Gyne-Lotrimin cream (Clotrimazole)

Clotrimazole Vaginal Cream is an antifungal medicine primarily used to treat vaginal yeast infections caused by Candida species. It works by inhibiting the growth of fungi, thereby alleviating symptoms such as itching, burning, and discharge associated with these infections.

What Is Clotrimazole Vaginal Cream?

Clotrimazole is an azole antifungal effective against various fungal infections, particularly vulvovaginal candidiasis. It is available in cream form for intravaginal use, typically administered at bedtime for a specified duration, depending on the concentration.

A yeast infection is a common type of vaginal infection. Your doctor may call it candidiasis. This condition is caused by an organism called Candida, a yeast type. Healthy women usually have this yeast on the skin, in the mouth, in the digestive tract, and in the vagina. At times, the yeast can increase. The infection is sometimes called yeast (Candida) "overgrowth." Some women may have a yeast infection on the skin outside the vagina (vulva) associated with the vaginal infection.

A yeast infection can occur at any age. It is most common during the childbearing years. Women who are pregnant or diabetic, taking antibiotics, birth control pills, or steroids, or who have a weakened immune system are more likely to get repeated yeast infections.

Symptoms of a Vaginal Yeast Infection

• vaginal itching (ranging from mild to severe);
• a clumpy vaginal discharge that may look like cottage cheese;
• vaginal soreness, irritation, or burning;
• rash or redness on the skin outside the vagina (vulvar irritation).

Forms and Dosage of Clotrimazole

How to Use Clotrimazole for Vaginal Application

• Wash your hands before use.
• Use the provided applicator to insert the cream as high as possible into the vagina, preferably at bedtime.
• Avoid using tampons, douches, spermicides, or other vaginal products during treatment.
• To reduce irritation and improve effectiveness, consider avoiding sexual intercourse during treatment.

What Do I Do if I Miss a Dose?

If you forgot your dose, use it as soon as you remember. If it is close to your next dose, skip the missed dose and return to your schedule. Do not use two doses at the same time.

Prescription

Clotrimazole Vaginal Cream is available over the counter (OTC) in many regions, meaning a prescription is not typically required for purchase. However, it is advisable to consult a healthcare professional if this is the first occurrence of symptoms or if symptoms persist.

Clinical Pharmacology

Mechanism of Action

Clotrimazole inhibits the biosynthesis of ergosterol, a crucial component of the fungal cell membrane, disrupting membrane function and inhibiting fungal growth.

Pharmacokinetics

When administered vaginally, only a small proportion is absorbed systemically (about 5% to 10%). Therapeutic concentrations can persist locally for up to several days after application.

Important Safety Information

Possible side effects include vaginal burning, irritation, and abdominal cramps. Seek medical attention if severe allergic reactions occur or symptoms do not improve after treatment.

Latex contraception notice: clotrimazole cream can damage latex (e.g., condoms or diaphragms) and may reduce their effectiveness. Use alternative contraception during treatment and for a short period after the last dose (follow the product label/leaflet for the exact duration).

If swallowed, call a doctor or poisons information centre right away.

Contraindications to Clotrimazole

1. Allergy to clotrimazole or any component of the product.
2. Unverified vaginal infection: do not self-treat if you have never had a doctor-confirmed yeast infection.
3. Eye contact: avoid contact with eyes due to risk of severe irritation.
4. Pregnancy and breastfeeding: use only when needed and discuss risks/benefits with a healthcare professional.

Side Effects

• Local irritation (burning, redness, swelling).
• Abdominal discomfort.
• Allergic reactions (rash, hives, swelling, breathing difficulty) — seek urgent help.

Interactions of Clotrimazole Cream with Other Medicines

Due to minimal systemic absorption, clinically significant interactions are uncommon. However, caution may be needed with some medicines in specific clinical situations.
