Precautions:
- Take naproxen with food, milk, or an antacid to lessen stomach upset.
- Do not crush or chew any extended-release forms of naproxen. Swallow them whole. They are specially formulated to release slowly in your body. Ask your pharmacist if you do not know if you have an extended-release formulation.
- Watch for bloody, black, or tarry stools or blood in your vomit. These symptoms could indicate damage to your gastrointestinal tract.
- If you drink more than three alcoholic beverages a day, naproxen may increase the risk of stomach bleeding
- Avoid prolonged exposure to sunlight. Naproxen may increase the sensitivity of your skin to sunlight. Use a sunscreen and wear protective clothing when exposure to the sun is unavoidable.
- Use caution when driving, operating machinery, or performing other hazardous activities. Naproxen may cause dizziness. If you experience dizziness, avoid these activities.
Pregnancy and Breastfeeding:
- FDA pregnancy category B. This means that it is unlikely to harm an unborn baby. Naproxen should not be taken late in pregnancy (the third trimester) because a similar drug is known to affect the baby's heart. Do not take naproxen without first talking to your doctor if you are pregnant.
- Naproxen passes into breast milk and may harm a nursing infant. Do not take this medicine without first talking to your doctor if you are breast-feeding a baby.
