Can Voltaren make you feel weird?

Voltaren is a medication that is commonly used to relieve pain and reduce inflammation in conditions such as arthritis, muscle sprains, and menstrual cramps. It belongs to a class of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs) and contains the active ingredient diclofenac. While Voltaren is generally well-tolerated by most individuals, some people may experience certain side effects that can make them feel “weird” or uncomfortable. In this blog post, we will explore the common and less common side effects of Voltaren, factors that may contribute to feeling weird after taking the medication, and tips for managing these side effects.

Common Side Effects of Voltaren

Upset stomach

One of the most common side effects of Voltaren is an upset stomach, which may include symptoms such as nausea, heartburn, and stomach pain. This is because NSAIDs can irritate the lining of the stomach, leading to inflammation and discomfort. Taking Voltaren with food or milk can help reduce the risk of developing an upset stomach.

Diarrhea and constipation

In some cases, Voltaren can cause changes in bowel movements, leading to either diarrhea or constipation. These side effects typically resolve on their own once the medication is discontinued. Staying hydrated and eating a balanced diet can help regulate bowel movements while taking Voltaren.


Another possible side effect of Voltaren is a headache. This may be due to the medication’s effects on blood vessels and the central nervous system. If you experience a persistent or severe headache while taking Voltaren, it is advisable to consult your doctor for further evaluation and possible alternative treatments.

Less Common Side Effects of Voltaren


While drowsiness is not a common side effect of Voltaren, some individuals may experience this symptom after taking the medication. It is important to be cautious when driving or operating heavy machinery if you feel excessively drowsy after taking Voltaren. If drowsiness becomes a persistent issue, consult your healthcare professional for further guidance.


Voltaren may also cause dizziness in some individuals. This can be due to the medication’s impact on blood pressure and the inner ear. It is important to avoid sudden movements and take your time when getting up from a sitting or lying position to minimize the risk of falls. If dizziness persists or worsens, seek medical advice.

Blurred vision

Blurred vision is a less common side effect of Voltaren but can occur in some individuals. If you experience any changes in your vision after taking the medication, it is advisable to consult your doctor for further evaluation. They may recommend adjusting the dosage or considering alternative treatment options.

Factors Contributing to Feeling Weird After Taking Voltaren

Several factors can contribute to feeling weird or experiencing side effects after taking Voltaren. These include:

Individual Sensitivity to the Medication

Each person’s body reacts differently to medications, including Voltaren. Some individuals may be more sensitive to its effects, leading to a higher likelihood of experiencing side effects. If you have a history of sensitivity to NSAIDs or other medications, it is important to discuss this with your doctor before starting Voltaren.

Interaction with Other Medications or Substances

Taking Voltaren in combination with certain other medications or substances can increase the risk of side effects. It is essential to inform your healthcare provider about all the medications, supplements, and herbal products you are taking to avoid potential interactions. They can advise you on the appropriate use and potential adjustments needed to minimize the risk of side effects.

Improper Dosage or Administration

Taking Voltaren at a higher dose than prescribed or for a longer duration than recommended can increase the likelihood of experiencing side effects. It is crucial to follow the instructions provided by your healthcare professional and not exceed the recommended dose. If you have any concerns about the dosage or administration of Voltaren, consult your doctor or pharmacist.

Tips for Managing the Side Effects of Voltaren

While experiencing side effects from Voltaren can be uncomfortable, there are several tips to help manage and minimize these effects:

Take with Food or Milk to Reduce Stomach Upset

To reduce the risk of an upset stomach, it is advisable to take Voltaren with food or milk. This can help create a protective barrier in the stomach and reduce irritation caused by the medication. However, avoid taking it with high-fat meals, as this may slow down the absorption of the drug.

Stay Hydrated to Minimize Constipation

If you experience constipation while taking Voltaren, ensure you stay hydrated by drinking plenty of water and consuming fiber-rich foods. Adequate hydration can help soften the stool and facilitate regular bowel movements. If constipation persists, speak to your healthcare provider for further guidance.

Avoid Alcohol or Certain Medications that May Exacerbate Drowsiness or Dizziness

Since Voltaren can cause drowsiness or dizziness in some individuals, it is best to avoid alcohol or other medications that can intensify these effects. Be aware of any potential interactions and consult your healthcare provider if you have any concerns.

When to Seek Medical Attention

While most side effects of Voltaren are generally mild and resolve on their own, there are situations where medical attention should be sought:

Persistent or Severe Side Effects

If you experience persistent or severe side effects from Voltaren, it is important to consult your doctor. This includes symptoms such as severe stomach pain, persistent headaches, or prolonged drowsiness.

Allergic Reactions or Signs of Anaphylaxis

In rare cases, some individuals may experience an allergic reaction to Voltaren. Seek immediate medical attention if you develop symptoms such as rash, itching, swelling, severe dizziness, or difficulty breathing.

Worsening Symptoms Over Time

If your symptoms worsen or do not improve with time, it is advisable to consult your healthcare provider. They can evaluate whether Voltaren is the appropriate medication for your condition or recommend alternative treatments.


Understanding the potential side effects of medication is important for managing and optimizing your healthcare. While Voltaren can be an effective pain relief medication, some individuals may experience side effects that can make them feel “weird” or uncomfortable. The common side effects of Voltaren include upset stomach, diarrhea, constipation, gas, headache, while less common ones include drowsiness, dizziness, and blurred vision. Factors contributing to feeling weird after taking Voltaren include individual sensitivity, interactions with other medications or substances, and improper dosage or administration. By following the tips for managing side effects and knowing when to seek medical attention, you can safely and effectively use Voltaren for pain relief. Always consult your healthcare professional for any concerns or questions regarding the use of Voltaren or any other medication.
