What is Nyquil?

Nyquil is an over-the-counter nighttime cold and flu medication manufactured by Johnson & Johnson. The active ingredients in Nyquil are acetaminophen and doxylamine succinate (an antihistamine). The medication is meant to relieve the symptoms of colds, such as a stuffy or runny nose, cough, headache, and fever. The effects of doxylamine can last between 6 and 10 hours, which is why this is the most common time frame for people to take it.

For that reason, you should avoid taking it after gastric bypass surgery. The risk of kidney damage is particularly high if you take more than the recommended dose of acetaminophen.

The antihistamine in Nyquil causes drowsiness, and both the antihistamine and acetaminophen are also very mild (but effective) stimulants. The combination of these two effects can cause you to feel very sleepy. And if you’re already a light sleeper, loud noises could wake you up enough to interrupt your sleep cycle.

Safer Options


Excedrin: This pain reliever and fever reducer is a safe alternative to aspirin and acetaminophen after surgery. It’s also less likely to cause irritation in your stomach.

Tylenol: This is another safe alternative to aspirin and acetaminophen. Like Excedrin, it’s less likely to cause irritation in your stomach than some other pain medications.

Ibuprofen: This medication is another option for pain relief, but only after your first post-surgical week.

Acunelix: This prescription medication is specifically for pain relief in patients with gastric bypass.

Melatonin: This is a hormone that promotes sleep. It’s completely safe to take after gastric bypass surgery. Unlike antihistamines, melatonin does not cause drowsiness.

 

Sleep soundly after surgery:You may be sleeping more soundly after gastric bypass surgery, but that doesn’t mean you’re sleeping more efficiently. You may actually be spending more time in light sleep than deep sleep, which doesn’t promote healing. To improve your sleep quality after gastric bypass surgery, you may want to consider a sleep aid like Lunesta or Sleep IQ.

 

Conclusion
