Valacyclovir works very well for the treatment of cold sores and genital herpes. Like most medications, Valacyclovir may cause side effects in some individuals.
Common side effects include:
- Nausea and vomiting
- Headache
- Dizziness
- Abdominal pain
- Diarrhea
- Skin rash
- Fatigue or weakness
Most of these side effects are generally mild and go away on their own without any specific treatment. However, if any of these side effects persist or become bothersome, it’s essential to inform your healthcare provider.
In rare cases, Valacyclovir can cause more serious side effects that require immediate medical attention. If you experience any of the following severe side effects, seek medical help right away:
- Allergic reactions: Signs may include rash, itching, swelling of the face, lips, tongue, or throat, severe dizziness, and difficulty breathing.
- Unusual bruising or bleeding: Valacyclovir can affect the blood’s clotting ability in some cases.
- Kidney problems: Symptoms may include change in the amount of urine, back/side pain, or signs of dehydration.
- Neurological symptoms: Rarely, some people may experience confusion, hallucinations, tremors, or seizures.
It’s essential to take Valacyclovir as prescribed by your doctor and inform them about any other medications or supplements you are taking to avoid potential drug interactions. If you have a history of kidney problems or immune system issues, let your healthcare provider know, as they may need to adjust the dosage or monitor your condition more closely.
