Medicines for Sinus Infections: What Actually Helps?

Most sinus infections get better with medicines such as painkillers, decongestants, saline sprays, and nasal steroid sprays. Antibiotics can only be helpful in extremely rare cases when symptoms clearly point to a bacterial infection. For most people in the UK, the best relief comes from easing pressure, reducing swelling, clearing mucus, and managing pain, not from antibiotics.

Sinus infections occur when the spaces behind your nose become swollen and blocked. This causes pressure, headaches, a blocked nose, thick mucus, and tenderness around the face. Many people search for “the best medicine for sinus infection,” but the real solution depends on which symptoms you want to treat. Below is a clear breakdown, written simply and based on how UK doctors, pharmacists and NHS services guide patients.

What Actually Helps a Sinus Infection? (UK-Based Practical Guide)

1. Painkillers for Pressure and Headaches

Most people feel sinus pressure around the eyes, nose, and forehead.
Medicines that help:

• Paracetamol – gentle on the stomach and reduces pain.
• Ibuprofen – reduces pain and swelling.
  These options don’t unblock the nose, but they make the infection easier to cope with while your body heals.

2. Decongestants to Reduce Blocking

A blocked nose is one of the hardest parts of a sinus infection. Decongestants shrink the swollen tissues inside the nose so air can flow again.
Common types include:

• Pseudoephedrine tablets
• Nasal decongestant sprays
  These work quickly, but nasal decongestant sprays should not be used for more than a few days, as extended use can make the blockage worse.

3. Steroid Nasal Sprays to Reduce Swelling

Steroid nasal sprays help calm the inflammation inside the sinuses.
They are especially useful if:

• You have allergies
• Symptoms last longer than 10 days
• Your infection keeps coming back
  These sprays take a few days to work but give strong relief when used each day correctly.

4. Saline Sprays and Rinses

Saline sprays wash away thick mucus and help the nose feel clearer.
This is one of the safest options because it:

• Hydrates dry nasal passages
• Helps move trapped mucus
• Can be used multiple times a day
  Saline is also very helpful if you cannot use decongestants.

5. Antihistamines for Allergy-Linked Sinusitis

If your sinus problems happen during pollen season or after dust exposure, antihistamines can help reduce sneezing, itching, and watery eyes.
They do not cure a sinus infection, but they help stop allergy symptoms that make sinus swelling worse.

6. Antibiotics (Only When Needed)

Most sinus infections are caused by viruses, not bacteria. Viral infections do not improve with antibiotics.
Doctors in the UK recommend antibiotics only if:

• Symptoms last more than 10 days
• You have very severe pain
• You have a fever
• Yellow-green mucus continues and gets worse
  Even when used, antibiotics help only a small number of people with true bacterial sinusitis.

Final Takeaway

Sinus infections feel heavy and uncomfortable, but most improve without antibiotics. The medicines that truly help focus on reducing swelling, easing pressure, thinning mucus, and treating any allergy-linked triggers.
With the right mix of pain relief, nasal sprays, saline rinses, and supportive care, most people recover smoothly and feel normal again within days.

1. What medicine works best for a sinus infection?
The best medicine depends on your symptoms. Most people feel better with painkillers, decongestants, saline sprays, or steroid nasal sprays. These help reduce pressure, swelling and blockage. Antibiotics are not usually needed unless a doctor believes the infection is bacterial.

2. Do sinus infections always require antibiotics?
No. Most sinus infections in the UK are viral, and viral infections don’t improve with antibiotics. A GP may consider antibiotics only if symptoms are severe, last longer than 10 days, or keep getting worse.

3. How can I quickly relieve sinus pressure?
Painkillers, warm compresses, steam inhalation, and decongestants can help. Saline sprays also make a big difference by loosening thick mucus.

4. What should I take if I have a blocked nose?
Decongestants work well for short-term relief. Saline sprays are safe to use more often and help gently clear mucus. 

5. Are steroid nasal sprays safe?
Generally, yes, they are safe, but only when used as directed. The steroid nasal sprays work by reducing swelling inside the nose, and can take a few days for the visible results.

6. Can antihistamines help sinus infections?
They help only if allergies trigger your symptoms. Antihistamines don’t cure a sinus infection, but they can reduce sneezing, congestion, and irritation caused by allergens.

7. How long does a sinus infection usually last?
Sinus infection can last up to 10 days, but for some, it can last up to 3 weeks. A GP should be consulted if the symptoms remain the same beyond that.

8. When should I worry about a sinus infection?
You should seek professional medical advice if you have a high fever, swelling around the eyes, severe headaches, symptoms lasting more than 3 weeks, or sinus infections that keep coming back.

9. Can I treat a sinus infection at home?
Yes. Pain relief, saline sprays, rest, drinking plenty of water, warm compresses, and gentle steam can all help your body recover.

10. What makes sinus infections feel worse?
Thick mucus, blocked nasal passages, cold air, dry environments, and allergies can all intensify symptoms. Medicines that reduce swelling and clear mucus usually offer strong relief.
