If you are unable to keep fluids down or vomiting continues, this may require medical advice.

Severe Abdominal Pain

Persistent or intense abdominal pain, especially if it does not improve, should not be ignored.

Signs of Dehydration

Symptoms such as dizziness, dry mouth, or reduced urination may indicate dehydration.

Unusual or Worsening Symptoms

If something feels different from expected side effects or continues to worsen, it is important to seek advice.

When Should You Seek Medical Advice?

If symptoms are severe or do not improve
If you cannot keep fluids down
If you experience significant pain or discomfort
If you are unsure whether symptoms are normal

Should You Stop Treatment?

If you experience serious or concerning symptoms, it may be appropriate to pause treatment and seek medical advice.

Do not continue treatment if you are unsure about your symptoms.
