Side Effects Of Antibiotics In UTI

Urinary Tract Infection (UTI), one of the most common infections worldwide, is an infection of the urinary system, usually caused by the entry & multiplication of bacteria inside the urinary tract. The urinary tract consists of the Kidneys, Ureters, Bladder, and Urethra. The most common type of UTI is the bladder infection called cystitis, and the infection of the urethra is called Urethritis. Similarly, kidney infection is also a type of UTI. UTIs should be taken care of as early as possible and must be treated well.

Causes Of UTIs

UTIs can affect anyone but they are more common in women. This is because women have a shorter urethra, so it becomes easier for the bacteria to enter the urinary tract. This does not mean that men cannot get UTIs. Men too can get UTIs.

In most cases, UTI is caused by E. coli which is usually found in the intestines. Sometimes these bacteria can travel to urinary tract causing the infection.
Other factors that increase the risk of UTIs are sexual intercourse (the process could move the bacteria from the anal area to the urinary tract), using birth control like spermicides, diaphragms, and condoms, wiping from back to front, holding the pee for a long time, pregnancy, menopause, wearing tight underwear, diabetes or other medical conditions.

Symptoms & Signs of UTIs

  • Painful, burning sensation during urination
  • High frequency and feeling of the urgency of urination, even when there's little urine
  • Cloudy, dark, foul-smelling or bloody urine
  • Discomfort in the lower abdomen
  • Fever, tiredness or shakiness
  • Nausea or back pain

UTI Diagnosis

If you experience any of the above symptoms, contact your doctor for a proper examination. First, the doctor may perform a physical examination and review your symptoms. Then the doctor will ask you to undergo a urine test to confirm the infection and a culture test for identifying the microbes.
If your urine test has a high number of white blood cells, it indicates infection. Urine culture test helps identify the cause of infection and helps the doctor with choosing a treatment.

UTI Treatment

Once the tests are done, your doctor will be able to determine the type of UTI and its treatment.
Treatment includes UTI Medicine like antibiotics and Over The Counter (OTC) pain killers depending upon the condition.

UTI treatment at home to manage the symptoms includes drinking plenty of water, wearing loose and comfortable underwear, wiping front to back, not holding the pee for long, and also including natural supplements.

Antibiotics and Their Side Effects

Antibiotics are medicines that kill the bacteria or stop their growth & multiplication that cause the infection. The best antibiotics for UTI in adults like Sulfamethoxazole/trimethoprim (Bactrim) or Nitrofurantoin (Macrobid) are used in Urinary Tract Infection treatment.
There are different groups or classes of antibiotics that have certain side effects:

  • Affects the digestive system

Many antibiotics affect the digestive system and cause stomach upset with the symptoms like nausea, pain, cramps, vomiting, gas, diarrhea, constipation, etc.

To avoid the above, you can take your antibiotics after food, which helps in reducing these side effects. Also, certain anti-acid tablets or syrups can be taken before meals. Sometimes taking some probiotic supplements along with antibiotics helps in easing the side effects. Including anti-inflammatory foods or following an anti-inflammatory diet might also help.

  • Causes Fever

Sometimes antibiotics can cause fever which is a common side effect. Fever may occur due to allergic reactions to the medication.
Fever is a common side effect due to antibiotics which goes away after 24-48 hours. To help reduce the body temperature certain over-the-counter pain relievers can be taken.

  • Causes Vaginal Yeast Infection

Antibiotics kill good bacteria along with bad bacteria. This causes an imbalance in the vaginal microbiome which otherwise takes care of the vagina and prevents yeast infections from occurring. Antibiotics for urine infection in female causes this side effect.

You may apply vaginal anti-fungal cream, ointments, or even consume oral tablets to reduce the side effects. If the infection gets severe, you should consult the doctor and get the treatment course prescribed.

  • Can Lead to Teeth Decolorisation

Some antibiotics cause discoloration or staining of teeth while consuming them. This is a permanent side effect caused by certain antibiotics. You may ask your doctor for an alternative to avoid this side effect.

