3 min read 14-03-2025

Metronidazole vaginal gel is a common medication prescribed to treat bacterial vaginosis (BV) and other vaginal infections. While generally safe and effective, it's crucial to understand the potential side effects. This article provides a comprehensive overview of these side effects, helping you make informed decisions about your treatment.

Common Side Effects of Metronidazole Vaginal Gel

Most women experience minimal side effects. However, some common, usually mild, reactions can occur:

Burning or stinging sensation: This is often temporary and subsides as treatment continues.
Vaginal irritation: Similar to burning, this can manifest as itching or discomfort.
Changes in vaginal discharge: You might notice a change in color, consistency, or odor. This is often related to the infection itself resolving, but contact your doctor if you have concerns.
Headache: A fairly common side effect, usually mild and short-lived.
Metallic taste: Some women report a temporary metallic taste in their mouth.

These side effects typically resolve on their own as the medication is discontinued. If they persist or worsen, consult your doctor immediately.

Less Common but More Serious Side Effects

While less frequent, certain side effects warrant immediate medical attention:

Allergic reactions: These can range from mild skin rashes to severe reactions like hives, swelling, or difficulty breathing. Seek immediate medical help if you experience an allergic reaction.
Severe abdominal pain: This could indicate a more serious problem and requires prompt medical evaluation.
Seizures: While rare, seizures are a potential side effect. Seek immediate medical help if this occurs.
Dark urine or pale stools: These can be signs of liver problems and require immediate medical attention.
Yellowing of the skin or eyes (jaundice): Another indication of liver issues, requiring immediate medical evaluation.

Q: How long do side effects of metronidazole vaginal gel last?

The duration of side effects varies. Most common side effects, like burning or irritation, should resolve within a few days of finishing treatment. If they persist longer, contact your healthcare provider.

Q: What can I do to minimize side effects?

While you can't eliminate all side effects, here are some tips:

Follow instructions carefully: Use the medication exactly as prescribed.
Avoid alcohol: Combining metronidazole with alcohol can lead to unpleasant side effects like nausea and vomiting (Antabuse effect).
Use absorbent pads: These can help manage any increased vaginal discharge.
Wear loose-fitting cotton underwear: This promotes airflow and can help reduce irritation.
Avoid douching: Douching can disrupt the vaginal flora and worsen irritation.

When to See a Doctor

Contact your doctor immediately if you experience any severe or persistent side effects, or if your symptoms worsen during treatment. Early intervention can help prevent complications.
