Trichomoniasis is another type of sexually transmitted infection. This is not life-threatening but can cause anxiety and lead to other complications. In women, symptoms often include abnormal vaginal discharge, foul odor, and irritation of the genital area with pain during intercourse. In men, symptoms are usually mild and may consist of a clear, mucus-like discharge, itching, or pain in the urethra.
When you have these symptoms, don’t ignore them and see a doctor immediately. When symptoms are detected early, they can be treated promptly.
Important facts about Trichomoniasis
Trichomoniasis is a type of sexually transmitted infection caused by a protozoan parasite known as Trichomonas vaginalis. It can occur in both men and women but is more commonly found in women.
Trichomoniasis causes severe itching in the vaginal area due to the Trichomonas vaginalis parasite, which is a relatively large protozoan. It damages the squamous epithelial lining of the vagina, leading to significant inflammation.
What causes a trichomoniasis?
Trichomoniasis is caused by an infection with the protozoan Trichomonas vaginalis. It primarily spreads through sexual contact. The incubation period for this disease is approximately 5 to 28 days in female patients.

Treatments for Trichomoniasis
For treating Trichomoniasis, doctors typically prescribe antibiotics. Most symptoms improve within 2-3 days after starting treatment. It’s important for both the infected person and their partner to receive treatment simultaneously and to follow the doctor’s self-care instructions. If symptoms persist, a follow-up visit to the doctor is necessary.
Medications for Trichomoniasis
- Women: Metronidazole 500 mg, taken twice daily for 7-10 days.
- Men: Metronidazole 2 grams, taken as a single dose.
Note: Do not self-medicate. It is essential to get a proper diagnosis and prescription from a doctor.
Seeing a doctor is better than self-medicating. Taking the correct medication ensures effectiveness and reduces the risk of drug resistance, allergic reactions, and the need for costly repeated treatments.
Complications

May spread to the urethra and bladder, causing inflammation.
- Can lead to pelvic infections.
-
Pregnant women are at risk of preterm delivery.
Protections for Trichomoniasis
- The most effective prevention is to avoid sexual intercourse. If this is not possible, always use condoms during sexual activity.
- Avoid frequently changing sexual partners.
- If you and your partner are diagnosed with Trichomoniasis, seek medical attention promptly for diagnosis and treatment. This will help prevent reinfection and the spread of the infection to others.
Self-care for TRICHOMONIASIS
- Take antibiotics as prescribed by your doctor, completing the full course even if symptoms resolve.
- Avoid sexual intercourse until you and your partner have completed treatment and symptom-free for at least 2 weeks.
- Avoid alcohol while taking medication.
