
    • Discolouration in your urine. Your urine may change colour to dark yellow or brown while taking Macrobid tablets. This is generally normal; however, if your urine is dark brown, keep an eye out for other side effects
    • Dark brown urine can indicate liver issues or anaemia, which is a rare side effect of this drug. Seek medical care immediately if you have dark brown urine and any of the following symptoms: yellow eyes/ skin, fast heartbeat, unexplained fatigue, persistent nausea, stomach pain or vomiting

    Rare but severe side effects

    • Vision changes or eye pain
    • Mood changes
    • Severe headaches
    • Fever
    • Easy bruising or bleeding
    • Persistent and unexplained sore throat
    • Diarrhoea, cramping, or blood or mucus in your stool (this can indicate a rare intestinal condition) if you experience these gastric symptoms, do not take diarrhoea medication as it may worsen your condition

    If you encounter any of these, speak to your doctor immediately.

    If you feel the following side effects, you should seek emergency care (ring 999 or go to A&E and make sure that you tell them you are taking Macrobid tablets):

    • Hand or feet tingling or numbness
    • Muscle weakness
    • Chest pain
    • Shortness of breath
    • Bluish skin
    • Severe joint pain

    These symptoms can indicate a serious lung problem, which can be fatal if not treated. Generally, these symptoms only occur in people who take Macrobid long-term. However, it can very rarely cause issues in people who take a short course of the medication.

    If you take Macrobid regularly or for longer than prescribed, you may be at a heightened risk of thrush or yeast infections. Symptoms include white patches in your mouth and unusual vaginal discharge. If you experience these, speak to your doctor.

    Allergic reactions to Macrobid are very rare. However, if you experience any severe dizziness, unusual itching, swelling (particularly in the tongue, throat, or face), or an unexplained rash, seek emergency medical treatment.

    If you encounter any worrying symptoms that are not listed above, contact your doctor.

    Macrobid and certain conditions

    People with particular conditions should avoid Macrobid. If you have any of the following chronic conditions, make sure that you discuss the risk of side effects with your doctor or pharmacist before you buy Macrobid.

    • Kidney disease
    • Liver disease
    • Lung disease
    • Blood problems
    • Frequent numbness or tingling in arms and joints
    • Deficiencies in any vitamins, particularly vitamin B
    • Allergies to any medication (there may be inactive ingredients in Macrobid)
      Diabetes (type 1 and type 2)
    • Eye disorders
    • Any other serious chronic health conditions that you are concerned about

    Older adults have a higher risk of developing side effects. This is because we typically experience declined kidney function as we age, and the kidneys are an essential organ for the processing of Macrobid.

    Side effects are still rare for this age group, but proceed with more caution - and if you know that you have kidney issues, it’s essential that you speak to your doctor before taking Macrobid tablets.

    Macrobid drug reactions

    Check with your healthcare professional if you take any other medication, including herbal medicine or non-prescription drugs. Most drugs will not react with Macrobid, but it’s essential to make a medical professional aware of any potential interactions.

    You should alert your doctor immediately if you are taking medications for the treatment of gout, as some of these medicines are known to react with Macrobid 100mg.

    Consult with your doctor if you are offered any vaccinations while taking Macrobid, including the Coronavirus vaccine. The medication can cause some bacterial vaccines to function differently.

  • FAQ

    • What is Cystitis?

      Cystitis is the medical term given to inflammation of the bladder. It is commonly caused by a bacterial infection and known as a Urinary Tract Infection(UTI).

    • What are the symptoms of Cystitis?

      The signs and symptoms of Cystitis include:

      • Persistent urge to pass urine
      • Burning sensation when urinating
      • Discomfort in pelvic area
      • Blood in the urine (hematuria)
      • Passing of cloudy or strong-smelling urine
    • Is Cystitis common?

      Women get cystitis more often than men because their anus (back passage) is closer to their urethra, and their urethra is much shorter, which means bacteria may be able to get into the bladder more easily.

      The urethra is longer in men than women, this makes it harder for bacteria to travel up to the bladder. Men can also get cystitis but this is significantly less common and they must visit their GP to rule out other serious conditions such as urinary obstruction, enlarged prostate or tumours.

    • How can I prevent Cystitis?

      If you suffer from cystitis regularly, there are measures you can apply to stop it reoccurring. These included but are not limited to:

      • Stay Hydrated: drink plenty of water
      • Urinate Frequently: if you feel the urge, do not delay passing urine.
      • Wipe from front to back: this is in reference to wiping after a bowel movement. It prevents the bacteria from faeces spreading to the vaginal area.
      • Use Non-Perfumed products: use perfume free or plain feminine products in the genital area. 
      • Pass Urine as soon as possible after sexual intercourse: drinking lots of water helps flush bacteria
      • Gently wash the skin around genital area: do this daily but take care to not use harsh soaps or wash too vigorously in these delicate areas.
    • Is Cystitis contagious?

      Cystitis is a bacterial infection, however it cannot be transmitted like the common cold. Cystitis is not contagious; you do not need to worry about passing it on to others.

    • What is the treatment for Cystitis?

      The treatment for cystitis depends on it's severity.

      For mild infections, you can make the urine less acidic by avoiding carbonated drinks and drinking lots of water. There are also simple sachets such as Cystopurin, Canesten Oasis, Potassium Citrate mixtures.

      For more troublesome infections, the bacterial infection can be treated using antibiotics such as Trimethoprim or Macrobid (Nitrofurantoin). These are both available through our online pharmacy


    • What is the best antibiotic for Cystitis?

      For any bacterial infection, the best antibiotic is dependent on what bacteria is causing the infection. The most common type of bacteria for uncomplicated urinary tract infections is E-Coli.

      In the UK, NICE determine guidelines for prescribing using an evidence-based approach. 

      The antibiotics which are given to treat this bacteria are Trimethoprim or Nitrofurantoin. If your symptoms do not improve after completing a course of these antibiotics, it is imperative that you see your GP to have a urine analysis carried out. 


    • Can you buy treatment over the counter for Cystitis?

      There are sachets containing Sodium Bicarbonate or Potassium Citrate which are available over the counter. These alleviate the symptoms however they simply reduce the acidity of urine and their effectiveness lacks sufficient evidence.
