Tinidazole is an oral antibiotic used to treat certain bacterial infections, including bacterial vaginosis (BV). BV is an infection caused by an overgrowth of harmful bacteria in the vagina. Tinidazole belongs to a group of medicines called nitroimidazoles. It works by killing the organisms that can cause infection.
Tinidazole is approved by the FDA. At SpeedyHealth, our doctors are able to prescribe Tinidazole for BV after you complete an online consultation.
Tinidazole works by interfering with the DNA of harmful microorganisms. Once it is inside the body, it causes the DNA strands to break, which stops the organism from copying its DNA or making new cells. This damage ultimately kills the bacteria or protozoa and treats the infection.
There are many benefits of using Tinidazole to treat BV:
Tinidazole is effective against both bacteria and protozoa. It treats a wide range of infections apart from BV, such as:
The drug is quickly absorbed in the body and begins acting on the infection soon after taking the first dose.
Tinidazole has a long half-life which means it stays active in the body for longer. This reduces the need for frequent doses, as such, the tablet only needs to be taken once daily.
Tinidazole has been proven to be effective in treating bacterial vaginosis.
In 21 clinical studies looking at how well Tinidazole works for treating BV, researchers found that Tinidazole was very effective in getting rid of the signs and symptoms of BV compared to a placebo.
The cure rate for patients treated with Tinidazole at a dose of 1g daily for 5 days was 91%.
Tinidazole is an effective option for many women suffering from BV however, it may not be suitable for everyone.
Tinidazole tablets are suitable for adult women suffering from bacterial vaginosis who prefer using a tablet.
Do not use this medicine if you are allergic to Tinidazole or other nitroimidazole medicines. This medicine is not suitable for pregnant women, especially those during the first trimester of pregnancy.
Speak to your doctor before taking this medicine if you:
To treat BV, the recommended dose is 1g (2 of the 500 mg tablets) once a day for 5 days.
Take this medicine by mouth with food and a full glass of water. Make sure you finish the entire course of this medicine, even if you start to feel better. If you stop taking Tinidazole too soon or skip doses, your infection may not be completely cured and the bacteria may become resistant to antibiotics.
If you miss a dose, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and take the next dose at your usual time. Do not take double or extra doses.
This medicine starts to work as soon as you take the first tablet. The tablets are quickly and fully absorbed into the body after the first dose. The peak concentration of the medication is reached approximately 1.6 hours after taking the dose.
Your symptoms should improve within a few days of taking this medicine, and BV should completely resolve within 5 days of taking the treatment. However, if your infection worsens or your symptoms persist, speak to your doctor.
Take these tablets for 5 days in a row. Make sure to finish the entire course, even if you start feeling better. If you stop early, the infection might not go away completely or may return.
It’s important to make certain lifestyle changes to ensure this medicine remains effective:
Stay hydrated
Drink plenty of water to stay hydrated, especially if you experience side effects like nausea or diarrhea.
Maintain good hygiene
After using the toilet, wipe from front to back to prevent bacteria from the rectum from spreading to the vaginal area.
Wear breathable underwear
Wear underwear made from breathable fabrics to help keep the vaginal area dry. Avoid tight, synthetic fabrics, as these can trap heat and moisture and promote bacterial growth.
Avoid harsh soaps
