General rules for stopping aciclovir
When prescribed for an active viral infection, the most important rule is to complete the full course of treatment as directed by your healthcare provider, even if your symptoms begin to clear up. Stopping too early, or missing doses, can lead to the infection not being fully treated, which could make it more difficult to treat in the future. Always follow your doctor's instructions for the specific duration and administration. For some conditions, aciclovir is used as a daily suppressive therapy, which is taken long-term to prevent frequent outbreaks. The appropriate time to stop this suppressive therapy should always be discussed with a healthcare provider.
When to stop aciclovir for specific infections
The duration of aciclovir therapy is not one-size-fits-all and is determined by the infection and the patient's immune status. Always refer to your healthcare provider's specific instructions, but here are general guidelines based on common use cases.
Oral aciclovir for genital herpes
- Initial outbreak: For a first episode of genital herpes, oral aciclovir is typically taken for a specified period, depending on the severity and prescribed regimen.
- Recurrent outbreaks: For episodic treatment, therapy is started at the earliest sign of symptoms and the duration is determined by a healthcare professional.
- Suppressive therapy: To prevent frequent recurrences, some individuals take aciclovir daily. The duration of this therapy is determined by a doctor and may be re-evaluated periodically.
Topical aciclovir for cold sores
- Topical cream: For cold sores, apply the cream to the affected area as directed by a healthcare professional. Follow the instructions regarding frequency and duration of application. If the sore has not healed within the recommended timeframe, you should stop and consult your doctor.
Oral aciclovir for shingles (herpes zoster)
- Treatment course: For shingles, oral aciclovir is typically taken for a specific duration, with therapy often beginning within a certain period of the rash's onset for optimal effect.
Oral aciclovir for chickenpox
- Treatment course: For chickenpox, the typical course for adults and children is a specific number of days. Treatment is often most effective when started within a certain timeframe of the rash first appearing.
What happens if you stop aciclovir too soon?
Discontinuing aciclovir prematurely can have negative consequences, particularly if you are in the midst of an active outbreak. The virus can rebound, and symptoms may return or worsen. For individuals on suppressive therapy, stopping can lead to a return of more frequent outbreaks. While there are no withdrawal symptoms associated with stopping aciclovir, the risk of symptom resurgence is a significant concern.
Reasons to stop aciclovir early
Although it is important to complete a prescribed course, there are certain situations where you should stop taking aciclovir immediately and seek medical attention. These include:
- Severe allergic reactions: Symptoms such as difficulty breathing, swelling of the face, lips, tongue, or throat, or hives.
- Signs of kidney damage: Back or side pain, change in the amount of urine, or mental/mood changes.
- Neurological side effects: Confusion, hallucinations, or seizures.
Key considerations for aciclovir therapy
- Stay hydrated: Drinking plenty of water is important while taking aciclovir, as it helps support kidney function.
- Do not double up: If you miss a dose, take it as soon as you remember. However, if it is almost time for the next dose, skip the missed one and continue your regular schedule. Do not take a double dose to catch up.
- Consult your doctor: Always consult your healthcare provider or pharmacist if you are unsure about when to stop your medication, or if your symptoms do not improve or get worse.

Conclusion
Knowing when to stop using aciclovir is not a matter of simply ending treatment when you feel better. The timing is a critical component of successful antiviral therapy, and it is determined by the specific viral infection, the severity of the outbreak, and whether the treatment is for an active infection or suppression. For most acute infections, the prescribed course must be completed in full to prevent a relapse. For serious side effects, immediate cessation and medical consultation are required. As with any medication, close communication with your doctor or pharmacist is the best way to ensure proper and safe use.