  • Can Cause Hearth Burn

It is basically a burning sensation in the upper chest or mid-chest. This is caused due to hyperacidity or acid reflux due to antibiotic intake.

You may take anti-acid anti-gas tablets or syrups along with antibiotics to reduce this side effect. Also, including anti-inflammatory foods help in reducing the burning sensation.

Other side effects include some serious complications like heart problems, blood reactions, severe allergic reactions, seizures, etc. which occur rarely with some antibiotics. You should consult your doctor to see if the side effects don't go away or get worse.

Factors When Choosing an Antibiotic

  • Type of UTI
The dose and the type of antibiotic depend on whether you have an uncomplicated or complicated UTI. A normal urinary tract means uncomplicated and the urinary tract with a problem or disease means complicated.

  • Area of Infection

The treatment also depends upon which part of the urinary tract is infected. Oral antibiotics can be used to treat lower tract UTIs whereas intravenous antibiotics are used for upper Urinary Tract Infections and are put directly into your veins.

  • Severity of Infection

The dosage depends on the severity of the infection. If the infection is severe then a high dosage for a long time is prescribed by the doctor. If the infection is mild, it can be cured with a mild dosage and a short course of UTI medicine. 

  • Allergies

It is better to check if you have any allergies to medicines before choosing an antibiotic so as to avoid any serious complications.

Best Way to Treat UTIs

UTIs when mild can be treated with some home remedies and natural supplements with good results. Including only the best cranberry pills for UTIs is sometimes not enough, hence a good combination of natural supplements might help in such times to help manage UTIs.
Hence, to help with this we have got you a natural UTI management supplement called Chicnutrix Happee that helps relieve the pain caused by UTI, cleanse and protect the bladder, and resist the recurrence of the UTI with its unique triple action formula of cranberry extract, D-mannose, and Ursolia. This Triple Action Formula helps manage UTIs naturally and is a well-balanced formulation created with Swiss Effervescent Technology. It helps prevent and treat UTIs in the following way -

Cranberry extract used in Chicnutrix Happee contains 50% PACs, meaning Proanthocyanidins. Proanthocyanidins (PACs) are nothing but an active ingredient in cranberries which is proven for its health benefits. It helps in preventing the bacteria from sticking to the urinary walls. Bacteria cannot cause infection when they cannot stick to the walls. This way, it helps in cleansing and protecting the urinary tract from infection.

Ursolia, present in Chicnutrix Happee, is a patented & clinically proven ingredient that is rich in Ursolic acid having anti-inflammatory benefits. It helps reduce the discomfort while peeing, like pain & burning sensation. It reduces and prevents inflammatory symptoms caused by the bacteria, Escherichia coli (E. coli). It also helps prevent and protect the urinary lining from the damage caused by inflammatory markers and oxidative stress during UTIs.

D-Mannose is a simple sugar that the body produces in small amounts naturally. D-Mannose prevents infectious bacteria such as E. coli from adhering to the inside walls of the urinary bladder, which then get flushed out.

Chicnutrix Happee is designed to be gentle on the stomach while also acting quickly and gets absorbed with no side effects to support and maintain the health of your urinary tract. To consume Chicnutrix Happee, you simply have to pop one tablet in 250ml of water, let it fizz until it dissolves completely, and say cheers to peeing Happee! While you have an active UTI, take two effervescent tablets daily post any meal for 30 days to help reduce urinary tract infection symptoms. For recurrent UTIs, take one effervescent tablet daily for 30 days after every 3 months to help prevent the infection from occurring again & again.


In conclusion, proactive management of urinary tract infections (UTIs) offers numerous advantages, including the prevention of potentially severe complications. While antibiotics remain a primary treatment option, it is essential to be aware of their potential side effects, heart burn, fever and disruption of the gut microbiome. Fortunately, there are natural approaches to UTI management that can complement antibiotic therapy or be used preventatively, such as increasing water intake, cranberry consumption, and maintaining good hygiene practices. Chicnutrix Happee is your best choice in the fight against UTI.
