Amoxicillin for Sinus Infection: Dosage, Benefits, and Safety Tips

Introduction

Sinus infections, also called sinusitis, affect millions of people each year. They cause uncomfortable symptoms like facial pain, nasal congestion, headaches, and thick mucus. While some sinus infections clear up on their own, bacterial sinus infections often require antibiotics. Amoxicillin is one of the most widely prescribed antibiotics in Online Pharmacy for this condition. In this article, we’ll explain how Amoxicillin works, the right dosage, benefits, possible side effects, and important precautions.

What is Amoxicillin?

Amoxicillin is a penicillin-type antibiotic that works by killing bacteria responsible for infections. It prevents bacteria from forming protective cell walls, making it easier for your immune system to clear the infection. Doctors commonly prescribe Amoxicillin for conditions like:

• Respiratory infections
• Ear infections
• Skin infections
• Urinary tract infections
• Bacterial sinusitis

How Amoxicillin Helps in Sinus Infections

Most sinus infections are viral, but if your symptoms last more than 10 days or get worse after initial improvement, your doctor may suspect a bacterial cause. Amoxicillin helps by:

• Targeting bacteria commonly responsible for sinus infections (like Streptococcus pneumoniae and Haemophilus influenzae).
• Reducing inflammation and infection inside the sinuses.
• Relieving symptoms such as nasal blockage, pressure, and facial pain.

Recommended Dosage for Sinus Infection in Drugmart

The exact dosage depends on age, weight, and severity of infection. Always follow your doctor’s advice, but general guidelines include:

• Adults: 500 mg every 8 hours, or 875 mg every 12 hours, usually for 7–10 days.
• Children: Dosage is based on weight (typically 45 mg/kg/day divided into two or three doses). A liquid suspension is often prescribed.
• Severe cases: Higher doses or extended courses may be necessary.

Important: Do not stop taking Amoxicillin early, even if you feel better. Stopping too soon can allow bacteria to survive and cause the infection to return.
