How to Apply:
Take 2 tablets of Doans PM by mouth with a full glass of water.
The medication should be taken before bedtime, as it may cause drowsiness.
Do not exceed the recommended dosage of 2 tablets per night.
The tablets should be swallowed whole; do not crush, chew, or break them.
Missed Dose:
If you miss a dose of Doans PM, take it as soon as you remember. However, if it is nearly time for your next dose, skip the missed dose. Do not take two doses at once to make up for a missed one.
Overdose:
Overdosing on Doans PM can be dangerous. If you suspect an overdose, contact your healthcare provider or the nearest poison control center immediately. Symptoms of overdose may include extreme drowsiness, confusion, difficulty breathing, or irregular heartbeat.
Doans PM works through a combination of pain relief and sedation. Here’s how each of the active ingredients works:
Magnesium Salicylate:
This ingredient works by inhibiting prostaglandins, chemicals in the body that cause pain and inflammation. By reducing these chemicals, magnesium salicylate helps alleviate pain and swelling in muscles and joints.
It is particularly effective for managing mild to moderate muscle pain and back pain that may occur due to overexertion, strains, or minor injuries.
Diphenhydramine:
Diphenhydramine is primarily used as an antihistamine to treat allergy symptoms, but it also has sedative properties. When taken in this combination, it can help promote drowsiness and make it easier to fall asleep, which is especially useful for individuals whose pain keeps them awake at night.
It works by blocking certain histamine receptors in the brain that help regulate wakefulness, causing a relaxed and sleepy feeling.
Together, these ingredients help reduce pain and inflammation, while also helping you fall asleep more easily, thus improving your quality of rest during the night.
Like all medications, Doans PM can cause side effects. Some common side effects include:
Drowsiness: While this is intended, it may interfere with daytime activities if you do not get enough sleep.
Dizziness: You may feel lightheaded or dizzy, especially when standing up too quickly after taking the medication.
Dry Mouth or throat.
Upset Stomach or nausea.
More serious side effects may include:
Severe allergic reactions (rash, itching, swelling, trouble breathing).
Difficulty urinating or confusion (especially in older adults).
Severe dizziness or fainting.
If you experience any of these serious side effects, seek medical attention immediately.
Other Sedatives or Sleep Aids: Taking Doans PM with other sedative medications, such as benzodiazepines (e.g., Valium), can lead to excessive drowsiness or even respiratory depression. Always consult with a healthcare provider before combining medications that promote sleep or relaxation.
Alcohol: Drinking alcohol while using Doans PM can increase the sedative effect of diphenhydramine, making you feel excessively drowsy and impairing your ability to perform tasks like driving.
Antihistamines: Taking other antihistamines at the same time can increase the likelihood of drowsiness and other side effects.
Blood Thinners: The NSAID in Doans PM, magnesium salicylate, can interact with blood thinners (e.g., warfarin), potentially increasing the risk of bleeding.
Other Pain Relievers: Do not combine Doans PM with other NSAIDs (e.g., ibuprofen, naproxen) unless directed by a healthcare professional, as this can increase the risk of gastrointestinal irritation or ulcers.
Always consult a healthcare provider before using Doans PM if you are taking other medications, especially sedatives or anticoagulants, to avoid potential interactions.
Doans PM is available over-the-counter (OTC), so you do not need a prescription to purchase it. However, if you have chronic pain, sleep disturbances, or other underlying health conditions, it’s always a good idea to speak with your healthcare provider to ensure that Doans PM is the right solution for you.
