Brief Answer: Yes you can take a second dose. Detailed Answer: Hello, Thanks for trusting us with your health concern. The continuous sneezing that you are having is likely to be due to allergic rhinitis. Taking another dose of sinarest might be helpful in decreasing the symptoms to some extent. There are some general measures that can help you in reducing the problem- 1. Avoid dust, excessive humidity, sudden change in temperatures and any known allergen. 2. Do not take sinarest more then three times a day. 3. Use XXXXXXX warm water for drinking. 4. Take steam inhalation twice daily - Take hot water in a vessel, put eucalyptus oil in it. Inhale it by covering yourself with a blanket. See to it that fans/AC are not on during this and after some time also i.e. around 10-15 minutes. 5. Avoid all irritants like perfumes, soot, etc. 6.Application of warm cloth, hot water bottle or gel pack to face for 5-10 minutes will also help. 7.Use nasal decongestant or steroid drops or sprays for decongestion which encourages drainage.
